# PLATFORM_SEPOLICY_VERSION is a number of the form "NN.m" with "NN" mapping to
# PLATFORM_SDK_VERSION and "m" as a minor number which allows for SELinux
# changes independent of PLATFORM_SDK_VERSION. This value will be set to
# 10000.0 to represent tip-of-tree development that is inherently unstable and
# thus designed not to work with any shipping vendor policy. This is similar in
# spirit to how DEFAULT_APP_TARGET_SDK is set.
# The minor version ('m' component) must be updated every time a platform release
# is made which breaks compatibility with the previous platform sepolicy version,
# not just on every increase in PLATFORM_SDK_VERSION. The minor version should
# be reset to 0 on every bump of the PLATFORM_SDK_VERSION.
