OK. What is the process to create the announcement text? I noticed
that the ANNOUNCE file is still for 2.4.4, and status.24x is up to
date, but does not contain the top most part of ANNOUNCE (where the
python compatibility change should go IMHO).
Riki, do you want me to draft something, or are you going to take care?
I usually do that when preparing the release, but if you want to write
something now about this particular issue, that'll give me a head start.
It turned out that this is more complex than expected. I drafted a text
(partially stolen from the last 2.3.x release), and then I realized that
we have checks for the minimum python version. I updated these as well.
What I do not know is whether building with MSVC on windows does still
work. Is lyx-windows-deps-msvc2019_64.zip still relevant? This archive
does still contain python 2.7. Who is responsible for that?

-Public release of LyX version 2.4.4
+Public release of LyX version 2.4.5
===================================
-We are proud to announce the release LyX 2.4.4, the fourth maintenance
-release in the 2.4.x series. We have fixed a number of bugs, including some
-crashes, and introduced a few new features.
+We are proud to announce the release LyX 2.4.5. This is the fifth and
+final maintenance release in the 2.4.x series. LyX 2.5.0 will be released
+very shortly, so many users may wish to wait for that rather than upgrading
+to 2.4.5. Some users, however, may want or need to continue using the 2.4.x
+series. We encourage those users to upgrade to this version.
+
+LyX 2.4.5 is the result of on-going efforts to make our stable version
+more reliable and more stable. Several bugs and crashes have been fixed here,
+but the main addition is the ability to import and export files in the new
+2.5.x format.
+
+The import and export capability of files in the 2.5.x format requires a
+higher minimum python than previous releases in the 2.4.x series. The minimum
+python version is now python 3.6.0 instead of python 2.7.0 or 3.5.0.
