DeepCode changelog: what's new each month
Every stable DeepCode 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.
September 2026
2 releases: 2.2.0 → 2.3.0
September brought major stability improvements to DeepCode's session handling, expanded the product across three interfaces, and added new security boundaries. The month featured both foundational reliability work and new user-facing capabilities like dictation and multi-provider support.
Highlights
- Sessions now preserve agent actions and state across reconnections, with on-demand compaction and proper context pressure measurement.
- DeepCode now runs as a single local service accessible through Desktop, Web, and CLI interfaces with shared model connections.
- Added dictation support for composing prompts via speech transcription in Desktop and Web clients.
- Memory injection now uses escaped boundaries to prevent prompt injection attacks from corrupted notes.
- Support for additional model providers including Opper and Amazon Bedrock, with accurate token window and pricing for DeepSeek V4.
New
- Dictation blocks in config enable speech-to-text transcription via Parakeet server or local parakeet-mlx.
- DeepCode Web interface connecting to the shared local background service.
- Sub-agents can delegate to Codex or Claude Code, with native follow-up conversations and lazy MCP server activation.
- Per-model declarations with live model discovery, context windows, and reasoning ladder configuration.
- Opper and Amazon Bedrock added to model provider templates.
- Opt-in egress control to limit which hosts receive prompts via providers.egress configuration.
- MEMORY.md can now be a short index with on-demand file reading, keeping memory deduplicated and within budget.
- Desktop app localized to Simplified Chinese with eight themes including high-contrast mode.
Improved
- Terminal interface now shows status line and tool cards, with selectors for bare commands and preserved prompt cache across turns.
- Session locking prevents multiple active writers from crashing each other when opening the same session in multiple windows.
- Model connections are now tested for streaming and tool call support before using custom services.
- Context pressure measured by actual usage reported by service providers rather than estimates.
- Desktop appearance scaling now properly resizes the entire application.
- Project switching no longer strands the MCP catalog.
- Drag-to-resize conversation edge, import VS Code color themes, and select from actually-installed fonts in Desktop.
- SQLite locking improved when multiple DeepCode processes share the state database.
Fixed
- Memory data boundary now catches every spelling variation of its closing tag.
- Native file operations routed through sandbox; Windows private files protected by fail-safe ACL.
- Command-executor bypasses closed and hardened.
- Plugin manifests now warn about plaintext credentials.
- Plugin manifests receive warnings about insecure patterns.
August 2026
2 releases: 2.0.0 → 2.1.0
August brought major improvements to task execution reliability and verification in DeepCode 2.0, followed by critical fixes and infrastructure updates in 2.1.
Highlights
- Tasks now complete end-to-end without getting stuck midway through execution.
- Code delivery is now verified through actual test runs, builds, and runtime checks.
- Automated workflows handle regression checks, test repairs, and repository maintenance without manual intervention.
- Detailed workflow errors now surface in the UI for better debugging.
New
- Loop Engineering for managing complex task execution
- Execution control throughout task workflows
- Verified delivery system that validates code through testing and builds
- Personalized Automation capabilities
- Unified CLI and Desktop experience
Improved
- Windows file access permissions restored to prevent broken builds
- Workflow error reporting now shows detailed information in the interface
- Backend route handling improved to prevent path traversal issues
Fixed
- Tasks no longer stop halfway through and require manual restarts
- Code verification now includes actual test execution and runtime validation
- LoopDetector and ProgressTracker imports corrected
- SPA catch-all route security vulnerability patched
July 2026
