RProtoBuf 0.4.27 on CRAN: Upstream Adjustment

Sun, 26 Apr 2026 13:07:00 CDT

A new maintenance release 0.4.27 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 adjusts to a change upstream. Luca Billi noticed that upstream removed some fields from FieldDescriptor, filed and issue and followed up with a spotless PR. No other changes.

The following section from the NEWS.Rd file has all details and links.

Changes in RProtoBuf version 0.4.27 (2026-04-26)

Adjust to FieldDescriptor API changes in ProtoBuf 3.4 (Luca Billi in #114 fixing #113)

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.
