+
+
+Bugfixes
+--------
+
+- Prevent clients from reporting nonexistent events. ([\#13779](https://github.com/matrix-org/synapse/issues/13779))
+- Return spec-compliant JSON errors when unknown endpoints are requested. ([\#14605](https://github.com/matrix-org/synapse/issues/14605))
+- Fix a long-standing bug where the room aliases returned could be corrupted. ([\#15038](https://github.com/matrix-org/synapse/issues/15038))
+- Fix a bug introduced in Synapse 1.76.0 where partially-joined rooms could not be deleted using the [purge room API](https://matrix-org.github.io/synapse/latest/admin_api/rooms.html#delete-room-api). ([\#15068](https://github.com/matrix-org/synapse/issues/15068))
+- Fix a long-standing bug where federated joins would fail if the first server in the list of servers to try is not in the room. ([\#15074](https://github.com/matrix-org/synapse/issues/15074))
+- Fix a bug introduced in Synapse v1.74.0 where searching with colons when using ICU for search term tokenisation would fail with an error. ([\#15079](https://github.com/matrix-org/synapse/issues/15079))
+- Reduce the likelihood of a rare race condition where rejoining a restricted room over federation would fail. ([\#15080](https://github.com/matrix-org/synapse/issues/15080))
+- Fix a bug introduced in Synapse 1.76 where workers would fail to start if the `health` listener was configured. ([\#15096](https://github.com/matrix-org/synapse/issues/15096))
+- Fix a bug introduced in Synapse 1.75 where the [portdb script](https://matrix-org.github.io/synapse/release-v1.78/postgres.html#porting-from-sqlite) would fail to run after a room had been faster-joined. ([\#15108](https://github.com/matrix-org/synapse/issues/15108))
+
+
+Improved Documentation
+----------------------
+
+- Document how to start Synapse with Poetry. Contributed by @thezaidbintariq. ([\#14892](https://github.com/matrix-org/synapse/issues/14892), [\#15022](https://github.com/matrix-org/synapse/issues/15022))
+- Update delegation documentation to clarify that SRV DNS delegation does not eliminate all needs to serve files from .well-known locations. Contributed by @williamkray. ([\#14959](https://github.com/matrix-org/synapse/issues/14959))
+- Fix a mistake in registration_shared_secret_path docs. ([\#15078](https://github.com/matrix-org/synapse/issues/15078))
+- Refer to a more recent blog post on the [Database Maintenance Tools](https://matrix-org.github.io/synapse/latest/usage/administration/database_maintenance_tools.html) page. Contributed by @jahway603. ([\#15083](https://github.com/matrix-org/synapse/issues/15083))
+
+
+Internal Changes
+----------------
+
+- Re-type hint some collections as read-only. ([\#13755](https://github.com/matrix-org/synapse/issues/13755))
+- Faster joins: don't stall when another user joins during a partial-state room resync. ([\#14606](https://github.com/matrix-org/synapse/issues/14606))
+- Add a class `UnpersistedEventContext` to allow for the batching up of storing state groups. ([\#14675](https://github.com/matrix-org/synapse/issues/14675))
+- Add a check to ensure that locked dependencies have source distributions available. ([\#14742](https://github.com/matrix-org/synapse/issues/14742))
+- Tweak comment on `_is_local_room_accessible` as part of room visibility in `/hierarchy` to clarify the condition for a room being visible. ([\#14834](https://github.com/matrix-org/synapse/issues/14834))
+- Prevent `WARNING: there is already a transaction in progress` lines appearing in PostgreSQL's logs on some occasions. ([\#14840](https://github.com/matrix-org/synapse/issues/14840))
+- Use `StrCollection` to avoid potential bugs with `Collection[str]`. ([\#14929](https://github.com/matrix-org/synapse/issues/14929))
+- Improve performance of `/sync` in a few situations. ([\#14973](https://github.com/matrix-org/synapse/issues/14973))
