Round Table

Danilo's update

Bertrand: Is the file upload issue fixed?
Danilo: should work, which reduces the manual work for the releases

Giacomo

Found a way to list files stored on eos

Jakob

Final presentation on RNTuple PSO. Still TODO: final report.
Stephan: regarding deprecation: removal should have longer time frames, because the community does not move that quickly
Jakob: waiting is associated with higher costs due to security
Jonas H: deprecation process should be written down to avoid repeated discussions

Koen

JonasR: the web-related things would also be interesting for the ROOT website: e.g., running a cpp interpreter in the website with WebAssembly
more discussions postponed to a later meeting

Philippe

CHEP and reviews

Stephan

Vincenzo: pointer check could be turned off completely in RDF
JonasH: even under the ROOT namespace
more discussions offline

AOB

Danilo: are there any PRs that should go into 6.40?
Silia: bug fix for data loader (does not have to go into 6.40)
Danilo: more critical, because there is an occasional test failure; so this would help ourselves

Vincenzo: regarding xrootd redirection on eos
Jakob: not so critical, can go into next patch release

JonasR: one RooFit fix

Wednesday decided as release date

Philippe: ROOT IO dev workshop in November 2026
