-Changes since the last public release (1.2.35):
-
-version 1.2.36 [May 7, 2009]
-
-  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.

-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a

+version 1.2.37 [June 4, 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.
+  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.
+  In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
+    is only one makefile in those directories, and revised the README files
+    accordingly.
+  Reformated sources in libpng style (3-space indentation, comment format)
+  Added sections about the git repository and our coding style to the
+    documentation (merged from libpng-1.4.0beta62)
+  Added a section about using png_get_io_ptr() in configure scripts to detect
+    the presence of libpng.

    Y2K compliance in libpng:
    =========================
 
-      May 7, 2009
+      June 4, 2009
 
       Since the PNG Development group is an ad-hoc body, we can't make
       an official declaration.
 
       This is your unofficial assurance that libpng from version 0.71 and
-      upward through 1.2.36 are Y2K compliant.  It is my belief that earlier
+      upward through 1.2.37 are Y2K compliant.  It is my belief that earlier
       versions were also Y2K compliant.
 
       Libpng only has three year fields.  One is a 2-byte unsigned integer

 IX.  (Omitted)
-X. Y2K Compliance in libpng
 
-May 7, 2009
+X. Detecting libpng
+
+The png_get_io_ptr() function has been present since libpng-0.88, has never
+changed, and is unaffected by conditional compilation macros.  It is the
+best choice for use in configure scripts for detecting the presence of any
+libpng version since 0.88.
+
+XI. Source code repository
+
+Since about February 2009, version 1.2.34, libpng has been under "git" source
+control.  The git repository was built from old libpng-x.y.z.tar.gz files
+going back to version 0.70.  You can access the git repository (read only)
+at
+
+    git://libpng.git.sourceforge.net/gitroot/libpng
+
+or you can browse it via "gitweb" at
+
+    http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
+
+Patches can be sent to glennrp at users.sourceforge.net or to
+png-mng-implement at lists.sourceforge.net or you can upload them to
+the libpng bug tracker at
+
+    http://libpng.sourceforge.net
+
+XII. Coding style
+
+Our coding style is similar to the "Allman" style, with curly
+braces on separate lines:
+
+    if (condition)
+    {
+       action;
+    }
+
+    else if (another condition)
+    {
+       another action;
+    }
+
+The braces can be omitted from simple one-line actions:
+
+    if (condition)
+       return (0);
+
+We use 3-space indentation, except for continued statements which
+are usually indented the same as the first line of the statement
+plus four more spaces.
+
+Comments appear with the leading "/*" at the same indentation as
+the statement that follows the comment:
+
+    /* Single-line comment */
+    statement;
+
+    /* Multiple-line
+     * comment
+     */
+    statement;
+
+Very short comments can be placed at the end of the statement
+to which they pertain:
+
+    statement;    /* comment */
+
+We don't use C++ style ("//") comments. We have, however,
+used them in the past in some now-abandoned MMX assembler
+code.
+
+Functions and their curly brackets are not indented, and
+exported functions are marked with PNGAPI:
+
+ /* This is a public function that is visible to
+  * application programers. It does thus-and-so.
+  */
+ void PNGAPI
+ png_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for all exported functions appear in png.h.
+
+We mark all non-exported functions with "/* PRIVATE */"":
+
+ void /* PRIVATE */
+ png_non_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for non-exported functions can appear in
+pngpriv.h or in the file where the function is located.
+
+The names of all exported functions and variables begin
+with  "png_", and all publicly visible C preprocessor
+macros begin with "PNG_".
+
+We put a space after each comma and after each semicolon
+in "for" statments, and we put spaces before and after each
+C binary operator and after "for" or "while".  We don't
+put a space between a typecast and the expression being
+cast, nor do we put one between a function name and the
+left parenthesis that follows it:
+
+    for (i = 2; i > 0; --i)
+       x[i] = a(x) + (int)b;
+
+Other rules can be inferred by inspecting the libpng
+source.
+
+XIII. Y2K Compliance in libpng
+
+June 4, 2009
 
 Since the PNG Development group is an ad-hoc body, we can't make
 an official declaration.
 
 This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.2.36 are Y2K compliant.  It is my belief that earlier
+upward through 1.2.37 are Y2K compliant.  It is my belief that earlier
 versions were also Y2K compliant.
 
