Well now, Synapse 1.3.0 is here.
|
||
|
||
The main thing to know about 1.3.0 is that is contains performance improvements to reduce disk I/O and reduce RAM usage. We’ve been running it on matrix.org for a week or so and are really pleased with the results.
|
||
|
||
Check out our message send heat map.
|
||
|
||
|
||
|
||
|
||
Other than that there are a bunch of bug fixes and tweaks to generally make things run more smoothly.
|
||
|
||
As ever, you can get the new update [here](https://github.com/matrix-org/synapse/releases/tag/v1.3.0) or any of the sources mentioned at [https://github.com/matrix-org/synapse](https://github.com/matrix-org/synapse).

Synapse 1.3.0 (2019-08-15)
|
||
==========================
|
||
|
||
Bugfixes
|
||
--------
|
||
|
||
- Fix 500 Internal Server Error on `publicRooms` when the public room list was
|
||
cached. ([\#5851](https://github.com/matrix-org/synapse/issues/5851))
|
||
|
||
|
||
Synapse 1.3.0rc1 (2019-08-13)
|
||
==========================
|
||
|
||
Features
|
||
--------
|
||
|
||
- Use `M_USER_DEACTIVATED` instead of `M_UNKNOWN` for errcode when a deactivated user attempts to login. ([\#5686](https://github.com/matrix-org/synapse/issues/5686))
|
||
- Add sd_notify hooks to ease systemd integration and allows usage of Type=Notify. ([\#5732](https://github.com/matrix-org/synapse/issues/5732))
|
||
- Synapse will no longer serve any media repo admin endpoints when `enable_media_repo` is set to False in the configuration. If a media repo worker is used, the admin APIs relating to the media repo will be served from it instead. ([\#5754](https://github.com/matrix-org/synapse/issues/5754), [\#5848](https://github.com/matrix-org/synapse/issues/5848))
|
||
- Synapse can now be configured to not join remote rooms of a given "complexity" (currently, state events) over federation. This option can be used to prevent adverse performance on resource-constrained homeservers. ([\#5783](https://github.com/matrix-org/synapse/issues/5783))
|
||
- Allow defining HTML templates to serve the user on account renewal attempt when using the account validity feature. ([\#5807](https://github.com/matrix-org/synapse/issues/5807))
|
||
|
||
|
||

|
||
- Fix stack overflow in server key lookup code. ([\#5724](https://github.com/matrix-org/synapse/issues/5724))
|
||
- start.sh no longer uses deprecated cli option. ([\#5725](https://github.com/matrix-org/synapse/issues/5725))

|
||
- Fix debian packaging scripts to correctly build sid packages. ([\#5775](https://github.com/matrix-org/synapse/issues/5775))
|
||
- Correctly handle redactions of redactions. ([\#5788](https://github.com/matrix-org/synapse/issues/5788))
|
||
- Return 404 instead of 403 when accessing /rooms/{roomId}/event/{eventId} for an event without the appropriate permissions. ([\#5798](https://github.com/matrix-org/synapse/issues/5798))
|
||
- Fix check that tombstone is a state event in push rules. ([\#5804](https://github.com/matrix-org/synapse/issues/5804))
|
||
- Fix error when trying to login as a deactivated user when using a worker to handle login. ([\#5806](https://github.com/matrix-org/synapse/issues/5806))
|
||
- Fix bug where user `/sync` stream could get wedged in rare circumstances. ([\#5825](https://github.com/matrix-org/synapse/issues/5825))
|
||
- The purge_remote_media.sh script was fixed. ([\#5839](https://github.com/matrix-org/synapse/issues/5839))
|
||
|
||
|
||
Deprecations and Removals
|
||
-------------------------
|
||
|
||
- Synapse now no longer accepts the `-v`/`--verbose`, `-f`/`--log-file`, or `--log-config` command line flags, and removes the deprecated `verbose` and `log_file` configuration file options. Users of these options should migrate their options into the dedicated log configuration. ([\#5678](https://github.com/matrix-org/synapse/issues/5678), [\#5729](https://github.com/matrix-org/synapse/issues/5729))
