Release Notes; upgrade information mainly. Features/major bugfixes are listed in NEWS portage-2.1.2 ================================== * Depending on the number of packages installed, users may notice a difference in the time taken for dependency calculations. This performance penalty is due to the addition of important new features which include the ability to detect reverse blockers, the building of a complete dependency graph, and the ability to use installed packages to satisify dependencies even after their ebuilds have been removed from the portage tree. * emerge does not necessarily update build time dependencies that are not strictly required. See the --with-bdeps option in the emerge(1) man page. portage-2.1.1 ================================== * emerge --search doesn't use regular expressions now anymore by default, so emerge --search dvd+rw-tools now works as expected. Regular expressions can be enabled by prefixing the search string with %. * emerge --depclean algorithm is much safer than the old one. * emerge --newuse detects changes in IUSE that previously went undetected. portage-2.1 ================================== * new cache framework, breaking all old cache modules. If you're having problems with portage_db_cdb, this is likely the cause. * USE flag output ordering has changed. The old ordering is now an option by the name of --alphabetical. Adding the option to EMERGE_DEFAULT_OPTS in make.conf will restore the old behaviour permanently. * The deprecated --inject has been removed, use /etc/portage/profile/package.provided * The deprecated --upgradeonly has been removed, use /etc/portage/package.* instead. * 'emerge sync' has been deprecated, use 'emerge --sync' instead (same for other actions) * Tools that call emerge should override the EMERGE_DEFAULT_OPTS environment variable or use the emerge --ignore-default-opts option. * rsync option handling has been redesigned, instead of RSYNC_* variables use PORTAGE_RSYNC_EXTRA_OPTS from now on. * autouse (use.defaults) has been deprecated by specifying USE_ORDER in make.defaults Users may still turn this back on by specifying USE_ORDER="env:pkg:conf:auto:defaults" in make.conf.
