Important: #90285 - Fresh installs without constraint for typo3fluid/fluid will get version 3.0+¶
Projects which have no dependencies that add a constraint on the maximum allowed version of Fluid
will in the future download and install
The TYPO3 core is fully compatible with both major versions of Fluid and lets you choose between
3.0+ by constraining your project dependencies. However, some projects based
on TYPO3 may contain Fluid templates or dependencies which are not compatible with Fluid 3.0, yet
neglect to declare a maximum version constraint for Fluid - since until the release of version 3.0,
the only/highest major version was 2.6 and
composer install would therefore always select version
^2.6 as it was the only option.
If your project has no maximum version constraint and contains Fluid templates which are incompatible
3.0+ you will therefore need to take one of the following actions:
Either declare a maximum version constraint for
typo3fluid/fluid:^2in the root project
composer.jsonor any dependency of the project that you control, and perform
composer req typo3fluid/fluid:^2in the project directory to make the project itself declare the maximum version constraint.
