SARK-110: New firmware version v0.8.1 available

This is a major firmware update with lot of new functionality, enhancements and fixes. The new version is available in the Firmware area.
For users that already installed any of the v0.8.0.x beta drops, this release is nearly equivalent to the latest v0.8.0.20 with just a couple of minor corrections.
The user's manual (english version) has been also updated and available in the Documents area. Other language versions will be available soon.
It is my wish for 2014 focusing my development efforts on the SARK Plots client software, specifically on post-processing capabilities. This does not mean that firmware will not be opened to enhancements, but I believe that there is a lot of room for improvement in the client software such as measurement of transmission line parameters, tools for calculating matching networks for RFID antennas, improved calibration means, etc. Anyway, I am glad to hear suggestions for enhancements from users.
Following is the release notes for this version:
