The dev and stable releases are based on the same code base.
The difference between the stable and dev builds are
- Stable builds are flashed on devices we sell from our eShop
- The builds we have are test - dev - stable
- Test builds are what our testing team gets on their devices
- Once they complete the testing and release the build it goes on to all users as dev build
- After running for a couple of days on user devices the same builds are again tested and if no issues are detected the build is now sent out OTA for users who purchased from eShop
- New eShop devices also get flashed with these ‘three times’ tested builds
- That also means the stable builds frequency will be slower compared to dev builds
Hope that clarifies the difference.
