+## [0.27.0] - 2022-02-13
+
+This is a fairly small release, primarily to bump substrate dependencies to their latest versions.
+
+The main breaking change is fairly small: [#804](https://github.com/paritytech/subxt/pull/804). Here, the `BlockNumber` associated type has been removed from `Config` entirely, since it wasn't actually needed anywhere in Subxt. Additionally, the constraints on each of those associated types in `Config` were made more precise, primarily to tidy things up (but this should result in types more easily being able to meet the requirements here). If you use custom `Config`, the fix is simply to remove the `BlockNumber` type. If you also use the `Config` trait in your own functions and depend on those constraints, you may be able to define a custom `MyConfig` type which builds off `Config` and adds back any additional bounds that you want.
+
+Note worthy PRs merged since the last release:
