Breaking: #88744 - Database fields related to CSS Styled Content removed

See forge#88744

Description

CSS Styled Content was superseded with Fluid Styled Content in TYPO3 v7, and support was dropped with TYPO3 v9. TYPO3 Core still shipped with some database fields that were kept to easy manual migration for specific values in these fields.

These database fields within the database table tt_content have been removed.

• tt_content.spaceBefore (now used via space_before_class)

• tt_content.spaceAfter (now used via space_after_class)

Impact

Accessing the database fields with a custom SQL query will result in SQL errors or empty values.

Affected Installations

TYPO3 installations from earlier TYPO3 versions (prior to v8) that still have CSS Styled Content in use or adopted to migrate the fields to still render via CSS Styled Content.

Additionally, TYPO3 installations that mis-used the database fields for other purposes but still rely on the presence of the database fields.

Migration

If the database fields still contain value that hasn't been migrated, it is possible to re-add these database fields in a custom extension.

It is recommended to switch to Fluid Styled Content rendering or custom content types with custom additional fields.
