OpenBSD KDE Status Report
|
| |
OpenBSD has managed to drop KDE3 and KDE4 in the 6.8 -> 6.9 release cycle. That makes me very happy because it was a big piece of work and long discussions. This of course brings questions: Kde Plasma 5 package missing. After half a year of work, I managed to successfully update the Qt5 stack to the last LTS version 5.15.2. On the whole, the most work was updating QtWebengine.

However, your syspatch may fail if your local mirror uses a Let's Encrypt ...
