### New features

### Enhancements
- Rename the camera profiling file to make the timestamp of the profiling files readable. ([#434](https://github.com/KindlingProject/kindling/pull/434))
- When using the file writer in `cameraexporter`, we rotate files in chronological order now and rotate half of files one time. ([#420](https://github.com/KindlingProject/kindling/pull/420))
- Support to identify the MySQL protocol with statements `commit` and `set`. ([#417](https://github.com/KindlingProject/kindling/pull/417))
