A Raspbian repository has been added for Raspberry Pi (thanks to Nils G. for building the packages every night).
The existing Debian repositories are being moved from flashtux.org to weechat.org, like the new Raspbian one. Repositories on weechat.org are already available, therefore it is recommended to use them now.
IMPORTANT: the WeeChat packages on debian.flashtux.org are still built every night, but they will be definitely removed on 2013-03-01.
A new section has been added on download page with a summary of all repositories: https://weechat.org/download/debian/.
