+v1.15.0
+===
+
+This release comes 74 days (just over two months) since the last minor release.
+This mostly contains new features, with one relatively minor but important bug
+addressed (and one _very_ minor bug fixed).
+
+## Bug fixes
+
+* Fetch sessions now properly send forgotten topics if we forget the entire
+  topic (not just individual partitions while other partitions are still
+  consumed on the broker). For long-running clients where partitions move
+  around the cluster a bunch over time, this ensures we are not sending requests
+  with null topics / null topic IDs. See [#535](https://github.com/twmb/franz-go/issues/535)
+   for more details.
+* If the client talks to an http endpoint, we now properly detect the bytes
+  'HTTP' and send a more relevant error message. This previously existed, but
+  used the wrong int32 internally so 'HTTP' was not properly detected (thanks
+  [@alistairking](https://github.com/alistairking)!).
+
+## Features
+
+* `RecordReader` now supports %v{json} to parse json inputs
+* `RecordReader` now supports %v{}, an empty no-op formatting directive
+* Adds `PurgeTopicsFromProducing` and `PurgeTopicsFromConsuming` to purge _either_
+  the producing or consuming half of the client, if you are producing to and
+  consuming from the same topics in the same client.
+* The new `ConsiderMissingTopicDeletedAfter` option allows finer grained
+  control for how long a regexp-discovered topic can be missing on the cluster
+  before the topic is considered deleted (and then internally purged in the
+  client)
+* Adds `NewErrFetch` to create a single-error `Fetches`, for use in end-user
+  tests / stubs.
+* The new `MaxBufferedBytes` option can control how many bytes are buffered
+  when producing, an option similar to `MaxBufferedRecords`.
+* Adds `BufferedFetchBytes` and `BufferedProduceBytes` to return the total
+  bytes in records buffered (note this counts only keys, values, and headers).
+* Adds `PreTxnCommitFnContext` to allow custom `Metadata` annotation for
+  transactional commits.
+* Adds `LeaveGroupContext` to control how long leaving a group can take, as
+  well as to return any leave group error.
