ChangeLog for hotspot v1.5.0

The hotspot v1.5.0 release is finally here :tada:

It comes packed with a wealth of code cleanups, bug fixes and new functionality. Most notably, the disassembly view has been further improved with better searching, highlighting and faster performance.

Furthermore, we reworked the authentication mechanism to allow perf record get run directly with elevated priveleges via pkexec, obsoleting the error prone old mechanism (see also https://nvd.nist.gov/vuln/detail/CVE-2023-28144).

We now also fully support Qt6 and KF6, while keeping compatibility with Qt5 and KF5. The AppImage below is still build with Qt5 but it might be the last time that we do this. The next version might become Qt6 only.

Many thanks to the various contributors that help build this software, both by writing code as well as reporting bugs.

Happy profiling everyone :rocket:

NOTE: GitHub does not allow me to upload the AppImage directly anymore, you need to gunzip the compressed AppImage.gz first :shrug:
