* usr/lib/byobu/updates_available: - localize variables - save a fork - fix detection of updates, which only worked when there were security updates * usr/lib/byobu/.shutil: LP: #844994 - the wget --timeout=1 was not working as desired, without the --tries=1 option too; so local boots of ubuntu ec2 images that don't have a working metadata service might take several minutes for byobu to start while that wget tries repeatedly to reach the metadata service; big thanks to Ben Howard for helping triage and fix ;-) * usr/lib/byobu/apport: LP: #842113 - fix broken detection of apport bug reports, thanks to lp:~masterpatricko for the suggested fix * etc/byobu/backend, usr/bin/byobu, usr/lib/byobu/.common, usr/lib/byobu/.dirs, usr/share/byobu/status/status, usr/share/man/man1/byobu.1: LP: #836090 - fix handling of byobu backend (screen|tmux) handling; thanks to lp:~zorun-42 for the fix * usr/lib/byobu/swap: LP: #843446 - make swap status behave like disk and memory (display usage even if zero)
