Breaking: #91562 - cObject TEMPLATE removed

See Issue #91562

Description

The cObject TEMPLATE, used for rendering marker-based templates has been removed along with the PHP class TYPO3\CMS\Frontend\ContentObject\TemplateContentObject.

The successor FLUIDTEMPLATE is widely used since TYPO3 v7, and acts as a replacement for marker-based templates.

Impact

Using TypoScript with page.10 = TEMPLATE will result in a PHP error when rendering the frontend.

Referencing the PHP class will result in a fatal PHP error.

Affected Installations

TYPO3 installation still using TEMPLATE cObject in their TypoScript.

Migration

Install the extension modern_template_building from the official TYPO3 Extension Repository at https://extensions.typo3.org/, which acts as a drop-in replacement, and also ships the cObject FILE which is highly useful for TEMPLATE cObjects.

The extension is compatible with TYPO3 v9+.
