ChunkHound

# Changelog All notable changes to ChunkHound will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Breaking Changes - **HTTP MCP server removed** - ChunkHound now supports stdio transport only for MCP connections - `chunkhound mcp http` command removed - `--http`, `--port`, `--host` CLI flags removed - FastMCP dependency removed - Migration: Use `chunkhound mcp` (stdio) instead. All major MCP clients (Claude Code, Claude Desktop, VS Code) support stdio transport. - Rationale: Simplified codebase, reduced dependencies, focused on primary use case (stdio is the standard for MCP) ### Added - OpenAI Responses API support for reasoning models (gpt-5.1, gpt-5.1-codex, o-series, gpt-5-pro) - enables deep code research with enhanced reasoning capabilities - Automatic API routing between Chat Completions and Responses API based on model compatibility - supports 30+ models including all GPT-5, GPT-4.1, GPT-4o, and o-series models - Reasoning effort control for deep research LLM operations - configurable levels (none, minimal, low, medium, high) via `CHUNKHOUND_LLM_CODEX_REASONING_EFFORT` with per-role overrides for utility and synthesis operations - Structured JSON output support for Responses API - maintains schema validation consistency across both Chat Completions and Responses endpoints ### Performance - LanceDB table creation now detects embedding dimensions upfront from configured embedding provider, eliminating O(n) table recreation penalty during first embedding insertion - significantly improves indexing performance for large codebases (e.g., 16,000+ chunks no longer require full table migration) ### Fixed - Global chunk deduplication now applies to all parsers (YAML, Universal) - prevents duplicate chunk IDs that caused indexing failures with repeated config values ## [4.1.0b1] - 2025-11-15 ### Added - PHP configuration files with top-level return arrays are now searchable - config patterns like `return ['key' => 'value'];` are automatically indexed - Universal config-literal parsing across Python, JavaScript, TypeScript, and JSX/TSX - all exported configuration objects and arrays are now discoverable through semantic search ### Enhanced - Windows compatibility improved with cross-platform temporary directory handling for Claude Code CLI provider - JavaScript-family parsers (JavaScript, TypeScript, JSX/TSX) internally streamlined to reduce maintenance overhead while preserving all functionality - Version management now supports PEP 440 pre-release formats (beta, release candidate) for clearer update channels - Version tagging includes safety checks to prevent accidental releases from uncommitted work ### Fixed - Code quality improvements addressing linting warnings for cleaner, more maintainable codebase ## [4.0.1] - 2025-11-12 ### Fixed - Package build configuration now excludes test fixtures from distribution, reducing package size and removing unnecessary test data from published releases ## [4.0.0] - 2025-11-12 ### Added -
