PDF-XChange /Tools V4 Developer SDK's released !
We are pleased to announce the release of our award winning version 4 Software Developer SDK's for PDF-XChange and PDF-Tools.
Important : Please read this entire notice if you are interested in a PDF-XChange/Tools Version 4 upgrade from an earlier release - or you use the PDF-XChange Viewer SDK.
The most notable changes occur at this time to the PDF-XChange Drivers - though a very important change affects all products - we have now dropped support for Windows 9x/ME and NT and this should allow us to devote more development resources to the most popular remaining Windows operating systems - Windows 2K/XP/Vista - both 32 and 64 bit - though your Version 4 serial number will also allow you to use the Version 3 SDK should the need arise to support older Windows operting systems - but please note - no further Version 3 development will continue.
More significant feature updates will occur later this year to the PDF-XChange/PDF-Tools Library functions in version 4.5x and of course all developer's owning any of our Version 4 PDF SDK's also gain access to the PDF-XChange Viewer SDK at no extra cost !
You will also need to upgrade to Version 4 if you are using the PDF-XChange Viewer SDK freely, by virtue of the fact that you own version 3 of one of our other PDF SDK's - from Version 2.037 of the Viewer SDK - new serial numbers are required and will only be provided to those developers who actually purchased a standalone V1/2.x version of the PDF-XChange Viewer SDK itself - or licensed PDF-XChange/Tools VERSION 4 SDK owners
Version 1 or 2.x SDK existing users !
Please note that this will be the very last opportunity for Version 1 or 2.x SDK owners to acccess discounted upgrade options - from March 31st 2009 Version 1 or 2.x owners will be required to purchase a full, new PDF-XChange or Tools V4 SDK License with no discount being available.
If you own Version 1 or 2.x - please email us with your full company info, as used at the time of purchase and also your License info and we will advise how to access your upgrade options.
