RcppSpdlog 0.0.24 on CRAN: New Upstream

Thu, 08 Jan 2026 08:59:00 CDT

Version 0.0.24 of RcppSpdlog arrived on CRAN today, has been been uploaded to Debian, and also been built for r2u. This follows an upstream release on Sunday which we incorporated immediately, but CRAN was still closed for the winter break until yesterday. 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.

This release updates the code to the version 1.17.0 of spdlog which was released yesterday morning, and includes version 12.1.0 of fmt. No other changes besides tweaks to the documentation site (that was updated to using altdoc last release) have been made.

The NEWS entry for this release follows.

Changes in RcppSpdlog version 0.0.24 (2026-01-07)

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.
