# 20250121 bkw: updated for v2.16, which has actual new features.
# - build with XInput (multitouch) support.
# - build with capabilities (libcap) support.
# - fix formatting in man page.
# - silence compiler warnings.

# 20210219 bkw: updated for v2.15.
# 20201208 bkw: updated for v2.14, although the only changes
# since 2.13 are in the debian packaging (which we don't/can't
# use). Basically just updating it to avoid people asking for it to
# be updated.
