1 News (mainly features/major bug fixes)
6 * Allow per-module setting of PORTAGE_ELOG_CLASSES
7 * Add ** as new token for package.keywords to bypass the keyword visibility layer
8 * Namespace sanitizing: move all portage related code into portage.* namespace,
9 rename portage_foo modules to portage.foo (but keep symlinks for compability)
10 * Add license visibility filtering (GLEP 23)
11 * Add new elog module "echo" to simply display messages when emerge exits
12 * Enable "echo" and "save_summary" elog modules by default
13 * Fix -* handling in package.keywords to work as intended (reset the accepted
14 keywords list), also see RELEASE-NOTES.
15 * Experimental support for preserving old library files on package upgrades
16 based on FEATURES=preserve-libs, USE AT YOUR OWN RISK!!!
17 * Make elog functionality available to python code
18 * Add support for news items (GLEP 42)
23 * Ebuilds support default USE flags via +flag in IUSE.
24 * New-style virtuals are now usable for packages that depend on themselves for
26 * Profiles support multiple inheritance and package.use.
27 * CONFIG_PROTECT and CONFIG_PROTECT_MASK both support files (not just
29 * Collision protection handles symlinks properly.
30 * Dependencies can be satisfied by installed packages that do not have matching
31 ebuilds in the portage tree or overlay.
32 * Emerge automatically ignores blockers that are made irrelevant by an upgrade.
33 * Emerge supports "reverse blocker detection" which means that the blockers of
34 installed packages will always be respected.
35 * Emerge builds a complete dependency graph in order to ensure correct merge
36 order and detection of circular dependencies.
37 * The world and system sets allow automatic update of all installed slots.
38 * DEPEND atoms support SLOT dependencies of the form ${CATEGORY}/${PN}:${SLOT}.
39 * Development: Extend PYTHONPATH support to allow overriding the hardcoded
40 /usr/lib/portage/pym for development/testing purposes
41 * New "finalize" hook for elog modules enabling modules to perform actions on
42 shutdown (like dispatching collected messages).
43 * New elog modules mail_summary and save_summary that act like the mail/save
44 modules except that they merge messages from multiple packages in a single
46 * New QA loglevel and matching eqawarn function
47 * `ebuild foo test` now always runs src_test if available
48 * If DOC_SYMLINK_DIR is set portage installs symlinks to html documention there
49 * FEATURES="test" automatically implies USE="test".
54 * Profiles support use.force, package.use.force, and package.use.mask files.
56 portage-2.1 (ongoing via pre releases)
59 * FEATURES="confcache" integration; global caching to speed up configure calls,
60 requires dev-util/confcache
61 * elog framework and accompanying modules for logging ebuild warnings, errors
62 and general notices. Collects eerror/ewarn/elog/einfo messages.
63 * New elog function (should replace einfo in many cases)
64 * version syntax enhancements allowing multiple suffixes and a new 'cvs'
65 version prefix for denoting "live sources" ebuilds.
66 * config files as directories enabling more flexible settings management.
67 * Addition of an register_die_hook method that allows ebuild/eclasses to
68 register functions to be called for better debugging on errors.
69 * Addition of pre and post user hookable functions for each ebuild phase, accessible
70 via portage bashrc. Example would be pre_src_unpack .
71 * cache refactoring- runtime improvement from 35% -> 65%.
72 * Intelligently handle and display USE_EXPAND-based IUSE variables.
73 * FEATURES="parallel-fetch". Download in parallel to compilation.
74 * Include a "changed or new" USE flag output when --verbose isn't specified.
75 * Support for splitting out debug information into separate files in
77 * exec subsystem refactoring (now with less bugs!)
78 * Added sha256 and rmd160 hashes for digests/manifests
79 * Make --emptytree only apply to ${ROOT} rather than always including /.
80 * Allow packages to be upgraded that are only depended on via a
81 "|| ( =cat/pkg-1* =cat/pkg-2* )" construct.
82 * Ebuild output is no longer cut off early when using PORT_LOGDIR.
83 * Distfiles indirection- $DISTFILES access goes through a tmp dir to fail
84 access to files not listed in SRC_URI.
85 * Emerge now uses --resume to restart itself after portage upgrade.
86 * Atomic file updates via the new atomic_ofstream class.
87 * Global updates and fixpackages performance optimizations.
88 * Tests show that file locking is now more reliable.
89 * A bash call stack is printed when an ebuild dies in ebuild.sh.
90 * New rsync option handling by using a generic PORTAGE_RSYNC_EXTRA_OPTS variable
91 * Manifest2 support that will allow digest-* files to be eliminated from the tree.
