v4.5.32 release

v4.5.32 had five bug fixes.

Significant defects addressed

• Fixed an issue where mirror preview attempted to display a preview for rich-text elements, for which there is no ability to do so.
• Resolved an issue where the replication cache reported a healthy status despite having stopped receiving updates.
• Fixed an issue causing read-only fields to be sortable.
• Fixed an issue where revision validation occurred before a content state was set to be updated by widgets. Since validation occurred before additional changes were made, the additional changes would sometimes survive validation when they should not have.
• Resolved an issue where revisions would at times run validation without first calling beforeSave().
