Changes in 0.91 (2 May 95)
|
||||
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
|
||||
- Document the memory requirements in zconf.h
|
||||
- added "make install"
|
||||
- fix sync search logic in inflateSync
|
||||
- deflate(Z_FULL_FLUSH) now works even if output buffer too short
|
||||
- after inflateSync, don't scare people with just "lo world"
|
||||
- added support for DJGPP
|
||||
|
||||
Changes in 0.9 (1 May 95)
|
||||
- don't assume that zalloc clears the allocated memory (the TurboC bug
|
||||
was Mark's bug after all :)
|
||||
@ -10,6 +19,7 @@ Changes in 0.9 (1 May 95)
|
||||
- document explicitly that zalloc(64K) on MSDOS must return a normalized
|
||||
pointer (zero offset)
|
||||
- added Makefiles for Microsoft C, Turbo C, Borland C++
|
||||
- faster crc32()
|
||||
|
||||
Changes in 0.8 (29 April 95)
|

zlib 0.9 is a beta version of a general purpose compression library.
|
||||
zlib 0.91 is a beta version of a general purpose compression library.
|
||||
|
||||
The data format used by the zlib library is described in the
|
||||
file zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
|
||||
files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
|
||||
in ftp.uu.net:/pub/archiving/zip/doc.
|
||||
|
||||
All functions of the compression library are documented in the file
|
||||
zlib.h. A usage example of the library is given in the file example.c
|
||||
which also tests that the library is working correctly.
|
||||
To compile all files and run the test program, just type: make test
|
||||
|
||||
The changes made in version 0.9 are documented in the file ChangeLog.
|
||||
The main changes since 0.8 are:
|
||||
- don't assume that zalloc clears the allocated memory
|
||||
- let again gzread copy uncompressed data unchanged (was working in 0.71)
|
||||
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
|
||||
To compile all files and run the test program, just type: make test
|
||||
(For MSDOS, use one of the special makefiles such as Makefile.msc.)
|
||||
To install the zlib library (libgz.a) in /usr/local/lib, type: make install
|
||||
To install in a different directory, use for example: make install prefix=$HOME
|
||||
This will install in $HOME/lib instead of /usr/local/lib.
|
||||
|
||||
The changes made in version 0.91 are documented in the file ChangeLog.
|
||||
The main changes since 0.9 are:
|
||||
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
|
||||
- Document the memory requirements in zconf.h
|
||||
- added "make install"
|
||||
- added support for DJGPP
|
||||
|
||||
On MSDOS, this version works in both large and small model. However
|
||||
small model compression works only for small values of MEM_LEVEL and
|
||||
WBITS (see zutil.h). Small model decompression should work up to WBITS=15.
|
||||
This version of zlib does not support small or medium model with far
|
||||
allocation of big objects.
|
||||
small model compression works only for small values of MAX_MEM_LEVEL
|

|
||||
to MAX_WBITS=15. This version of zlib does not support small or
|
||||
medium model with far allocation of big objects.
