digest 0.6.18

Share Tweet

Earlier today, digest version 0.6.18 arrived on CRAN. It will get uploaded to Debian in due course.

digest creates hash digests of arbitrary R objects (using the md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64 and murmur32 algorithms) permitting easy comparison of R language objects.

As I wrote when announcing the 0.6.17 release about a month ago

[…] it also squashed one UBSAN error under the standard gcc setup. But two files remain with UBSAN issues, help would be welcome!

And lo and behold, and withing a day or two, Jim Hester saw this, looked at it and updated xxHash (which had contributed to digest 0.6.5 in 2014) to the newest version, taking care of one part. And Radford Neal took one good hard look at the remaining issue and suggested a cast for pmurhash. In testing against the UBSAN instance at RHub, both issues appear to be taken care of. So a big Thank You to both Jim and Radford!

No other changes were made.

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