 ## 7.14.2 (April 7th 2023)
 This release is the first to includes various bug fixes and optimizations thanks to running much of the code through [Chat GPT-4](https://openai.com/product/gpt-4), most of which are not explicitly listed in the [CHANGELOG](https://github.com/rqlite/rqlite/edit/master/CHANGELOG.md), but you can check the commit history for details. Future releases of rqlite will probably include more such changes.
