Hotspot v1.5.0 released The Linux perf GUI for Performance Analysis

Hotspot is a standalone GUI designed to provide a user-friendly interface for analyzing performance data. It takes a file, parses and evaluates its contents, and presents the results in a visually appealing and easily understandable manner. Our goal with Hotspot is to offer a modern alternative to perf report, making performance analysis on Linux systems more intuitive and efficient.

We now also fully support Qt6 and KF6, while keeping compatibility with Qt5 and KF5. The AppImage below is still built 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 who help build this software, both by writing code as well as reporting bugs.
