Jailbreak developers can now mark their tweaks as iOS 8.3 compatible.

Until now the developers were not having the ability to mark their jailbreak tweaks, since saurik want to ensure the stability of the TaiG iOS 8.3 jailbreak.

During installation from Cydia you might have seen a warning message that reads, "This product is not currently certified to be compatible with your device." This message appears on all paid tweaks in Cydia, which means they are not enabled for iOS 8.3.

TaiG has recently rolled out an update, version 2.1.2, to its untether jailbreak tool with support for Cydia Substrate and addresses all the error found in the previous release. Besides, the TaiG 8.1.3-8.x Untether version 2.1.2 package available in Cydia as an update.

With the stable release of the TaiG jailbreak utility, Cydia is now officially open for iOS 8.3 compatible tweaks, and users can purchase Cydia tweaks that are updated.
