Enable Improved Caching of Org Schema (Critical Update)

Improved caching of org schema resolves known issues with version-specific object and field handling.

Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions.

Why: This critical update fixes known bugs by improving internal systems that define and cache org schema, including standard objects, custom objects, and their fields. The documented behavior of your org’s schema remains unchanged. The update fixes bugs where the documentation doesn’t match the known behavior. This update also resolves rare, intermittent cases where undocumented object types are visible in Apex describe result methods or where version-specific schema details are improperly reused.



This update was briefly available in Summer ’19 and described in the release notes, but was removed prior to customer release. This is the first release this update has been available for activation.
