+
REQUIRED_USE supports new at-most-one-of operator
+
+ The new at-most-one-of operator consists of the string '??', and is satisfied if zero or one (but no more) of its child elements is matched. +
+
+
SLOT supports optional "sub-slot" part
+
+ The SLOT variable may contain an optional sub-slot part that follows the regular slot and is delimited by a / character. The sub-slot must be a valid slot name. The sub-slot is used to represent cases in which an upgrade to a new version of a package with a different sub-slot may require dependent packages to be rebuilt. When the sub-slot part is omitted from the SLOT definition, the package is considered to have an implicit sub-slot which is equal to the regular slot. +
+
+
Dependency atom slot operators
+
+ A slot dependency may contain an optional sub-slot part that follows the regular slot and is delimited by a / character. An operator slot dependency consists of a colon followed by one of the following operators: +
+
- + * Indicates that any slot value is acceptable. In addition, for runtime dependencies, indicates that the package will not break if the matched package is uninstalled and replaced by a different matching package in a different slot. +
- + = Indicates that any slot value is acceptable. In addition, for runtime dependencies, indicates that the package will break unless a matching package with slot and sub-slot equal to the slot and sub-slot of the best installed version at the time the package was installed is available. +
- + slot= Indicates that only a specific slot value is acceptable, and otherwise behaves identically to the plain equals slot operator. +
+

+
Profile stable USE forcing and masking
+
+ In profile directories with an EAPI supporting stable masking, new USE configuration files are supported: use.stable.mask, use.stable.force, package.use.stable.mask and package.use.stable.force. These files behave similarly to previously supported USE configuration files, except that they only influence packages that are merged due to a stable keyword. +
+

+
econf adds --disable-silent-rules
+
+ This option will automatically be passed if --disable-silent-rules occurs in the output of configure --help. +
+
+
new* commands can read from standard input
+
+ Standard input is read when the first parameter is - (a hyphen). +
+
+
New option --host-root for {has,best}_version
+
+ This option --host-root will cause the query to apply to the host root instead of ROOT. +
+
+
New doheader helper function
+
+ Installs the given header files into /usr/include/, by default with file mode 0644. This can be overridden by setting INSOPTIONS with the insopts function. +
+

New usex helper function

+ +

+USAGE: usex 〈USE flag〉 [true output] [false output] [true suffix] [false suffix]
+DESCRIPTION:
+If USE flag is set, echo [true output][true suffix] (defaults to "yes"),
+ otherwise echo [false output][false suffix] (defaults to "no").
+

+ + + + +Phases + +

+
src_test supports parallel tests
+
+ Unlike older EAPIs, the default src_test implementation will not pass the -j1 option to emake. +
+

+ + + + +Variables + +

+
EBUILD_PHASE_FUNC
+
+ During execution of an ebuild phase function (such as pkg_setup or src_unpack), + the EBUILD_PHASE_FUNC variable will contain the name of the phase function that is currently executing. +
