Some features notably missing from this list include language support. In particular, the Kindle Paperwhite has enhanced support for Chinese and Japanese. It's not clear why Amazon left some features out of the update, but on the upside the KT is getting features which will extend the lifetime of the gadget.
It might not be available anymore in most markets but clearly the Kindle Touch has not been forgotten by Amazon.
You can dowbnnload the update from the Amazon website.
