Libpng 1.0.6j - May 4, 2000
Libpng 1.0.7beta11 - May 6, 2000
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
This is a public release of libpng, intended for use in production codes.
Changes since the last public release (1.0.6):
version 1.0.6d [April 8, 2000]
Changed sprintf() to strcpy() in png_write_sCAL_s() to work without STDIO
Added data_length parameter to png_decompress_chunk() function
Revised documentation to remove reference to abandoned png_free_chnk functions
@@ -15,36 +13,33 @@ version 1.0.6d [April 8, 2000]
Renamed makefile.ibmvac3 to makefile.ibmc, added libpng.icc IBM project file
Added a check for info_ptr->free_me&PNG_FREE_TEXT when free'ing text in png.c
Simplify png_sig_bytes() function to remove use of non-ISO-C strdup().
version 1.0.6e [April 9, 2000]
Added png_data_freer() function.
In the code that checks for over-length tRNS chunks, added check of
info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann)
Minor revisions of libpng.txt/libpng.3.
Check for existing data and free it if the free_me flag is set, in png_set_*()
and png_handle_*().
Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED
is defined.
Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c
and mentioned the purposes of the two macros in libpng.txt/libpng.3.
version 1.0.6f [April 14, 2000]
Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data.
Add checks in png_set_text() for NULL members of the input text structure.
Revised libpng.txt/libpng.3.
Removed superfluous prototype for png_set_itxt from png.h
Removed "else" from pngread.c, after png_error(), and changed "0" to "length".
Changed several png_errors about malformed ancillary chunks to png_warnings.
version 1.0.6g [April 24, 2000]
Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined.
Relocated paragraph about png_set_background() in libpng.3/libpng.txt
and other revisions (Matthias Benckmann)
Relocated info_ptr->free_me to restore binary compatibility with libpng-1.0.5
(breaks compatibility with libpng-1.0.6).
Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
png_ptr members to restore binary compatibility with libpng-1.0.5
(breaks compatibility with libpng-1.0.6).
version 1.0.6h [April 24, 2000]
Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
This is a temporary change for test purposes.
version 1.0.6i [May 3, 2000]
Rearranged some members at the end of png_info and png_struct, to put
unknown_chunks_num and free_me within the original size of the png_structs
and free_me, png_read_user_fn, and png_free_fn within the original png_info,
because some old applications allocate the structs directly instead of
using png_create_*().
Added documentation of user memory functions in libpng.txt/libpng.3
Modified png_read_png so that it will use user_allocated row_pointers
if present, unless free_me directs that it be freed, and added description

Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
version 1.0.6j [May 4, 2000]
Overloaded png_read_init() and png_write_init() with macros that convert
calls to png_read_init_2() or png_write_init_2() that check the version
and structure sizes.
Restored original shared library so-number pattern (2.x.y.z)
In png_set_text, check if old application had allocated the png_text structure;
if so, only allow one text chunk to be processed to avoid memory overrun.
Added PNGAPI macro, and added it to the definitions of all exported functions.
