Cydia 1.1.23 was released this afternoon for iPhone, iPad and iPod Touch users who do jailbreak for any version of the iOS operating system, and in it saurik has implemented two extremely important functions that you will surely enjoy.
The first function Cydia 1.1.23 it's called Support Package Downgrade and it was designed to allow us to downgrade the Cydia application to any previous version released so far for us.
Saurik claims that a in many cases happens as a version of a Cydia launched by him to generate various problems for users and they could not return to a previous functional version, so this new function solves the problem, the downgrade being possible to any old version.
The second function of Cydia 1.1.23 is called Find Extensions for Applications and it is based on the idea of the tweak TweakHub, giving us the opportunity to discover in Cydia tweaks that were created specifically to modify the functions of certain iOS applications.
The third amendment a Cydia 1.1.23 is a new attempt to solve a problem of the application that makes it non-functional when iOS generates an automatic cache cleanup when it runs out of space available for use.
Cydia 1.1.23 is available for installation by simply opening the Cydia application.
Support Package Downgrades
All too often, I release a new package, and find out during the first few hours after release that there was a serious regression :(. Even if I pull the new version, users who upgraded do not have a way to easily downgrade. Now , not only will Cydia allow you to downgrade to the "current" version, but it also allows downgrading to any previous version that is available on the repository. Going forward, I will leave previous versions online for some time while users are able to sort out issues.
Find Extensions for Applications
This feature was directly inspired by UnlimApps, who released a Substrate extension for Cydia called TweakHub. The idea: automatically determine what applications a Substrate extension is designed to modify, and use that to provide categorized lists based on the iOS applications you have installed. This technique is exciting, as it does not rely on repositories and developers to manually tag packages (this never works out): most of this information is already picked up automatically by Cydia's "whole package index" :D. (Oh, if it isn't yet clear why UnlimApps wanted this feature: they develop a number of app-specific extensions ;P.)
Clearing Caches Could Kill Cydia
A user reported a situation where they ran out of disk space, iOS cleared their caches, and then Cydia wouldn't run.
