[ Wookey ] * Support for cross-compiling has been added. This includes the addition of $host and $build configuration variables, with corresponding --host and --build command-line options. This includes the addition of a new 'xapt' dependency resolver. - Merge cross-build support (thanks to Hector Oron, Closes: #610689). - Add multiarch cross-build support.
[ Roger Leigh ] * The deprecated 'internal' dependency resolver has been removed, along with the configuration variables $apt_policy, $check_depends_algorithm and $resolve_virtual, and the command-line option --check-depends-algorithm. The 'apt' resolver is the default replacement for 'internal'. (Closes: #622788) * Support for watches has been removed. The configuration variables $check_watches, $ignore_watches_no_build_deps and $watches (and obsolete variables @ignore_watches_no_build_deps and %watches) have also been removed. * sbuild-stats and support for build time and space statistics recording has been removed. These statistics are recorded in both the build log and are available as build metadata internally. The statistics recorded in the database were not particularly informative; storing the statistics in a proper relational database is recommended. The configuration variables $avg_time_db and $avg_space_db have been removed. * Drop 25nssdatabases schroot setup script used on compatibility mode (on buildds). This has been replaced by the schroot 20nssdatabases for many years.
