------------------------------------
-
-The prior hook parameter/variable :php:`fields` is now available via
-:php:`$event->getColumnsToRender()`. The actual record data
-(previously :php:`$this->recordList`, submitted to the hook as its object
-reference) is accessible via :php:`$event->getHeaderRow()`.

-Migrating :php:`customizeCsvRow`
---------------------------------
-
-The following prior hook parameters/variables have these substitutes:
-
-:php:`databaseRow`
-    is now available via :php:`$event->getRecords()` (see note below).
-:php:`tableName`
-    is now available via :php:`$event->getTable()`.
-:php:`pageId`
-    is now available via :php:`$event->getId()`.
-
-The actual record data
-(previously :php:`$this->recordList`, submitted to the hook as its object
-reference) is accessible via :php:`$event->getRecords()`.
-
-Please note that the hook was previously executed once per row retrieved
-from the database. The PSR-14 event however - due to performance reasons -
-is only executed for the full record list after database retrieval,
-thus allows post-processing on this whole dataset.
