Another new version of digest arrived on CRAN (and also on Debian) earlier today.
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 889k monthly downloads with 255 direct reverse dependencies and 7340 indirect reverse dependencies) as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation.
This release comes a few month after the previous release. It contains a few contributed fixes, some of which prepare for R 4.0.0 in its current development. This includes a testing change to the matrix/array class, and corrects the registration for the PMurHash routine as pointed out by Tomas Kalibera and Kurt Hornik (who also kindly reminded me to finally upload this as I had made the fix already in December). Moreover, Will Landau sped up one operation affecting his popular drake pipeline toolkit. Lastly, Thierry Onkelinx corrected one more aspect related to sha1.
CRANberries provides the usual summary of changes to the previous version.
