Another new version of digest got onto CRAN earlier today, and was also uploaded to Debian.

digest creates hash digests of arbitrary R objects (using the md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, and spookyhash algorithms) permitting easy comparison of R language objects. It is a fairly widely-used package (currently listed at 868k monthly downloads) as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation.

This release comes again one month after the previous release and contains further refinements for sha1 digests, thanks once more to Bill Denney and Thierry Onkelinx who added more support for formulae and better support for object attributes. I added some refinement for the encoding / utf8 filename tests from the previous to round things off.

CRANberries provides the usual summary of changes to the previous version.
