Contao 4.13.6, a new version of the Contao open source CMS, has been released.

As always, this release contains all the improvements of 4.9.31, which this time especially includes performance improvements. The 4.13.6 goes one step further and also contains an improvement for the {{date::Y}} insert tag, which is very often used in the footer or similar, and can now be cached until the end of the respective year, thus avoiding unnecessary ESI requests. In addition, various migrations were improved, which could cause missing database optimizations depending on the situation. Furthermore, a potential SQL deadlock in the search implementation has been fixed, so an update is strongly recommended, otherwise connections to the database could be kept open unnecessarily.
