Helix Code Update History

v1.5.39 · 2026-11-04​

Summary​

  • Helix: Settings gains a Browser Automation card that switches between auto / my Chrome / dedicated / headless modes, with a status badge and setup guidance, plus one-click opening of Chrome's debug switch page; this release also fixes the mobile case where the newest answer stayed hidden after returning from background, a 1280×645 portable-display layout issue where the details overlay filled the window and covered the session list, and a three-pane tier that missed 0.5 px on filled 2x displays
  • Helix-agent: The interactive browser can drive your everyday Chrome through the chrome://inspect remote debugging switch (reusing the signed-in session, no restart, no extra instance), or run a dedicated browser with a persistent profile; list_tabs/fetch_tab no longer hang on very large tab sets, frozen background tabs, or a Chrome bound only to the IPv6 loopback

Helix​

  • New: Browser Automation card in Settings — auto / my Chrome / dedicated / headless modes with a status badge, unavailable-reason text, and setup guidance
  • New: The guide can open Chrome's debug switch page in one click, then polls status so the badge updates as soon as the switch is turned on
  • Improved: Reading existing tabs always uses your own browser regardless of the access mode (noted on the card)
  • Fixed: On mobile, returning from background could leave the newest answer hidden behind a permanent spinner until the app was restarted — resume reconciliation now finalizes or discards the stale mid-stream tail copy left behind by the background
  • Fixed: On a 1280×645 portable display the chat details overlay expanded from the bottom, filled the window, and covered the session list — short viewports now use a scrollable bottom drawer capped at 82% height, and the desktop tier is width-limited and centered
  • Fixed: The three-pane tier never matched 1279.5 logical width on a filled 2x display; the breakpoint is relaxed to 1272
  • Improved: The main window minimum size is tightened to 1024×600, so it can no longer be dragged into the narrow tier or become too short for the composer
  • Fixed: Dedicated browser mode no longer shows the chrome://inspect remote-debugging guide

Helix-agent​

  • New: Three interactive browser access modes — live drives your everyday Chrome through the chrome://inspect remote debugging switch (reusing the signed-in session, no restart, no new instance); dedicated keeps a visible browser with a persistent profile; headless stays the previous behavior
  • New: Browser automation settings and status endpoints GET/PUT /api/settings/browser (status is discovery only and never triggers the authorization prompt)
  • New: POST /api/settings/browser/open-inspector opens Chrome's debug switch page in one click (fixed address, no external input)
  • Improved: list_tabs/fetch_tab now enumerate targets via Target.getTargets and attach only to the selected tab, so very large tab sets no longer hang; frozen background tabs are brought to the foreground and retried
  • Fixed: Support Chrome that listens only on the IPv6 loopback — 9222 probing and the CDP connection try 127.0.0.1 and [::1] in turn
  • Fixed: The shared live/dedicated connection was cancelled immediately (context canceled), which broke both access modes

v1.5.38 · 2026-11-03​

Summary​

  • Helix: A systematic performance pass over the chat page — page-level rebuild isolation, frame-by-frame viewport mounting, and caching for per-frame O(n) work make typing, scrolling, and switching back feel noticeably snappier on long and 10k-message sessions; this release also removes the two-second wait when returning to a long session, the false "tasks still running" quit warning, tables jumping in height mid-stream, and the viewport being yanked away when a turn finishes, and adds mobile muscle memory, two-channel task avatars (type + status), desktop completion alerts, and health warnings
  • Helix-agent: The completion event stream now probes liveness in both directions so mobile background notifications no longer go silent on half-open connections; job_wait caps a single wait at 180 seconds and reports timezone-aware timestamps, and adds session search, cross-session resume, and three-tier WeChat token recovery

Helix​

  • Improved: Chat page performance pass — dragging the divider or switching panel tabs no longer rebuilds the chat area and session list, and long-task progress no longer rebuilds the message viewport
  • Improved: Synchronous work per streaming frame drops from roughly 10 ms to roughly 2 ms, and creating a new session no longer rebuilds the whole tree
  • Improved: The chat viewport mounts frame by frame — the first frame takes only one viewport of span, then tops up frame by frame while scrolling yields, so the first screen appears sooner
  • Improved: Windowed first-frame mounting drops from 40 rows to 20, with a bottom-pinned top-up that keeps the viewport covered
  • Improved: Per-frame O(n) work on 10k-message sessions is now cached (windowed projection and floors), so scrolling and streaming no longer recompute everything on every frame
  • Improved: The session disk cache builds its JSON in shards, and the cache-root path bug is fixed (the disk cache had never actually been in use before)
  • Improved: Returning to a long session no longer waits for the background reload before dropping the overlay — a memory-cache hit shows content two frames later while the background reconciliation keeps running
  • Improved: Task avatars split into two channels — the container answers "what is it" (type color) and a corner badge answers "how is it" (status), so a stopped task no longer looks failed
  • Improved: A paused session no longer shows a resume button; unexpected interruptions and manual stops share one "Continue" entry
  • Improved: The desktop app now consumes machine-level completion events, so completion alerts no longer depend on the session stream subscription
  • Improved: The top action area is quieter — ghost buttons, semantic grouping, and a three-step status pill; the right tool panel floats over content instead of squeezing it
  • Improved: The file-sync entry becomes an action row with an icon and the target path
  • Improved: The health warning icon in the top bar only appears when something is wrong, and WeChat token status is surfaced
  • Improved: The sound bell moves into the window top control strip and becomes the single gate (completions always play, no longer muted by the notification switch)
  • Improved: The chat details panel is redesigned as grouped cards
  • Improved: Mobile muscle memory — back key, session search, message action panel, new-content dot, and iOS edge back gesture
  • Improved: Multi-tunnel address self-healing and one effective address — REST and WebSocket use the same address after probing, and route selection is consistent
  • Fix: The quit confirmation no longer falsely reports "N workspaces still running tasks" — it now trusts server status and drops sessions it confirms idle
  • Fix: Half-open self-healing for the completion event stream — client liveness probing, rebuild on foreground and network change, and subscription backoff
  • Fix: Backfilling the latest messages on foreground is no longer blocked by the WebSocket reconnect and status polling
  • Fix: The mobile session list no longer writes reactive state during build (red screen)
  • Fix: Tables take their shape during streaming, so finishing a sentence no longer makes the view jump
  • Fix: Finishing a turn no longer yanks the viewport you are reading (anchor-row compensation when the focused summary card collapses)
  • Fix: Windowed long sessions no longer jitter up and down during generation (the projection window is no longer reset by bottom-pinning)
  • Fix: Reading upward on mobile is no longer dragged back to the bottom by bottom-pin and overscroll re-entry
  • Fix: Accent-on-tint depth is computed from the card's real background, so text and icons stay legible on light cards

