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