- Admin escape commands received over federation will never be executed, as this is never valid in a genuine situation. 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 represent the weight of presence, typing indicators, and read receipts. Contributed by @nex. ([#1399](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1399))
- Improved the concurrency handling of federation transactions, vastly improving performance and reliability by more accurately handling inbound transactions and reducing the amount of repeated wasted work. Contributed by @nex and @Jade. ([#1428](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1428))
- Added [MSC3202](https://github.com/matrix-org/matrix-spec-proposals/pull/3202) Device masquerading (not all of MSC3202). This should fix issues with enabling [MSC4190](https://github.com/matrix-org/matrix-spec-proposals/pull/4190) for some Mautrix bridges. Contributed by @Jade ([#1435](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1435))
- 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))
- Updated `list-backups` admin command to output one backup per line. ([#1394](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1394))
- Improved URL preview fetching with a more compatible user agent for sites like YouTube Music. Added `!admin media delete-url-preview <url>` command to clear cached URL previews that were stuck and broken. ([#1434](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1434))
## Bugfixes
- Removed non-compliant nor functional room alias lookups over federation. Contributed by @nex ([#1393](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1393))
- Removed ability to set rocksdb as read only. Doing so would cause unintentional and buggy behaviour. Contributed by @Terryiscool160. ([#1418](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1418))
- Fixed a startup crash in the sender service if we can't detect the number of CPU cores, even if the `sender_workers` config option is set correctly. Contributed by @katie. ([#1421](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1421))
- Removed the `allow_public_room_directory_without_auth` config option. Contributed by @0xnim. ([#1441](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1441))
- Fixed sliding sync v5 list ranges always starting from 0, causing extra rooms to be unnecessarily processed and 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))
- Fixed `!admin media delete --mxc <url>` responding with an error message when the media was deleted successfully. Contributed by @lynxize
- Fixed spurious 404 media errors in the logs. Contributed by @benbot.
- Fixed spurious warn about needed backfill via federation for non-federated rooms. Contributed by @kraem.
- You can now set a custom User Agent for URL previews; the default one has been modified to be less likely to be
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.
Contributed by @Jade ([#1307](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1307))
- Fixed sliding sync not resolving wildcard state key requests, enabling Video/Audio calls in Element X. ([#1370](https://forgejo.ellis.link/continuwuation/continuwuity/pulls/1370))
