Notable changes in version 9.4.3: The system-specific Icon configurations have been reorganized and renamed. The several BSD configurations have been merged into one. The macintosh configuration now supports the loadfunc function. A new porting guide has been written, and a new posix configuration has been added as a starting point in constructing new ports. The core library files remain stable. Notable changes include: - procs/dijkstra new procedures implement Dijkstra's control structures - procs/html add procedure for canonicalization of paths - procs/matrix2 new procedures for matrix manipulation - procs/nestlist new procedures for representing nested lists as strings - procs/printf add %e format and fix a rounding problem - progs/noise new program for producing a random bitstream - progs/unclog improve logic for combining adjacent entries - gprogs/dlgvu improve coverage map; allow altitude in GPS data - gprogs/gallery faster thumbnail loading for JPEG images - gprogs/img many new features - gprogs/sier better color choices - gprogs/trkvu accept GPS track logs with altitude as the last field The undocumented save function, which only worked on a few platforms, has been removed.
