ROOT vs OpenPanel: at a glance
What is ROOT?
ROOT 6.40 LTS patches CMake 4.4 compatibility and 25+ tracked issues in one drop.
ROOT 6.40 LTS is in active patch maintenance. The 6.40.04 update fixed a CMake 4.4 compatibility break that was blocking new builds, alongside 25+ tracked issues spanning NTuple late-extension bugs, RooFit integral correctness, GDML geometry parsing, and Minuit2 robustness. Multiple older series — 6.36, 6.32, 6.30, 6.28 — continue receiving minor patches, reflecting the long support windows typical of HEP infrastructure software.
What is OpenPanel?
OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.
OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.
ROOT vs OpenPanel: editorial side-by-side
ROOT
5.0ANALYTICS
ROOT 6.40 LTS patches CMake 4.4 compatibility and 25+ tracked issues in one drop.
◆ Current state
ROOT 6.40 LTS is in active patch maintenance. The 6.40.04 update fixed a CMake 4.4 compatibility break that was blocking new builds, alongside 25+ tracked issues spanning NTuple late-extension bugs, RooFit integral correctness, GDML geometry parsing, and Minuit2 robustness. Multiple older series — 6.36, 6.32, 6.30, 6.28 — continue receiving minor patches, reflecting the long support windows typical of HEP infrastructure software.
◆ Where it's heading
The 6.40 LTS capabilities — concurrent histogram filling, RDataLoader, S3/libcurl-backed I/O, experimental opt-out of auto-registration — shipped in 6.40.00 and the patch cycle is now focused on correctness and compatibility. ROOT 7's full-API future continues to be a long-horizon goal; in the near term, the project is consolidating the 6.40 LTS base.
◆ Prediction
Expect continued 6.40.x patches at this cadence, with occasional older-series backports. A 6.42 development series will eventually surface new capabilities, but there is no visible signal of its timeline from the current patch activity.
OpenPanel
5.0ANALYTICS
OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.
◆ Current state
OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.
◆ Where it's heading
The 3.x line has climbed from 3.0.0 to 3.16.4 in under two weeks, with each bump published as a bare build. The cadence shows active development, but the feed gives no way to see what changed or which builds matter.
◆ Prediction
Expect more note-free supporter builds; a public self-hosting release with notes is the first point where the content of 3.x becomes visible.
