-I know it's hard to believe but Nx 20 is here! There's a lot to cover in this release, so let's just dive right in.
+I know it's hard to believe but Nx 20 is here! There's a lot of great updates in this release, but look back at some of the major features from Nx 19:
+
+- Added [`nx import`][nx-import] to import existing external projects while maintaining git history.
+- Added a [generator][crystalize-command] to convert all your Nx Plugins to use inferred tasks.
+- Moved to [rspack][nx-rspack] as the default bundler for Module Federation
+- Added [file-based versioning][file-based-versioning] for Nx Release
+- Created a new [plugin for Gradle][nx-gradle] and support for [task atomization][gradle-atomizer]
+
+With Nx 20 we're keeping the momentum going and bringing some quality improvements to the overall monorepo experience as well as a boost in speed for TypeScript projects.
