Notable changes in this latest version are listed here. Some code
cleanup work and documentation editing has also been done.
256-color limit removed
Icon's X-windows interface previously limited each window to 256
colors at one time. This limitation has been removed for the TrueColor
displays provided by most modern computers. Median-cut quantization is
used to select 256 image colors when WriteImage() is called to write a
GIF file.
Library changes
As usual, several files in the Icon program library have been added or
edited. The core library files, however, remain stable.
Minor changes
* The command "icon - [args]" can now be used to execute a source
program read from standard input.
* A new "icont -N" flag suppresses embedding of an iconx path in the
generated executable
* The configuration directory has been restructured.
* Several obsolete configurations have been removed.
* The environment variables HEAPSIZE and BLOCKSIZE no longer
function as undocumented alternatives to BLKSIZE. The GNU ls
utility uses BLOCKSIZE for other purposes, leading to confusion.
* "make Install" has been changed to never delete anything. It now
creates a new directory rather than altering an existing one.
