Currently testing upgrade locally, if successful (or resolving issues)
I will upgrade jogamp.org this week.

This post was updated on .
Notable for dovecot:
- use `doveconf -a` to dump all config values
- use `doveconf -n` to dump only non-default config values, i.e. manually changed

My local conversion was successful and I upgrade jogamp.org now.
Therefore services might be interrupted until done.

Edit: a bit more color ...
- besides dovecot, only the php8.4 update required manual config intervention (webserver)
- locally, I had to purge a lot of my old gcc/clang packed selections, all smooth
- as laid out here, gcc 14 and clang-19 provides excellent support for C++20 and C++23 (almost)
- performance on AMD Ryzen seems to be improved, also Mesa 25 (OpenGL, vaapi, ..)
- openjdk 21 and 25 is supported
- zfs 2.3.2 is compatible w/ used Linux kernel 6.12 (up to 6.14)
  - will update soon

In case you use KDE plasma6 like me, here is my konsole-tab.css,
which reduces the tab-size in konsole (default is way too big).
(konsole -> settings -> Tab Bar / Splitters -> Use user-defined stylesheet)
- https://docs.kde.org/stable5/en/konsole/konsole/tabbarstylsheet.html
- https://doc.qt.io/qt-6/stylesheet.html
- https://doc.qt.io/qt-6/stylesheet-reference.html

QTabBar::tab::selected {
    background: #999999;
}
QTabBar::tab {
    font-size: 10px;
    min-height: 22px;
    max-height: 22px;
    min-width: 60px;
    max-width: 60px;
    padding: 0;
    margin: 0;
    border: 0;
    text-align: left;
}
+++

Note: Last 2 days we have experienced another high server load
and I was forced to reset the machine thrice.
I have reduced the apache-bugzilla resources (almost halved).

OK, all running AFAIK but Jenkins (will update when doing next release).

Also updated our server setup docs a little, see https://jogamp.org/cgit/jogamp-scripting.git/log/.

Let's see how good it performs.
