## 0.3.4
- Port [#693](https://github.com/yesodweb/persistent/pull/693) from `persistent-mysql`: Extend the `SomeField` type to allow `insertManyOnDuplicateKeyUpdate` to conditionally copy values.
- Port [#702](https://github.com/yesodweb/persistent/pull/702) from `persistent-mysql`: Fix behavior of `insertManyOnDuplicateKeyUpdate` to ignore duplicate key exceptions when no updates specified.
- Bumped TLS bounds to be in [sync with `mysql-haskell`](https://github.com/winterland1989/mysql-haskell/pull/15) and land ourselves [back on stackage](https://github.com/fpco/stackage/pull/2956).

- Exported [Data.TLSSetting](https://hackage.haskell.org/package/tcp-streams-1.0.0.0/docs/Data-TLSSetting.html) for convenient usage of TLS.
## 0.2.1.0
