Upgrading to v0.34.0
|
||||
====================
|
||||
|
||||
This release removes the ``riot.im`` from the default list of trusted identity servers.
|
||||
1. This release is the first to fully support Python 3. We recommend switching
|
||||
to Python 3, as it has been shown to give performance improvements.
|
||||
|
||||
For users who have installed Synapse into a virtualenv, we recommend doing
|
||||
this by creating a new virtualenv. For example::
|
||||
|
||||
virtualenv -p python3 ~/synapse/env3
|
||||
source ~/synapse/env3/bin/activate
|
||||
pip install matrix-synapse
|
||||
|
||||
You can then start synapse as normal, having activated the new virtualenv::
|
||||
|
||||
cd ~/synapse
|
||||
source env3/bin/activate
|
||||
synctl start
|
||||
|
||||
Users who have installed from distribution packages should see the relevant
|
||||
package documentation.
|
||||
|
||||
* When upgrading to Python 3, you **must** make sure that your log files are
|
||||
configured as UTF-8, by adding ``encoding: utf8`` to the
|
||||
``RotatingFileHandler`` configuration (if you have one) in your
|
||||
``<server>.log.config`` file. For example, if your ``log.config`` file
|
||||
contains::
|
||||
|
||||
handlers:
|
||||
file:
|
||||
class: logging.handlers.RotatingFileHandler
|
||||
formatter: precise
|
||||
filename: homeserver.log
|
||||
maxBytes: 104857600
|
||||
backupCount: 10
|
||||
filters: [context]
|
||||
console:
|
||||
class: logging.StreamHandler
|
||||
formatter: precise
|
||||
filters: [context]
|
||||
|
||||
Then you should update this to be::
|
||||
|
||||
handlers:
|
||||
file:
|
||||
class: logging.handlers.RotatingFileHandler
|
||||
formatter: precise
|
||||
filename: homeserver.log
|
||||
maxBytes: 104857600
|
||||
backupCount: 10
|
||||
filters: [context]
|
||||
encoding: utf8
|
||||
console:
|
||||
class: logging.StreamHandler
|
||||
formatter: precise
|
||||
filters: [context]
|
||||
|
||||
There is no need to revert this change if downgrading to Python 2.
|
||||
|
||||
2. This release removes the ``riot.im`` from the default list of trusted
|
||||
identity servers.
|
||||
|
||||
If ``riot.im`` is in your homeserver's list of
|
||||
``trusted_third_party_id_servers``, you should remove it. It was added in
|
||||
case a hypothetical future identity server was put there. If you don't
|
||||
remove it, users may be unable to deactivate their accounts.