Helix-agent​

  • New: Bidirectional liveness on the event stream — the server pings every 30 seconds with a 90-second read timeout, and clients rebuild on a liveness check and advertise the event_pong capability
  • New: Session search and cross-session resume — session_list supports keyword search and session_history supports reading only the tail, so a new session can pick up where an old one left off
  • New: Three-tier WeChat session token recovery and a health-issues aggregate endpoint
  • Improved: job_wait caps a single wait at 180 seconds and returns an "observe progress first" hint instead of blocking indefinitely
  • Improved: job_wait results carry timezone-aware timestamps and a task timeline (started, finished, elapsed)

v1.5.37 · 2026-10-26​

Summary​

  • Helix: Closing the desktop window now tucks Helix into the menu bar (tray residency) with a pre-quit task check, interjection queue entries can be turned into a side chat (forking a session that is still running), truncated downloads are no longer silent and resume automatically, manager-mode UI and composer entries are aligned, document preview (PDF / Office), mobile keep-alive connection plus completion notifications, a reworked Codex workbench, and a large batch of desktop and mobile interaction and rendering fixes
  • Helix-agent: Interjections hand in-flight tools over to background jobs that keep running with live output and a stop action, forking a session that is still running, a machine-level completion event stream with mobile push, an incremental background-task list protocol, remote download truncation and resume fixes, gateway service_addr self-healing, server-side document preview rendering, and a rewritten prompt that pushes background tasks in parallel

Helix​

  • New: Closing the desktop main window tucks Helix into the menu bar; the tray menu offers Show Main Window / Running Status / Quit, and quitting asks for confirmation when agents or scheduled tasks are still running, with a full rollback if you cancel
  • New: Interjection queue entries can be converted into a side chat — a separate session is forked at the last completed turn while the original keeps running untouched
  • New: The manager-mode new conversation page lets you pick the executing agent first; the composer is condensed into a model chip plus "Executing agents · N", and the draft agent selection still applies once the session is created
  • New: Download integrity and automatic resume — length validation, Range resume, and If-Range to prevent concatenation corruption; truncation failures are no longer silent and can be retried directly
  • New: Document preview — PDF renders as page images with an install guide for the required component, and docx / pptx / xlsx route to Office preview
  • New: Mobile keep-alive connection and local completion notifications — the client consumes machine-level completion events, so notifications are no longer tied to the current workspace
  • New: Settings exposes the full reviewer-model configuration chain, and review subagents show a badge
  • New: File tree context menu gains "Save As" so the file name can be chosen before downloading
  • Improved: Background tasks — the detail view streams live output (1-second polling), the recently finished list shows completion timestamps and rounded durations, and the task view is consolidated into the project panel (the duplicate task tab in the right panel is removed)
  • Improved: Manager-mode progress and status UI aligned — cancellation no longer claims completion, the running state converges on a single stop entry, status and waiting bars share one spec, and the board entry is filled in
  • Improved: Desktop layout — the title bar background matches the sidebar color so the seam is gone, panels keep their internal state when collapsing across breakpoints, panel collapse is animated too, and the composer max width narrows to 800
  • Improved: Pressing Send while recording now stops recording and sends; Cmd/Ctrl+Shift+Enter sends an immediate interjection
  • Improved: Thinking block and usage bar top/bottom padding are aligned, the bottom usage bar spreads edge to edge, and context usage becomes a ring
  • Improved: Session lazy loading — floor navigation can jump into unloaded turns, the loading mode is auto-selected by session size, missing segments load on click while keeping the reading position, and disk-cache encoding/decoding moved off the main isolate
  • Improved: File search renders progressively as a stream, with groups collapsed by default
  • Improved: File transfers are queued serially — busy upload/download no longer greys out actions, and cancel clears the queue too
  • Improved: Mobile list and chat pages — the permanent row menu button becomes a long-press menu, header info moves into the AppBar subtitle, new conversation becomes a bottom-right floating button, the model menu is height-capped and scrollable, the composer follows the keyboard, and dragging the message list dismisses the keyboard
  • Improved: Codex pages — the list structure aligns with the home page, polling backs off when idle and pauses in the background, new conversations focus the input, and messages can be sent while a turn is running
  • Improved: Selection states unified around a neutral wash with a bar; file tree, sessions, Git, and Studio now share one selection language
  • Improved: Multiple tunnel addresses are listed individually with the primary gateway preferred
  • Improved: The web build aligns with the desktop shell and theme split, and the blank web settings page is fixed
  • Improved: Reconnect recovery — state inspection uses the history_seq anchor to backfill missed messages, event cursors detect gaps and reconnect with since_seq, and streams redraw on retry
  • Fix: Background task "ghost rows" — batch summary events no longer create task rows without a timestamp
  • Fix: The manager-mode thinking block kept flickering (waiting state rewritten every frame plus unstable streaming row render keys)
  • Fix: The ask_user choice card frequently reported "pending content could not be loaded"
  • Fix: Android crashed on launch (media_kit cross-process reference files triggered on pid reuse)
  • Fix: Tapping a mobile notification did not open the matching session (route retries by result, three-state permission status)
  • Fix: A cancelled subtask no longer reports a red failure (terminal state trusts the backend status, text fallback is only for silencing)
  • Fix: Three root causes of lost streaming content (content dedupe / step boundaries / done authority)
  • Fix: The last row did not stick to the bottom when rendering finished, and overscroll bounce/upward-drag detection is corrected
  • Fix: Image preview now refreshes when the file changes externally and supports SVG rendering
  • Fix: macOS screen-recording permission — preflight plus guidance before capture, with a proper retry after granting
  • Fix: Cancelling the execution-machine picker now aborts session creation
  • Fix: SnackBars with action buttons auto-dismiss again
  • Fix: Runtime notes for tools moved to the background were emitted twice
  • Upgrade: Flutter dependencies upgraded within constraints (62 packages)
  • Cleanup: Removed 544 unreferenced translation keys, 16 unreferenced files, and three superseded legacy pages

