+Changes in synapse v0.31.1 (2018-06-08)
+=======================================
+
+v0.31.1 fixes a security bug in the ``get_missing_events`` federation API

+Changes in synapse v0.31.0 (2018-06-06)
+=======================================
+
+Most notable change from v0.30.0 is to switch to the python prometheus library to improve system
+stats reporting. WARNING: this changes a number of prometheus metrics in a
+backwards-incompatible manner. For more details, see
+`docs/metrics-howto.rst <docs/metrics-howto.rst#removal-of-deprecated-metrics--time-based-counters-becoming-histograms-in-0310>`_.
+
+Bug Fixes:
+
+* Fix metric documentation tables (PR #3341)
+* Fix LaterGauge error handling (694968f)
+* Fix replication metrics (b7e7fd2)
+
+Changes in synapse v0.31.0-rc1 (2018-06-04)

+
+* daily user type phone home stats (PR #3264)
+* Use iter* methods for _filter_events_for_server (PR #3267)
+* Docs on consent bits (PR #3268)
+* Remove users from user directory on deactivate (PR #3277)
+* Avoid sending consent notice to guest users (PR #3288)
+* disable CPUMetrics if no /proc/self/stat (PR #3299)
+* Consistently use six's iteritems and wrap lazy keys/values in list() if they're not meant to be lazy (PR #3307)
+* Add private IPv6 addresses to example config for url preview blacklist (PR #3317) Thanks to @thegcat!
+* Reduce stuck read-receipts: ignore depth when updating (PR #3318)
+* Put python's logs into Trial when running unit tests (PR #3319)
