Dendrite only implements `/r0` of the CS API, and the legacy `/v1` endpoint had implementation errors which made it possible to bypass shared secret registration (thanks to Jakob Varmose Bentzen for reporting this) +* Attempting to register an account that already exists now returns a sensible error code rather than a HTTP 500 +* Dendrite will no longer attempt to `/make_join` with itself if listed in the request `server_names` +* `/sync` will no longer return immediately if there is nothing to sync, which happened particularly with new accounts, causing high CPU usage +* Malicious media uploads can no longer exhaust all available memory (contributed by [S7evinK](https://github.com/S7evinK)) +* Selecting one-time keys from the database has been optimised (contributed by [S7evinK](https://github.com/S7evinK)) +* The return code when trying to fetch missing account data has been fixed (contributed by [adamgreig](https://github.com/adamgreig)) +* Dendrite will no longer attempt to use `/make_leave` over federation when rejecting a local invite +* A panic has been fixed in `QueryMembershipsForRoom` +* A panic on duplicate membership events has been fixed in the federation sender +* A panic has been fixed in in `IsInterestedInRoomID` (contributed by [S7evinK](https://github.com/S7evinK)) +* A panic in the roomserver has been fixed when handling empty state sets +* A panic in the federation API has been fixed when handling cached events + ## Dendrite 0.3.11 (2021-03-02) ### Fixes diff --git a/internal/version.go b/internal/version.go index 0d348779..37f0c30d 100644 --- a/internal/version.go +++ b/internal/version.go @@ -16,8 +16,8 @@ var build string const ( VersionMajor = 0 - VersionMinor = 3 - VersionPatch = 11 + VersionMinor = 4 + VersionPatch = 0 VersionTag = "" // example: "rc1" ) |
