I hesitated to inform everyone that 1.5.6 was out in December of 2018, because several bugs were found in it after its release.  All bug fixes are not done in 1.5.6a, so it should be ready to rock and roll!

If you are unsure of the mods that might be installed, you will probably want to fill out our Request For Quote Form PRIOR to placing your order, so we can give you a list of what you have installed so you can determine if you still want/need these zen cart modifications or whether they have been updated to work with the latest version you are upgrading to.
