# Please don't copy-paste the same pre-release tag for new entries above!!!
# You should always use the *upcoming* tag. For example, if 3.12a6 came out
# a week ago, I should put "Python 3.12a7" next to my new magic number.

# MAGIC must change whenever the bytecode emitted by the compiler may no
# longer be understood by older implementations of the eval loop (usually
# due to the addition of new opcodes).
