Users of Acrobat Pro Extended’s 3D features are now directed to Tetra4D, who have taken over development and support of the 3D engine from Adobe. What happened to Pro Extended? The answer: Every couple of years when Adobe puts out a full new release of Acrobat, there are a few different editions to choose from and new features to study to decide which of them you’re going to get… This year is no different – the Acrobat X (10) family is available in the form of the free Reader, the familiar Standard and Pro, and a brand new Suite edition that bundles Acrobat Pro together with Photoshop, Captivate, and three other Adobe products in a package to deliver complete business communications.Ĭonspicuously absent is the “Pro Extended” edition from version 9, which used to be called Acrobat 3D.
