Dirk Eddelbuettel: RcppSpdlog 0.0.26 on CRAN: Another Microfix

Version 0.0.26 of RcppSpdlog arrived
on CRAN moments ago, and will
be uploaded to Debian and built for
r2u shortly. The (nice)
documentation
site has been refreshed too. RcppSpdlog
bundles spdlog, a
wonderful header-only C++ logging library with all the bells and
whistles you would want that was written by Gabi Melman, and also includes fmt by Victor Zverovich. You can learn
more at the nice package
documention site.

Brian Ripley noticed an infelicity when building under C++20 which he
is testing hard and fast. Sadly, this came a day late for yesterday’s
upload of release 0.0.25 with another trivial fix so another incremental
release was called for. We already accommodated C++20 and its use of
std::format (in lieu of the included
fmt::format) but had not turned it on
unconditionally. We do so now, but offer an opt-out for those
who prefer the previous build type.

The NEWS entry for this release follows.

Changes in
RcppSpdlog version 0.0.26 (2026-01-16)

• Under C++20 or later, switch to using std::format to
  avoid a compiler nag that CRAN now complains about

Courtesy of my CRANberries, there
is also a diffstat
report detailing changes. More detailed information is on the RcppSpdlog
page, or the package documention
site.
