Please note new version

I am the happy owner for several months of this transceiver that works to my complete satisfaction.
We can do without it and use it as I did before a yn622c mounted on the camera, but then you go through the camera menus for settings.
a new version comes out, which would improve including the scope of the craft, stability bonds, etc ..
This is a new circuit, so no opportunity to "upgrade" an older model by software.
Personally, my "old" 622c tx suits me.
But under the adage "who can do more can do less" better check that we buy the new model.
The new models are manufactured since 15.12.2015 and it seems that the only way to distinguish the old model is the new date of manufacture (see the sticker in the battery compartment)
