Official Statement:
MIUIers, we hope to focus on improving MIUI based on Android 4.4 in the future, so we've decided that MIUI V5 update for the following devices will be stopped after MIUI 4.8.8: i9100 / i9300 / MX2 / Note2 / HTC OneX / Find5 / HTC One / Nubia Z5S(mini). It's really a tough decision. If the above devices get Android 4.4 from the original factory in the future, we'll consider supporting them again. Hope you understand. Thanks.
Please someone make them aware that there is indeed 4.4.2 for note 2 released 4 months back!!
