# Upstream has haphazard versioning: after going through “v1”-“v6”, they
|

# selected a version “final1”, and are now working on “final2”. They also keep
|
||||
# all old versions in the git repository. We will package only based on the
|
||||
# “final” version numbers. When “final2” is released, this package will move
|
||||
# forward to that version, with “final1” offered in a parallel-installable
|
||||
# compat package.

#
|

# Since versioning is so wonky, we treat the git tag as a snapshot version.

No hash function is perfect, but some are useful.

wyhash and wyrand are the ideal 64-bit hash function and PRNG respectively:
|
||||
|
||||
solid: wyhash passed SMHasher, wyrand passed BigCrush, practrand.
|
||||
|
||||
portable: 64-bit/32-bit system, big/little endian.
|
||||
|
||||
fastest: Efficient on 64-bit machines, especially for short keys.
|

|
||||
simplest: In the sense of code size.}
