    Notes in addition to the information in the attached documents

    Input required for EP R&D Projects
    Discussions held 9th - 16th September (to be confirmed)
    Current:
    - Interoperability
    - Acceleration
    - Analysis facilities

    Probably 3 years duration

    Jakob: timelines compared to hardware R&D is different that is something that we will need to explain.
    JonasH: too early to talk about ROOT 8
    Danilo: just a placeholder to introduce new features
    Lukas: Perhaps call it ROOT R&D to combine projects that are more forward looking and were we don't know yet if they will lead to a feature

    Regarding the decline in user posts
    Jakob: We are loosing the ability to learn about the issues of our users. We may need other ways of getting this information.
    JonasH: When do we need to get worried that we loose our 2nd place in terms of forum popularity at CERN (behind the CERN Marketplace)? Let's compare with Geant forum, if they see the same trend.

    @ releas:
    Nobody objected to locking the 6.40 branch

    Meeting Summaries

    IO: round table
    Statistical analysis: not yet resumed
    PPP: no meeting
    Python-Cpp: dropping llvm as dependency -> self-contained wheel
    Planning/Stakeholders: no meeting
    LIM: one of the stacks build failed. symlink related - should be fixed already

    Sergey will visit 14th of September for one week

    Philippe discussion on the default for builtin / dependence when you call cmake
    cmake should not edit the CMakeCache. For the builtin that can be provided, but are not found on the system, we don't turn them on. -> They need to explicitly ask for it? 6.42

    regarding win32gdk
    Bertrand: win32gdk has been heavily modified. taking it from somewhere else will not work. More than 20 years old. Will take a look.
    Jakob: How does this relate to Serguey's work.
    Answer: Sergey is working on graphics, Bertrand on GUI

    regarding hosting builtins
    Sergey: better to rely on infrastructure that we can rely on and that also works in 10y.

    Aaron reports no blockers
    Bertrand: did you fix the windows issue?
    Aaron: API need to be reworked for it? Do not annotate the class. Only annotate the members.
