Important: #89720 - Only TypoScript files loaded on directory import

See Issue #89720

Description

With Issue #82812 the new @import syntax for importing TypoScript has been added.

Among others the change was documented to only load *.typoscript files in case a directory is imported. However, this was not implemented as such and all files where imported instead.

The code has been fixed to only load *.typoscript files on directory import. To load other files besides *.typoscript a suitable file pattern must be added explicitly now:

# Import TypoScript files with legacy ".txt" extension
@import 'EXT:myproject/Configuration/TypoScript/Setup/*.txt'
