The development cycle of the next major branch, APT 1.3, is happening on the experimental channel, which in time will be slowly pushed to unstable/testing, and even the stable channel. The first milestone, apt 1.3~exp1 was released a couple of days ago bringing some major new features. Among these, we can mention support for multiple fingerprints in Signed-By, the ability to use the same redirection mirror for all index files, proper formatting of multiline error messages, and the use of the EXPKEYSIG variable instead of KEYEXPIRED for gpgv (GNU Privacy Guard).
