A new version of Dotclear which I let you discover the (light) resumption of the look of the administration. In particular, many PNG images have been replaced by a vector version (SVG format), which allows to keep a good quality at any zoom level.
Note that it requires PHP 7.4 or PHP 8.0. We have tried to fix all the problems that may occur with PHP 8.1, but our testing may not have been exhaustive and we welcome any feedback on how this latest version of PHP works.
For details of the changes, see the CHANGELOG or even the repository.
