+Changes since the last public release (1.5.18):

-Version 1.5.18beta01 [August 21, 2013]
-  Delay calling png_init_filter_functions() until a row with nonzero filter
-    is found.
-
-Version 1.5.18beta02 [December 26, 2013]
-  Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
-    to '"%s" m' to improve portability among compilers.
-  Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
-  Conditionally compile some unused functions reported by -Wall in
-    pngminim.
-  Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
-    in the tar distributions.
-
-Version 1.5.18beta03 [January 1, 2014]
-  Fixed 'unused' warnings and merged with libpng16 pngvalid.
-    Various warnings revealed by configurations added to the tested
-    configurations in libpng 1.6 need corresponding fixes in libpng 1.5.
-    This takes the libpng 1.6 pngvalid.c and adds it back to libpng 1.5,
-    however one write-only test is currently disabled because it does not
-    work; possibly because of failures to reset or initialize the deflate
-    stream correctly in write-only cases.
-  Merged libpng-1.7 changes and created a single pngvalid.c
-  Merged pngvalid and pngtest from libpng-1.5; made compressed chunks
-    after IDAT work with the progressive read code (this is a minor and
-    somewhat ugly fix-up; the proper fix is in 1.6).
-  The 'make all-am' command no longer builds $(check_PROGRAMS), leading
-    to a lack of checks on cross-builds such as ARM.  Makefile.am also
-    requires correct dependencies for the check programs on pnglibconf.h
-    otherwise parallel builds on fast machines can sometimes pick up the
-    system pnglibconf.h.
-  Rebuilt configure scripts with automake 1.14.1 and autoconf-2.69.
-  Require automake-1.13 and enable automake "subdirs" feature in autoconf.ac.
-  Allow unversioned links created on install to be disabled in configure.
-    In configure builds 'make install' changes/adds links like png.h
-    and libpng.a to point to the newly installed, versioned, files (e.g.
-    libpng17/png.h and libpng17.a). Three new configure options and some
-    rearrangement of Makefile.am allow creation of these links to be disabled.
-
-Version 1.5.18beta04 [January 10, 2014]
-  Removed potentially misleading warning from png_check_IHDR().
-
-Version 1.5.18beta05 [January 20, 2014]
-  Updated scripts/makefile.* to use CPPFLAGS (Cosmin)
-
-Version 1.5.18rc01 [January 28, 2014]
+Version 1.5.19beta01 [February 27, 2014]
+  Moved redefines of png_error(), png_warning(), png_chunk_error(),
+    and png_chunk_warning() from pngpriv.h to png.h to make them visible
+    to libpng-calling applications.
+  Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
