vbGallery if that is the product you are talking about is not being developed at this time. Essentially vBulletin 5 brings that product to an end of life. Our core products PhotoPost Pro, Classifieds and ReviewPost all support every integration we state and the new betas we recently released add in support for vBulletin 5 and all have had numerous updates in the past couple years with lots of good features.
vbGallery which is tied so closely into the core vBulletin coding basically has to be rewritten from scratch every time vBulletin changes something. This happened quite alot look at all the different code branches. It took 18 months last time to rewrite vbGallery to support vB4 with a gold product finally reaching the shelves so to speak one year after vB4 was released. With that being said yes the only real work on vbGallery has been to support the navigation manager and fix bugs.
There are no open issues to my knowledge with vbGallery as any bugs we investigated where fixed. I see one issue from you almost 15 months ago where we asked for information to assist and investigate and you never replied. You never followed through with the information we asked for therefore we never looked into your sites issue.
