2.1.1

• Restored (V2): the sitewide expired-license admin notice is back, exactly as in 2.0.1. 2.1.0
  had removed it, but the updater is shared by many products and that change was meant for one
  product only, so it was reverted. Both notices (no license key, expired license) behave as they
  did in 2.0.1, including the one-week snooze
• 2.1.0 was tagged briefly on 2026-09-15 and then withdrawn (tag and release deleted), so there is
  no 2.1.0 to install. Sites never received it