Helix-agent​

  • New: An immediate interjection now hands in-flight tools over to background jobs — no more waiting it out or killing the process; a synthetic result is written back to history telling the model not to rerun, and the job supports live output and Stop
  • New: Sessions that are still running can be forked (automatically cut at the last completed turn), powering the client side chat
  • New: Machine-level completion event stream — persisted to disk, broadcast, and replayed after reconnect, powering mobile completion notifications
  • New: Mobile push service — a device registry plus APNs / Xiaomi push channels; flipping a switch no longer wipes credentials
  • New: Session turn outline endpoint /turns, and the status endpoint returns the history_seq anchor
  • New: Incremental background-task list protocol (rev / srcs / changed / removed); the remote task watcher migrates to incremental consumption with concurrent queries
  • New: Server-side document preview rendering — PDF page rendering plus on-demand LibreOffice component installation
  • New: Multiple tunnel gateways with a shared subdomain ID; a second gateway ships built in and upgraded clients backfill it automatically
  • New: Reviewer subagent type with a deterministic review checklist and dedicated reviewer models
  • New: Built-in web_search tool
  • Improved: Prompts now push background tasks in parallel — once a task is backgrounded, keep making progress and treat blocking waits as a last resort
  • Improved: Remote downloads — the 5-minute cap is gone, Content-Length is preserved, If-Range and 416 are passed through, and a first-packet timeout is added
  • Improved: Gateway self-healing — a changed service_addr re-registers automatically, data-plane failures re-push with exponential backoff
  • Improved: Session snapshots are read once (messages and last_event_seq share one read)
  • Improved: Content search streams results, and maxResults becomes a per-file cap
  • Improved: WebSocket event sequence and epoch with a ring buffer for disconnect replay
  • Improved: The Codex shared engine is on by default (attaches to the Codex daemon), and sending while a turn runs becomes a steer append
  • Improved: MCP connections self-heal, and foreground execution gets a grace period after timeout/cancel so escaped grandchild processes no longer hold the call
  • Improved: lightagent remote Office runtime (on-demand download with readiness gating)
  • Fix: The backup gateway stayed "offline" — an unpublished service_addr caused 502 machine unavailable
  • Fix: may_background no longer duplicates the interjection-to-background job, and adopted may_background jobs can now be stopped
  • Fix: Cancelled subtasks finish as "cancelled" instead of being reported as failures
  • Fix: Credential redaction covers all-caps, abbreviated, and trailing-digit key names
  • Fix: ask_user validates parameters and parses tolerantly, so invalid choice cards no longer block the user
  • Fix: A remote job_wait response can be interrupted by an interjection, and remote cancellation no longer advances the output cursor
  • Fix: officeruntime unpacking symlink escapes (switched to os.Root with real-path re-checks)
  • Upgrade: Go 1.26 and direct dependency upgrades
  • Cleanup: Removed roughly 5.5k lines of confirmed dead code

v1.5.36 · 2026-10-09​

Summary​

  • Helix: Codex runtime integration (app-server provider plus Desktop thread browsing and a live viewer), Agent Browser persistent interactive browsing (shared page controls with live preview frames), a mobile chat information-density and navigation overhaul, interjection "send immediately" reliability fixes, real-time context-usage fixes, and BYOK custom models plus request-body gzip compression, among many improvements
  • Helix-agent: Codex app-server provider and remote session bridge, persistent interactive browser tools (browser_open/observe/click/fill/press/scroll/close), automatic wake-up when remote-bound sessions' background tasks complete, a built-in web_search tool, cua-driver upgraded to v0.31.0, and manager async dispatch (interruptible waits plus control tools)

