There is nothing in the diff besides the format number changing from
93 to 95. From what I understand, this is as expected since 93 -> 94
and 94 -> 95 just add new layout tags.
Updating the layouts makes it easier to test master. Otherwise, in
some use cases layout2layout can be run hundreds of times which can
make some things slow (e.g., opening documents or even opening the
advanced find pane).
The category tag was rarely used and thus not very useful. This adds
categorization to most modules (the rest will follow) and uses the
\DeclareCategory tag we use in layouts rather than the extra syntax
we used in modules. Categories are now added to the po files and
translated.
Note that this is work in progress: the current categories are still
subject to change.
The ultimate goal of this is to sort the modules in the GUI by category
as we do with layouts, examples and templates (and add a filter to search
for specific modules)
As it is now (with the many modules we accumulated), the module selector
is not really usable anymore. If you don't happen to know how exactly a
module is named, selecting a module is really a PITA.
