 The current version @value{VERSION} is the first release of the new 
-release series version 2-0.
-It contains a lot of new internal improvements, rewrites, new procedures etc.
-
-Although there are no known bugs, it is to be
-expected that the current version @value{VERSION} has some bugs in the 
-code sections, since major changes were done to the @sc{Singular}
-kernel. Therefore, it is important to us, that users try out this new
-version.

-The current version is generally much faster as version
-1.2 - because of new, better algorithms and impproved

+release series version 2-0. Its is a major upgrade from both, the 1-2 and 
+1-3 release serieses.
+
+Singular version 2 is generally much faster than any previous 
+version of Singular, due to a rewrite of major parts of the Singular
+kernel (e.g., the kernel has a new memory manager and a new polynomial
+arithmetic) and due to new and better implemented algorithms (e.g., for
+comuting resolutions and determinants). 
+
+Besides theses internal changes, Singular version 2 offers many new
+features and functionlities (which were partly already incorporated in
+the 1-3 series). E.g., a native Windows distribution, an Emacs user
+interface, a new help system, 16  new libraries, etc. 
+
+All these changes are explained in more detail below.
+
+@heading Efficiency Improvements
+The following table shows some timings which compare the efficincy of
+Singular version 1-2-3 and Singular version 2. All times are in seconds
+and were obtained on an AMD Athlon with 700 MHz, 128 MB RAM, running
+Linux.
