PKCE can protect against certain attacks and is enabled by default. Support
can be controlled manually by setting the pkce_method of each oidc_providers
entry to 'auto' (default), 'always', or 'never'.

This is required by Twitter OAuth 2.0 support.

OpenID specifies the format of the user info endpoint and some
OAuth 2.0 IdPs do not follow it, e.g. NextCloud and Twitter.

This adds subject_template and picture_template options to the
default mapping provider for more flexibility in matching those user
info responses.

* Move `email` to server in config file documentation

* changelog

Fix `target_memory_usage` being used in the description for the actual `cache_autotune` sub-option `target_cache_memory_usage`.

Disable legacy Prometheus metric names by default. They can still be re-enabled for now, but they will be removed altogether in Synapse 1.73.0. (#14353)

Synapse when they log out of the identity provider.

The IdP sends a request directly to Synapse (and must be
configured with an endpoint) when a user logs out.

      x_forwarded: true