Helix​

  • New: Codex runtime integration — a new Codex app-server provider runs sessions through the locally logged-in Codex CLI; a device-level sidebar entry, embedded session timeline browsing, and preserved live reading state
  • New: Codex Desktop thread browsing and live viewer — browse local Codex history threads and follow new messages live
  • New: Agent Browser persistent interactive browsing — one isolated Chromium page per session where tools and the preview panel observe the same page; a direct Browser panel entry renders live page frames, and the expanded viewer keeps following new events
  • New: Shared page controls — the browser panel ships open/observe/click/fill/press/scroll/close actions
  • New: Manager async dispatch UI — task bar visualization, cancel and interject entry points, and receipt presentation
  • New: File browser entry on mobile, tablet, and narrow windows
  • New: BYOK wizard supports custom models (no longer forces preset selection); provider config gains a request-body gzip compression toggle (off by default)
  • Improved: Mobile chat page information density and navigation overhaul — condensed top-bar actions and a tighter layout
  • Improved: Tablet page customization — shell and layout criteria are now width-driven instead of platform-driven (draft preserved when the shell switches)
  • Improved: Mobile cold start always lands on the session list, the completion picker picks main sessions only, and the full-page header is a single line; the bottom session bar is simplified (usage bar on one line, steady connected state no longer takes space, attachment button iconized)
  • Improved: Touch file-tree accidental-move protection — drag-to-move is disabled in favor of a long-press "Move to…" menu with a target folder picker
  • Improved: Chat-page spinner convergence — tool cards keep only the timer and background-task pills show only a count
  • Improved: Background task details now show the input (full command plus working directory)
  • Improved: Tool-card execution timer is computed from message receipt time, so it no longer resets when switching pages
  • Improved: Empty-state sidebar gains Settings/User Center entries; message card borders softened, status badges unified, composer toolbar slimmed
  • Improved: Android pauses local environment startup and cold-starts straight into remote UI
  • Fix: Interjection "switch to send immediately" reliability — enqueue receipts align with local intent, wake-up and idle compensation, in-flight operation interception, and visible failures
  • Fix: Context usage prefers real-time values and clears ownership on session switch (no more stale values)
  • Fix: Mobile session list no longer degrades multi-project groups into a single project (full-page mirror source workspace scope)
  • Fix: Hidden the duplicate full-page back button on mobile, and touch scrolling no longer rebuilds the whole table
  • Fix: Markdown math node rendering — fixes "Unknown: inline_math" and price ranges being treated as formulas
  • Fix: Download stream errors now surface the real cause instead of being masked by "File closed"
  • Fix: Image capability gating now uses unique-suffix matching plus directory backfill (single-flight with a 30s cooldown)

Helix-agent​

  • New: Codex app-server provider and remote session bridge — automatically discovers the local Codex Desktop runtime and browses/live-views Desktop threads; bounded history payloads for the live viewer and warm history snapshots
  • New: Persistent interactive browser use — the browser_open/observe/click/fill/press/scroll/close tool set with one isolated Chromium page per workspace/session; shared page controls; live CDP preview frame streaming
  • New: Automatic wake-up when remote-bound sessions' background tasks complete — a remote task watcher delivers results and wakes the session when a remote lightagent job reaches a terminal state
  • New: Built-in web_search tool
  • New: Manager async dispatch — interruptible longterm waits plus control tools (cancel background job / send to subagent) and stop/receipt semantics fixes
  • New: BYOK provider use_gzip request-body compression (off by default) with compression status logging
  • New: local_file_read is no longer directory-restricted (read-only access to arbitrary absolute paths on the host)
  • Improved: Session token snapshots refresh on every response and reset after compression, with read-write lock coverage completed
  • Improved: inferModelSupportsImages now covers mimo-v2.6 (excluding TTS variants), aligned with audio inference

  • Fix: User-cancelled tools write a cancellation result with elapsed time into LLM history
  • Fix: Download gzip skip is now sticky, fixing stream corruption on large media downloads
  • Upgrade: Embedded cua-driver upgraded to v0.31.0 (list-tools protocol and check_permissions JSON parsing adaptation)

v1.5.35 · 2026-09-23​

Summary​

  • Helix: Session message disk cache (lazy mode cold-start opens instantly), draggable interjection queue reordering, direct audio understanding (supports_audio voice recording sent directly, plus direct image URL sending), voice message infinite-loop playback fix, Markdown display repair pipeline, provider brand icon system, and checkpoint change chips among many UX improvements
  • Helix-agent: Tool-call client timeouts/reconnect/liveness probing (a hung remote machine no longer hangs forever), session file change checkpoints (P1), audio input capability flag and audios message pipeline, interjection queue reorder protocol, and mcp-go upgraded to v1.1.0

Helix​

  • New: Lazy-mode session message disk cache — cold-start opens instantly with per-session JSON + index storage (append-only segments); the Settings page shows "Session cache" usage with one-click cleanup and 1GB LRU auto-eviction
  • New: Draggable interjection queue reordering — drag to reorder interjections with server-authoritative state convergence; reorder protocol guards against jitter and misalignment
  • New: Direct audio understanding — models with audio input support (supports_audio) send recordings directly, falling back to ASR on failure without losing the recording; audio capability badge shown
  • New: Direct image URL sending — supports_image_url toggle with upload-to-URL on send
  • New: Provider brand icon system — provider icons in session rows, brand icons on the BYOK page, and capability badges on model rows, with real SVG logos for 9 brands
  • New: Full composer usage bar — total usage / total requests / total hit rate (this session + sub-agents + ShellGuard combined)
  • New: Checkpoint change chip — session file change (P1) badge display
  • Improved: Voice message experience trio + brand logo system expansion; thinking body left-aligned with the collapsed row; auto-refresh is silent (only manual refresh spins) and the LLM config keeps the selected provider without jumping back; background agent detail view follows the main session's collapse display mode
  • Fix: Voice message infinite-loop playback (a bare seek(0) in the completed callback raced ahead of the mpv auto-stop and restarted playback)
  • Fix: Duplicate trailing assistant messages collapsing the last answer (append dedup + projection anchors skipping hidden duplicates)
  • Fix: Markdown display repair pipeline upgraded — structural rules + visible-content safety net, with separator-line detection aligned to GFM/renderers (validated against real corpus)
  • Fix: Session-list load failures now show a non-blocking banner instead of a raw-error SnackBar

