A brand new release 0.1.15 of the RcppSimdJson package is now on CRAN.
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 version updates to the current 4.2.4 upstream release. It also
updates the RcppExports.cpp file with ‘glue’ between C++
and R. We want move away from using Rf_error() (as
Rcpp::stop() is generally preferable). Packages (such as
this one) that are declaring an interface have an actual
Rf_error() call generated in RcppExports.cpp
which can protect which is what current Rcpp code
generation does. Long story short, a minor internal reason.
The short NEWS entry for this release follows.

An update to the gunsales package is
now on CRAN. As in the last
update nine years ago (!!), changes are mostly internal. An upcoming
dplyr change requires a switch from the old and soon
to-be-removed ‘underscored’ verb form; that was kindly addressed in an
incoming pull request. We also updated the CI scripts a few times during
this period as needed, and switched to using Authors@R, and refreshed
and updated a number of URL references.
