 --------
 
 - Fix a bug where federation requests would fail early if a `.well-known/matrix/server` response contains an invalid type for `m.server`. Instead, try finding an SRV record, as mandated by [the spec](https://spec.matrix.org/v1.1/server-server-api/#resolving-server-names). ([\#473](https://github.com/matrix-org/sydent/issues/473))
-- Fix bug in the casefolding script that would cause some deletions to be skipped if e-mail sending was enabled. ([\#489](https://github.com/matrix-org/sydent/issues/489))
-- Fix a bug introduced in Sydent 2.4.6 where errors communicating with openmarket would be logged as successes, and all successes would be logged twice. ([\#490](https://github.com/matrix-org/sydent/issues/490))
