This release is an opportunity to try out the new functionalities of the 6.42.00 development release, currently scheduled for the end of November 2026. The new ROOT comes with many new features (see the preliminary release notes). These include two massive improvements: the upgrade of the LLVM version behind Cling to LLVM22, and the complete overhaul of ROOT's Python Interface, that now relies on cppjit. That means more functionality, runtime performance and simpler code.
Stability also improved: more than 180 items in the ROOT trackers have been addressed for this release.