Helix-agent​

  • New: Tool-call client timeouts/reconnect/liveness probing — a hung remote machine no longer hangs forever; health backoff fails fast and in-flight calls are probed on a separate connection
  • New: Session file change checkpoints (P1) — read-only git snapshot per turn end-state plus a record endpoint
  • New: Audio input capability flag and audios message pipeline — BYOK input_audio direct sending
  • New: supports_image_url capability field + CLI-channel URL image pollution guard
  • New: Interjection queue reorder protocol (reorder_queue) + update no longer falsely broadcasts when not found
  • Improved: Config category table + MCP/model rebuild prefix-protection guard consolidation
  • Fix: Auto-compress threshold now reserves the model's max_output_tokens

v1.5.34 · 2026-09-20​

Summary​

  • Helix Code: On-demand history loading (lazy mode) is now available — large sessions open faster and lighter; machine online probing is enhanced (mobile devices are no longer falsely marked offline); interjection display timeliness and stability are fixed; plus UX polish and desktop interaction fixes for the collapsed thinking row, single-answer sharing, and explorer root selection
  • Helix-agent: Self-host tunnel end-to-end probing with auto-restart self-healing; the reversible skill archive loop (archive/unarchive/pin/unpin); session system-prompt freezing and fork snapshot inheritance fix prefix-cache breakage; context-size control phase 2; lightagent remote write forwarding and binary-read fix

Helix Code​

  • New: On-demand history loading (lazy mode) — the "History loading mode" setting offers full (default) / lazy; in lazy mode a session opens with head/tail windows only, missing ranges load on scroll or click, so large sessions open faster with less data
  • Improved: Machine online probing — automatic retry on failure, a wider probe timeout, and re-probing when returning to foreground or on network recovery; mobile devices are no longer falsely marked offline, and offline state is clearly labeled
  • Improved: Interjection timeliness and stability — a send-protection window prevents flicker after sending an interjection, queued acknowledgments immediately rebuild list items, event-stream replace semantics are unified, and session-list refresh is throttled
  • Improved: The collapsed thinking row — the running spinner is replaced with a primary-color highlighted icon, and the "thinking" label text is removed (icon + hover tooltip remain)
  • Improved: Single-answer sharing upgraded — no title bar, no thinking content, and a unified "Generated by Helix" footer
  • Fix: Empty thinking content no longer renders an empty card (trimmed emptiness check)
  • Fix: Explorer root selection respects the user's manual choice — auto-selection no longer overrides a manually selected root
  • Fix: The top-right "More actions" menu was unclickable under the macOS unified window frame
  • Fix: The right panel was slow to open and "Manage all prompts" in the details page did not open
  • Fix: The task-output panel now scrolls by drag, and text selection no longer fights with scrolling (the selection layer was moved outside the scroll view)

Helix-agent​

  • New: Self-host tunnel end-to-end probing with auto-restart self-healing — the public endpoint is probed on a timer, consecutive failures trigger re-registration and a tunnel restart with exponential backoff, never giving up
  • New: Reversible skill archive loop — archive/unarchive/pin/unpin plus archived listing (list show_archived); archiving is not deletion and can always be undone
  • New: On-demand history loading support — the /messages endpoint exposes lightweight history_seq streaming reads so clients can detect and fetch missing ranges
  • Fix: Session system-prompt freezing — binding create/save/restore no longer rewrites the runtime system prompt, fixing the 420K-token prefix-cache breakage
  • Fix: Fork snapshot inheritance — the first request after a fork no longer breaks prefix caching
  • Fix: When a background task is dissolved by timeout, a late completion result is delivered on its own instead of being lost
  • Improved: Context-size control phase 2 — user/builtin skills now share one size budget, and shell/remote/memory tool descriptions are trimmed, further reducing starting token usage
  • Fix: lightagent remote fs/read returns metadata only for non-text files — large remote images no longer fail to open due to full-read timeouts
  • New: lightagent remote workspace write operations are forwarded (upload / create / save / rename / delete)
  • New: queued acknowledgments carry content/insert_mode so clients can display interjected entries immediately

v1.5.33 · 2026-09-14​

Summary​

  • Helix Code: The cross-platform (desktop + mobile) design overhaul has fully landed — a unified density system, condensed top-bar actions, and rebuilt mobile navigation and touch hit targets — alongside a new global usage statistics page (with time-range filters), a hierarchical session trace redesign, a ShellGuard verdict log page, session pause/resume, and byte-level loading progress
  • Helix-agent: Prefix-cache stability across restarts is hardened (tool list and skill/memory snapshots now persist across restarts; worktree binding fixed), sub-agent double-runs and sub-session ID collisions are fixed, background tasks are exempt from timeouts with incremental job_wait harvesting, and the global usage statistics API (with time-range filtering) is available

Helix Code​

  • New: Cross-platform design overhaul — a unified density system on desktop and mobile (three layout classes + dual density tokens), top-bar actions condensed to 3 persistent buttons + an overflow menu, a mobile bottom navigation with session actions in an overflow menu, touch hit targets increased to 44, and chat/settings/sidebar/file-tree spacing adapted per device
  • New: Global usage statistics page — machine-level token totals across sessions, filterable by today / yesterday / last 7 days / last 30 days / this month
  • New: Session trace page upgraded to a hierarchical work path with usage and duration gauges — expandable by turn → step → execution, including sub-agent details and a "this session + sub-agents" total
  • New: ShellGuard verdict log page — audit whether guard verdicts were correct, distinguishing "no verdict given" from "allowed"
  • New: Session pause/resume — a pause button and a paused banner; the button switches to "Continue" while paused
  • New: Byte-level download progress when loading sessions (visible progress and animation on slow or tunneled networks); the load timeout is now an idle timeout with an absolute cap that truly aborts the request
  • New: Thinking output collapses to a single-line summary in focused mode (click to expand in place); the chat header shows the session's execution machine
  • Improved: Chat runtime performance — removed high-frequency full-page rebuilds, duplicate in-build computation, and full-list polling write-backs
  • Improved: The session list supports "collapse" alongside "show more"; sidebar entry display state is now shared across views
  • Fix: Interjection waits are no longer falsely shown as "paused", and duplicated trailing messages are gone; the session loading indicator no longer disappears before a large session finishes loading
  • Fix: The log panel no longer yanks back to the bottom after scrolling up or disabling auto-scroll, and resumes following after agent start/stop rebuilds the list
  • Fix: Network route selection only uses "probe-reachable" endpoints — the first attempt uses the speed-tested route, and a failure immediately switches routes and retries

