# 20230510 bkw: update for v4.0.3. remove the warning about D-Bus from README,
#               it no longer applies (transmission-gtk works without it).
# 20230320 bkw: update for v4.0.2. add -DREBUILD_WEB=OFF to allow building
#               without using the network, if nodejs is installed. thanks
#               to Ruben Schuller for pointing this out.
# 20230208 bkw: update for v4.0.0, which has only been out for about 5 hours.
# - Disable the qt5 UI by default. There's no reason to build both GUIs
#   by default. User can still say GTK=no QT=yes to get only the qt UI.
# 20210926 bkw: BUILD=2, restore Qt5 build. 15.0 not yet released, but "soon".
# 20200525 bkw: update for v3.00.
#               Drop Qt GUI and QT=yes, due to 14.2's old gcc/libstdc++.
#               It will come back when 15.0 releases.
# 20180611 bkw: update for v2.94.
# 20180207 bkw: update for v2.93.
# 20180116 bkw: security fix, BUILD=2. See:
#               https://github.com/transmission/transmission/pull/468
#               Thanks to Freenode user lord_ for pointing this out.
# 20170621 bkw: fix build on -current.
# 20150204 bkw: allow user to disable the various components.
# By default, all are enabled. We can disable transmission-gtk,
# transmission-qt, transmission-cli, and/or transmission-daemon.
# But disabling them all is no good.
