Regarding bug 328963 I think we should add a einfo/ewarn to the ebuild in the pkg_postinst section to inform tmux users they should check their conf because a few commands have been removed and cause tmux to output warnings/errors. My english isn't really good so I won't write the real message but maybe something like this: ewarn "Commands up-pane (upp), down-pane (downp) and select-prompt have been replaced by a new syntax." ewarn "You might want to check your configuration file and update it according to the 1.3 changes. ewarn "See http://tmux.cvs.sourceforge.net/viewvc/tmux/tmux/CHANGES for detailed informations." Also note that tmux.vim hasn't been updated accordingly to the modifications, I've sent a patch upstream so I don't know if we should wait it's getting applied or apply if ourselves, doesn't look really critical, though.
It might also be nice to warn users that a newer client won't work against an older server or vice versa.
I agree. In a pkg_preinst section then so that they can press ctrl-c.
fixed, I added a pretty thorough warning in pkg_setup :) thanks for reporting!
Thanks for the ewarn commit. But, it has a typo. Not sure I should have reopened the bug for this, so I just say it: "You'll have to use an existing client to to end your old session" ; there is two "to" in there ;)
nice catch. fixed :)
