KDE: Update KDE Plasma Desktop to 5.26

All About the Widgets

Plasma 5.26 comes with new and tweaked widgets, improves the desktop
experience leaps and bounds, and Plasma Big Screen's app family grows

Tuesday, 11 October 2022

Even with a bare-bones installation, Plasma lets you customize your
desktop a lot. If you want more, there is always Plasma’s vast ecosystem
of widgets. Widgets add features and utilities to the Plasma desktop and
today you can find out all the stuff you can do and what’s new for
widgets in Plasma 5.26.

Widgets are not the only thing to look forward to in Plasma 5.26: check
out all the new stuff landing on the desktop designed to make using
Plasma easier, more accessible and enjoyable, as well as the two new
utilities for Plasma Big Screen, KDE’s interface for smart TVs.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

KDE: Update KDE Plasma Desktop to 5.23

Thursday, 14 October 2021

   25 years ago today, Matthias Ettrich sent an email to the
   de.comp.os.linux.misc newsgroup explaining a project he was working
   on. The latest and direct result of that email (plus a quarter of a
   century of relentless experimentation, development and innovation)
   has just landed in KDE’s repositories.

   This time around, Plasma renews its looks and, not only do you get a
   new wallpaper, but also a gust of fresh air from an updated theme:
   Breeze - Blue Ocean. The new Breeze theme makes KDE apps and tools
   not only more attractive, but also easier to use both on the desktop
   and your phone and tablet.

Update KDE Plasma Desktop to 5.20.0

Everyday utilities and tools, such as the Panels, Task Manager, Notifications
and System Settings, have all been overhauled to make them more usable,
efficient, and friendlier.

Meanwhile, developers are hard at work adapting Plasma and all its bits and
pieces to Wayland. Once done, Plasma will not only be readier for the future,
but will also work better with touchscreens and multiple screens with different
refresh rates and DPIs. Plasma will also offer better support for
hardware-accelerated graphics, be more secure, and enjoy many more advantages.
Although still work in progress, 5.20 already offers users many of the benefits
of Plasma on Wayland.
