+In our part of the world, summer has already started and everyone is preparing for their summer vacations. But we are still busy…
+
+While we are working hard on the next big Kirby 4 release [(Kirby 4 Alpha
+3](https://github.com/getkirby/kirby/releases/tag/4.0.0-alpha.3) was released 2 week ago), Kirby 3 is still under active development. Also two weeks ago we released [Kirby 3.9.5](https://github.com/getkirby/kirby/releases/tag/3.9.5) with many bug fixes and some improvements, and the next Kirby 3 version is already in the works.

+
+"So yes, as you might have noticed by now, I am a big fan of Kirby, especially because it allows you to solve common problems in a straightforward way, making my life as a designer and developer so much easier, but also because my clients have always been very happy with the content editing experience in the backend – without exception. Kirby enables successful projects." (from [Starting A New Kirby Project](https://matthiasott.com/notes/starting-a-new-kirby-project))
