# Continuwuity 0.5.10 (2026-06-20)

## Security

# Continuwuity 0.5.9 (2026-05-07)

## Security

- Fixed a bug that caused the server to drop events during processing if several events for the same room were sent in a
  singular transaction. Contributed by @nex. (#1711)
- Fixed a bug that caused the server to panic while handling transactions with malformed events, resulting in a
  deadlock that prevented the remote server from federating with us until the server was restarted. Contributed by @nex.
- Fixed a bug that resulted in the `m.federate` field of `m.room.create` being ignored in v12 rooms, allowing remote
  servers to participate in local-only rooms. Contributed by @nex, reported
  by [@mat:emzee.ee](matrix:u/mat:emzee.ee?action=chat).

# Continuwuity 0.5.8 (2026-04-24)

  Contributed by @Jade.
- Fixed data amplification vulnerability (CWE-409) that affected configurations with server-side compression enabled (
  non-default). Contributed by @nex.

## Features

- Outgoing presence is now disabled by default, and the config option documentation has been adjusted to more accurately

  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))

  line. ([#1394](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1394))

  @nex ([#1393](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1393))

  @0xnim. ([#1441](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1441))

  returned. Contributed by @0xnim ([#1445](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1445))
- 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.

- Refuse to process requests for and events in rooms that we no longer have any local users in (reduces state resets
  and improves performance). Contributed by
  @nex ([#1316](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1316))
- Added server-specific admin API routes to ban and unban rooms, for use with moderation bots. Contributed by @nex

  Contributed by @nex, reported by violet & [mat](https://matdoes.dev).
- ACLs are no longer case-sensitive. Contributed by @nex, reported by [vel](matrix:u/vel:nhjkl.com?action=chat).

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

  superseded by this feature and **has been removed**. Use the new `!admin token` command family to manage registration
  tokens. Contributed by @ginger (#783).
