The latest version of fv is version 4.0 released on November 25, 2003. Here is a list of features added (in version 3.2 and 4.0) since version 3.0 released on November 9, 2000:

fv

• Add short cut on the selection panel to allow users access fv preference quickly.
• Enhanced support for ds9 image display. User can choose to display images or plots using either DS9 or POW as the primary display tool.
• Added more XPA scripting commands for controlling fv from external processes, including create (create an image or table file or extension), export (export hdu to a Fits file or a text file), opentool (open skyview, catalog, vizier or ftools dialog panel) and preference (set up FV preferences).
• Function buttons incorported to the File Summary window to provide short cuts to common operations: 'Hist' (displays a histogram image of 1 or 2 columns in a table), 'Plot' (plots table columns), 'Table All' and 'Table Select' (The first button displays all the columns in a table, whereas the second button allows the user to select which columns to display).
• When displaying Hierarchical grouping tables, a new 'OPEN' button is available at the beginning of each row which can be used to open the corresponding group member file.
• Can display and edit images that are compressed with the new FITS 'Tile Compression' algorithm.

POW

• Allow user to save the image in POW display to one of these formats: bmp, jpeg postscript (default), png, pnm or tiff.
• Allow user to reverse the functionality of the left and right mouse buttons within the POW display via POW's Preferences settings (default: Left mouse button - control zoom, right mouse button - control brightness/contrast).
• Supports new DS9 region file format.
• Measure the distance between two points on a graph using the Ruler tool.
• Flux and centroid values for a region of an image can be calculated with the Probe tool.
