The RcppSimdJson package was just updated to release 0.1.8 today.
RcppSimdJson wraps the fantastic and genuinely impressive simdjson library by Daniel Lemire and collaborators. Via very clever algorithmic engineering to obtain largely branch-free code, coupled with modern C++ and newer compiler instructions, it results in parsing gigabytes of JSON parsed per second which is quite mindboggling. The best-case performance is ‘faster than CPU speed’ as use of parallel SIMD instructions and careful branch avoidance can lead to less than one cpu cycle per byte parsed; see the video of the talk by Daniel Lemire at QCon.
This release simply changes one statement to not trigger a warning under clang++-14
.
The very short NEWS entry for this release follows.
Changes in version 0.1.8 (2022-10-18)
- Use the '||' operator instead of '|' on a set of booleans to appease 'clang-14'.

Release 0.6.30 of the digest package arrived at CRAN earlier today, and was just uploaded to Debian as well.
digest creates hash digests of arbitrary R objects (using the md5
, sha-1
, sha-256
, sha-512
, crc32
, xxhash32
, xxhash64
, murmur32
, spookyhash
, and blake3
algorithms) permitting easy comparison of R language objects. It is a mature and widely-used as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation to quickly identify the various objects.
This release contains two tiny changes on old standard C code to appease the new / upcoming clang-15
release now used by CRAN in their forward-looking checks.
My CRANberries provides the usual summary of changes to the previous version. For questions or comments use the issue tracker off the GitHub repo.
