Having met my objectives for Pi Presents Gapless I have decided to make it the stable version of Pi Presents and hence to retire Pi Presents Next.
I will support Pi Presents Next for another year to allow you to upgrade to Gapless.
I have added a file upgrade_1p2_1p3.txt to the Gapless repository which gives instructions and hints for the upgrade. As always I will answer queries on the [pipresents-gapless] Github or via the contact form on this site.
I hope you will enjoy using the new software as much as I have enjoyed developing it with lots of input from many of you. It is difficult to estimate the number of people using Pi Presents but I have had contact with over 500 people from a few miles from where I live to Australia.
