In the excitement of KamailioWorld last week we completely forgot to mention that we released Synapse 0.9.1.

This is a pretty important performance and stability update of all the new stuff that landed in 0.9.0, as well as landing a major new feature in the form of ‘backfill’: we finally have the ability to correctly sync in historical conversation history over federation for newly federated rooms. In other words, if you join a remote room you should be able to navigate its history as intended.

We highly recommend upgrading to 0.9.1 for all the performance improvements and backfill support – get it now from http://github.com/matrix-org/synapse.


Changes in synapse v0.9.1 (2015-05-26)
======================================

General:

* Add support for backfilling when a client paginates. This allows servers to
request history for a room from remote servers when a client tries to
paginate history the server does not have - SYN-36
* Fix bug where you couldn't disable non-default pushrules - SYN-378
* Fix ``register_new_user`` script - SYN-359
* Improve performance of fetching events from the database, this improves both
initialSync and sending of events.
* Improve performance of event streams, allowing synapse to handle more
simultaneous connected clients.

Federation:

* Fix bug with existing backfill implementation where it returned the wrong
selection of events in some circumstances.
* Improve performance of joining remote rooms.

Configuration:

* Add support for changing the bind host of the metrics listener via the
``metrics_bind_host`` option.
