Contao Two Month Review July and August 2021

In August we welcomed a new Contao version.
To celebrate the arrival of Contao 4.12, an online session was hosted the day before the release. After a short welcome by Joachim, president of the Contao Association, Andy, core developer, gave a live insight into the new features of Contao and answered questions from the participants. Afterwards, various tables were available in the virtual room to exchange ideas on various topics. The time passed very quickly and the participants could hardly wait for the release of the new version.
In August, three security holes were closed and Contao became even more secure.

- Martin, in collaboration with Yanick from terminal42, has released a new version 2.1.0 of the RockSolid Frontend Helper. Now single elements are reloaded instead of the whole page. Furthermore, there is an edit mask in the sidebar and, last but not least, content elements can now be moved via drag & drop.
- Kamil and Yanick have made version 1.5.0 of the extension URL Redirect available to everyone. QR codes can now be created directly from the backend.
- In MM 2.2 there were major changes to the settings for the list output (CE/FE module MM list). The pagination has an individual prefix that prevents "crosstalk" between several paginations. In addition, an individual template can be selected for pagination. For sorting and pagination, it is now possible to select whether the values are transferred via slug and/or GET parameters and the keys can be individualised. Also new is a parameter list in the settings. Via a MCW, own "Key-Value-Pairs" can be created, which are available in the template via "$this->wizardParams" as an array. This allows you to further generalise a list template and control it via the backend, e.g. with labels, translations or parameters for the output or JavaScript content. Screenshots can be found on the MM-2.2 feature page.
