Standalone users should have received a pretty important update today over air (gets downloaded at launch if you have autoupdate enabled), this applies to Toribash versions 5.41 to 5.43.
The update contains a bunch of updates for lua data files (primarily news and events) and a popup about 5.43 being available for those still on 5.41 or 5.42. Popup will likely annoy you, though that's kinda the purpose.
All versions before 5.43 will stop working properly starting next month, so make sure you migrate in time.
