A new minor release 0.4.28 of RProtoBuf arrived on CRAN today. RProtoBuf provides R with bindings to 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 corrects a really old bug. Troy found, when working on gRPC based extensions, which is in and by itself exciting, that a small part of our interface surface (for service descriptors) was just wrong confusing single and double underscores. adjusts to a change upstream. This has been corrected. I updated a few of the usual continuous integration parts, updated a help page for a newly-added nag by CRAN, and also got a last-minute round of noodling in as the JSS paper vignette was still referencing OmegaHat which the CRAN URL checker objected to. I created a quick one-off repo to serve pdf files should the need arise again, and rebuilt the vignette linking to it. No other changes.
The following section from the NEWS.Rd file has all details and links.
Changes in RProtoBuf version 0.4.28 (2026-08-21)
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.
