- Replaced external JSON/JSONL parsing libraries with Bun's built-in JSON5 and JSONL APIs across all packages.
- Removed dependencies: json5, ndjson, get-east-asian-width, json-stringify-safe, split2, through2, and @types/ndjson.
- Replaced custom text width and ANSI wrapping implementations with Bun.stringWidth() and Bun.wrapAnsi() APIs.
- Updated Bun type definitions from ^1.2.17 to ^1.2.18 and bun-types from ^1.3.5 to ^1.3.7.
- Refactored JSONL parsing throughout codebase to use Bun.JSONL.parse() and Bun.JSONL.parseChunk() with improved buffer management and error handling.
- Updated test assertions to use Bun.stringWidth() for dynamic width calculations instead of hardcoded values.
- Fixed autocomplete race condition in editor by tracking request ID to discard stale results.
- Added guard clause in plugin-settings to prevent null reference when settings list is undefined.
- Added branch change callbacks in footer to update state after git head resolution.
- Added timing instrumentation to Python kernel startup and gateway acquisition.
- Improved error logging in settings manager for config file access failures.
- Fixed model discovery to re-check file existence after JSON to YAML migration and improved file access error handling.
- Converted readdirSync, readFileSync, and statSync to async readdir, readFile, stat across skills and agent discovery.
- Made scanDirectoryForSkills async and refactored custom directory scanning to use Promise.all for concurrent processing.
- Updated agent discovery to use fs/promises for async file reading and refactored helper patterns.
- Added AgentParsingError exception class for better error handling during agent parsing.
- Added filesystem error type guards (isEnoent, isEacces, isPerm, etc.) to pi-utils for safe error checking.
- Added color manipulation utilities to pi-utils for accessibility features.
- Added color-blind mode setting to settings manager.
- Migrated plugins, settings, and config modules from sync to async file operations.
- Updated error handling to use new pi-utils type guards for type-safe checking.
- Enhanced patch applicator with fallback variant generation and improved fuzzy matching.
- Added support for ellipsis placeholders, top-of-file anchors, and comment-prefix normalization.
- Renamed operation and moveTo parameters to op and rename across patch tool interfaces.
- Added batch processing system to benchmark runner for parallel task execution.
- Added comprehensive benchmark reports for Claude Haiku and GPT-5.1-codex-mini models.
- Added allowFuzzy option to control fuzzy matching behavior in patch operations.
- Added validation for line numbers to ensure they are >= 1 in patch headers and hints.
- Enhanced fuzzy matching algorithms to respect the allowFuzzy setting for precise control.
- Fixed patch application to prefer actual diff over cached preview when displaying results.
