 ## Highlights
 
+* Introduce `BenchmarkDotNet.Diagnostics.dotMemory` [#2549](https://github.com/dotnet/BenchmarkDotNet/pull/2549): memory allocation profile of your benchmarks using [dotMemory](https://www.jetbrains.com/dotmemory/), see @BenchmarkDotNet.Samples.IntroDotMemoryDiagnoser
+* Introduce `BenchmarkDotNet.Exporters.Plotting` [#2560](https://github.com/dotnet/BenchmarkDotNet/pull/2560): plotting via [ScottPlot](https://scottplot.net/) (initial version)
+* Multiple bugfixes
 * The default build toolchains have been updated to pass `IntermediateOutputPath`, `OutputPath`, and `OutDir` properties to the `dotnet build` command. This change forces all build outputs to be placed in a new directory generated by BenchmarkDotNet, and fixes many issues that have been reported with builds. You can also access these paths in your own `.csproj` and `.props` from those properties if you need to copy custom files to the output.
