ROOT vs Glances
A side-by-side editorial comparison of ROOT and Glances — release velocity, themes, recent moves, and the top alternatives to consider.
ROOT vs Glances: at a glance
What is ROOT?
ROOT 6.42 rebuilds its Python interface on cppjit and moves Cling to LLVM 22.
CERN's ROOT has published the first release candidate of 6.42.00, with the final scheduled for the end of November 2026. The release notes name two large changes: Cling, ROOT's C++ interpreter, moves to LLVM 22, and the Python interface is completely overhauled to rely on cppjit, which the team says brings more functionality, better runtime performance and simpler code. More than 180 tracker items were addressed. Until now the feed had been 6.40 LTS patches and backports to older series.
What is Glances?
Glances 4.5.9 closes out the 4.x line as a 5.0 beta opens for testing.
Glances 4.5.9 replaces the python-jose library, which carried a CVE, with PyJWT and updates every dependency. The notes say it is the last 4.x release and point users to a Glances 5.0.0 beta on Test PyPI and a dev Docker image. Most 4.5 releases this year were security and correctness fixes.

◆ Current state
CERN's ROOT has published the first release candidate of 6.42.00, with the final scheduled for the end of November 2026. The release notes name two large changes: Cling, ROOT's C++ interpreter, moves to LLVM 22, and the Python interface is completely overhauled to rely on cppjit, which the team says brings more functionality, better runtime performance and simpler code. More than 180 tracker items were addressed. Until now the feed had been 6.40 LTS patches and backports to older series.
◆ Where it's heading
After a stretch of LTS maintenance, 6.42 is a foundational release: the interpreter and the Python bindings are the two layers most analysis code runs through. Replacing the PyROOT machinery is the change most users will notice, since much HEP analysis is now written in Python. The older series keep receiving patches, so 6.40 LTS users won't be forced to move.
◆ Prediction
The release candidate exists to test these changes, so expect further rc builds or a 6.42.00 final around the end of November, with Python-interface fixes the most likely content of the first 6.42 patches.
Glances
5.0ANALYTICS
Glances 4.5.9 closes out the 4.x line as a 5.0 beta opens for testing.
◆ Current state
Glances 4.5.9 replaces the python-jose library, which carried a CVE, with PyJWT and updates every dependency. The notes say it is the last 4.x release and point users to a Glances 5.0.0 beta on Test PyPI and a dev Docker image. Most 4.5 releases this year were security and correctness fixes.
◆ Where it's heading
After a year of CVE patches and alert correctness work on 4.5, the project is ending the 4.x line and moving to 5.0. The feed does not yet describe what changes in 5.0.
◆ Prediction
Expect further 5.0 betas and then a 5.0.0 release; whether it changes the plugin model, web UI or API is not visible in these entries.
