+Changes from 4.0.1 to 4.1
+-------------------------
+1. The three executables gawk, pgawk, and dgawk, have been merged into
+ one, named just gawk. As a result:
+ * The -R option is gone
+ * Use -D to run the debugger. An optional file argument is a
+ list of commands to run first.
+ * Use -o to do pretty-printing only.
+ * Use -p to do profiling.
+
+2. The new -l option is used for loading dynamic extensions.
+Changes from 4.0.0 to 4.0.1
+---------------------------
+
+1. The default handling of backslash in sub() and gsub() has been reverted to
+ the behavior of 3.1. It was silly to think I could break compatibility that
+ way, even for standards compliance.
+
+XXX. Lots of minor bugs fixed and portability clean-ups along the way. See
+ the ChangeLog for details.

Changes from 3.1.8 to 4.0.0
