The imap.tar.Z on this directory points to the currently recommended version of the UW IMAP toolkit, including the UW IMAP server. Usually, this will either be a final or release candidate version; but it may point to a development snapshot if it is felt that there is a critical known bug in the most recent final version. IMAP distribution names consist of "imap-", followed by the major version (which corresponds to the year of release), a possible letter which indicates a minor revision, and a distribution status, which is one of the following: FINAL (or no status) This is the final, permanently frozen distribution of that verion. Typically this is associated with a release of Pine. RCn This is a distribution that is a candidate to become a FINAL. Typically this is associated with a pre-release of Pine. DEV.SNAP-yymmddhhmm This is a snapshot of the current development sources, with the date/time that the the snapshot was taken. Development snapshots are believed to be good versions, but they can (and will) be updated frequently. Old permanently-frozen versions of the IMAP toolkit are on the old/ subdirectory. Note that all permanently-frozen versions have known bugs.
