Hi folks; today we are releasing Synapse 1.7.1.
|
|
|
|
This is a security release which fixes some problems which affected all previous versions of Synapse. We advise all admins whose servers are open to public federation to upgrade as soon as possible.
|
|
|
|
Full details follow, but the most important change improves event authorization, thereby preventing the ability to add certain events to a given room erroneously.
|
|
|
|
You can get the new release from [github](https://github.com/matrix-org/synapse/releases/tag/v1.7.1) or any of the sources mentioned at https://github.com/matrix-org/synapse/blob/master/INSTALL.md.
