When _get_state_for_groups is given a wildcard filter, just do a complete
lookup. Hopefully this will give us the best of both worlds by not filling up
the ram if we only need one or two keys, but also making the cache still work
for the federation reader usecase.
When we finish processing a request, log the number of events we fetched from
the database to handle it.
[I'm trying to figure out which requests are responsible for large amounts of
event cache churn. It may turn out to be more helpful to add counts to the
prometheus per-request/block metrics, but that is an extension to this code
anyway.]
when there is no `m.room.power_levels` event in force in the room. (PR #3397)

SECURITY UPDATE: Prevent unauthorised users from setting state events in a room
when there is no `m.room.power_levels` event in force in the room. (PR #3397)
Discussion around the Matrix Spec change proposal for this change can be
followed at https://github.com/matrix-org/matrix-doc/issues/1304.
This is only used by filter_events_for_client, so we can simplify the whole
thing by just doing one user at a time, and removing a dead storage function to
boot.
=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)

=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)
Firstly, don't swallow the reason for the failure
Secondly, don't assume all exceptions are verification failures
Thirdly, log a bit of info about the key being used if debug is enabled
======================================
Most notable change from v0.30.0 is to switch to 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 LaterGuage error handling (694968f)
* Fix replication metrics (b7e7fd2)
