qlcal 0.0.17 on CRAN: Regular Update

Tue, 14 Oct 2025 12:55:00 CDT

The seventeenth release of the qlcal package arrivied at CRAN today, once again following a QuantLib release as 1.40 came out this morning.

qlcal delivers the calendaring parts of QuantLib. It is provided (for the R package) as a set of included files, so the package is self-contained and does not depend on an external QuantLib library (which can be demanding to build). qlcal covers over sixty country / market calendars and can compute holiday lists, its complement (i.e. business day lists) and much more. Examples are in the README at the repository, the package page, and course at the CRAN package page.

This releases mainly synchronizes qlcal with the QuantLib release 1.40. Only one country calendar got updated; the diffstat looks larger as the URL part of the copyright got updated throughout. We also updated the URL for the GPL-2 badge: when CRAN checks this, they always hit a timeout as the FSF server possibly keeps track of incoming requests; we now link to version from the R Licenses page to avoid this.
