* fix a typo in registration_shared_secret_path docs
Signed-off-by: Filip Rutar <filip.rutar@gmail.com>

* changelog

Note that this is only used for key-value store (cached values)
and not for the pub/sub replication used by Synapse.

Respond with a 405 error if a request is received on a known endpoint,
but to an unknown method, per MSC3743.

* Document how to run Synapse

* Changelog for 15022

* Update docs/development/contributing_guide.md

This PR just clarifies in the SRV DNS delegation document that there are
still cases a user may have to serve files from `.well-known` endpoints,
and this may not be a valid case for using SRV delegation. This has
caused some confusion in a few cases.

* Request partial joins by default

This is a little sloppy, but we are trying to gain confidence in faster
joins in the upcoming RC.

Admins can still opt out by adding the following to their Synapse
config:

```yaml
experimental:
    faster_joins: false
```

We may revert this change before the release proper, depending on how
testing in the wild goes.

* Changelog

* Try to fix the backfill test failures

* Upgrade notes

* Postgres compat?

You do not have to restart synapse to reload the log config.

* Change Documentation to have v10 as default room version

* Change Default Room version to 10

* Add changelog entry for default room version swap

* Add changelog entry for v10 default room version in docs

* Clarify doc changelog entry

* Upgrade to new lockfile format

Now requires poetry >= 1.2.2 to read and poetry >= 1.3.0 to write.

Cheat sheet:

```
poetry --version
poetry show > scratch/before
pipx upgrade poetry
poetry --version
poetry show > scratch/after
diff scratch{before,after} && echo "no change!"
```

* Use Poetry 1.3.2 when reading or writing lockfile

* Remove unneeded(?) poetry dep for cibuildwheel

* Update docs

* Remove redundant call to setup-python

* Remove outdated comments related to Poetry 1.x

* Remove outdated docs line

was fixed in #13082

* Minor improvements to poetry cheat sheet

* Invoke setup-python-poetry with explicit version

Not sure about this. It's hardcoding versions everywhere.

* Changelog

* Check the lockfile is version 2.0

Might one day incorporate other checks like #14742

* Typo fixes, thanks Sean

* Fix missing field in AS documentation

The [AS Configuration Snippet](https://matrix-org.github.io/synapse/latest/application_services.html) is missing `id` field, without it Synapse will fail to load:

This also alphabetizes the documentation for the various OpenID providers.

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.
