Contao 3.5.30 is available
by Leo Feyer – Announcements
Contao version 3.5.30 is available. The bugfix release fixes a problem with displaying multi-day events if the "shortened view" option has not been enabled and a certain period is selected.
Due to a change in Transifex, it seems no longer possible to download language files with the Transifex client without authentication. We have therefore re-added the language files to the Git repository, which might require to adjust existing build and deployment processes.
The change does not affect installing Contao from the .zip or .tar.gz files via download.contao.org.
