Changes since the last public release (1.2.29):

version 1.2.30 [August 15, 2008]

  Updated libpng.pc-configure.in and libpng-config.in per debian bug reports.
  Restored png_flush(png_ptr) at the end of png_write_end(), that was
    removed from libpng-1.0.9beta03.
  Merged some cosmetic whitespace changes from libpng-1.4.0beta19.
  Inline call of png_get_uint_32() in png_get_uint_31(), as in 1.4.0beta19.
  Added demo of decoding vpAg and sTER chunks to pngtest.c, from 1.4.0beta19.
  Changed PNGMAJ from 0 to 12 in makefile.darwin, which does not like 0.
  Added new private function png_read_chunk_header() from 1.4.0beta19.
  Merge reading of chunk length and chunk type into a single 8-byte read.
  Merge writing of chunk length and chunk type into a single 8-byte write.
  Moved local array "chunkdata" from pngrutil.c to the png_struct, so
    it will be freed by png_read_destroy() in case of a read error (Kurt
    Christensen).
  Change "purpose" and "buffer" to png_ptr->chunkdata to avoid memory leaking.
  Change "chunkdata" to "png_ptr->chunkdata" in png_decompress_chunk(),
    and remove chunkdata from parameter list.
  Put a call to png_check_chunk_name() in png_read_chunk_header().
  Removed two calls to png_check_chunk_name() occuring later in the process.
  Added a call to png_check_chunk_name() in pngpread.c
  Relocated a misplaced "#endif /* PNG_NO_WRITE_FILTER */" in pngwutil.c
  Changed "-Wall" to "-W -Wall" in the CFLAGS in all makefiles (Cosmin Truta)
  Declared png_ptr "volatile" in pngread.c and pngwrite.c to avoid warnings.
  Enclose "volatile" declarations in #ifdef PNG_SETJMP_SUPPORTED (Cosmin).
  Added code in pngset.c to quiet compiler warnings.
  Updated contrib/visupng/cexcept.h to version 2.0.1
