Aside from the usual collection of minor bugfixes and tweaks, the new version features a rewritten completion function which consolidates all the old bits and pieces, and a new customisable layout.
This is the first release of BBDB in two years. Its main new features are a new database format with better support for non-US addresses, provision for multiple records with the same name, autoconf build system, support for merging databases, many bugfixes, and an assortment of minor hacks.
