HP is releasing a new firmware for the HP Prime calculator. There are versions for both HP Primes, version G1 and G2.
In principle the release documentation informs about quality and reliability improvements - not so much about any particular additional development to the capabilities of the machine.
You can find it in hpcalc.org, in the HP Prime documentation pages:
You will need to install also the new connectivity kit to make sure it all works properly. You will need to place the upgrade files manually in the upgrades folder of the connectivity kit, since it is not yet installed in HP's FTP sites and therefore will not be found automatically by the "look for upgrade" feature of the connectivity kit. Upgrade at your own risk, then!
