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)
=====================================
* Major optimizations to improve performance of initial sync and event sending
in large rooms (by up to 10x)
* Media repository now includes a Content-Length header on media downloads.
* Improve quality of thumbnails by changing resizing algorithm.

* Improve quality of thumbnails by changing resizing algorithm.
Changes in synapse 0.6.0 (2014-12-16)
=====================================
* Add new API for media upload and download that supports thumbnailing.
* Replicate media uploads over multiple homeservers so media is always served
to clients from their local homeserver. This obsoletes the
--content-addr parameter and confusion over accessing content directly
from remote homeservers.
* Implement exponential backoff when retrying federation requests when
sending to remote homeservers which are offline.
* Implement typing notifications.
* Fix bugs where we sent events with invalid signatures due to bugs where
we incorrectly persisted events.
* Improve performance of database queries involving retrieving events.

Changes in synapse 0.5.4a (2014-12-13)
======================================
* Fix bug while generating the error message when a file path specified in
the config doesn't exist.
* Fix bug while generating the error message when a file path specified in
the config doesn't exist.
Changes in synapse 0.5.4 (2014-12-03)
=====================================
* Fix presence bug where some rooms did not display presence updates for
remote users.
* Do not log SQL timing log lines when started with "-v"
* Fix potential memory leak.
* Fix presence bug where some rooms did not display presence updates for
remote users.
* Do not log SQL timing log lines when started with "-v"
* Fix potential memory leak.
Changes in synapse 0.5.3c (2014-12-02)
======================================
* Change the default value for the `content_addr` option to use the HTTP
listener, as by default the HTTPS listener will be using a self-signed
certificate.
* Change the default value for the `content_addr` option to use the HTTP
listener, as by default the HTTPS listener will be using a self-signed
certificate.
Changes in synapse 0.5.3 (2014-11-27)
=====================================
* Fix bug that caused joining a remote room to fail if a single event was not
signed correctly.
* Fix bug which caused servers to continuously try and fetch events from other
servers.
* Fix bug that caused joining a remote room to fail if a single event was not
signed correctly.

This installs synapse, along with the libraries it uses, into a virtual
environment under ``~/.synapse``.
Your python may not give priority to locally installed libraries over system
libraries, in which case you must add your local packages to your python path::
To set up your homeserver, run (in your virtualenv, as before)::
$ # on Linux:
$ export PYTHONPATH=$HOME/.local/lib/python2.7/site-packages:$PYTHONPATH
$ cd ~/.synapse

If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
$ rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
$ pip install --user twisted
$ pip install twisted
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
You also may need to explicitly specify python 2.7 again during the install
request::
$ pip2.7 install --process-dependency-links \
https://github.com/matrix-org/synapse/tarball/master
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv)::
$ sudo pip2.7 uninstall py-bcrypt
$ sudo pip2.7 install py-bcrypt
During setup of homeserver you need to call python2.7 directly again::
$ cd ~/.synapse
$ python2.7 -m synapse.app.homeserver \
--server-name machine.my.domain.name \
--config-path homeserver.yaml \
--generate-config

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