+- Limit concurrent event creation for a room to avoid state resolution when sending bursts of events to a local room. ([\#14977](https://github.com/matrix-org/synapse/issues/14977))
+- Skip calculating unread push actions in /sync when enable_push is false. ([\#14980](https://github.com/matrix-org/synapse/issues/14980))
+- Add a schema dump symlinks inside `contrib`, to make it easier for IDEs to interrogate Synapse's database schema. ([\#14982](https://github.com/matrix-org/synapse/issues/14982))
+- Improve type hints. ([\#15008](https://github.com/matrix-org/synapse/issues/15008), [\#15026](https://github.com/matrix-org/synapse/issues/15026), [\#15027](https://github.com/matrix-org/synapse/issues/15027), [\#15028](https://github.com/matrix-org/synapse/issues/15028), [\#15031](https://github.com/matrix-org/synapse/issues/15031), [\#15035](https://github.com/matrix-org/synapse/issues/15035), [\#15052](https://github.com/matrix-org/synapse/issues/15052), [\#15072](https://github.com/matrix-org/synapse/issues/15072), [\#15084](https://github.com/matrix-org/synapse/issues/15084))
+- Update [MSC3952](https://github.com/matrix-org/matrix-spec-proposals/pull/3952) support based on changes to the MSC. ([\#15037](https://github.com/matrix-org/synapse/issues/15037))
+- Avoid mutating a cached value in `get_user_devices_from_cache`. ([\#15040](https://github.com/matrix-org/synapse/issues/15040))
+- Fix a rare exception in logs on start up. ([\#15041](https://github.com/matrix-org/synapse/issues/15041))
+- Update pyo3-log to v0.8.1. ([\#15043](https://github.com/matrix-org/synapse/issues/15043))
+- Avoid mutating cached values in `_generate_sync_entry_for_account_data`. ([\#15047](https://github.com/matrix-org/synapse/issues/15047))
+- Refactor arguments of `try_unbind_threepid` and `_try_unbind_threepid_with_id_server` to not use dictionaries. ([\#15053](https://github.com/matrix-org/synapse/issues/15053))
+- Merge debug logging from the hotfixes branch. ([\#15054](https://github.com/matrix-org/synapse/issues/15054))
+- Faster joins: omit device list updates originating from partial state rooms in /sync responses without lazy loading of members enabled. ([\#15069](https://github.com/matrix-org/synapse/issues/15069))
+- Fix clashing database transaction name. ([\#15070](https://github.com/matrix-org/synapse/issues/15070))
+- Upper-bound frozendict dependency. This works around us being unable to test installing our wheels against Python 3.11 in CI. ([\#15114](https://github.com/matrix-org/synapse/issues/15114))
+- Tweak logging for when a worker waits for its view of a replication stream to catch up. ([\#15120](https://github.com/matrix-org/synapse/issues/15120))

+
+Synapse 1.76.0 (2023-01-31)
+===========================
+
+The 1.76 release is the first to enable faster joins ([MSC3706](https://github.com/matrix-org/matrix-spec-proposals/pull/3706) and [MSC3902](https://github.com/matrix-org/matrix-spec-proposals/pull/3902)) by default. Admins can opt-out: see [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#faster-joins-are-enabled-by-default) for more details.
+
+The upgrade from 1.75 to 1.76 changes the account data replication streams in a backwards-incompatible manner. Server operators running a multi-worker deployment should consult [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#changes-to-the-account-data-replication-streams).
+
+Those who are `poetry install`ing from source using our lockfile should ensure their poetry version is 1.3.2 or higher; [see upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.76/docs/upgrade.md#minimum-version-of-poetry-is-now-132).
+
+
+Notes on faster joins
+---------------------
+
+The faster joins project sees the most benefit when joining a room with a large number of members (joined or historical). We expect it to be particularly useful for joining large public rooms like the [Matrix HQ](https://matrix.to/#/#matrix:matrix.org) or [Synapse Admins](https://matrix.to/#/#synapse:matrix.org) rooms. 
