Changes in synapse v0.8.0 (2015-03-06)
======================================
General:
* Add support for registration fallback. This is a page hosted on the server
which allows a user to register for an account, regardless of what client
they are using (e.g. mobile devices).
* Added new default push rules and made them configurable by clients:
* Suppress all notice messages.
* Notify when invited to a new room.
* Notify for messages that don't match any rule.
* Notify on incoming call.
Federation:
* Added per host server side rate-limiting of incoming federation requests.
* Added a ``/get_missing_events/`` API to federation to reduce number of
``/events/`` requests.
Configuration:
* Added configuration option to disable registration:
``disable_registration``.
* Added configuration option to change soft limit of number of open file
descriptors: ``soft_file_limit``.
* Make ``tls_private_key_path`` optional when running with ``no_tls``.
Application services:
* Application services can now poll on the CS API ``/events`` for their events,
by providing their application service ``access_token``.
* Added exclusive namespace support to application services API.
Changes in synapse v0.7.1 (2015-02-19)
======================================
* Initial alpha implementation of parts of the Application Services API.
Including:
- AS Registration / Unregistration
- User Query API
- Room Alias Query API
- Push transport for receiving events.
- User/Alias namespace admin control
* Add cache when fetching events from remote servers to stop repeatedly
fetching events with bad signatures.
* Respect the per remote server retry scheme when fetching both events and
server keys to reduce the number of times we send requests to dead servers.
* Inform remote servers when the local server fails to handle a received event.
* Turn off python bytecode generation due to problems experienced when
upgrading from previous versions.
Changes in synapse v0.7.0 (2015-02-12)
======================================
* Add initial implementation of the query auth federation API, allowing
servers to agree on whether an event should be allowed or rejected.
* Persist events we have rejected from federation, fixing the bug where
servers would keep requesting the same events.
* Various federation performance improvements, including:
- Add in memory caches on queries such as:
* Computing the state of a room at a point in time, used for
authorization on federation requests.
* Fetching events from the database.
* User's room membership, used for authorizing presence updates.
- Upgraded JSON library to improve parsing and serialisation speeds.
* Add default avatars to new user accounts using pydenticon library.
* Correctly time out federation requests.
* Retry federation requests against different servers.
* Add support for push and push rules.
* Add alpha versions of proposed new CSv2 APIs, including ``/sync`` API.
Changes in synapse 0.6.1 (2015-01-07)

On OSX, if you encounter clang: error: unknown argument: '-mno-fused-madd' you
will need to export CFLAGS=-Qunused-arguments.
ArchLinux
---------
Installation on ArchLinux may encounter a few hiccups as Arch defaults to
python 3, but synapse currently assumes python 2.7 by default.
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 )::
$ sudo pip2.7 install --upgrade pip

request::

compile it under the right architecture. (This should not be needed if
installing under virtualenv)::

During setup of homeserver you need to call python2.7 directly again::

Troubleshooting Running
-----------------------
If ``synctl`` fails with ``pkg_resources.DistributionNotFound`` errors you may
need a newer version of setuptools than that provided by your OS.::
$ sudo pip install setuptools --upgrade
If synapse fails with ``missing "sodium.h"`` crypto errors, you may need
to manually upgrade PyNaCL, as synapse uses NaCl (http://nacl.cr.yp.to/) for

Upgrading to v0.8.0
===================
Servers which use captchas will need to add their public key to::
static/client/register/register_config.js
window.matrixRegistrationConfig = {
recaptcha_public_key: "YOUR_PUBLIC_KEY"
};
This is required in order to support registration fallback (typically used on
mobile devices).
Upgrading to v0.7.0
===================
New dependencies are:
- pydenticon
- simplejson
- syutil
- matrix-angular-sdk
To pull in these dependencies in a virtual env, run::
python synapse/python_dependencies.py | xargs -n 1 pip install
