Constant Summary collapse

SYMBOLS =

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

Note:

When removing symbols here, ensure that they are added to DEPRECATED_MACOS_VERSIONS in MacOSRequirement.

Note:

Changes to this list must match macos_version_name in cmd/update.sh.

NULL =

This constant is part of a private API. This constant may only be used in the Homebrew/brew repository. Third parties should avoid using this constant if possible, as it may be removed or changed without warning.

Note:

Constructor needs to called with an arbitrary macOS-like version which is then set to nil.

Represents the absence of a version.
