Looks like Capture One are up to their old tricks again. I've just had an email offering 20% off the pre-upgrade to the December launch of v22, sight unseen, valid to 9th November. The claimed improvements are Panorama Stitching, high dynamic range images with HDR Merging and quick batch adjustments with Auto Rotate.
I'm signed up to their Beta programme so it might be interesting to see what the new version actually brings when the first beta is released, but given that the Black Friday discount last year was greater than the initial 20% pre-release discount, it might be prudent to wait this time. Though I thought David Grover had said in one of his recent webinars that they had learned from last year's pricing debacle and the discontent it had caused.
