- Added [MSC3814](https://github.com/matrix-org/matrix-spec-proposals/pull/3814) Dehydrated Devices - you can now decrypt messages sent while all devices were logged out. ([#1436](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1436))
- Implement [MSC4143](https://github.com/matrix-org/matrix-spec-proposals/pull/4143) MatrixRTC transport discovery endpoint. Move RTC foci configuration from `[global.well_known]` to a new `[global.matrix_rtc]` section with a `foci` field. Contributed by @0xnim ([#1442](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1442))

- Fixed a bug that (repairably) caused a room split between continuwuity and non-continuwuity servers when the room had both `m.room.policy` and `org.matrix.msc4284.policy` in its room state. Contributed by @nex ([#1481](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1481))

  rejected. Contributed by @trashpanda ([#1372](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1372))
- Improved the first-time setup experience for new homeserver administrators:
    - Account registration is disabled on the first run, except for with a new special registration token that is logged
      to the console.
    - Other helpful information is logged to the console as well, including a giant warning if open registration is
      enabled.
    - The default index page now says to check the console for setup instructions if no accounts have been created.
    - Once the first admin account is created, an improved welcome message is sent to the admin room.

  Contributed by @ginger.

## Bugfixes

- Fixed invites sent to other users in the same homeserver not being properly sent down sync. Users with missing or
  broken invites should clear their client caches after updating to make them appear. ([#1249](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1249))
- LDAP-enabled servers will no longer have all admins demoted when LDAP-controlled admins are not configured.

  registration token hardcoded in the config file. These tokens may optionally expire after a certain number of uses or
