This distribution contains the sixth public release of the Independent JPEG
Group's free JPEG software.

Version 6a  7-Feb-96
--------------------

Library initialization sequence modified to detect version mismatches
and struct field packing mismatches between library and calling application.
This change requires applications to be recompiled, but does not require
any application source code change.

All routine declarations changed to the style "GLOBAL(type) name ...",
that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the
routine's return type as an argument.  This makes it possible to add
Microsoft-style linkage keywords to all the routines by changing just
these macros.  Note that any application code that was using these macros
will have to be changed.

DCT coefficient quantization tables are now stored in normal array order
rather than zigzag order.  Application code that calls jpeg_add_quant_table,
or otherwise manipulates quantization tables directly, will need to be
changed.  If you need to make such code work with either older or newer
versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is
recommended.

djpeg's trace capability now dumps DQT tables in natural order, not zigzag
order.  This allows the trace output to be made into a "-qtables" file
more easily.

New system-dependent memory manager module for use on Apple Macintosh.

Fix bug in cjpeg's -smooth option: last one or two scanlines would be
duplicates of the prior line unless the image height mod 16 was 1 or 2.

Repair minor problems in VMS, BCC, MC6 makefiles.

New configure script based on latest GNU Autoconf.

Correct the list of include files needed by MetroWerks C for ccommand().

Numerous small documentation updates.
