Visture released the update 20131120 (date of compiling), which is confusingly named 20131206 (date of publishing) on their web page and readme.
However, the actual file is VISTURE V97 HD FW 20131120.zip
It is better to google for mirror as it is nearly impossible to download from the official link as usual.
- fix for HDMI to TV which failed to work on some units
- fix for an issue preventing the tablet to boot while charging
Other than that, no dramatic change in any aspect. I did a clean re-install of the tablet for the occasion and found it as stable as before, but no visible boost in Wi-Fi or overall performance.
Other news from Visture:
- Android 4.4 should be expected soon for their RK3188. All the value of this information is in the meaning of "soon", of course.
- New i10 tablet is coming soon. Based on MTK8389, it's more like a 10.1" smartphone, with 3G, GPS and even FM Radio onboard: http://visture.com/more.asp?id=15
Apart from the screen size, specs looks similar to the Freelander PX2.
