+<h1>R Tools for Visual Studio</h1>
+
+<p>Hello R Tools for Visual Studio user!</p>
+
+<p>
+We are pleased to announce a new preview release of R Tools for Visual Studio: 0.5.1.</p>
+
+<p><a href="https://aka.ms/rtvs051_update">Download RTVS 0.5.1 now!</a></p>
+
+<h2>What's New in 0.5.1</h2>
+
+<p>RTVS 0.5.1 is a minor update that fixes an R Interpreter stack limitation
+that affected a small number of our uses. We have increased the stack size limit
+to 20MB in our R Interpreter (Host) process to be in line with the defaults of
+what R currently uses.</p>
+
+<h2>What's New in 0.5</h2>
+
+<p>RTVS 0.5 adds two significant features: plotting enhancements and SQL
+integration. We’ve created two new help topics to get you up to speed quickly.
+Be sure to look at the feature videos for those help topics as well to get an
+overview of the feature.
+
+<ul>
+    <li>Plotting - multi-window plotting, and graphical plot history
+    <li>SQL tooling - SQL editor with IntelliSense, writing and running R code on SQL Server 2016
+</ul>