Helix-agent​

  • New: Prefix-cache stability across restarts — the tool list and skill/memory snapshots persist across restarts, fixing the prefix-cache breakage after restarts
  • New: Global usage statistics API (cross-session token aggregation) with time-range filtering (today / yesterday / last 7 days / last 30 days / this month)
  • Fix: Sub-agent double-runs — a sub-session no longer runs two concurrent executions, eliminating duplicated spend and distorted statistics; sub-session IDs are now unique, removing cross-parent collisions
  • New: Background-task turn limit unified at 200; background tasks are exempt from timeouts (long tasks are no longer killed)
  • Improved: job_wait incremental output + interjection interruption; under remote bindings job_wait can now harvest sub-agent tasks
  • Fix: Image handling — tool-result images are side-placed as user messages (images from tools such as read_image are visible to the model); oversized outbound images are auto-resized and image-related 400s are strip-and-retried
  • Fix: MCP tool enumeration timeout raised from 2s to 6s; MCP port allocation now holds the binding and switches ports automatically on conflict (no more silent breakage)
  • New: ShellGuard verdict query API with verdicts and usage recorded to traces; fixed the case where an upstream tool_choice rejection disabled the guard entirely
  • Fix: After a restart, a session stays stopped until the user resumes it; done/error broadcasts carry the authoritative queue count
  • Improved: The session messages endpoint returns an X-Total-Bytes header for client-side download progress alignment

v1.5.32 · 2026-09-09​

Summary​

  • Helix Code: Fixed the left project/machine list reshuffling when clicking sessions on another machine — session switching stays stable
  • Helix-agent: MCP tool enumeration failures now reuse the last successful list, and MEMORY.md injection is now a session-level snapshot — both changes keep the prompt prefix stable so prefix caching is no longer broken

Helix Code​

  • Fix: Clicking sessions on another machine in the left project/machine list no longer reshuffles or jumps the list based on activity time

Helix-agent​

  • Fix: When MCP tool enumeration fails, the last successful list is reused — the prompt prefix is no longer rewritten and prefix caching is preserved
  • Fix: MEMORY.md injection is now a session-level snapshot — writing memory inside a session no longer breaks prompt prefix caching

v1.5.31 · 2026-09-08​

Summary​

  • Helix Code: The editor now embeds inline preview for image files and inline playback for video files (the backend download endpoint supports Range passthrough so video seeking works); the left project/machine list is now manually reorderable by drag (clicking sessions on another machine no longer reshuffles the list); fixed the copy button on desktop layouts accidentally triggering the right-side session navigation rail
  • Helix-agent: The download endpoint supports Range passthrough and real MIME types (for editor video preview seeking); workspace-level context cache and auto-compress settings now persist across restarts instead of falling back to defaults

Helix Code​

  • New: Editor supports inline image preview — image files are previewed directly in the editor without downloading
  • New: Editor supports inline video playback — video files play directly in the editor with a seekable progress bar (powered by backend Range passthrough)
  • Improved: The left project/machine list is now manually reorderable by drag — clicking a session on another machine no longer reshuffles or jumps the list based on activity time; the order is user-controlled
  • Fix: Desktop layout reserves a lane for the right-side session navigation rail — message action buttons (e.g. copy) no longer overlap its hover hit zone and misfire

Helix-agent​

  • New: The download endpoint supports Range passthrough and real MIME types — video preview can seek, and responses carry correct content types (including the lightagent remote side)
  • Fix: Workspace-level context cache settings persist across restarts instead of falling back to defaults
  • Fix: Workspace-level auto-compress settings persist across restarts instead of falling back to defaults

v1.5.30 · 2026-09-05​

Summary​

  • Helix Code: Session trace usage display enhanced — token counts use professional k/M/B formatting, each request's input/output/cache-hit ratio shows in a single line, and trace content supports select-to-copy; fixed the chat list being forcibly yanked back to the bottom when scrolling up, ask_user pending-choice card loading issues, and a lingering "message queued" hint after interjection consumption
  • Helix-agent: No new code changes in this release (binaries rebuilt for the release)

Helix Code​

  • New: Session trace usage display enhanced — token counts use professional k/M/B formatting (220W → 2.2M, 999999 normalizes to 1.0M), step/end rows show each request's input/output/cache-hit ratio in a single line on the right, the hit ratio appears only when caching actually occurred, and trace content supports select-to-copy
  • Fix: Scrolling up in the chat list is no longer forcibly yanked back to the bottom (removed the auto-scroll-back loop)
  • Fix: ask_user pending-choice cards no longer show a red alert or missing options
  • Fix: The "message queued" hint no longer lingers after an interjection is consumed (no false queue hint when there is no composer)

v1.5.29 · 2026-09-03​

Summary​

  • Helix Code: New session "execution machine" picker reads the latest binding snapshot (newly bound machines are immediately available), BYOK context-cache discard trigger percentage is configurable, session token usage and cache hit ratio are displayed, and workspace-level context cache defaults are configurable (applies globally per machine)
  • Helix-agent: Workspace-level context cache configuration, BYOK cache discard percentage exposure + token usage hit tracking, session trace head/tail fixes, remote lightagent background tasks visible, grok-style <thinking> tag stripping, non-UTF-8 text file preview, Studio agent export excludes runtime files

