## New and Noteworthy

### UX improvements

[Bug 62179](https://bz.apache.org/bugzilla/show_bug.cgi?id=62179)[Bug 64658](https://bz.apache.org/bugzilla/show_bug.cgi?id=64658)The splash screen is now application-modal rather than system-modal, so it does not block other
applications when JMeter is starting up.

## Incompatible changes

- Remove LogKit logger functionality from some classes. This was intended to completely remove       `LoggingManager` class (it has been deprecated since JMeter 3.2), but as jmeter-plugins       depended on it, `LoggingManager` and our `LogKit`-adapter will remain for       this version (but is still deprecated).
