[BRLTTY] 4.5 release

[Jean-Philippe MENGUAL]

Hi,

Does the translation need to be up-to-dated? So far, while I could install
on my computer the dev release on Monday, today autogen says:
forbuild.mk: no such file or directory

So I can't generate .po files (or search for the proper command to pass in order to
generate .po files to update as I've forgot it and lost my notes about doing
this).

What about the manual? Need to be updated?

I'm sorry for tardi(e reaction but I only have a working system for some days
after some tests.

Sincerely,
