Like others I have been disappointed by this first update. A bug-free receiver now has them. Some of the changes are due to Freesat requirements, with which Humax must comply.
The update ran faultlessly on the day promised by Barry. There is no choice, however, for you cannot access the original software to return to it. This means we are "stuck with" any introduced faults until Humax corrects them and/or Freesat changes its rules. And that will not happen tomorrow. A reset will not help because this simply finds the latest software edition.
One change that seems universally unpopular is the black band along the screen base when certain controls are operated. A change to HD by "OK" is another, which gives no allowance for the HB's upscaling. There is no "do not show again" choice. I have also suffered from unstable (BBC) teletext, mainly at switch-on, where the black band crashes in. Then the text is inoperable and one can have a corner picture, + some text + some EPG - all together. Certain changes to recording, including the black band, make this a wearisome process compared with earlier. The black band is slow to dissolve, causing loss of picture quality until it does so.
The HB used to be lightning fast at finding the teletext main menu. This has now changed. On two occasions it did not find this at all so I had to use the Freeview facilty!
The update was well managed, and available exactly as promised. I just hope the bugs can be as well dealt with.
