A new version of digest arrived at CRAN earlier today, and I just sent an updated package to Debian too.

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 pretty much exactly one month after the very nice 0.6.21 release but contains five new pull requests. Matthew de Queljoe did a little bit of refactoring of the vectorised digest function he added in 0.6.21. Ion Suruceanu added a CFB cipher for AES. Bill Denney both corrected and extended sha1. And Jim Hester made the windows-side treatment of filenames UTF-8 compliant.

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