This file lists changes in the cslib libraries in reverse chronological
order, beginning with the most recent version and continuing backward to
version 1.2, which was the first version announced as available:
Version 3.1 (27-Feb-95, Eric Roberts):
o Fixed several bugs in the handling of the mouse code for the
Borland/PC version.
o Changed identifier names in the exception.h file to avoid conflicts
with the TURBO compiler.
o Fixed a bug in the black-and-white monitor creation code for the
THINK/Mac version.
o Corrected an incompatibility in the graphics.c implementation that
failed with the THINK C 7.0 headers.
Version 3.0 (25-Oct-94, Eric Roberts):
o Includes an extensively revised extgraph.h interface that supports
color graphics and mouse clicks.
o Incorporates the version 2.0 change so that the erasing model is
equivalent to painting with white paint. The model from the
version 1 releases was difficult to understand.
o Extended implementation to take better account of variations in
display size.
o Restructured the export directories to make it easier to import an
entire system.
o Changed the UNIX/XWindows version Makefile so that it automatically
configures the compilation for System V or BSD systems, as
appropriate.
o Improved the documentation, adding several new README files and
related papers.
Version 2.0 (not released outside of Stanford):
This version was used at Stanford on an experimental basis during
the summer of 1994. The major change was the use of offscreen
memory to maintain the screen image rather than a display list;
because this change affects the interface model by changing how
erase mode works, this revision was considered to be an interface-
level revision, giving rise to the new major version number. By
the end of summer, this version had already been superseded by
Version 3.0 and was therefore never released outside of Stanford.
Version 1.8 (2-Aug-94, Eric Roberts):
o Improved documentation and structure
o Released version to aw.com
Version 1.7 (20-Jun-94, Eric Roberts):
o Fixed minor bug in strlib.c; the bug affected only clients using
garbage collection, which is not publically released.
Version 1.6 (19-Apr-94, Eric Roberts):
o Restructured library directories
o Added basic subdirectory containing minimal version
o Minor cleanups to code and comments
Version 1.5 (1-Jan-94, Eric Roberts):
o Included the gcalloc.h interface so that the genlib.c file is
standard
o Libraries are now safe for garbage collection
Version 1.4 (20-Oct-93, Eric Roberts):
o Added number/string conversion functions to strlib.h
o Fixed definition of TRUE/FALSE on systems that already define bool
o Made minor corrections to comments in several libraries
Version 1.3 (23-Sep-93, Eric Roberts):
o Made major changes to graphics.h interface to correspond to text
o Tightened up strlib.h
o Added GetLong to simpio.h
Version 1.2 (6-Aug-93, Eric Roberts):
o Released to anonymous FTP on labrea.stanford.edu.
