Previously, the Message/Text of event (regex) filter on the Event Console Events screen returned no results, even for patterns that should clearly match. For example, filtering with connection would show nothing despite events with text like Connection Error being present.

This has been fixed. The filter now correctly performs case-insensitive regex matching against event messages.
