# Please check ABI on each bump, even if SONAMEs didn't change: bug #833355
# Use e.g. app-portage/iwdevtools integration with dev-libs/libabigail's abidiff.
# Subslot: SONAME of each: <libgpgme.libgpgmepp.libqgpgme.FUDGE>
# Bump FUDGE if a release is made which breaks ABI without changing SONAME.
# (Reset to 0 if FUDGE != 0 if libgpgme/libgpgmepp/libqpggme change.)
