v4.2.28.2 release

v4.2.28.2 had one improvement and three bug fixes.

Significant improvement

• The task ScheduleFilter no longer increments the run count when it is not running on the configured task host.

Significant defects addressed

• Corrected an issue in which a site's theme caused the content edit page for creating a Page to display incorrectly.
