Cydia on jailbroken iPhone or iPad is very crucial and it is important to run the latest version at all times. Jay Freeman, also known as Saurik among the jailbreak community members, released the latest Cydia update, version 1.1.25 and 1.1.26 for iOS 9 and iOS 9.0.2. The free update is available for download right now and it is highly recommended that the jailbreak users get the new software as soon as possible.
Apple released the latest software, iOS 9.1, which patched up the uphill struggle of the jailbreaking community, Pangu. The new software was expected to be released in November, but the early rollout only means Apple is doing everything it can to keep its software bug free. The iPhone-maker rolled out iOS 9.0.1 and iOS 9.0.2 in a short period of just one month to address the major pressing concerns of its users and now released the first major software update to its precious iOS 9.
According to Freeman's changelog on Reddit, Cydia 1.1.25 installs new tweaks in a different location, freeing up more space on your iPhone's available storage. Below is the entire changelog note explained by the man himself:
According to Redmond Pie, anyone with a jailbroken iPhone or iPad must go ahead and update to the latest Cydia right away. To do so, launch Cydia from your device, tap on Reload located on the top right and wait for the update. Once you get a prompt for "Essential Upgrade," tap on "Complete Upgrade" to get the latest version of Cydia.
If you choose to update alternatively, simply search for Cydia Installer within Cydia and manually update the app.
