What is HotUpdate?
HotUpdate (hot update) downloads new content — levels, images, configuration, a game's script code — to the user's device when the app starts. Users get the change right away without updating the app from the store.
A test channel before going live
Each update can run in its own test channel so you can check it on real devices first. Release it to everyone once it is stable.
Instant rollback, safe packages
If a new release has a bug, roll it back immediately and users return to the stable version. Every update package is signed and integrity-checked before it is applied, so packages cannot be altered in transit.
For Cocos and Unity
The HotUpdate infrastructure works with Cocos Creator and Unity games. See how it works with each engine on the Cocos HotUpdate and Unity HotUpdate pages.
