Changes in synapse v0.28.0-rc1 (2018-04-26) Changes in synapse v0.28.1 (2018-05-01)
=========================================== =======================================
SECURITY UPDATE
* Clamp the allowed values of event depth received over federation to be
[0, 2**63 - 1]. This mitigates an attack where malicious events
injected with depth = 2**63 - 1 render rooms unusable. Depth is used to
determine the cosmetic ordering of events within a room, and so the ordering
of events in such a room will default to using stream_ordering rather than depth
(topological_ordering).
This is a temporary solution to mitigate abuse in the wild, whilst a long solution
is being implemented to improve how the depth parameter is used.

* Pin Twisted to <18.4 until we stop using the private _OpenSSLECCurve API.
