No significant changes.

[0.17.0] - 2026-05-08

Features

• Add support in the implementation of EventCacheStore for having duplicate events in a room, where each duplicate is in a different LinkedChunk. This is useful, e.g., when an event is in a room and a thread in that room. The change involves a database migration where the EVENTS object store is cleared and then modified so that the ROOM index no longer requires keys to be unique. (#6200)
• Implement CryptoStore::get_pending_key_bundle_details_for_room and CryptoStore::get_all_rooms_pending_key_bundle, and process rooms_pending_key_bundle field in Changes. (#6199), (#6233)
• Expose implementations of EventCacheStore and MediaStore and add a composite type for initializing all stores with a single function - i.e., IndexeddbStores::open. Additionally, allow feature flags for each of the stores to be used independent of and in combination with the others. (#5946)
• Implement new method CyptoStore::has_downloaded_all_room_keys, and process room_key_backups_fully_downloaded field in Changes. (#6017) (#6044)
• [breaking] In EventCacheStore::handle_linked_chunk_updates, new chunks may no longer reference chunk identifiers which do not yet exist in the store (#6061)

Bug fixes

• Ensure that encrypted tests are run with a StoreCipher. This happened to reveal tests which fail in an encrypted EventCacheStore, which required fixing queries for all events in a room. (#5933)

Refactor

• Add migration to IndexeddbCryptoStore that removes cross-process lock generation key from CORE object store, as this is tracked in LEASE_LOCKS object store. (#6326)

[0.16.1] - 2026-05-08

No notable changes in this release.

[0.16.0] - 2025-12-04

Features

• Implement new method CryptoStore::get_withheld_sessions_by_room_id. (#5819)
• [breaking] IndexeddbCryptoStore::get_withheld_info now returns Result<Option<RoomKeyWithheldEntry>, ...>. (#5737)
• Implement StateStore::upsert_thread_subscriptions() method for bulk upserts. (#5848)

Performance

• Improve performance of certain media queries in MediaStore implementation by storing media content and media metadata in separate object stores in IndexedDB (see #5795).

[0.14.0] - 2025-09-04

No notable changes in this release.

[0.13.0] - 2025-07-10

Features

• Add support for received room key bundle data, as required by encrypted history sharing ((MSC4268)[https://github.com/matrix-org/matrix-spec-proposals/pull/4268)). (#5276)

[0.8.0] - 2024-11-19

Features

• Improve the efficiency of objects stored in the crypto store. (#3645, #3651)

Bug fixes

• Use the DisplayName struct to protect against homoglyph attacks.
