TYPO3 Core

Due to #88336 redirect URLs can now be longer. However, this also affects the index_source index which includes source_host and source_path which now easily extends regular index limits:

$ typo3cms d:u -vvv
No schema updates were performed for update types:
"field.add", "field.change", "table.add", "table.change"
