Episode 100
This is issue 100 of our Kosmos newsletter 🎉, nearly 10 eventful years after our very first issue on July 1, 2016. At that time, Kirby was about 2 years into version 2. Shortly before, Kirby had begun to grow beyond a purely one-man show, but still years away from becoming the Content Folder GmbH & Co. KG we are today.
What a ride since our “humble” beginnings, so let's take a moment to celebrate literally hundreds of Kirby releases, satellite products like the CLI, StatiCache, or KQL, a little extra "kosmos" of internal tools (our hidden champions), and last not least, a wonderful, engaging community. We are really looking forward to meeting as many of you as possible in September.

Kirby 5.3.2
True to the motto “Where you plane wood, chips will fall”, Kirby 5.3.0/5.3.1 not only included numerous bug fixes, but sadly also introduced some of its own, particularly in user handling, "inherited content", and some visual regressions. But Kirby 5.3.2 is here to the rescue. If you already updated to Kirby 5.3.0 or 5.3.1, we recommend updating to this latest version.

The Email Manager plugin for Kirby allows you to build flexible contact forms efficiently. The plugin emphasizes flexibility and a developer-friendly workflow.
