<p>A few short weeks after the <a target="_blank" href="http://dirk.eddelbuettel.com/blog/2016/07/11#rprotobuf_0.4.4">0.4.4 release</a> of <a target="_blank" href="http://dirk.eddelbuettel.com/code/rprotobuf.html">RProtoBuf</a>, we are happy to announce a new version 0.4.5 which appeared on <a target="_blank" href="http://cran.r-project.org/">CRAN</a> earlier today.</p>
<p><a target="_blank" href="http://dirk.eddelbuettel.com/code/rprotobuf.html">RProtoBuf</a> provides <a target="_blank" href="http://www.r-project.org/">R</a> bindings for the <a target="_blank" href="https://github.com/google/protobuf">Google Protocol Buffers (&quot;Protobuf&quot;)</a> data encoding library used and released by Google, and deployed as a language and operating-system agnostic protocol by numerous projects.</p>
<p>This release brings support to the recently-release ‘version 3’ <a target="_blank" href="https://github.com/google/protobuf">Protocol Buffers</a> standard, used <em>e.g.</em> by the (very exciting) <a target="_blank" href="http://grpc.io/">gRPC</a> project (which was just released as <a target="_blank" href="http://www.grpc.io/blog/gablogpost">version 1.0</a>). <a target="_blank" href="http://dirk.eddelbuettel.com/code/rprotobuf.html">RProtoBuf</a> continues to supportv ‘version 2’ but now also cleanly support ‘version 3’.</p>
