+* 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 Specialized Modes and Packages in Emacs 23.4
+
+** EDE
+
+*** New variable `ede-project-directories'.
+EDE now refuses to automatically load a project file (Project.ede)
+unless the file is in one of the directories specified by this
+variable. This reduces the risk of inadvertently loading malicious
+project files. The commands `M-x ede-new' and `M-x ede' now offer to
+save directories to `ede-project-directories'.
+
+* 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., visiting several
+large (> 256MB) files in the same session.
