Reasonix changelog: what's new each month

Every stable Reasonix release summarised by month: the highlights, new features, improvements, fixes and anything you need to act on. 3 months covered; the current month updates daily.

October 2026 · so far

9 releases: 1.39.6 → 2.30.0

October brought stability improvements and better error handling to Reasonix, along with enhancements to session management and user-facing error messages. New features focused on visual output, skill filtering, and improved form handling.

Highlights

  • Sessions now preserve usage statistics when switching between them, no longer resetting request counts and token usage.
  • Models can now render charts directly in conversations using renderchart, displayed as tables in terminal mode.
  • Service provider forms gained unsaved change warnings, detailed connection diagnostics, and a fixed save bar with keyboard shortcut support.
  • Completed but unviewed sessions now display a marker that persists across restarts until opened.
  • Error messages now show specific reasons for failures like history import problems and session loading issues, with links to relevant settings.

New

  • Sidebar toggle to stop connecting to remote machines and hide them from the project list.
  • Theme packs can now customize link colors, brand color, hover glow, and agent name colors independently.
  • Resume command in terminal UI lets users continue a saved session directly by number with /resume <n>.
  • Skills can declare file paths matching via paths: to appear in model skill lists only after sessions encounter matching files.
  • Edit goal feature now uses an in-application form to modify objectives and maximum rounds with validation.
  • Service provider forms display test results next to buttons and show a summary row with a dedicated button to test all enabled models.
  • Mobile web interface can now view read-only browser tabs that the agent is currently using.
  • Settings search now matches display names in the current interface language, allowing multilingual searches.

Improved

  • Idle connection failures between conversation turns no longer cause unexpected EOF errors; retry logic now only applies when no response bytes were received.
  • Interruption recovery prompts now clearly state that new messages take priority and old tasks should not be resumed if unrelated.
  • Session history loading failures now display the specific technical reason in details, improving troubleshooting.
  • History import failures categorize errors (workspace conflict, oversized/corrupted history, unsupported version, occupied source) and provide a link to view recovery details in storage settings.
  • Long conversation turns split across pagination pages can now be collapsed, and scrolling to the bottom auto-loads the next page.
  • Compression timeout changed to wait indefinitely while content is still being returned; 30-minute total limit remains.
  • Model request retries now display the specific reason (dropped connection, timeout, server status code, stream stalling) and wait time in the status line.
  • Default model setting now displays the configured default instead of changing with the current session's model selection.

Fixed

  • Upgrade from 1.38 no longer leaves persistent configuration warnings about project permissions and Windows folder path variations.
  • Sidebar manual sort order now properly resets when switching to time-based sorting via new reset option that preserves grouping.
  • Desktop application now releases robot bridging and usage tracking threads on shutdown instead of accumulating them.
  • PowerShell encoding errors no longer appear before shell command output on Windows in constrained language mode or without console.
  • Session forking from the same parent no longer causes workspace history load failures due to duplicate source registration.
  • Switching between remote sessions while busy no longer loses queued messages or attachment data.

September 2026

34 releases: 1.36.0 → 1.39.5

September brought major architectural improvements to Reasonix, including a simplified agent core, new session persistence with support for larger conversations, and numerous reliability fixes across desktop and remote workflows. The month focused on session management, collaborative features, and stability across platforms.

Action needed
  • Agent core now runs executor-only by default; planner, continuation, and compaction require explicit enablement.
  • Session storage migrated to v4 format with append-only DAG log; large sessions now supported without previous limits.
  • Project MCP services require approval before first use, with re-approval on configuration changes.
  • Permission rules must use tool references like Bash(...) instead of bare commands; bare commands are no longer accepted.

Highlights

  • Collaborative session takeover between desktop and CLI with shared ownership and recovery capabilities.
  • Simplified agent core that runs executor-only by default, with planner and continuation explicitly enabled.
  • New append-only session storage format (v4) supporting large sessions without the previous 128 MiB replay limit.
  • Electron-based desktop shell replacing Wails, improving window management and stability.
  • Enhanced session recovery for blocked conversations with invalid tool parameters or missing images.

