v1.3.4

Added

• Dendrite homeservers can now have their media imported safely, and adminApiKind may be set to dendrite.
• Exporting MMR's data to Synapse is now possible with import_to_synapse. To use it, first run gdpr_export or similar.
• Errors encountered during a background task, such as an API-induced export, are exposed as error_message in the admin API.
• MMR will follow redirects on federated downloads up to 5 hops.
• S3-backed datastores can have download requests redirected to a public-facing CDN rather than being proxied through MMR. See publicBaseUrl under the S3 datastore config.

Changed

• Exports now use an internal timeout of 10 minutes instead of 1 minute when downloading files. This may still result in errors if downloading from S3 takes too long.
• MMR now requires Go 1.21 for compilation.
• ARM-supported Docker images are now available through GHCR.
  • The Docker Hub (docker.io) builds are deprecated and will not receive updates starting with v1.4.0
  • Docker Hub images are not guaranteed to have ARM compatibility.
• The latest Docker tag on both Docker Hub and GHCR now points to the latest release instead of the unstable development build.

Fixed

• Exports created with s3_urls now contain valid URLs.
• Exports no longer fail with "The requested range is not satisfiable".
• Exports no longer fail with "index out of range [0] with length 0".
• Requests requiring authentication, but lack a provided access token, will return HTTP 401 instead of HTTP 500 now.
• Downloads when using a self-hosted MinIO instance are no longer slower than expected.
• The DELETE /_matrix/media/unstable/admin/export/:exportId endpoint has been reinstated as described.
• If a server's downloads.maxSize is greater than the uploads.maxSize, remote media is no longer cut off at uploads.maxSize. The media will instead be downloaded at downloads.maxSize and error if greater.
• Content-Type on /download and /thumbnail is now brought in line with MSC2701.
