v1.5.0

ChangeLog for hotspot v1.5.0

The hotspot v1.5.0 release is finally here 🎉

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 🚀

Full Changelog: v1.4.1...v1.5.0

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

This discussion was created from the release v1.5.0.

[GitMensch]

Can you please add the debuginfo matching the appimage as well?

[milianw]

Thanks - done. I forgot that, and since I lost the debuginfo from yesterday I had to rebuild the appimage. You will need to download the new one too if you want to have matching debuginfo - our build isn't reproducible it seems.

[GitMensch]

Thanks a lot!

[GitMensch]

Do you plan to write an article or a blog entry about this release (like you did for 1.3.0 and 1.4.0 - or Hoptspot in general, soon?
I'd like to write a LinkedIn post (or an article, but I'm not sure to find the time for that anytime soon) about this software as I find it extremely useful, and would take the opportunity to post some links within that.

And - of course - an updated version of https://www.kdab.com/hotspot-video/ would be marvelous!

[milianw]

Yes there will be a blog post, probably released later today on our website.

What part would you like to see updated in the video?

[GitMensch]

The whole feature set of perf annotate (apart from #528 and possibly #607) got integrated nicely in the meanwhile and at least to me is a real important feature [as well as the callgraph-view (even if it isn't available in the appimage)].
Also the summary is improved and includes the hotspots by binary (which for example allows to quickly exclude "external" binaries from the view [both multi-program and library related]).
