2.47.1

Needs a new make dependency: 'libxfce4windowing>=4.19.6' https://gitlab.xfce.org/xfce/xfce4-panel/-/blob/master/configure.ac?ref_type=heads#L22

This package now needs xfce4-dev-tools-git as the stable version is too old to build it.

Edit: It also has a runtime dependency on libxfce4windowing-git.

I was getting the following build error with this today:

checking for pkg-config... (cached) /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for libxfce4ui-2 >= 4.17.1... found, but 4.16.1
*** The required package libxfce4ui-2 was found on your system,
*** but the installed version (4.16.1) is too old.
*** Please upgrade libxfce4ui-2 to atleast version 4.17.1, or adjust
*** the PKG_CONFIG_PATH environment variable if you installed
*** the new version of the package in a nonstandard prefix so
*** pkg-config is able to find it.

To resolve this, I installed libxfce4ui-devel, not libxfce4ui-git. libxfce4ui-devel allowed the xfce4-panel-git build to succeed.

xfce4-panel has dropped gtk2 support hence the '--enable-gtk2' parameter should be removed from PKGBUILD.
