to images edited by Photoshop, or any image manipulation program. The same happens not only in English but as the Portuguese Wikipedia entry for image manipulation attests, even in that language, with the trademark being followed by the Portuguese verb termination -ar, yielding the word "photoshopar" (to photoshop). Such derivatives are discouraged by Adobe because, in order to maintain validity and protect the trademark from becoming generic, trademarks must be used as proper nouns. Version history Older versions Photoshop's naming scheme was initially based on version numbers, from version 0.07 (codename "Bond"; double-oh-seven), through version 0.87 (codename "Seurat" which was the first commercial version, sold as "Barneyscan XP"), version 1.0 (February 1990) all the way to version 7.0.1. Adobe published 7 major and many minor versions before the October 2003 introduction of version 8.0 which brought with it the Creative Suite branding. Notable milestone features would be: Filters, Colour Separation, Virtual Memory (1.0), Paths, CMYK color (2.0), 16-bits-per-channel support, availability on Microsoft Windows (2.5), Layers, tabbed Palettes (3.0), Adjustments, Actions, Freeform Transform, PNG support (4.0), Editable Type, Magnetic Lasso and Pen, Freeform Pen, Multiple Undo, Layer Effects (5.0), Save For Web (5.5), Vector Shapes, revised User Interface (6.0), Vector Text, Healing Brush, Spell Check (7.0), Camera RAW (7.0.1). In February 2013 Adobe donated the source code of the 1990 1.0.1 version of Photoshop to the Computer History Museum. CS (version 8) The first Photoshop CS was commercially released in October 2003 as the eighth major version of Photoshop. Photoshop CS increased user control with a reworked file browser augmenting search versatility, sorting and sharing capabilities and the Histogram Palette which monitors changes in the image as they are made to the document. Match Color was also introduced in CS, which reads color data to achieve a uniform expression throughout a series of pictures. CS2 (version 9) Photoshop CS2, released in May 2005, expanded on its predecessor with a new set of tools and features. It included an upgraded Spot Healing Brush, which is mainly used for handling common photographic problems such as blemishes, red-eye, noise, blurring and lens distortion. One of the most significant inclusions in CS2 was the implementation of Smart Objects, which allows users to scale and transform images and vector illustrations without losing image quality, as well as create linked duplicates of embedded graphics so that a single edit updates across multiple iterations.
