# 20180613 bkw: updated for 3.3.4.

# 20180111 bkw:
# - updated for 3.3.3.
# - remove unneeded command history patch.

# 20171225 bkw:
# - updated for 3.3.2.
# - add upstream patch (commit d857451) to fix a long-standing bug where
#   youtube-viewer's command history wasn't being saved across sessions.
#   NOTE TO SELF: remove this patch once 3.3.3 is released.

# 20171219 bkw: updated for 3.3.1.

# 20170921 bkw:
# - updated for 3.2.9.
# - add warning in README about outdated youtube-dl.

# 20170614 bkw: updated for 3.2.8.
# 20170423 bkw: updated for 3.2.7.
# 20170324 bkw: updated for 3.2.6.

# 20170301 bkw:
# - updated for 3.2.5.
# - use 'long format' download URL, as per David Spencer's post to
#   the mailing list (thanks David!)

# 20161017 bkw:
# - updated for 3.2.4.

# 20160804 bkw:
# - updated for 3.2.3.
# - ARCH=noarch, there is no compiled code here, only perl scripts.
# - mention perl-Term-ReadLine-Gnu optional dep in README. In case
#   you wonder about the other optional dep, Unicode::GCString,
#   it's an either-or with perl-Text-CharWidth. No need to install both,
#   and SBo doesn't have a perl-Unicode-GCString build anyway.

# 20150309 bkw: Updated for 3.1.4 release.
# Quite a bit of changes under the hood for what's supposed to be
# a point release: upstream dropped the XML::Fast dep and added
# JSON::XS.

# 20150309 bkw: Updated for 3.1.2 release

# 20140806 bkw:
# - Updated for 3.1.1 release. This adds a couple of new deps :(
# - Made perl-LWP-Protocol-https required instead of optional.

# 20140318 bkw:
# - Updated for 3.0.9 release
# - Added support for gtk-youtube-viewer
