+@appendixsec Things that should be in 4.0
+
+We plan to make @strong{MySQL} 4.0 a 'quick' release where we only add
+some new stuff to enable others to help us with developing new features
+into 4.1.  The @strong{MySQL} 4.0 version should only take us about a
+month to make after which we want to stabilize it and start working on
+4.1.  4.0 should have the following new features:
 
 @itemize @bullet
 @item
-Fail safe replication.
+New table definition file format (@code{.frm} files) This will enable us
+to not run out of bits when adding more table options.  One will still
+be able to use the old .frm file format with 4.0;  All new created tables
+will however use the new format.
+
+The new file format will enable us to add new column types, more options
+for keys and @code{FOREIGN KEYS}.
+@item
+@code{mysqld} as a library.  This will have the same interface as the
+standard MySQL client (with an extra function to just set up startup
+parameters) but will be faster (no TCP/IP or socket overhead), smaller
+and much easer to use from embedded products.
+
+One will be able to define at link time if one wants to use the
+client/server model or a stand-alone application just by defining which
+library to link with.
+
+The @code{mysqld} will support all standard @strong{MySQL} features and
+one can use it in a threaded client to run different queries in each
+thread.
+@item
+Online backup with very low performance penalty.  The online backup will
+make it easy to add a new replication slave without taking down the
+master.
+@item
+@code{DELETE FROM table_name} will return the number of deleted rows. For
+fast execution one should use @code{TRUNCATE table_name}.
+@item
+Multi table deletes (cascading deletes) and multi table updates.
 @item
-Optimize, test and document transactions safe tables (BDB tables)
+Better replication.
 @item
-Allow users to change startup options.
+More functions for full text search.
+@item
+Character set casts and syntax for handling multiple character sets.
+@item
+Allow users to change startup options without taking down the server.
+@item
+Help for all commands from the client.
+@item
+Secure connections (with SSL).
