The hook that defines the "lastslide" label is interfered with for
some reason on an updated TeX Live 2020. We thus avoid referencing
the label and instead show only the current slide number on each
slide. We leave instructions in the preamble for how to get back the
previous behavior if desired.
We currently specify that dvips be used. This could potentially
change in the future. One issue is that with system fonts XeTeX and
LuaTeX do not correctly rotate pages.
Compilation of our Seminar example file fails on updated TL20. The
maintainer of "Seminar" is not planning to fix the core issue and
states the following (in a private email with permission to quote):
it is a problem with the new hook management of the current latex.ltx
seminar is a quite old package and there is no reason to use it with a
new LaTeX format. It won't be fixed, so the usual way is to use the
package latexrealease to get the old hook management.
This commit adds a note to the example files explaining the
workaround of exporting to a .tex file and prepending the following
line:
\RequirePackage[2020-02-02]{latexrelease}
We now invert the relevant tests.
Re-structure and rename files in a transparent way. Most template/example
names now correspond to the (verbose GUI) name of their layouts.
Note that this, most prominently, also changes [LANG/]splash.lyx to
something less insiderish, namely "Welcome.lyx".
