"""Record of phased-in incompatible language changes.\r
\r
Each line is of the form:\r
\r
    FeatureName = "_Feature(" OptionalRelease "," MandatoryRelease ","\r
                              CompilerFlag ")"\r
\r
where, normally, OptionalRelease < MandatoryRelease, and both are 5-tuples\r
of the same form as sys.version_info:\r
\r
    (PY_MAJOR_VERSION, # the 2 in 2.1.0a3; an int\r
     PY_MINOR_VERSION, # the 1; an int\r
     PY_MICRO_VERSION, # the 0; an int\r
     PY_RELEASE_LEVEL, # "alpha", "beta", "candidate" or "final"; string\r
     PY_RELEASE_SERIAL # the 3; an int\r
    )\r
\r
OptionalRelease records the first release in which\r
\r
    from __future__ import FeatureName\r
\r
was accepted.\r
\r
In the case of MandatoryReleases that have not yet occurred,\r
MandatoryRelease predicts the release in which the feature will become part\r
of the language.\r
\r
Else MandatoryRelease records when the feature became part of the language;\r
in releases at or after that, modules no longer need\r
\r
    from __future__ import FeatureName\r
\r
to use the feature in question, but may continue to use such imports.\r
\r
MandatoryRelease may also be None, meaning that a planned feature got\r
dropped.\r
\r
Instances of class _Feature have two corresponding methods,\r
.getOptionalRelease() and .getMandatoryRelease().\r
\r
CompilerFlag is the (bitfield) flag that should be passed in the fourth\r
argument to the builtin function compile() to enable the feature in\r
dynamically compiled code.  This flag is stored in the .compiler_flag\r
attribute on _Future instances.  These values must match the appropriate\r
#defines of CO_xxx flags in Include/compile.h.\r
\r
No feature line is ever to be deleted from this file.\r