+
+After a faster join, Synapse considers that room "partially joined". In this state, you should be able to
+
+- read incoming messages;
+- see incoming state changes, e.g. room topic changes; and
+- send messages, if the room is unencrypted.
+
+Synapse has to spend more effort to complete the join in the background. Once this finishes, you will be able to
+
+- send messages, if the room is in encrypted;
+- retrieve room history from before your join, if permitted by the room settings; and
+- access the full list of room members.
+
+
+Improved Documentation

+
+
+Internal Changes
+----------------
+
+- Faster joins: Improve performance of looking up partial-state status of rooms. ([\#14917](https://github.com/matrix-org/synapse/issues/14917))

+# Schema symlinks
+
+This directory contains symlinks to the latest dump of the postgres full schema. This is useful to have, as it allows IDEs to understand our schema and provide autocomplete, linters, inspections, etc.
+
+In particular, the DataGrip functionality in IntelliJ's products seems to only consider files called `*.sql` when defining a schema from DDL; `*.sql.postgres` will be ignored. To get around this we symlink those files to ones ending in `.sql`. We've chosen to ignore the `.sql.sqlite` schema dumps here, as they're not intended for production use (and are much quicker to test against).
+
+## Example
+![](datagrip-aware-of-schema.png)
+
+## Caveats
+
+- Doesn't include temporary tables created ad-hoc by Synapse.
+- Postgres only. IDEs will likely be confused by SQLite-specific queries.
+- Will not include migrations created after the latest schema dump.
+- Symlinks might confuse checkouts on Windows systems.
+
+## Instructions
+
+### Jetbrains IDEs with DataGrip plugin
+
+- View -> Tool Windows -> Database
+- `+` Icon -> DDL Data Source
+- Pick a name, e.g. `Synapse schema dump`
+- Under sources, click `+`.
+- Add an entry with Path pointing to this directory, and dialect set to PostgreSQL.
+- OK, and OK.
+- IDE should now be aware of the schema.
+- Try control-clicking on a table name in a bit of SQL e.g. in `_get_forgotten_rooms_for_user_txn`.

+`less`, `grep`, etc.
+
+This directory contains an `lnav` [log format definition](
+    https://docs.lnav.org/en/v0.10.1/formats.html#defining-a-new-format
+) for Synapse logs as
+emitted by Synapse with the default [logging configuration](
+    https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#log_config
+). It supports lnav 0.10.1 because that's what's packaged by my distribution.
+
+This should allow lnav:
+
+- to interpret timestamps, allowing log interleaving;
+- to interpret log severity levels, allowing colouring by log level(!!!);
+- to interpret request IDs, allowing you to skip through a specific request; and
+- to highlight room, event and user IDs in logs.
+
+See also https://gist.github.com/benje/e2ab750b0a81d11920d83af637d289f7 for a
+ similar example.
+
+## Example
+
+[![asciicast](https://asciinema.org/a/556133.svg)](https://asciinema.org/a/556133)
+
+## Tips
+
+- `lnav -i /path/to/synapse/checkout/contrib/lnav/synapse-log-format.json`
+- `lnav my_synapse_log_file` or `lnav synapse_log_files.*`, etc.
+- `lnav --help` for CLI help.
+
+Within lnav itself:
+
+- `?` for help within lnav itself.
+- `q` to quit.
+- `/` to search a-la `less` and `vim`, then `n` and `N` to continue searching 
+  down and up.
+- Use `o` and `O` to skip through logs based on the request ID (`POST-1234`, or
+  else the value of the [`request_id_header`](
+    https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html?highlight=request_id_header#listeners
+  ) header). This may get confused if the same request ID is repeated among 
+  multiple files or process restarts.
+- ???
+- Profit
