Folks I know this will come as a bit of a shock to some of you, but the TDS software line is to be discontinued, effective immediately. This is one of the biggest decisions I've ever had to make as the director of DiamondCS, so it was not a decision that was taken lightly, but a decision that will ultimately benefit you, our customers. For a full understanding, please read on.

So why on earth did we make a crazy decision like this?!? I hear you ask..
at least I get a free Process guard out of it

it is a pity to see the tool go (even the TDS4 is on the block), the reasoning is sound as to why..
