Released July 26, 2026 · Full changelog
v7.2.0 broadens model steering, hardens long-running sessions, and adds a native AX Wiki compiler — alongside substantial stability, dependency-security, and Desktop polish work.
Highlights
- Effort levels across providers — Anthropic, OpenAI, xAI, and CLI providers now
expose configurable effort levels.
Autoselects a balanced baseline and is preserved across retries, model switches, and session restore, and workflow effort is wired through to reasoning-depth policy. - Grok 4.5 is now the curated xAI flagship model.
- Super-long runs get a pacing grace window,
rateLimitTierwiring, and run-engagement visibility, so long-running goals stay engaged instead of stalling. /looprecurring prompts and conversational scheduled tasks let you automate repeat work directly from a session.- Native AX Wiki compiler replaces the external dependency.
- Code intelligence gains a tree-sitter syntactic fallback, graph highlights, and openwiki interop — and no longer indexes your home directory.
New features
feat(ax-engine): MTP Auto runtime with Direct fallback and a Homebrew install path.feat(desktop): inline retry for failed assistant turns; secondary-view back bar,focus_chatshortcut, and auto-collapsing left sidebar.feat(provider): effort levels for Anthropic/OpenAI with a polished/effortUX; Grok 4.5 added as the xAI flagship.feat(ux): model variants presented as effort levels.feat: workflow effort wired to reasoning-depth policy.
Improvements
refactor: improved error observability, SSE backpressure handling, and type safety across the server.refactor(desktop): converged font sizes onto semantic typography classes and removed the disabled feature tour.refactor(tui): renamed the built-inopencodetheme toclassic.- Desktop onboarding now shows platform-native CLI install commands; Windows/macOS install and enterprise/winget UX improved; Windows install verified with minisign.
Fixes
- Sessions: long-run step ceiling with convergence warning and pause-at-limit; goal ceiling preserved through budget wrap-up; avoided 1-step agent livelock under infinite continuation caps; stopped repeated truncated-output retries; cut prompt-loop DB reloads.
- Concurrency: added outbound concurrency caps and coalesced stream part writes; fixed a permit-transfer open-slot race (now covered by a regression test).
- Code intelligence / LSP: stopped indexing the home directory and purged legacy home graphs; capped connected LSP clients per server with LRU eviction.
- TUI: pinned
node:ffipointer sources against V8 GC during native calls; resolved the backend loader from the startup working directory. - Formatting: prevented duration and compact-unit formatters from emitting overflow
units (e.g.
60m/24hremainders) for scheduled tasks and durations. - Desktop: 15 fixes across the Electron shell, UI stores/sync, and web server, plus chat empty-state, toast, motion-a11y, ConfirmDialog migration, tab-persistence, and effort-on-retry fixes.
- Dependencies: resolved 12 of 13 open advisories via scoped overrides; patched freshly
published
protobufjsandtaradvisories; bumpedadm-zip(GHSA-xcpc-8h2w-3j85). - Plus stability, release-safety, display-formatting, and path-label hardening from several code-review passes.
Deprecations and removals
- Removed the native Ratatui TUI mode. The SolidJS terminal TUI and the Desktop app are the supported surfaces going forward.
