1 News (mainly features/major bug fixes)
6 * Ebuilds support default USE flags via +flag in IUSE.
7 * New-style virtuals are now usable for packages that depend on themselves for
9 * Profiles support multiple inheritance and package.use.
10 * CONFIG_PROTECT and CONFIG_PROTECT_MASK both support files (not just
12 * Collision protection handles symlinks properly.
13 * Dependencies can be satisfied by installed packages that do not have matching
14 ebuilds in the portage tree or overlay.
15 * Emerge automatically ignores blockers that are made irrelevant by an upgrade.
16 * Emerge builds a complete dependency graph in order to ensure correct merge
17 order and detection of circular dependencies.
18 * The world and system sets allow automatic update of all installed slots.
19 * DEPEND atoms support SLOT dependencies of the form ${CATEGORY}/${PN}:${SLOT}.
20 * Development: Extend PYTHONPATH support to allow overriding the hardcoded
21 /usr/lib/portage/pym for development/testing purposes
22 * New "finalize" hook for elog modules enabling modules to perform actions on
23 shutdown (like dispatching collected messages).
24 * New elog modules mail_summary and save_summary that act like the mail/save
25 modules except that they merge messages from multiple packages in a single
31 * Profiles support use.force, package.use.force, and package.use.mask files.
33 portage-2.1 (ongoing via pre releases)
36 * FEATURES="confcache" integration; global caching to speed up configure calls,
37 requires dev-util/confcache
38 * elog framework and accompanying modules for logging ebuild warnings, errors
39 and general notices. Collects eerror/ewarn/elog/einfo messages.
40 * New elog function (should replace einfo in many cases)
41 * version syntax enhancements allowing multiple suffixes and a new 'cvs'
42 prefix for denoting "live sources" ebuilds.
43 * config files as directories enabling more flexible settings management.
44 * Addition of an register_die_hook method that allows ebuild/eclasses to
45 register functions to be called for better debugging on errors.
46 * Addition of pre and post user hookable functions for each ebuild phase, accessible
47 via portage bashrc. Example would be pre_src_unpack .
48 * cache refactoring- runtime improvement from 35% -> 65%.
49 * Intelligently handle and display USE_EXPAND-based IUSE variables.
50 * FEATURES="parallel-fetch". Download in parallel to compilation.
51 * Include a "changed or new" USE flag output when --verbose isn't specified.
52 * Support for splitting out debug information into separate files in
54 * exec subsystem refactoring (now with less bugs!)
55 * Added sha256 and rmd160 hashes for digests/manifests
56 * Make --emptytree only apply to ${ROOT} rather than always including /.
57 * Allow packages to be upgraded that are only depended on via a
58 "|| ( =cat/pkg-1* =cat/pkg-2* )" construct.
59 * Ebuild output is no longer cut off early when using PORT_LOGDIR.
60 * Distfiles indirection- $DISTFILES access goes through a tmp dir to fail
61 access to files not listed in SRC_URI.
62 * Emerge now uses --resume to restart itself after portage upgrade.
63 * Atomic file updates via the new atomic_ofstream class.
64 * Global updates and fixpackages performance optimizations.
65 * Tests show that file locking is now more reliable.
66 * A bash call stack is printed when an ebuild dies in ebuild.sh.
67 * New rsync option handling by using a generic PORTAGE_RSYNC_EXTRA_OPTS variable
68 * Manifest2 support that will allow digest-* files to be eliminated from the tree.
