Update README.md

After the beta release (v2.0.0b1) the text of the README.md file needed to be updated. The changes are introduced in this PR to reflect the current state of the MDANSE code better.

 ## Version information
 
-This is the development version of MDANSE. The main difference compared to the previous version is the transition from Python 2 to Python 3, and from wxWidgets to Qt. The previous version, formerly in the 'develop' branch, can now be found in the **legacy** branch.
+This is the 2.x branch of MDANSE, which consists of two Python packages, MDANSE (the analysis code) and MDANSE_GUI (the user interface). The final version in the 1.5.x series can still be found in the **legacy** branch, but is not being actively developed.
 
-The current version of MDANSE is currently still at the _alpha_ stage. You can help it advance to the _beta_ stage by reporting problems you experience while using MDANSE.

-Each of these analyses can be controlled using a number of parameters. For example, the user can select a subset of trajectory frames or a subset of atoms on which to perform the calculation, or specified atoms can be substituted with