 Libpng only has three year fields.  One is a 2-byte unsigned integer that

 .SH IX.  (Omitted)
-.SH X. Y2K Compliance in libpng
 
-May 7, 2009
+.SH X. Detecting libpng
+
+The png_get_io_ptr() function has been present since libpng-0.88, has never
+changed, and is unaffected by conditional compilation macros.  It is the
+best choice for use in configure scripts for detecting the presence of any
+libpng version since 0.88.
+
+.SH XI. Source code repository
+
+Since about February 2009, version 1.2.34, libpng has been under "git" source
+control.  The git repository was built from old libpng-x.y.z.tar.gz files
+going back to version 0.70.  You can access the git repository (read only)
+at
+
+    git://libpng.git.sourceforge.net/gitroot/libpng
+
+or you can browse it via "gitweb" at
+
+    http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
+
+Patches can be sent to glennrp at users.sourceforge.net or to
+png-mng-implement at lists.sourceforge.net or you can upload them to
+the libpng bug tracker at
+
+    http://libpng.sourceforge.net
+
+.SH XII. Coding style
+
+Our coding style is similar to the "Allman" style, with curly
+braces on separate lines:
+
+    if (condition)
+    {
+       action;
+    }
+
+    else if (another condition)
+    {
+       another action;
+    }
+
+The braces can be omitted from simple one-line actions:
+
+    if (condition)
+       return (0);
+
+We use 3-space indentation, except for continued statements which
+are usually indented the same as the first line of the statement
+plus four more spaces.
+
+Comments appear with the leading "/*" at the same indentation as
+the statement that follows the comment:
+
+    /* Single-line comment */
+    statement;
+
+    /* Multiple-line
+     * comment
+     */
+    statement;
+
+Very short comments can be placed at the end of the statement
+to which they pertain:
+
+    statement;    /* comment */
+
+We don't use C++ style ("//") comments. We have, however,
+used them in the past in some now-abandoned MMX assembler
+code.
+
+Functions and their curly brackets are not indented, and
+exported functions are marked with PNGAPI:
+
+ /* This is a public function that is visible to
+  * application programers. It does thus-and-so.
+  */
+ void PNGAPI
+ png_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for all exported functions appear in png.h.
+
+We mark all non-exported functions with "/* PRIVATE */"":
+
+ void /* PRIVATE */
+ png_non_exported_function(png_ptr, png_info, foo)
+ {
+    body;
+ }
+
+The prototypes for non-exported functions can appear in
+pngpriv.h or in the file where the function is located.
+
+The names of all exported functions and variables begin
+with  "png_", and all publicly visible C preprocessor
+macros begin with "PNG_".
+
+We put a space after each comma and after each semicolon
+in "for" statments, and we put spaces before and after each
+C binary operator and after "for" or "while".  We don't
+put a space between a typecast and the expression being
+cast, nor do we put one between a function name and the
+left parenthesis that follows it:
+
+    for (i = 2; i > 0; --i)
+       x[i] = a(x) + (int)b;
+
+Other rules can be inferred by inspecting the libpng
+source.
+

-From Andreas Dilger e-mail to png-implement, 26 March 1998:
-
-  In most cases, the "simple transparency" should be done prior to doing
-  gray-to-RGB, or you will have to test 3x as many bytes to check if a
-  pixel is transparent.  You would also need to make sure that the
-  transparency information is upgraded to RGB.
-
-  To summarize, the current flow is:
-  - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
-                                  with background "in place" if transparent,
-                                  convert to RGB if necessary
-  - Gray + alpha -> composite with gray background and remove alpha bytes,
-                                  convert to RGB if necessary
-
-  To support RGB backgrounds for gray images we need:
-  - Gray + simple transparency -> convert to RGB + simple transparency, compare
-                                  3 or 6 bytes and composite with background
-                                  "in place" if transparent (3x compare/pixel
-                                  compared to doing composite with gray bkgrnd)
-  - Gray + alpha -> convert to RGB + alpha, composite with background and
-                                  remove alpha bytes (3x float operations/pixel
-                                  compared with composite on gray background)
-
-  Greg's change will do this.  The reason it wasn't done before is for
-  performance, as this increases the per-pixel operations.  If we would check
-  in advance if the background was gray or RGB, and position the gray-to-RGB
-  transform appropriately, then it would save a lot of work/time.
