RProtoBuf 0.4.26 on CRAN: More Maintenance

Sat, 07 Mar 2026 07:25:00 CDT

A new maintenance release 0.4.26 of RProtoBuf arrived on CRAN today. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol. The new release is also already as a binary via r2u.

This release brings an update to aid in an ongoing Rcpp transitions from Rf_error to Rcpp::stop, and includes a few more minor cleanups including one contributed by Michael.

The following section from the NEWS.Rd file has full details.

Changes in RProtoBuf version 0.4.26 (2026-03-06)

Minor cleanup in DESCRIPTION depends and imports

Remove obsolete check for utils::.DollarNames (Michael Chirico in #111)

Replace Rf_error with Rcpp::stop, turn remaining one into (Rf_error) (Dirk in #112)

Update configure test to check for RProtoBuf 3.3.0 or later

Thanks to my CRANberries, there is a diff to the previous release. The RProtoBuf page has copies of the (older) package vignette, the ‘quick’ overview vignette, and the pre-print of our JSS paper. Questions, comments etc should go to the GitHub issue tracker off the GitHub repo.
