 Changes since the last public release (1.6.22):
 
-Version 1.6.23beta01 [May 29, 2016]
   Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying).
   Fixed the progressive reader to handle empty first IDAT chunk properly
     (patch by Timothy Nikkel).  This bug was introduced in libpng-1.6.0 and
@@ -33,22 +31,15 @@
   Added tests in pngvalid.c to check zero-length IDAT chunks in various
     positions.  Fixed the sequential reader to handle these more robustly
     (John Bowler).
-
-Version 1.6.23rc01 [June 2, 2016]
   Corrected progressive read input buffer in pngvalid.c. The previous version
     the code invariably passed just one byte at a time to libpng.  The intent
     was to pass a random number of bytes in the range 0..511.
   Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch.
   Added missing ")" in pngerror.c (Matt Sarrett).
-
-Version 1.6.23rc02 [June 4, 2016]
   Fixed undefined behavior in png_push_save_buffer(). Do not call
     memcpy() with a null source, even if count is zero (Leon Scroggins III).
-
-Version 1.6.23 [June 7, 2016]
   Fixed bad link to RFC2083 in png.5 (Nikola Forro).
