The hangar does not invent a patch calendar. It only repeats what the public card still prints.
Hangar recheck
I opened the Google Play listing again. Name, developer, 4.2 from 2.32M reviews, 100M+ installs, Teen with Violence and In-Game Purchases, ads, in-app purchases, Android and Windows — all still on the card. Update date still reads 31 May 2021. Size and version string still absent.
Date printed on the listing as “Updated on”
What’s new on the card: Gunship Raider added; Episode 32 added; 2x Reward Stages on Custom Missions changed; miscellaneous bug fixes. That block has not been replaced by a newer store changelog as of the hangar recheck.
If JOYCITY ships a later build, the store will show it. Until then this page stays honest about the stamp.
