Changes in synapse v0.31.1 (2018-06-08)
=======================================
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
These "temporary fixes" have been here three and a half years, and I can't find
any events in the matrix.org database where the calculated signature differs
from what's in the db. It's time for them to go away.
======================================
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)

The added addresses are expected to be local or loopback addresses and
shouldn't be spidered for previews.

The pagination storage function supported not specifiying a limit on the
number of events returned. This was triggered when using the search or
context API with a limit of zero, which the storage function took to
mean not being limited.
The transaction cache has some code which tries to stop it caching failures,
but if the callback function failed straight away, then things would happen
backwards and we'd end up with the failure stuck in the cache.
There's a frequent idiom I noticed where an iterable is split up into a
number of chunks/batches. Unfortunately that method does not work with
iterators like dict.keys() in python3. This implementation works with
iterators.

Server Notices use a special room which the user can't dismiss. They are
created on demand when some other bit of the code calls send_notice.
(This doesn't actually do much yet becuse we don't call send_notice anywhere)
This simplifies things as it is, but will also allow us to change the
way we traverse topologically without having to update the way push
actions work.
(instead of everywhere that writes a response. Or rather, the subset of places
which write responses where we haven't forgotten it).
This also means that we don't have to have the mysterious version_string
attribute in anything with a request handler.
Unfortunately it does mean that we have to pass the version string wherever we
instantiate a SynapseSite, which has been c&ped 150 times, but that is code
that ought to be cleaned up anyway really.
This is useful in its own right, because server.py is full of stuff; but more
importantly, I want to do some refactoring that will cause a circular reference
as it is.
The sync API often returns events in a topological rather than stream
ordering, e.g. when the user joined the room or on initial sync. When
this happens we can reuse existing pagination storage functions.
There is no reason to return a tuple of tokens when the last token is
always the token passed as an argument. Changing it makes it consistent
with other storage APIs
