Deprecation Policy for Platform Dependencies
|
|
|
|
|
============================================
|
|
|
|
|
|
|
|
|
|
Synapse has a number of platform dependencies, including Python and PostgreSQL.
|
|
|
|
|
This document outlines the policy towards which versions we support, and when we
|
|
|
|
|
drop support for versions in the future.

Policy
|
|
|
|
|
------
|
|
|
|
|
|
|
|
|
|
Synapse follows the upstream support life cycles for Python and PostgreSQL,
|
|
|
|
|
i.e. when a version reaches End of Life Synapse will withdraw support for that
|
|
|
|
|
version in future releases.
|
|
|
|
|
|
|
|
|
|
Details on the upstream support life cycles for Python and PostgreSQL are

|
|
|
documented at [https://endoflife.date/python](https://endoflife.date/python) and
|
|
|
|
|
[https://endoflife.date/postgresql](https://endoflife.date/postgresql).

Context
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
It is important for system admins to have a clear understanding of the platform
|
|
|
|
|
requirements of Synapse and its deprecation policies so that they can
|
|
|
|
|
effectively plan upgrading their infrastructure ahead of time. This is
|
|
|
|
|
especially important in contexts where upgrading the infrastructure requires
|
|
|
|
|
auditing and approval from a security team, or where otherwise upgrading is a
|
|
|
|
|
long process.
|
|
|
|
|
|
|
|
|
|
By following the upstream support life cycles Synapse can ensure that its
|
|
|
|
|
dependencies continue to get security patches, while not requiring system admins
|
|
|
|
|
to constantly update their platform dependencies to the latest versions.
