Changes in synapse v0.13.3 (2016-02-11)
=======================================
* Fix bug where ``/sync`` would occasionally return events in the wrong room.
Changes in synapse v0.13.2 (2016-02-11)
=======================================
* Fix bug where ``/events`` would fail to skip some events if there had been
more events than the limit specified since the last request (PR #570)
Changes in synapse v0.13.1 (2016-02-10)
=======================================
* Bump matrix-angular-sdk (matrix web console) dependency to 0.6.8 to
pull in the fix for SYWEB-361 so that the default client can display
HTML messages again(!)
Changes in synapse v0.13.0 (2016-02-10)
=======================================
This version includes an upgrade of the schema, specifically adding an index to
the ``events`` table. This may cause synapse to pause for several minutes the
first time it is started after the upgrade.
Changes:
* Improve general performance (PR #540, #543. #544, #54, #549, #567)
* Change guest user ids to be incrementing integers (PR #550)
* Improve performance of public room list API (PR #552)
* Change profile API to omit keys rather than return null (PR #557)
* Add ``/media/r0`` endpoint prefix, which is equivalent to ``/media/v1/``
(PR #595)
Bug fixes:
* Fix bug with upgrading guest accounts where it would fail if you opened the
registration email on a different device (PR #547)
* Fix bug where unread count could be wrong (PR #568)
Changes in synapse v0.12.1-rc1 (2016-01-29)
===========================================
Features:
* Add unread notification counts in ``/sync`` (PR #456)
* Add support for inviting 3pids in ``/createRoom`` (PR #460)
* Add ability for guest accounts to upgrade (PR #462)
* Add ``/versions`` API (PR #468)
* Add ``event`` to ``/context`` API (PR #492)
* Add specific error code for invalid user names in ``/register`` (PR #499)
* Add support for push badge counts (PR #507)
* Add support for non-guest users to peek in rooms using ``/events`` (PR #510)
Changes:
* Change ``/sync`` so that guest users only get rooms they've joined (PR #469)
* Change to require unbanning before other membership changes (PR #501)
* Change default push rules to notify for all messages (PR #486)
* Change default push rules to not notify on membership changes (PR #514)
* Change default push rules in one to one rooms to only notify for events that
are messages (PR #529)
* Change ``/sync`` to reject requests with a ``from`` query param (PR #512)
* Change server manhole to use SSH rather than telnet (PR #473)
* Change server to require AS users to be registered before use (PR #487)
* Change server not to start when ASes are invalidly configured (PR #494)
* Change server to require ID and ``as_token`` to be unique for AS's (PR #496)
* Change maximum pagination limit to 1000 (PR #497)
Bug fixes:
* Fix bug where ``/sync`` didn't return when something under the leave key
changed (PR #461)
* Fix bug where we returned smaller rather than larger than requested
thumbnails when ``method=crop`` (PR #464)
* Fix thumbnails API to only return cropped thumbnails when asking for a
cropped thumbnail (PR #475)
* Fix bug where we occasionally still logged access tokens (PR #477)
* Fix bug where ``/events`` would always return immediately for guest users
(PR #480)
* Fix bug where ``/sync`` unexpectedly returned old left rooms (PR #481)
* Fix enabling and disabling push rules (PR #498)
* Fix bug where ``/register`` returned 500 when given unicode username
(PR #513)

Password reset
==============
If a user has registered an email address to their account using an identity
server, they can request a password-reset token via clients such as Vector.
A manual password reset can be done via direct database access as follows.
First calculate the hash of the new password:
$ source ~/.synapse/bin/activate
$ ./scripts/hash_password

Halp!! Synapse eats all my RAM!
===============================
Synapse's architecture is quite RAM hungry currently - we deliberately
cache a lot of recent room data and metadata in RAM in order to speed up
common requests. We'll improve this in future, but for now the easiest
way to either reduce the RAM usage (at the risk of slowing things down)
is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
variable. Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1.0 will max out
at around 3-4GB of resident memory - this is what we currently run the
matrix.org on. The default setting is currently 0.1, which is probably
around a ~700MB footprint. You can dial it down further to 0.02 if
desired, which targets roughly ~512MB. Conversely you can dial it up if
you need performance for lots of users and have a box with a lot of RAM.

If there is no data for any of the supplied streams after the given
position then the request will block until there is data for one
of the streams. This allows clients to long-poll this API.
The possible streams are:
* "streams": A special stream returing the positions of other streams.
* "events": The new events seen on the server.
* "presence": Presence updates.
* "typing": Typing updates.
* "receipts": Receipt updates.
* "user_account_data": Top-level per user account data.
* "room_account_data: Per room per user account data.
* "tag_account_data": Per room per user tags.
* "backfill": Old events that have been backfilled from other servers.
* "push_rules": Per user changes to push rules.
* "pushers": Per user changes to their pushers.
The API takes two additional query parameters:
* "timeout": How long to wait before returning an empty response.
* "limit": The maximum number of rows to return for the selected streams.
The response is a JSON object with keys for each stream with updates. Under
each key is a JSON object with:
* "position": The current position of the stream.
* "field_names": The names of the fields in each row.
* "rows": The updates as an array of arrays.
There are a number of ways this API could be used:
1) To replicate the contents of the backing database to another database.
2) To be notified when the contents of a shared backing database changes.
3) To "tail" the activity happening on a server for debugging.
In the first case the client would track all of the streams and store it's
own copy of the data.
In the second case the client might theoretically just be able to follow
the "streams" stream to track where the other streams are. However in
practise it will probably need to get the contents of the streams in
order to expire the any in-memory caches. Whether it gets the contents
of the streams from this replication API or directly from the backing
store is a matter of taste.
In the third case the client would use the "streams" stream to find what
streams are available and their current positions. Then it can start
long-polling this replication API for new data on those streams.
