ByteRover Changelog

​

Added

• Coding Agent hook integration - Support coding agents in querying/curating contexts from ByteRover via hooks (Claude Code only)
• PDF file reading - Curate contexts from PDF files with proper validation and magic byte detection
• Knowledge search tool - New search_knowledge tool for querying the context tree programmatically
• System sleep/wake detection - Improved reliability when user’s machines sleep and wake

​

Changed

• Increased curation concurrency - Curation tasks now run with concurrency of 3 (up from 1)
• Improved query search - Multi-perspective search strategy with few-shot examples and stop-word filtering
• Better curate responses - Curate agent now includes subtopic names in generated context
• REPL-first error messages - All error messages now reference REPL slash commands (e.g., /init instead of brv init)
• Updated documentation URL - Docs now point to production URL instead of beta

​

Fixed

• Binary file detection - Replaced byte-level heuristics with UTF-8 aware detection; fixes false positives for files with emojis, CJK text, and box-drawing characters
• PDF validation - Reject fake PDFs (binary files with .pdf extension) using magic byte validation
• Process reconnection - Fixed race conditions in agent restart and improved transport reconnection with exponential backoff
• Topic naming - Fixed _md suffix appearing in topic and sub-topic names during curation
• Pull sync filtering - README.md at context-tree root is now filtered during pull to avoid syncing incorrect files
• NPM security vulnerabilities - Updated dependencies to address security issues

​

Added

• Stateful sessions with auto-resume - sessions now persist and can be resumed after restart
• /new command to start a fresh session (clears conversation history while preserving context tree)
• Two-part context model for curation - contexts now include both raw concept and narrative sections

​

Changed

• /clear command renamed to /reset to avoid confusion with Unix clear command
• Upgraded default LLM to Gemini 3 Flash with thinking visualization support

​

Fixed

• File extension preserved correctly in knowledge relation paths
• Relation parser now handles file extensions and pattern matching more reliably
• Question marks removed from confirmation prompts for cleaner UI
• File paths now resolve correctly relative to project root (not working directory)
• Concurrent curation no longer gets stuck in queue state

• Randomized example prompts in welcome screen
• WSL (Windows Subsystem for Linux) support with file-based token storage fallback
• Read-file tool pagination and line truncation for handling large files

​

Changed

• Switched internal LLM service from gRPC to HTTP for improved reliability
• Sequential execution for brv curate commands to prevent conflicts

​

Fixed

• Security vulnerability in query string parsing
• Double @ prefix appearing in knowledge relations
• File validation when running brv curate from different directories
• Auth token validation now properly handles network errors
• SQLite database connection cleanup

​

Added

• Long-living agent with persistent task execution and restart support

​

Changed

• Updated onboarding UI with new visual design

​

Fixed

• /status command now correctly detects changes
• Agent restart during onboarding
• Path duplication in read_file tool
• Empty directory creation during curation

​

Fixed

• /status command now correctly displays CLI version

​

Changed

• Minimum Node.js version requirement increased from 18 to 20
• Simplified welcome banner by removing verbose onboarding instructions

​

Added

• Interactive REPL mode: Running brv with no arguments now starts an interactive terminal UI with a persistent session
• Slash commands: All core functionality is now available via slash commands in REPL mode:
  • /login, /logout - Authentication
  • /init - Project setup with team/space selection
  • /status - Show auth, config, and context tree state
  • /curate - Add context to context tree
  • /push [--branch <name>], /pull [--branch <name>] - Cloud sync (default branch: main)
  • /space list, /space switch - Space management
  • /gen-rules - Generate agent-specific rule files
  • /clear - Reset context tree
  • /query - Query context tree
• File references in curate: Use --files flag to include file references in autonomous curation
• Interactive onboarding: New guided onboarding flow for first-time users (press Esc to skip)

​

Changed

• Command renamed: reset command is now /clear in REPL mode

​

Fixed

• Improved UI responsiveness and layout
• Fixed terminal scrolling issues
• Fixed UI flickering during long-running operations
• Fixed tool error display showing ‘undefined’

​

Added
