# Deprecated Apple APIs and the macos-version-min value required to avoid
# deprecation warnings with llvm/clang:
#
# - 10.7  Lion (2011)          - GSS
# - 10.8  Mountain Lion (2012) - CFURLCreateDataAndPropertiesFromResource (used by curl Secure Transport code)
# - 10.9  Mavericks (2013)     - LDAP
# - 10.14 Mojave (2018)        - Secure Transport
#
# For Secure Transport, curl implements features that require a target
# newer than the 10.8 required by `CFURLCreateDataAndPropertiesFromResource`.
