|4.3.2||29 March 2016||Fixed a bug in writing ASCII data.|
|4.3.1||26 January 2016||Export for SeisOpt® @2DTM now uses only the X coordinates of sources and receivers. If your survey coordinates are not aligned to the X-axis, you should apply a new survey geometry using a rotated coordinate system to align source and receiver coordinates closely with the X-axis. SeisOpt® @2DTM cannot use a Y coordinate.|
|4.3.0||20 August 2015||Demotion of the IEEE Float binary data format to 11th on the list (readtype=11). 32-bit Intel Float is now at the top of the list, readtype=0. Added reading of raw 64-bit Intel double-precision float and 32-bit IBM float. Loading a new 2D image in-place now keeps the former axis labels and other plot properties, if the new data set is the same size as the old.|
|4.2.2||5 June 2015||New ShakeMap MMI color table for plotting PGV maps. Added exp method to take the base-10 exponential of every value.|
|4.2.0||14 July 2014||New image output capabilities: PNG; JPEG; or full-resolution PostScript of the current view; or of all planes in a volume. Optional dark-background PNG or JPEG images.|
|4.1.0||10 July 2014||Improvements to PostScript page scaling.|
|4.0.1||30 June 2014||Re-enabled multithreading (removing the MacOS Tiger workaround); compiled under Java 1.6.|

interactive pole-zero filter design program with ``|
|3.6.6||16 November 2009||New tsquaregain method.|
|3.6.5||23 July 2009||Adjustments to reading of SEGY (reads Intel float trace samples) and SAC files.|
|3.6.2||30 December 2008||Interface additions and adjustments including: one-button saving and loading of JRG Packs holding data, headers, and all plot parameters and picks; user can't close last plot, leaving program running with no interface; one-click undo of last pick made, refresh of plot, and resampling of pick text.|
|3.5.1||15 June 2007||WriteASCII now writes a single column; reading and writing of SAC files (Intel and IEEE binary); reading of Intel Pentium float binary; differentiate, decimate, and 2-d line source to 3-d point source conversion (from Vidale et al., BSSA, 1985) methods added.|
