We just pushed a bugfix update to Synapse 0.5, mainly to fix a memory leak where federated events could get leaked whilst retrying to send them to a remote server which is unavailable. Please upgrade, especially if you’ve noticed synapse hogging RAM!


Changes in synapse 0.5.4 (2014-12-03)
=====================================

* Fix presence bug where some rooms did not display presence updates for
remote users.
* Do not log SQL timing log lines when started with "-v"
* Fix potential memory leak.
