+* Installation Changes in Emacs 23.4
+
+** The MS-Windows build prefers libpng version 1.14 or later.
+Versions of libpng before 1.14 had security issues, so we now
+recommend to use version 1.14 or later.  Precompiled Windows binaries
+require version 1.14 or later.  See README.W32 and nt/INSTALL for
+details and pointers to URLs where the latest libpng can be
+downloaded.

+* Changes in Emacs 23.4 on non-free operating systems
+
+** The MS-Windows port can now use more than 500MB of heap.
+Depending on the available virtual memory, Emacs on Windows can now
+have up to 2GB of heap space.  This allows, e.g., to visit several
+large (> 256MB) files in the same session.
