Hi Zelig,
The version v1.1.1 is a patch version, in which I just made optimization and bug-fix. And the changelog is here:

* Fixed blocking SMS failed under some contidtion.
* Fixed clicking blacklist button show whitelist page

off-topic: I don't like N9's app manager and Store, becaue It is hard to get the apps' release note/changelog in it, even through the developers have summited their apps WITH release note every time. Too inconvenient...
