So, this build has only five changes: some improvements to error message handling (well tested), a change to the keyboard for the Search panel (I have not even tried this, nor have I looked at the code for it: chpwn made the change, and only tested it on his firmware revision,
AFAIK), some modifications to localization (a couple wording changes in Chinese, in particular), a fix for a memory leak in the web browser (that leaks memory so slowly you will never notice unless you are me, but for what it is worth this is well tested), and:
...a drastic modification to the mechanism for "stashing" (where all of your files are rearranged directly after a jailbreak), a change I made a day and a half ago and tested for two minutes. I put this change into a build for comex, who recently made comments about an improved platform for installing jailbreak filesystem changes. I spent a bunch of time thinking about how these changes could go in and not break any existing installations, but I cannot test these corner cases well and so far no one other than me (for two minutes) has tested "1.1.2" on an "already jailbroken device": all testing has been "during a jailbreak install".
This version, therefore, was likely never going to hit the index as a general update for users as a "release": if I were going to do that, I'd make certain the iOS 5 fixes were in first (there were some irritating changes to the web browser on iOS 5 that make things like Cydia's custom User-Agent header not work: this bug is pretty critical for iOS 5 support, and has not been examined yet).
