+Changes since the last public release (1.2.36):

-version 1.2.36 [May 6, 2009]
+version 1.2.37beta01 [May 14, 2009]
+  Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36.  The
+    memset() was using "png_ptr->rowbytes" instead of "row_bytes", which
+    the corresponding png_malloc() uses (Joe Drew).
+  Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri)
+  Updated some of the makefiles in the scripts directory (merged with
+    those in libpng-1.4.0beta57).

-  Revised comments in png_set_read_fn() and png_set_write_fn().
-  Revised order of #ifdef's and indentation in png_debug definitions of png.h
-    bug introduced in libpng-1.2.34.
-  Use png_memset() after png_malloc() of big_row_buf when reading an
-    interlaced file, to avoid a possible UMR.
-  Undid recent revision of PNG_NO_STDIO version of png_write_flush().  Users
-    having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined.
-  Revised libpng*.txt documentation about use of png_write_flush().
-  Removed fflush() from pngtest.c.
-  Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h
-  Relocated misplaced PNG_1_0_X define in png.h that caused the prototype
-    for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE
-    builds.  This bug was introduced in libpng-1.2.15beta4.
-  Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt
-  Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles)
-  Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
-    application code writers to bypass the check for multiple inclusion
-    of setjmp.h when they know that it is safe to ignore the situation.
-  Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress
-    "shadowed declaration" warning from gcc-4.3.3.
-  Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
-    warning about a global "gamma" variable in math.h on some platforms.
+version 1.2.37beta02 [May 19, 2009]
+  Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG)
+  Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
+  Conditionally compile png_read_finish_row() which is not used by
+    progressive readers.
+  Added contrib/pngminim/preader to demonstrate building minimal progressive
+    decoder, based on contrib/gregbook with embedded libpng and zlib.

Glenn Randers-Pehrson	65a30ab0a2	Imported from libpng-1.2.37beta02.tar	2009-05-19 07:05:20 -05:00
Glenn Randers-Pehrson	61616abef2	Fixed cut-and-paste error in contrib/pngminim/preader/README "pngminus" should be "gregbook"	2009-05-18 15:19:29 -05:00
Glenn Randers-Pehrson	bb1fcd1ba8	Fixed a glitch in contrib/pngminim/preader/README.	2009-05-18 14:57:07 -05:00
Glenn Randers-Pehrson	6d65121993	Add contrib/pngminim/preader files (README, gather.sh, makefile.std, and pngusr.h)	2009-05-18 14:50:48 -05:00
Glenn Randers-Pehrson	ecf0bffb79	Added contrib/pngminim/preader demo of gregbook/rpng2-x with embedded libpng also minor editing of encoder/pngusr.h and decoder/pngusr.h	2009-05-18 14:46:35 -05:00
Glenn Randers-Pehrson	af2ea0a1f2	Revise ANNOUNCE to reflect conditional compile of png_read_finish_row().	2009-05-18 14:43:36 -05:00
Glenn Randers-Pehrson	286467db82	Restored compiling png_combine_row() for progressive readers. Only png_read_finish_row() can be omitted.	2009-05-18 13:40:23 -05:00
Glenn Randers-Pehrson	6b60a31ebf	Restore png_memset() call This stuff should be handled in the APNG fork.	2009-05-18 11:55:55 -05:00
Glenn Randers-Pehrson	54028e5943	Revert "png_reset_prev_row" from png.h and pngrutil.c This should be handled in the APNG fork, not in libpng proper.	2009-05-18 11:49:19 -05:00
Glenn Randers-Pehrson	0c062e839d	Conditionally compile png_combine_row() and png_read_finish_row() which are only used by sequential PNG readers. This can save some resources in applications that only do progressive reading.	2009-05-18 10:31:21 -05:00
