v0.15.0

Features

• "Extract interface from class" refactor action: Generates an interface from a class's public non-constructor methods and inserts it above the class declaration, appending implements Name to the class header. Handles existing implements lists, static methods, union/nullable return types, and unbraced namespaces.
• "Add missing @throws tags" refactor action: Offers to add @throws tags to a docblock for throw new ClassName() sites not yet documented, for both a single missing tag and multiple.
• "Update PHPDoc to match signature" refactor action: Regenerates an out-of-sync @param/@return block from the actual signature, preserving descriptions, @throws, and @see tags.
• "Convert local variable to instance property" refactor action.
• "Convert switch to match" refactor action: Offered when every non-empty case body is a single return; requires a default arm to preserve the exhaustiveness contract. Fall-through cases are grouped into comma-separated arms and dead break; is stripped.
• "Convert to closure" refactor action: Inverse of "Convert to arrow function" — converts fn($p): T => expr to function($p): T { return expr; }, handling static, by-ref returns, and nested arrow functions.
• "Convert to arrow function" refactor action: Converts an eligible closure (single-statement return, no by-ref use, no yield) to a PHP 7.4 arrow function.
• "Change visibility" refactor action: Offers "Make public / protected / private" on a method, property, or class-constant declaration line.
• @method parameter lists in signature help: @method tag signatures from docblocks are now used as a fallback source of parameter info when no real method body is found.
• Docblock descriptions in signature help: The free-text description preceding a function/method's docblock tags is now shown in SignatureInformation.documentation.
• Workspace scan progress percentage: $/progress now reports WorkDoneProgressReport with a percentage after each 500-file chunk, so editors can show a live progress bar during workspace scan.
• cachePath initialization option: Pins the on-disk cache to an explicit directory without touching XDG_CACHE_HOME.

Performance

• Dependent-diagnostics sweep is cancellable: When a file that others depend on is edited, the workspace-wide re-analysis of its dependents now runs under a cancel token that the next edit flips. A newer keystroke preempts an in-flight sweep at the next file boundary instead of letting it run to completion, so typing over a widely-depended-on base class, interface, or trait stays responsive; superseded sweeps also drop their partial results so they can't land out of order.
• Document highlight stays responsive under write pressure: textDocument/documentHighlight now reads through a stale-tolerant accessor that serves the last-good cached parse instead of joining the cancellation retry loop when a concurrent edit stream keeps invalidating the snapshot.
• Cache eviction gains LRU shedding: parsed_cache, analysis_cache, owned_program_cache, and type_map_cache share recency tracking with bounded caps; the least-recently-used half is shed on overflow instead of an arbitrary front slice, so actively edited files survive a references sweep over a large candidate set.
• Find-references prunes by owner reachability earlier: The owner-class reachability check now runs before per-candidate analysis instead of as a post-filter, skipping expensive analysis on files that only text-match the method name. Cold references are 1.4×–3.2× faster across 100–3 000 files.
• code_lens and workspace/diagnostic cancel on concurrent write: Both handlers now poll a write-revision counter and abandon a stale scan instead of computing results that would be discarded.
• Completion, hover, inlay-hint, and workspace-symbol CPU work offloaded: These handlers now run on spawn_blocking instead of the async executor, so a slow request no longer stalls unrelated requests on the same worker thread. References also cancel on a concurrent write.

Fixed

• Completion suggests unimported classes from unopened files: Class-name completion now searches a workspace-index-backed table in addition to open documents, so a class defined in a file never opened in the editor (a sibling package, or vendor/ when indexVendor is enabled) appears as a candidate and triggers auto-import (#240).
• Cache correctness on size-preserving edits: The on-disk cache key switched from mtime + size to blake3(uri || content), so a size-preserving edit within the same mtime second is no longer missed.
• Silent panics in call hierarchy and code lens now logged: incoming_calls, outgoing_calls, and code_lens now emit tracing::warn! with the target URI when their spawn_blocking task panics, instead of silently returning an empty result.
• vendor_index_cache no longer grows unbounded: Moved into the shared CacheRegistry so it is evicted alongside the other per-file caches instead of only ever being inserted into.

Dependencies

• mir updated to 0.50.2, salsa to 0.27.2. 0.50.2 fixes a concurrent-read salsa query-stack abort (index_generation read the shared db handle) that could SIGABRT under simultaneous indexing and reference queries.
