Today we release Synapse 0.27.3!
|
||
|
||
Hot on the heels of 0.27.2, notable changes include API support for joining groups/communities as well as a major bug fix (<a class="issue-link js-issue-link" href="https://github.com/matrix-org/synapse/pull/3082" data-error-text="Failed to load issue title" data-id="312859684" data-permission-text="Issue title is private" data-url="https://github.com/matrix-org/synapse/issues/3082">#3082</a>), that is particularly important for those upgrading for the first time in a while. Also new metrics and phone home stats. Phone home stats include better visibility of system usage so we can have a better idea of how synapse's RAM and CPU is behaving in the wild. Also, recording the number of users on the server who have been using it for at least 30 days.
|
||
|
||
Phone home stats are entirely optional and can be enabled/disabled by setting "<span class="s1">report_</span>
|
||
<span class="s2">stat</span>
|
||
<span class="s1">s" in homeserver.yaml. </span>
|
||
Please consider enabling phone home stats if you currently have not done so - this data is really important to us in improving Matrix as a whole (and justifying future funding for <a class="linkified" href="http://matrix.org/" target="_blank" rel="noopener">Matrix.org</a>).
|
||
|
||
As always, you can get it from <a href="https://github.com/matrix-org/synapse/releases/tag/v0.27.3">https://github.com/matrix-org/synapse/releases/tag/v0.27.3</a> and thanks to everyone who tested the release candidates.

### Changes in synapse v0.27.3 (2018-04-11)
|
||
|
||
Bug fixes:
|
||
<ul>
|
||
<li>URL quote path segments over federation (<a class="issue-link js-issue-link" href="https://github.com/matrix-org/synapse/pull/3082" data-error-text="Failed to load issue title" data-id="312859684" data-permission-text="Issue title is private" data-url="https://github.com/matrix-org/synapse/issues/3082">#3082</a>)</li>
|
||
</ul>
|
||
|
||
### Changes in synapse v0.27.3-rc2 (2018-04-09)
|
||
|
||
v0.27.3-rc1 used a stale version of the develop branch so the changelog overstates
|
||
the functionality. v0.27.3-rc2 is up to date, rc1 should be ignored.
|
||
|
||
### Changes in synapse v0.27.3-rc1 (2018-04-09)
|
||
|
||
Notable changes include API support for joinability of groups. Also new metrics
|
||
and phone home stats. Phone home stats include better visibility of system usage
|
||
so we can tweak synpase to work better for all users rather than our own experience
|
||
with matrix.org. Also, recording 'r30' stat which is the measure we use to track
|
||
overall growth of the Matrix ecosystem. It is defined as:-
|
||
|
||
Counts the number of native 30 day retained users, defined as:-
|
||
* Users who have created their accounts more than 30 days
|
||
* Where last seen at most 30 days ago
|
||
* Where account creation and last_seen are > 30 days"

||
