1 Release Notes; upgrade information mainly.
2 Features/major bugfixes are listed in NEWS
5 ==================================
7 * Portage now requires >=python-2.4, but doesn't need pycrypto anymore if
8 >=python-2.5 is installed and openssl supports the rmd160 hash.
9 * The python namespace for portage has been sanitized, all portage related code
10 is now contained within the portage namespace. External script should be updated
11 accordingly, though links exist for backward compability.
12 * -* support in package.keywords was changed as it was inconsistent with
13 ACCEPT_KEYWORDS behavior (also see http://dev.gentoo.org/~genone/docs/KEYWORDS.stupid).
14 Previously having -* in package.keywords matched packages with KEYWORDS="-*",
15 now it resets the ACCEPT_KEYWORDS list for the given atom like it does when
16 used in ACCEPT_KEYWORDS.
17 For packages that don't specify any other KEYWORDS you can use the new ** token
18 as documented in portage(5) to disable KEYWORDS filtering completely.
19 * Portage now warns if a ebild repository does not have a name, as several new
20 features in 2.2 make use of or require named repositories. The repository name
21 is stored in profiles/repo_name in each repository.
24 ==================================
26 * The "save_summary" and "echo" elog modules are now enabled by default. Setting
27 PORTAGE_ELOG_SYSTEM in make.conf will override this, so if you don't want elog
28 set PORTAGE_ELOG_SYSTEM="" in make.conf
29 * The unmerge process will remove any file that is not claimed by another
30 package in the same slot and is not protected by CONFIG_PROTECT, even if the
31 modification time or checksum differs from the file that was originally
32 installed. The old behavior is still available by adding -unmerge-orphans
34 * The world file now supports slot atoms such as 'sys-devel/gcc:3.4'. In some
35 cases, emerge --depclean may remove slots that it would not have removed
36 in the past. The emerge --noreplace command can be used to add an atom to the
37 world file and prevent matching packages from being removed. A slot atom
38 will be recorded in the world file for any atom that is precise enough to
39 identify a specific slot.
42 ==================================
44 * Depending on the number of packages installed, users may notice a difference
45 in the time taken for dependency calculations. This performance penalty is
46 due to the addition of important new features which include the ability to
47 detect reverse blockers, the building of a complete dependency graph, and the
48 ability to use installed packages to satisify dependencies even after their
49 ebuilds have been removed from the portage tree.
50 * emerge does not necessarily update build time dependencies that are not
51 strictly required. See the --with-bdeps option in the emerge(1) man page.
54 ==================================
56 * emerge --search doesn't use regular expressions now anymore by default, so
57 emerge --search dvd+rw-tools now works as expected. Regular expressions can be enabled
58 by prefixing the search string with %.
59 * emerge --depclean algorithm is much safer than the old one.
60 * emerge --newuse detects changes in IUSE that previously went undetected.
63 ==================================
65 * new cache framework, breaking all old cache modules.
66 If you're having problems with portage_db_cdb, this is likely the cause.
67 * USE flag output ordering has changed. The old ordering is now an option
68 by the name of --alphabetical. Adding the option to EMERGE_DEFAULT_OPTS
69 in make.conf will restore the old behaviour permanently.
70 * The deprecated --inject has been removed, use /etc/portage/profile/package.provided
71 * The deprecated --upgradeonly has been removed, use /etc/portage/package.*
73 * 'emerge sync' has been deprecated, use 'emerge --sync' instead (same
75 * Tools that call emerge should override the EMERGE_DEFAULT_OPTS environment
76 variable or use the emerge --ignore-default-opts option.
77 * rsync option handling has been redesigned, instead of RSYNC_* variables
78 use PORTAGE_RSYNC_EXTRA_OPTS from now on.
79 * autouse (use.defaults) has been deprecated by specifying USE_ORDER in make.defaults
80 Users may still turn this back on by specifying USE_ORDER="env:pkg:conf:auto:defaults"
81 in make.conf. Interested in figuring out what use flags were turned off? Check out
82 /usr/portage/profiles/base/use.defaults and other use.defaults files that correspond
