EST 1st Edition - release 1.0 (1999 - 2003)
All version from 1999-2003 have been numbered as version 1.0. The last one was capable of representation of concurrent systems with LTSs, parallel composition of LTSs, strong, observational and testing equivalence checking between LTSs and ACTLW model checking on LTSs.

The project EST 1st Edition is now marked as matured, because we are not planning to add new features (others than GUI improvements). However, there is still a lot of work to do, including writing documentation, cleaning up the code, adding new examples etc. Hence, the project is not closed, yet.
Modules from EST 1st Edition and EST 2nd Edition are not interchangeable, i.e. EST 2nd Edition release-2-0 is not an upgrade of EST 1st Edition release-1-x.
In October 2006, we created local SVN repository for EST 1st Edition project (last version in this repository was labeled as revision 23). In October 2014, we created SVN repository at Savannah. First version in new repository is labeled as revison 95. Notes from local repository have not been passed to new repository.
