Removed "valid for" quarter and year selections due to confusion over their function. The Course Catalog search displays any course that is valid, which means a department is able to offer it, not necessarily that it is offered for the current registration quarter. This behavior is correct, but potentially confusing to students. Also altered explanitory text referring users to the Time Schedule for current availability.
Display of advanced search options panel is now remembered while searching during the current and future sessions.
Added placeholder attribute values to text input fields for added usability in HTML5-aware web browsers.
