Archived Changelogs

MCP graph tool for knowledge graph queries (parity with CLI yams graph).
Graph: snapshot-scoped version nodes, contains edges for file→symbol, --dead-code-report.
Graph prune policy (daemon.graph_prune) to keep latest snapshot versions.
Download CLI: progress streaming (human/json) via DownloadService callbacks.
Symbol-aware search ranking: definitions rank higher than usages (YAMS_SYMBOL_WEIGHT).
Zig language support: functions, structs, enums, unions, fields, imports, calls.

IPC latency reduced from ~8-28ms to ~2-5ms (connection pooling, async timers, cached config).
Post-ingest throughput: dedicated worker pool, adaptive backoff, batched directory ingests.

Compression stats now persist across daemon restarts (Storage Logical Bytes vs CAS Unique Raw Bytes now show correct values).
CLI rejects ambiguous subcommands (e.g., yams search graph → use --query).
--paths-only search now returns results correctly.
yams watch waits for daemon ready; always ignores .git contents.
Expanded prune patterns for build artifacts and language caches.
Fixed ONNX model loading deadlock on Windows (single-flight pattern, recursive mutex).
Streaming: 30s chunk timeout, backpressure stops producer on queue overflow.
yams add returns immediately; hash computed async during ingestion.
Replaced experimental Boost.Asio APIs with stable async_initiate (fixes TSAN races).
