v0.5.0

Added

• Add browser support for reading, ingesting, and querying a Teams cache.
• Add a ./web entry point built on a pluggable SqlDriver seam, with a node:sqlite driver and an optional @sqlite.org/sqlite-wasm browser driver at libzaungast/web/sqlite-wasm-driver (installed separately, only if you use it).
• Add openStoreFromSource, a single build path that behaves identically in Node and the browser, with an optional onPhase hook for build-progress reporting.
• Speed up the first read with an optional Web Worker pool (createPool, handlePoolMessage, openStoreFromSourceParallel, extractFromSourceParallel) that parses .ldb files and extracts records in parallel, falling back to serial automatically.
• Add a deferFts option to build the full-text search index lazily on first search instead of during ingest.
• Add an engine-agnostic data seam (shapeBaseTables, deriveTables, baseMeta, and named row types), a read-only rawDb accessor, and topic-scorer exports, so a non-SQLite backend or custom analytics can build a byte-matching store.
• Add organization, profile type, and structured given/surname names to people, recovered for federated (external) contacts.

Full Changelog: v0.4.0...v0.5.0

v0.4.0

Added

• Publish the reader as a standalone libzaungast package with a public data facade, split out from the zaungast MCP server.
• Add an optional native (Rust) ingest engine, libzaungast-native, selectable via ZAUNGAST_ENGINE, with byte-identical output and an incremental-refresh path.
• Add get_message and read_thread tools.
• Render channel conversations by reply-chain (threaded).
• Persist conversation thread type, as a foundation for Teams Communities data.

Changed

• Rename the top_topics tool to rank_topics, and read_messages to read_conversation (per-thread and single-message reads move to the new read_thread and get_message tools).
• Report the real package version in the MCP server info and startup banner.
• Speed up ingest and structured-clone decode via whole-file reads, memoized prefix decoding, single-pass HTML-to-text, and delta full-text indexing on refresh.

Fixed

• Match the Teams schema by exact fingerprint through a versioned mapping registry, instead of guessing.

Full Changelog: v0.3.0...v0.4.0

v0.3.0

Added

• Add list_events and list_calls tools for calendar events and call history.
• Auto-discover the Teams store on macOS.

Fixed

• Label your own messages with your name and (you) instead of ME.
• Encode chain_key NUL-safely (hex) so reply-chain keys containing NUL bytes ingest correctly.

Full Changelog: v0.2.0...v0.3.0

v0.2.0

Added

• Render emoji reactions in read_messages.
• Decode Blink blob values (kHostObject), completing structured-clone value coverage.

Changed

• Speed up structured-clone decode by roughly 2×.

Fixed

• Decode BigInt values instead of substituting 0.

Full Changelog: v0.1.1...v0.2.0

v0.1.1

Re-release of 0.1.0 with no functional changes.

Fixed

• Add the repository metadata npm requires for a provenance publish.

Full Changelog: v0.1.0...v0.1.1

v0.1.0

Initial release.

Added

• Provide six read-only MCP tools: list_conversations, read_messages, search, top_topics, find_person, and describe_schema.
• Read the Chromium IndexedDB-on-LevelDB store the Teams app writes in pure JavaScript — an SSTable and write-ahead-log parser, a Snappy decoder, Chromium IndexedDB key coding, and a Blink/V8 structured-clone deserializer — with no native dependencies and no idb_cmp1 comparator (full scan plus sequence-number dedup).
• Auto-discover the local Teams IndexedDB directory with zero configuration (override with TEAMS_LEVELDB_DIR).
• Index the data in an in-memory SQLite database (node:sqlite) with FTS5 full-text search.
• Refresh incrementally in two modes — copy-reuse (default; reuses immutable .ldb parses and re-reads only the write-ahead log) and reparse (ZAUNGAST_INCREMENTAL=reparse) — proven to produce identical results.
• Score top_topics by distinctiveness against a baseline, with bot exclusion, per-call exclude (words or handles), and arbitrary since/until windows.
• Disclose the local cache horizon: empty or edge results report the coverage window, so a quiet result is never mistaken for "the cache doesn't reach that far".
• Ship extensible English and German stopword sets.
• Guarantee read-only access — the live Teams directory is only ever read or copied, never opened for writing, locked, or memory-mapped, so the reader cannot corrupt the Teams store.
