   Changed remaining "key" to "png_ptr->chunkdata" in png_handle_tEXt()
     to avoid memory leak after memory failure while reading tEXt chunk.`
 
+version 1.2.33 [October 31, 2008]
+  No changes.
+
+version 1.2.34beta01 [November 27, 2008]
+  Revised png_warning() to write its message on standard output by default
+    when warning_fn is NULL. This was the behavior prior to libpng-1.2.9beta9.
+  Fixed string vs pointer-to-string error in png_check_keyword().
+  Added png_check_cHRM_fixed() in png.c and moved checking from pngget.c,
+    pngrutil.c, and pngwrite.c, and eliminated floating point cHRM checking.
+  Added check for zero-area RGB cHRM triangle in png_check_cHRM_fixed().
+  In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant
+    check for all-zero coordinates that is detected by the triangle check.
+  Revised png_warning() to write its message on standard output by default
+    when warning_fn is NULL.
+
+version 1.2.34beta02 [November 28, 2008]
+  Corrected off-by-one error in bKGD validity check in png_write_bKGD()
+    and in png_handle_bKGD().
+
+version 1.2.34beta03 [December 1, 2008]
+  Revised bKGD validity check to use >= x instead of > x + 1
+  Merged with png_debug from libpng-1.4.0 to remove newlines.
+
+version 1.2.34beta04 [December 2, 2008]
+  More merging with png_debug from libpng-1.4.0 to remove newlines.
+
+version 1.2.34beta05 [December 5, 2008]
+  Removed redundant check for key==NULL before calling png_check_keyword()
+    to ensure that new_key gets initialized and removed extra warning
+    (Arvan Pritchard).
+
+version 1.2.34beta06 [December 9, 2008]
+  In png_write_png(), respect the placement of the filler bytes in an earlier
+    call to png_set_filler() (Jim Barry).
+
+version 1.2.34beta07 [December 9, 2008]
+  Undid previous change and added PNG_TRANSFORM_STRIP_FILLER_BEFORE and
+    PNG_TRANSFORM_STRIP_FILLER_AFTER conditionals and deprecated
+    PNG_TRANSFORM_STRIP_FILLER (Jim Barry).

+  Zero out some arrays of pointers after png_malloc(). (Tavis Ormandy)
+
+version 1.2.35beta02 [Feburary 4, 2009]
+  Zero out more arrays of pointers after png_malloc().
+
+version 1.2.35beta03 [February 5, 2009]
+  Use png_memset() instead of a loop to intialize pointers.  We realize
+    this will not work on platforms where the NULL pointer is not all zeroes.
+

+  No changes.
+
+version 1.2.35rc02 [February 12, 2009]
