In this issue, our main focus will be on Kirby, and we want to take you with us on our journey towards Kirby 3.6 right from the very beginnings. With Kirby 3.5.7 comes an important security release (see below). But of course, you will also find other interesting links from our industry.

Kirby 3.6 Alpha

Kirby 3.6 is probably the most important release since we published Kirby 3 almost 2.5 years ago. With this new version, we lay a strong foundation for Kirby's future and all the highly-requested features which are currently not so easy to implement. Kirby 3.6 will make Kirby more stable, more extendable, and much more fun for years to come.

Are you ready? Here are some appetizers:


Fiber is Kirby's brand-new backend architecture for the Panel. It greatly simplifies the Panel and Panel plugins, making it easier to implement new features and write all sorts of plugins for the Panel.

Panel areas & extensions

Our new Fiber architecture splits the Panel in areas: site area, users area, settings area, etc. You can now create your own areas and build entire applications on top of the Panel. Areas replace the previous views.

Panel Theming

Extensive use of CSS variables in the Panel make it much easier to create themes for the Panel.

Navigation options

Navigating between pages in the Panel is now completely customizable via blueprint.


Cardlets are a new layout type for Panel sections and the pages and files fields. They fill the gap between the list and card layouts.

Custom file type extensions

Easily extend Kirby's built-in file support with custom file and mime types.

Modern image formats

Our image processing API now supports WebP and AVIF as better alternatives for JPEG/PNG images.

Of course, there's a lot more to discover! Want to know more or play with the new features right now? The full list of features is on our new 3.6 Microsite. Or directly download the 3.6 Alpha developer preview and start exploring.

Kirby 3.5.7 security release

Kirby 3.5.7 comes with a whole new set of fixes and improvements. Note that this version is also a security release, so we strongly recommend you update to this version.
