 Noteworthy changes in version 1.3.5 (unreleased)
 ------------------------------------------------
 
+    * The configure options --enable-rsa and --disable-rsa can now be
+      used to enable or disable RSA support.  This can be useful for
+      embedded use where space is tight.  --enable-minimal includes
+      --disable-rsa.

     Installation Problems
     ---------------------
     If you get unresolved externals "gettext" you should run configure
     again with the option "--with-included-gettext"; this is version
-    0.10.40 which is available at ftp.gnu.org.
+    0.12.1 which is available at ftp.gnu.org.
 
     If you have other compile problems, try the configure options
     "--with-included-zlib" or "--disable-nls" (See ABOUT-NLS) or
