I see that Kodi 17.1 is now available in the Raspberry Pi repository at archive.raspberrypi.org for installation on Raspbian Jessie. Having been using Kodi 16.1 from archive.mene.za.net I thought I would give this a try. There are 4 problems I have noticed with the new version:
1. With the new UI I cannot use just a mouse on its own to navigate - I need to use a keyboard otherwise I can't get out of any of the settings sections. For some reason the back arrow that used to be present on the screen has disappeared. I guessed that using the backspace key on my keyboard would do the job of the old on-screen back arrow and luckily it does, otherwise I would have been stuck. Unfortunately this problem seems to be a result of the nice people at Kodi, rather than anything the RPF have done when packaging it up for the Pi.
2. No init script for automatic startup. With v16 we had an init script and /etc/default/kodi to specify some very basic startup options (which user to run as, 'nice' value etc). With 17 that seems to have been got rid of.
3. It ignores my IQAudio DAC that is attached. This is consistent with v16.0 that is available from mirrordirector.raspbian.org, but v16.1 from archive.mene.za.net gives me the option of using the DAC via ALSA, or the usual Raspberry Pi options (HDMI, analogue, HDMI and analogue). (I notice that the new version also includes an option for audio output via pulseaudio - I am guessing this is to support Bluetooth).
4. Console not restored on exit. With the 16.1 version from archive.mene.za.net (and IIRC the 16.0 version from mirrordirector.raspbian.org), if I exit Kodi the console display comes back fine. With v17.1 from archive.raspberrypi.org the console just goes blank and stays blank.
I've filed bugs for 3 and 4 - see https://github.com/RPi-Distro/repo/issues.
