Dirk Eddelbuettel: nanotime 0.3.13 on CRAN: Maintenance

Another minor update 0.3.13 for our nanotime
package is now on CRAN, and has
been uploaded to Debian and
compiled for r2u. nanotime
relies on the RcppCCTZ
package (as well as the RcppDate
package for additional C++ operations) and offers efficient high(er)
resolution time parsing and formatting up to nanosecond resolution,
using the bit64
package for the actual integer64 arithmetic. Initially
implemented using the S3 system, it has benefitted greatly from a
rigorous refactoring by Leonardo who not only rejigged
nanotime internals in S4 but also added new S4 types for
periods, intervals and durations.

This release, the first in eleven months, rounds out a few internal
corners and helps Rcpp with the
transition away from Rf_error to only using
Rcpp::stop which deals more gracefully with error
conditions and unwinding. We also updated how the vignette is made, its
references, updated the continuous integration as one does, altered how
the documentation site is built, gladly took a PR from Michael polishing another
small aspect, and tweaked how the compilation standard is set.

The NEWS snippet below has the fuller details.

Changes in version 0.3.13
(2026-03-08)

• The methods package is now a Depends as WRE
  recommends (Michael Chirico in #141 based
  on a suggestion by Dirk in #140)

• The mkdocs-material documentation site is now generated via altdoc

• Continuous Integration scripts have been updated

• Replace Rf_error with Rcpp::stop, turn
  remaining one into (Rf_error) (Dirk in #143)

• Vignette now uses the Rcpp::asis builder for
  pre-made pdfs (Dirk in #146 fixing
  #144)

• The C++ compilation standard is explicitly set to C++17 if an R
  version older than 4.3.0 is used (Dirk in #148 fixing
  #147)

• The vignette references have been updated

Thanks to my CRANberries, there
is a diffstat report for this
release. More details and examples are at the nanotime
page; code, issue tickets etc at the GitHub repository –
and all documentation is provided at the nanotime documentation
site.
