Contao Two Month Review May and June 2021

by Blair Winans – Community

All we did was hack away at the keyboard, but we had the stamina to run two marathons.

The hackathon--known from software and hardware development--was applied to writing documentation for Contao in June.

Yanick had written about the documentation status quo in August 2020. In that post, he had also reported that the user documentation had been machine translated into English. So the user documentation is available in German and English. You can find the developer documentation in English here.

In April, Yanick invited English-speaking users to a hackathon via the blog post to rid the English user documentation of the last machine-translated posts.

On Thursday, June 3, starting at 2:00pm, a pleasingly large number of participants showed up and we exchanged ideas in the Slack channel while various pull requests were created, reviewed and published. Shortly after 7:00pm, we ceased preliminary operations and the lights were extinguished in the repository.

We would like to extend our sincere thanks to Benedict, Daniel, Yanick, Moritz, Andreas, Blair, Stefan, Mathias, Bob, Mark, and Andrew.

There are still some tasks waiting to be corrected by you. Please help us close this ticket and leave a comment if you would like to take on a task or two.

Following the annual Contao Association General Assembly, members were given the opportunity to elect a new president. A huge and heartfelt thank you to outgoing president Nicky Hoff. A warm and heartfelt welcome to our new president Joachim Nickel.

There were also some film reels filled with new shows again. We learned interesting things about Christian Feneberg and Leo Feyer in Meet the Community and took a look behind the scenes at the Contao Show.

To note: In August 2021, the new Contao version 4.12 will be released, replacing 4.11
