digest 0.6.13

A small maintenance release, version 0.6.13, of the digest package arrived on CRAN and in Debian yesterday.

digest creates hash digests of arbitrary R objects (using the ‘md5’, ‘sha-1’, ‘sha-256’, ‘crc32’, ‘xxhash’ and ‘murmurhash’ algorithms) permitting easy comparison of R language objects.

This release accomodates a request by Luke and Tomas to make the version argument of serialize() an argument to digest() too, which was easy enough to accomodate. The value 2L is the current default (and for now only permitted value). The ALTREP changes in R 3.5 will bring us a new, and more powerful, format with value 3L. Changes can be set in each call, or globally via options(). Other than we just clarified one aspect of raw vector usage in the manual page.

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