Helix Code​

  • Fix: New session "execution machine" picker reads the latest binding snapshot — newly bound machines appear in the picker immediately without waiting for the next session
  • New: BYOK context-cache discard trigger percentage setting — the cache discard threshold is configurable in Settings (50%–100%, default 70%); when set above the compression percentage, discard is not triggered
  • New: Session token usage and cache hit ratio display — the session trace page shows cached tokens, reasoning tokens, and hit ratio
  • New: Workspace-level context cache default configuration — applies globally per machine and is applied to new sessions automatically

Helix-agent​

  • New: Workspace-level context cache configuration — applies globally per machine; when a session manually overrides part of the settings, the remaining workspace fields are preserved
  • New: BYOK cache discard percentage (token_threshold_percent exposed) + token usage hit tracking (step/end now include cached/reasoning/hit_ratio; new /sessions/:sid/usage aggregation endpoint)
  • Fix: Session trace head/tail fixes — turn counting resumes after process restart, interrupted turns are closed correctly, and sub-agent head/tail turns are filled in
  • Improve: Background tasks of remote lightagent-bound sessions are visible in the AgentUI panel
  • Fix: Strip <thinking> XML tags from grok-style model output so they no longer pollute chat content
  • Fix: Non-UTF-8 (GBK/UTF-16) text files preview correctly by trusting known text extensions
  • Fix: Studio agent export/import excludes runtime files (.dream-last-at / .dream-lock / .DS_Store)

v1.5.28 · 2026-08-30​

Summary​

  • Helix Code: Chat tool names are now fully bilingual — the memory tool family (list/read/write/append) and local_file_read no longer fall back to English humanize; the Chinese UI shows Chinese tool names throughout
  • Helix-agent: No new code changes in this release (binaries rebuilt for the release)

Helix Code​

  • Improve: Memory tool family names are displayed bilingually — memory_append / memory_read / memory_write / memory_list now render in the UI language in focused summaries (e.g., 'Append to memory' / '追加记忆')
  • Improve: local_file_read tool name is displayed bilingually — the local read-only file channel renders in the UI language ('Read local file' / '读取本地文件')
  • Improve: Added bilingual regression assertions for all 4 memory tool keys so future spelling mistakes cannot slip through unnoticed

v1.5.27 · 2026-08-30​

Summary​

  • Helix Code: Machine online probes stay online during credential outages (selfhost side no longer falsely reports offline when credential fetches time out), session navigation list filters out completed background-task records, job_wait tool name is bilingual with unified icon, old session groups no longer collapse abruptly when switching workspaces
  • Helix-agent: Workspace file downloads are correctly forwarded under remote lightagent bindings (no more 404), easyagent tunnel session token auto-renews

Helix Code​

  • Fix: Machine online probes stay online during credential outages — credential fetches get a 5-second timeout with 5-second failure backoff, in-flight fetches are deduplicated, and node credentials are cached, so node-verified probes no longer falsely report offline while credentials are temporarily unavailable
  • Fix: Session navigation list filters out completed background-task records — finished background tasks no longer appear as session records in the navigation list
  • Improve: job_wait tool name is now displayed bilingually (zh/en), with an icon unified with the background-task family
  • Fix: Old session groups no longer collapse abruptly after switching the current workspace (didUpdateWidget now has a switch guard)

Helix-agent​

  • Fix: Workspace file downloads are correctly forwarded under remote lightagent bindings — DownloadWorkspace no longer resolves remote paths locally and 404s; it now forwards to the remote /api/fs/download (err-first 502, path joining guards against Windows backslashes)
  • Fix: easyagent tunnel session token auto-renews — tokens are refreshed automatically after expiry, so tunnels no longer break on expired tokens

v1.5.26 · 2026-08-22​

Summary​

  • Helix Code: Streaming message rendering optimized (sub-sessions only redraw the last message, embedded session details no longer flicker), scroll-to-bottom button shows on demand, helix-vmd local VM improvements (auto-start all registered VMs on boot, concurrent downloads, automatic QEMU discovery)
  • Helix-agent: OpenAI-compatible vision image budget (prep for DeepSeek multimodal), session runtime processing persistence fixes (no stale running state on disk, terminal receipt persisted after API failure)

Helix Code​

  • Improve: Streaming message rendering — streamed text only updates the last message; sub-sessions (sub_agent_*) and separate view windows share the local redraw path, eliminating whole-list rebuilds and flicker in embedded session details
  • Improve: Scroll-to-bottom button shows only when not at the bottom
  • Improve: helix-vmd auto-starts all registered VMs when the daemon boots, drains all VMs on shutdown, reaps orphan QEMU processes, and keeps a per-VM stderr log
  • Improve: Local VM adds automatic QEMU discovery (including the Windows registry), concurrent template downloads with resume, plus timeout and retry on download failures
  • Fix: Background task details stay open when session metadata updates while work is running (no longer treated as a navigation event)

Helix-agent​

  • New: OpenAI-compatible vision image budget — at most 4 images per message, trimming oldest-first over-limit images and replacing oversized ones by byte budget, preparing for DeepSeek multimodal models
  • Fix: Session runtime processing state is no longer written to disk — persisted sessions never carry a stale running state (continuations are restored from PendingMessages after restart)
  • Fix: API request failures now correctly clear the runtime processing flag and persist a terminal receipt, so runtime and terminal status cannot diverge

v1.5.25 · 2026-08-18​

Summary​

  • Helix Code: Mobile session list now supports multi-machine grouped summary (same as desktop), agent task cards have stable height (message list no longer jumps), and Markdown display repair (display-only fixes for damaged formatting, original text unchanged)

