 Changes since the last public release (1.5.0):
 
-version 1.5.1beta01 [January 8, 2011]
   Added description of png_set_crc_action() to the manual.
   Added a note in the manual that the type of the iCCP profile was changed
-    from png_charpp to png_bytepp in png_get_iCCP().  This change happened
-    in version 1.5.0beta36 but is not noted in the CHANGES.  Similarly,
+    from png_charpp to png_bytepp in png_get_iCCP().  Similarly,
     it was changed from png_charpp to png_const_bytepp in png_set_iCCP().
   Ensure that png_rgb_to_gray ignores palette mapped images, if libpng
     internally happens to call it with one.
   Fixed the failure to handle palette mapped images correctly.
-
-Version 1.5.1beta02 [January 14, 2011]
   Fixed a bug in handling of interlaced images (bero at arklinux.org).
   Updated CMakeLists.txt (Clifford Yapp)

-Version 1.5.1beta03 [January 14, 2011]
   Fixed typecasting of some png_debug() statements (Cosmin)
-
-Version 1.5.1beta04 [January 16, 2011]
   Updated documentation of png_set|get_tRNS() (Thomas Klausner).
   Mentioned in the documentation that applications must #include "zlib.h"
     if they need access to anything in zlib.h, and that a number of
     macros such as png_memset() are no longer accessible by applications.
   Corrected pngvalid gamma test "sample" function to access all of the color
     samples of each pixel, instead of sampling the red channel three times.
-  Prefixed variable names index, div, exp, gamma with "png_" to avoid "shadow"
-    warnings.
-
-Version 1.5.1beta05 [January 16, 2011]
-  Changed variable names png_index, png_div, png_exp, and png_gamma to
-    char_index, divisor, exp_b10, and gamma_val, respectively, and
-    changed exp() back to png_exp().
-
-Version 1.5.1beta06 [January 20, 2011]
+  Changed variable names index, div, exp, and gamma to char_index, divisor,
+    exp_b10, and gamma_val, respectively, to avoid "shadow" warnings.
   Prevent png_push_crc_skip() from hanging while reading an unknown chunk
     or an over-large compressed zTXt chunk with the progressive reader.
   Eliminated more GCC "shadow" warnings.
   Revised png_fixed() in png.c to avoid compiler warning about reaching the
     end without returning anything.
-
-Version 1.5.1beta07 [January 22, 2011]
   In the manual, describe the png_get_IHDR() arguments in the correct order.
   Added const_png_structp and const_png_infop types, and used them in
     prototypes for most png_get_*() functions.
-
-Version 1.5.1beta08 [January 23, 2011]
   Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name()
   Added synopses for the IO_STATE functions and other missing synopses
     to the manual. Removed the synopses from libpngpf.3 because they

     skipping of unread data (e.g. if the reader marks a chunk to be skipped.)

-Version 1.5.1beta11 [January 28, 2011]
-  Changed PNG_UNUSED from "param=param;" to "{if(param){}}".
-  Corrected local variable type in new API png_process_data_skip()
