# 20201115 bkw: Add missing fix_zipdir.diff. Dammit.
# 20201107 bkw: Updated for 4.5.0.
# 20201027 bkw:
# - Updated for 4.4.2.
# - Add new zmusic dep.
# - Use 'make install/strip' now that it's supported.
# - Use upstream's icon, multiple sizes in /usr/share/icons.
# 20200302 bkw: Updated for 4.3.3.
# 20191201 bkw: Updated for 4.2.4.
# 20181022 bkw: Updated for 3.6.0.
# 20180827 bkw: Updated for 3.5.1.
# 20180801 bkw: Updated for 3.5.0.
# 20180623 bkw: Updated for 3.4.1 (released the day after my 3.4.0 update).
# 20180612 bkw: Updated for 3.4.0.
# 20180104 bkw: Updated for 3.2.5.
# 20171222 bkw: Updated for 3.2.4.
# 20170608 bkw:
# - Updated for 3.1.0. fmodapi support has been removed by upstream, so
#   it's no longer a dep.
# - Add OpenAL as a dep. Technically it's not required, as gzdoom will
#   happily compile & run without it... but it won't be able to make
#   any sound at all. Nobody wants this. If you disagree with my decision
#   to make OpenAL a hard dep, I don't want to hear about it (you won't
#   be able to make sound anyway, so I won't have to...)
# - Stop supporting old versions of gzdoom. The old versions are now
#   supported as "gzdoom-legacy" for those that need them.
