1 Release Notes; upgrade information mainly.
2 Features/major bugfixes are listed in NEWS
5 ==================================
7 * Depending on the number of packages installed, users may notice a difference
8 in the time taken for dependency calculations. This performance penalty is
9 due to the addition of important new features which include the ability to
10 detect reverse blockers, the building of a complete dependency graph, and the
11 ability to use installed packages to satisify dependencies even after their
12 ebuilds have been removed from the portage tree.
13 * emerge does not necessarily update build time dependencies that are not
14 strictly required. See the --with-bdeps option in the emerge(1) man page.
17 ==================================
19 * emerge --search doesn't use regular expressions now anymore by default, so
20 emerge --search dvd+rw-tools now works as expected. Regular expressions can be enabled
21 by prefixing the search string with %.
22 * emerge --depclean algorithm is much safer than the old one.
23 * emerge --newuse detects changes in IUSE that previously went undetected.
26 ==================================
28 * new cache framework, breaking all old cache modules.
29 If you're having problems with portage_db_cdb, this is likely the cause.
30 * USE flag output ordering has changed. The old ordering is now an option
31 by the name of --alphabetical. Adding the option to EMERGE_DEFAULT_OPTS
32 in make.conf will restore the old behaviour permanently.
33 * The deprecated --inject has been removed, use /etc/portage/profile/package.provided
34 * The deprecated --upgradeonly has been removed, use /etc/portage/package.*
36 * 'emerge sync' has been deprecated, use 'emerge --sync' instead (same
38 * Tools that call emerge should override the EMERGE_DEFAULT_OPTS environment
39 variable or use the emerge --ignore-default-opts option.
40 * rsync option handling has been redesigned, instead of RSYNC_* variables
41 use PORTAGE_RSYNC_EXTRA_OPTS from now on.
42 * autouse (use.defaults) has been deprecated by specifying USE_ORDER in make.defaults
43 Users may still turn this back on by specifying USE_ORDER="env:pkg:conf:auto:defaults"
44 in make.conf. Interested in figuring out what use flags were turned off? Check out
45 /usr/portage/profiles/base/use.defaults and other use.defaults files that correspond