New

  • Sticky context file pinning to preserve workspace files through context compression.
  • Independent web search running parallel to main conversation with separate recovery budget.
  • Unified management pages for settings, trash, and automation with shared navigation.
  • ModelScope provider preset with seven curated models including Qwen and DeepSeek.
  • Persistent tool recovery allowing interrupted executions to be resumed with evidence support.
  • Unified Ask and decision dialogs with compact controls, per-question pagination, and draft recovery.
  • Context panel showing real-time elapsed duration during long tool executions.
  • Project configuration security requiring approval for MCP services and preventing setting loosening.

Improved

  • Session scrolling stability with reduced animation overlap and proper range updates.
  • Model capability detection now driven by model-level metadata instead of manual lists.
  • Admin commands like /compact and /context no longer require creating agent turns.
  • Session renderer replaced with full DOM/windowed renderer for better performance and scrolling.
  • Provider recovery with timeouts preventing infinite waits and clearer error messages.
  • Parallel tool cancellation bounded with grace period, preventing turns from hanging on lagging tools.
  • Session history loads immediately when switching tabs without waiting for runtime startup.
  • Model selector redesigned with provider filtering, favorites, and full catalog search.

Fixed

  • Ask prompt loops prevented by parsing missing local turn IDs from authoritative state before responding.
  • Long file reads now use dynamic budget and block changes until all incomplete reads resolved.
  • Desktop session state race conditions fixed where sessions appeared empty during transcript or runtime activity.
  • Duplicate messages in session history no longer prevent opening or archiving sessions.
  • Sessions no longer appear as ghosts in sidebar after permanent deletion from archive.
  • Session titles remain compact with full name shown on hover, preventing truncation issues.

August 2026

10 releases: 1.32.0 → 1.35.0

August brought major improvements to remote session handling, tool interaction simplification, and desktop stability. The month focused on making remote SSH workspaces more reliable, removing unnecessary tool patterns, and fixing several UI and session management issues.

Action needed
  • The finish tool mode has been removed from the provider interface; conversations now end naturally when complete.
  • Removed forced finish execution and protocol repair prompts; ask and data-carrying terminators like submitplan remain.

Highlights

  • Remote SSH workspaces now support precise session recovery and allow busy rounds to continue in the background when switching sessions.
  • Removed the forced finish tool pattern, allowing conversations to end naturally when the provider completes a visible response.
  • Session round events now persist across interruptions and restarts, preventing accepted side effects from running twice.
  • Desktop UI improvements stabilized conversation scrolling, task switching, and session index rebuilding.
  • Cross-platform shell support now safely handles Bash, zsh, and POSIX sh on macOS with deterministic Git discovery.

New

  • Remote SSH workspace support with session recovery and background round execution.
  • Adjustable notification volume slider (0–100%) with consistent loudness normalization for all notification sounds.
  • Explicit arrow dropdown menu for SSH host suggestions showing all saved connections with non-22 ports.
  • Safe remote credential proxy routing using scoped virtual tokens while desktop holds real provider credentials.
  • Persistent, ordered round events that survive interruptions and prevent side effect duplication.
  • Automatic panel collapse after completing todo items with fade-out behavior.
  • Sub-agent configuration profiles and task/tool contract documentation.

Improved

  • Conversation scrolling and navigation is now smoother with stabilized scroll surface ownership.
  • Tool schema reduced from approximately 4,298 tokens to 4,138 tokens.
  • Session index rebuilding is now bounded and awaitable; sidebar no longer stays stuck in rebuilding state.
  • Shell manifest now uses process-level caching for faster detection.
  • Task switching during execution no longer causes UI jitter.
  • Status polling failures during SSE frame races are now treated as benign snapshots instead of crashes.

Fixed

  • Protocol repair errors no longer appear to users when normal visible responses don't call finish.
  • Additional provider rounds no longer trigger when normal visible answers skip the finish tool.
  • Stale state races between SSE-derived frames and status polling no longer cause crashes.
  • Desktop now properly handles credential save, clear, or delete operations by syncing route rebuilds.
