Release Notes: Memory usage and garbage collection were greatly improved, and many optimizations were made. Labels are now aligned using the rotational instead of the shiftless part of the transform. A portable CYGWIN memory limit fix was implemented. Noncyclic stokepaths are discarded to work around a bug in gs 8.71.
Release Notes: A segmentation fault in drawSphere was fixed. Recursive calls to simpson are now supported. The explicit libglapi dependency was removed. A latexmkrc example file that shows how to store figures in a subdirectory is now included.
Release Notes: Compilation without the FFTW library is now supported again.
Release Notes: Self-defined unary operators are now allowed. Formatted strings instead of real values are compared in OmitFormat. The segment(bool) function was rewritten to use the more efficient segmentlimits(bool) call. Unnecessary buffering of surface and path3 data was removed. Portability tweaks were made. References to out-of-date trembling examples were removed. Vertex-colored triangles now work again in Adobe XI. The transformation of normal vectors was fixed. PostScript extend qualifiers were added for axial and radial shading..
Release Notes: Explicitly transformed billboard labels now work correctly again. The alignment point of OpenGL billboard labels has been fixed. An "extend" parameter has been added to the axes (default true) and axes3 (default false) routines. A history recall bug has been fixed. A typo has been corrected in the documentation of the Jacobi elliptic functions sncndn.
Release Notes: Numerical resolution issues with the PRC camera orientation and viewportshift were fixed. The lighting of NURBS surfaces was fixed. The special 8192 strlen NSIS build was now correctly reinstated, with stubs, to prevent the installer from overwriting Windows PATH environment variables > 1023 bytes.
