The TYPO3 core is fully compatible with both major versions of Fluid and lets you choose between version ``2.6+`` or ``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 with version ``3.0+`` you will therefore need to take one of the following actions: * Either declare a maximum version constraint for ``typo3fluid/fluid:^2`` in the root project ``composer.json`` or any dependency of the project that you control, and perform ``composer update``. * Or execute ``composer req typo3fluid/fluid:^2`` in the project directory to make the project itself declare the maximum version constraint. .. index:: Fluid, ext:fluid
