First major of this fork line. BC breaks relative to 1.14.1.
Removed the Db validators — Validator\Db\RecordExistsFactory and NoRecordExistsFactory. Unlike other removals in this release these withdrew live public service names: Laminas\ApiTools\ContentValidation\Validator\DbRecordExists and ...\DbNoRecordExists were registered in the validators plugin manager, so any input filter spec naming them loses them.
laminas/laminas-validator moves to require-dev; src/ no longer references it, and it remains installed regardless because laminas-inputfilter requires it.
Removed the ServiceManager v2 shims.
Constraints on sibling forks widened to accept their new majors.
