v1.30.1

Added

• Every custom column is now filterable. A filter control is generated
  automatically for each one - a dropdown offering All plus the column's
  own values for a dropdown-type column, or a substring text box for a
  text-type column - and it appears or disappears as you create or delete
  columns. It combines with every other filter (search, year, etc.) the same
  way they combine with each other.

v1.29.0

Added

• A "Check for updates" button in the Info dialog. It forces an immediate
  release check instead of waiting for the once-a-day background check, and reports
  the result inline - either that a newer version is available (with a download link
  and the banner) or that you are on the latest version. Backed by a new
  ?force=1 parameter on /api/update-check that hits GitHub synchronously and
  bypasses the daily throttle.