Helix Code​

  • New: Markdown display repair — fixes damaged formatting in completed replies such as table separator rows merged with data rows and unclosed trailing inline delimiters; display-only, original text is never modified, and a repair indicator appears in the message action row when fixed
  • Improve: Mobile session list multi-machine grouping — the drawer now enters a multi-workspace (multi-machine) view consistent with desktop
  • Fix: Residual display cleanup after interjection completes (idempotent session state sync fallback)
  • Fix: Agent task progress cards have stable height — collapse/expand no longer causes the message list to jump

v1.5.24 · 2026-08-16​

Summary​

  • Helix Code: Add session trace timeline view with message timestamp display, Goal mode UI (/ command entry + goal card), workspace multi-execution bindings (local + multiple remote machines), and web-search option with progress display

  • Helix Code adds full image support: drag-and-drop upload, lightbox preview, and tool-result image rendering. Thinking-mode button redesigned, stream flicker fixed, and history pre-load sped up.
  • Helix-agent adds image support in tool results across all providers and passes images through sub-agent pipelines; fixes multiple longterm-chat data-loss bugs and adds SSH keepalive timeout protection for Remote MCP.

Helix Code​

  • Added drag-and-drop image upload from Finder / Explorer directly into the chat input area.
  • Tool result message cards now render images returned by tools.
  • Added lightbox tap-to-expand preview for images in the chat.
  • Redesigned thinking-mode button as a capsule with clearer visual weight; balanced-mode icon and label improved.
  • Added bilingual (zh/en) i18n support for effort-level labels in the chat page.
  • Fixed stream-end full-refresh causing visible flicker after a response completes.
  • Fixed three bugs where switching models after creating a new session had no effect.
  • Fixed sub-agent interruptions incorrectly inheriting the manager's model / thinking / effort parameters.
  • Fixed macOS file picker silently failing in multi-window mode.
  • Fixed manager cold-start not pre-seating currentSession, causing AgentSelectorHeader to be invisible on launch.
  • Fixed {name} placeholder not being replaced in the workspace-connecting dialog.
  • Fixed account balance incorrectly showing "Unlimited" when the balance was negative.
  • Increased background history pre-load limit to 5 000 to reduce incremental prepend batches and scroll jitter.

Helix-agent​

  • Added image support for tool results: all providers now forward image data, and results are pushed to the frontend via WebSocket.
  • Images are now passed through longterm_chat and run_subagent pipelines to sub-agents.
  • Fixed two longterm-chat data-loss bugs: cancel-propagation incorrectly dropped interject-queue messages; a race window caused saves to be skipped when a session was stopping.
  • Fixed manager cancel not propagating to running sub-agents, leaving orphaned goroutines.
  • Fixed UpdateMCPConfigWithServers rebuilding the runner without restoring message history, overwriting disk history on restart.
  • Fixed API-mode interject truncating an active sub-agent task execution flow.
  • Fixed CLI-mode interject messages being silently dropped.
  • Prevented mid-loop model switching during Phase 2/3 tool cycles to avoid history truncation and persistence loss.
  • Removed sub-agent code-review guidance from coderSystemPrompt to reduce unnecessary nested agent calls.
  • Added SSH keepalive timeout protection for Remote MCP to prevent infinite hangs on dropped connections.

v1.0.18 · 2026-03-16​

Summary​

  • Helix Code overhauls the full tunnel URL pipeline so all connections use live, up-to-date tunnel addresses; adds new branding assets, scroll-to-top button, and multi-line log copy.
  • Helix-agent fixes background task routing races, prevents 0-byte session files on crash, and adds lanproxycore auto re-enrollment on authentication failure.

Helix Code​

  • Overhauled the full tunnel URL pipeline: ApiService, WebSocket, workspace connection, and credential binding now all use the live tunnel URL from the cloud, fixing cross-device 401 errors and stale-port issues.
  • Tunnel connection info is now stored and synced to cloud; soft-deleted devices can be recovered during sync.
  • Server selector now displays tunnel URL instead of direct IP; tunnel status refreshes in the background with proper concurrency safety.
  • Tunnel URL is no longer statically cached — the latest port is fetched from cloud before connecting and after sync.
  • Fixed connectWorkspace to match synced entries by nodeId, preventing cross-device tunnel URL pollution.
  • Fixed multi-device conflict where the same serverUrl across multiple devices overwrote each other; now keyed by nodeId:serverUrl.
  • Local 127.0.0.1 services always use direct connection and never route through tunnel.
  • Fixed macOS orphaned backend process on window close; ensures proper NSApp.terminate() on last window close.
  • Fixed a Swift API rename error (replyToApplicationShouldTerminate).
  • Replaced all platform icons with the new transparent Helix logo.
  • Added scroll-to-top button and hides scrollbar during streaming for a cleaner chat experience.
  • Restored auto-scroll broken by a previous streaming optimization.
  • Optimized sub-dialog window rendering to streaming-only mode for better performance.
  • Fixed session list debounced sort, scroll freeze, and animated reorder.
  • Log panel now supports multi-line selection and copy.
  • Fixed Shift/Cmd/Ctrl+Enter inserting line break in Enter-to-send mode; IME composing now prevents accidental message send.
  • Added backward compatibility for HTTP 404 on cloud device management for legacy backends.

Helix-agent​

  • Fixed ClearedMarkerJSON to emit valid JSON with defensive json.Valid guard.
  • Fixed background task routing and session rendering issues.
