    🛠 Bugfixes

    • 🛠 Fix detection of out of sync remote device lists when receiving events from remote users. (#7815)
    • 🛠 Fix bug where Synapse fails to process an incoming event over federation if the server is missing too much of the event's auth chain. (#7817)

    Synapse 1.17.0 (2020-07-13)

    Synapse 1.17.0 is identical to 1.17.0rc1, with the addition of the fix that was included in 1.16.1.

    Synapse 1.16.1 (2020-07-10)

    🚀 In some distributions of Synapse 1.16.0, we incorrectly included a database migration which added a new, unused table. This release removes the redundant table.
