Synapse 0.99.1 (2019-02-14)
===========================

Features
--------

- Include m.room.encryption on invites by default ([\#3902](https://github.com/matrix-org/synapse/issues/3902))
- Federation OpenID listener resource can now be activated even if federation is disabled ([\#4420](https://github.com/matrix-org/synapse/issues/4420))
- Synapse's ACME support will now correctly reprovision a certificate that approaches its expiry while Synapse is running. ([\#4522](https://github.com/matrix-org/synapse/issues/4522))
- Add ability to update backup versions ([\#4580](https://github.com/matrix-org/synapse/issues/4580))
- Allow the "unavailable" presence status for /sync.
  This change makes Synapse compliant with r0.4.0 of the Client-Server specification. ([\#4592](https://github.com/matrix-org/synapse/issues/4592))
- There is no longer any need to specify `no_tls`: it is inferred from the absence of TLS listeners ([\#4613](https://github.com/matrix-org/synapse/issues/4613), [\#4615](https://github.com/matrix-org/synapse/issues/4615), [\#4617](https://github.com/matrix-org/synapse/issues/4617), [\#4636](https://github.com/matrix-org/synapse/issues/4636))
- The default configuration no longer requires TLS certificates. ([\#4614](https://github.com/matrix-org/synapse/issues/4614))

Bugfixes
--------

- Copy over room federation ability on room upgrade. ([\#4530](https://github.com/matrix-org/synapse/issues/4530))
- Fix noisy "twisted.internet.task.TaskStopped" errors in logs ([\#4546](https://github.com/matrix-org/synapse/issues/4546))
- Synapse is now tolerant of the `tls_fingerprints` option being None or not specified. ([\#4589](https://github.com/matrix-org/synapse/issues/4589))
- Fix 'no unique or exclusion constraint' error ([\#4591](https://github.com/matrix-org/synapse/issues/4591))
- Transfer Server ACLs on room upgrade. ([\#4608](https://github.com/matrix-org/synapse/issues/4608))
- Fix failure to start when not TLS certificate was given even if TLS was disabled. ([\#4618](https://github.com/matrix-org/synapse/issues/4618))
- Fix self-signed cert notice from generate-config. ([\#4625](https://github.com/matrix-org/synapse/issues/4625))
- Fix performance of `user_ips` table deduplication background update ([\#4626](https://github.com/matrix-org/synapse/issues/4626), [\#4627](https://github.com/matrix-org/synapse/issues/4627))

Internal Changes
----------------

- Change the user directory state query to use a filtered call to the db instead of a generic one. ([\#4462](https://github.com/matrix-org/synapse/issues/4462))
- Reject federation transactions if they include more than 50 PDUs or 100 EDUs. ([\#4513](https://github.com/matrix-org/synapse/issues/4513))
- Reduce duplication of ``synapse.app`` code. ([\#4567](https://github.com/matrix-org/synapse/issues/4567))
- Fix docker upload job to push -py2 images. ([\#4576](https://github.com/matrix-org/synapse/issues/4576))
- Add port configuration information to ACME instructions. ([\#4578](https://github.com/matrix-org/synapse/issues/4578))
- Update MSC1711 FAQ to calrify .well-known usage ([\#4584](https://github.com/matrix-org/synapse/issues/4584))
- Clean up default listener configuration ([\#4586](https://github.com/matrix-org/synapse/issues/4586))
- Clarifications for reverse proxy docs ([\#4607](https://github.com/matrix-org/synapse/issues/4607))
- Move ClientTLSOptionsFactory init out of `refresh_certificates` ([\#4611](https://github.com/matrix-org/synapse/issues/4611))
- Fail cleanly if listener config lacks a 'port' ([\#4616](https://github.com/matrix-org/synapse/issues/4616))
- Remove redundant entries from docker config ([\#4619](https://github.com/matrix-org/synapse/issues/4619))
- README updates ([\#4621](https://github.com/matrix-org/synapse/issues/4621))
