The new release which went wrong last week has been fixed and is now live and seems to be working ok. There were some teething problems yesterday and today where it wouldn't show whether a service was open or closed correct, but I think I've successfully fixed this as well, although it might be minute out or at change over times.
Technically this quite a bit improvement as the way that openings are stored and the calculation for determining whether they are open has been greatly improved. I've been working on this for about two months, so I'm glad it's finally live.
At the moment only Waitrose have any special openings for the Christmas and New Year period. Hopefully I shall add some more in the next few days.
In the New Year I will continue my work on form to allow users to submit and edit the information in a wiki style. Please let me know if you spot any errors on the site, thanks.
