Jay and Thomas:
Thank you for your feedback. We are in the process of defining the next generation of the product and will take your feedback into account as part of that process. We are definitely trying to find a better way to provide more notice.
Regarding the PX dispatch support in 7.0 -- at this point we must await a response from engineering to determine what sort of solution, if any, is available. Going forward, SSE2 is our commitment for the base 32-bit library (SSE3 for the base 64-bit library). since SSE2 is supported by virtually all the processors produced by Intel and AMD since about 2003.
Please note that as a licensed IPP developer you can continue to use the 6.1.6 library indefinitely within your product, even if you are also using the 7.0 product. Obviously, this means you may have to build a "legacy" version of your product(s) to satisfy some of the pre-SSE2 systems out there -- not necessarily an ideal solution for all --to paraphrase a popular quotation, you cannot satisfy all the people all the time, which is a crossroad we are having to deal with.
