23The current version @value{VERSION} is an alpha-release of the upcoming
24new release version 2-0 (should be there at the beginning of
252000). Items labeled with "TBC" in this news file are features which
26still have to be implemented and/or documented.
28Although there are no known bugs, it is to be
29expected that the current version @value{VERSION} is not as stable as
30the 1.2 version(s), since major changes were done to the @sc{Singular}
31kernel. Therefore, it is important to us, that users try out this new
34Furthermore, the current version is generally not yet as fast as version
351.2. But this is going to change dramatically in the upcoming release
38Thank you very much for your support!
