v1.6.0

What's New

Performance: Parser & Query Caching

• Thread-local parser cache — parse_string() now reuses parsers across calls for the same language, avoiding the cost of creating a new parser every time
• Two-level compiled query cache — run_query() caches compiled tree-sitter queries in both a thread-local cache (fast, no locking) and a global shared cache (cross-thread reuse)
• Cached parsers in extraction & intelligence — CompiledExtraction::extract() and intel::parse_source() now use the thread-local parser cache
• Pre-computed capture names in CompiledExtraction — avoids rebuilding capture name vectors on every extraction call
• QueryCursor reuse across patterns within a single extract_from_tree() call

Bug Fixes

• compiled_query() now propagates Error::LockPoisoned instead of silently ignoring poisoned RwLock
• QueryCursor byte-range no longer leaks between patterns when reusing the cursor in extract_from_tree()
• Replaced std::collections::HashMap with ahash::AHashMap in parser cache for consistency
• Redundant get_language() call removed from parse_string() hot path — only called on cache miss
• Fixed stale crate-local language_definitions.json (frozen at 248 languages) causing missing extension mappings for 58 newer languages
• Resolved 4 duplicate extension conflicts: .gd (gap/gdscript), .conf (hocon/nginx), .sv/.svh (verilog/systemverilog)
• build.rs now prefers sources/language_definitions.json over the crate-local copy to prevent future staleness

Go Symbol Extraction

• Go type_spec declarations (structs, interfaces, type aliases) are now extracted as symbols with correct SymbolKind

Documentation

• New dedicated "Download Parsers" section in the quickstart guide covering:
  • CLI, Python, Node.js, and Rust download APIs
  • Language groups (web, systems, scripting, data, jvm, functional)
  • Docker and CI pre-download examples
  • Configuration file (language-pack.toml) setup
  • Cache location and override options
