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