@@ -6,3 +6,9 @@ similar to vkeybd, except it uses JACK MIDI instead of ALSA, and the
 default keyboard mapping is much better - it uses the same layout as
 trackers (like Impulse Tracker) did, so you have two and half octaves
 under your fingers.

+This package uses POSIX filesystem capabilities to execute with
+elevated privileges (required for realtime audio processing). This
+may be considered a security/stability risk. Please read
+http://www.slackbuilds.org/caps/ for more information. To disable
+capabilities, pass SETCAP=no to the script.

+# 20170216 bkw:
+# - Updated for v2.7.1. Apparently, upstream released 2.7.1 in 2012, but
+#   never got around to updating their web page, which still says that
+#   2.5 is the latest release. It took me this long (5 years!) to notice
+#   there was a newer version on their sourceforge download page. Note
+#   that 2.5 used autotools but 2.7.1 uses cmake, so this script can no
+#   longer be used to build the old version.
+# - Add capability stuff.
