Dendrite 0.3.0 released

Hi all,

Heads up that we just cut another beta release of Dendrite - now at 0.3.0!

This is a really fun release given almost all the changes are contributed from the wider community - so huge thanks to S7evinK, MayeulC and felix!

The main new feature is full Read Receipt support thanks to S7evinK, which makes an enormous perceptual improvement when using Dendrite - so especial thanks are due there :)

So, if you're interested in helping us test, please spin up a copy from https://github.com/matrix-org/dendrite and let us know how it goes - and if you're already running one, now is an excellent time to upgrade!

Full changelog (including 0.2.1, which we forgot to blog about) follows:

🔗Dendrite 0.3.0 (2020-11-16)

🔗Features

• Read receipts (both inbound and outbound) are now supported (contributed by S7evinK)
• Forgetting rooms is now supported (contributed by S7evinK)
• The -version command line flag has been added (contributed by S7evinK)

🔗Fixes

• Some more client event fields have been marked as omit-when-empty (contributed by S7evinK)

🔗Dendrite 0.2.1 (2020-10-22)

🔗Fixes

• Forward extremities are now calculated using only references from other extremities, rather than including outliers, which should fix cases where state can become corrupted (#1556)
• Old state events will no longer be processed by the sync API as new, which should fix some cases where clients incorrectly believe they have joined or left rooms (#1548)
• More SQLite database locking issues have been resolved in the latest events updater (#1554)
• Internal HTTP API calls are now made using H2C (HTTP/2) in polylith mode, mitigating some potential head-of-line blocking issues (#1541)
• Roomserver output events no longer incorrectly flag state rewrites (#1557)
• Notification levels are now parsed correctly in power level events (gomatrixserverlib#228, contributed by Pestdoktor)
• Invalid UTF-8 is now correctly rejected when making federation requests (gomatrixserverlib#229, contributed by Pestdoktor)
