Release Notes; upgrade information mainly. Features/major bugfixes are listed in NEWS portage-2.2 ================================== * The python namespace for portage has been sanitized, all portage related code is now contained within the portage namespace. External script should be updated accordingly, though links exist for backward compability. * -* support in package.keywords was changed as it was inconsistent with ACCEPT_KEYWORDS behavior (also see http://dev.gentoo.org/~genone/docs/KEYWORDS.stupid). Previously having -* in package.keywords matched packages with KEYWORDS="-*", now it resets the ACCEPT_KEYWORDS list for the given atom like it does when used in ACCEPT_KEYWORDS. For packages that don't specify any other KEYWORDS you can use the new ** token as documented in portage(5) to disable KEYWORDS filtering completely. * Portage now warns if an ebuild repository does not have a name, as several new features in 2.2 make use of or require named repositories. The repository name is stored in profiles/repo_name in each repository. portage-2.1.3 ================================== * Portage now requires >=python-2.4, but doesn't need pycrypto anymore if >=python-2.5 is installed and openssl supports the rmd160 hash. * The "save_summary" and "echo" elog modules are now enabled by default. Setting PORTAGE_ELOG_SYSTEM in make.conf will override this, so if you don't want elog set PORTAGE_ELOG_SYSTEM="" in make.conf * The unmerge process will remove any file that is not claimed by another package in the same slot and is not protected by CONFIG_PROTECT, even if the modification time or checksum differs from the file that was originally installed. The old behavior is still available by adding -unmerge-orphans to FEATURES. * The world file now supports slot atoms such as 'sys-devel/gcc:3.4'. In some cases, emerge --depclean may remove slots that it would not have removed in the past. The emerge --noreplace command can be used to add an atom to the world file and prevent matching packages from being removed. A slot atom will be recorded in the world file for any atom that is precise enough to identify a specific slot. * For safer operation, emerge --prune will not unmerge packages that have reverse dependencies. Use --verbose to display reverse dependencies. Use --nodeps to completely ignore dependencies. * emerge --depclean now accepts atoms and will unmerge only the specified packages if nothing depends on them. Use --verbose to display reverse dependencies. 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.
