- Matrix docs: full Proxy Mode section with architecture diagram,
step-by-step setup (host + Docker), docker-compose.yml/Dockerfile
examples, configuration reference, and limitations notes
- API Server docs: add Proxy Mode section explaining the api_server
serves as the backend for gateway proxy mode
- Environment variables reference: add GATEWAY_PROXY_URL and
GATEWAY_PROXY_KEY entries
Follow-up for cherry-picked PR #8272:
- Add MATRIX_RECOVERY_KEY to module docstring header in matrix.py
- Register in OPTIONAL_ENV_VARS (config.py) with password=True, advanced=True
- Add to _NON_SETUP_ENV_VARS set
- Document cross-signing verification in matrix.md E2EE section
- Update migration guide with recovery key step (step 3)
- Add to environment-variables.md reference
Fixes#7952 — Matrix E2EE completely broken after mautrix migration.
- Replace MemoryCryptoStore + pickle/HMAC persistence with mautrix's
PgCryptoStore backed by SQLite via aiosqlite. Crypto state now
persists reliably across restarts without fragile serialization.
- Add handle_sync() call on initial sync response so to-device events
(queued Megolm key shares) are dispatched to OlmMachine instead of
being silently dropped.
- Add _verify_device_keys_on_server() after loading crypto state.
Detects missing keys (re-uploads), stale keys from migration
(attempts re-upload), and corrupted state (refuses E2EE).
- Add _CryptoStateStore adapter wrapping MemoryStateStore to satisfy
mautrix crypto's StateStore interface (is_encrypted,
get_encryption_info, find_shared_rooms).
- Remove redundant share_keys() call from sync loop — OlmMachine
already handles this via DEVICE_OTK_COUNT event handler.
- Fix datetime vs float TypeError in session.py suspend_recently_active()
that crashed gateway startup.
- Add aiosqlite and asyncpg to [matrix] extra in pyproject.toml.
- Update test mocks for PgCryptoStore/Database and add query_keys mock
for key verification. 174 tests pass.
- Add E2EE upgrade/migration docs to Matrix user guide.
When enabled, @mentioning the bot in a DM creates a thread (default:
false). Supports both env var and YAML config (matrix.dm_mention_threads).
6 new tests, docs updated.
From #6957
Bring Matrix feature parity with Discord by adding mention gating and
auto-threading. Both default to true, matching Discord behavior.
