It’s not 2026 yet, but… 
3.5.0 (Jan 2026):
• Unfortunately MacUpdater 3’s promised lifetime of “until 2026-01-01” is now over
• This is the last and final update to MacUpdater 3
• There will be no MacUpdater 4 or any continuation of the MacUpdater product from us
• Our daily maintainance has been stopped and we don’t verify updates anymore
• You can keep using this unsupported version for as long as you wish
• This version is free-to-use for everyone including “Pro” features
• The database server will be kept running until 2026-12-31
I’ll probably switch to Updatest.
