When new packages are released in Cydia, they will automatically appear at the top of the changes tab. This handy because it allows you to easily find new applications and tweaks for your iOS device. If this is the case when it comes to existing tweaks that have received updates. Generally the updates to existing tweaks are minor where in rare case you will get major update. Unless you have that particular tweak installed on your device, you’re pretty much left in the dark when it comes to Cydia alerting you of the new update by default.
There is a special provision that can be enabled on a per tweak basis so that it will always show you when updates occurs under the change package settings settings section. But a new jailbreak tweak called showallcydiaupdates force all Cydia packages to show their updates by default.
If you wants to know about every update regarding Cydia, then this is the perfect tweak for you. Once you install showallcydiaupdates, every Cydia package will have its show all changes switch in its change package settings section enabled.
ShowAllCydiaUpdates isn’t for everyone, but if you’re bent on keeping up with every single change in Cydia, it’s by far the easiest way to do so. You can find the tweak available for free on Cydia’s BigBoss repo.
