 ## Version 1.5.0
 
+This release, while technically a minor release hugely expands the scope of what is possible in Panel. In particular the introduction of the new `panel.custom` module makes it trivially easy to create new JS and React based components using modern tooling, a first-class developer experience and support for compilation and bundling. We are incredibly excited to see which new components you build using this approach. This release also includes native integration with FastAPI, such that you can now run Panel apps natively on an existing FastAPI server. We also introduce a number of new components, improved the developer experience, and squashed a huge number of bugs, particularly for the `Tabulator` component.
+
+We really appreciate all the work that went into this release from 21 separate contributors. In particular we would like to welcome our new contributors @twobitunicorn, @justinwiley, @dwr-psandhu, @jordansamuels, @gandhis1, @jeffrey-hicks, @kdheepak, @sjdemartini, @alfredocarella and @pmeier. Next we want to recognize our returning contributors @cdeil, @Coderambling, @jrycw and @TBym, and finally the dedicated crew of core contributors which includes @Hoxbro, @MarcSkovMadsen, @ahuang11, @maximlt, @mattpap, @jbednar and @philippjfr.
