## Changes from previous versions

The changes made from v.4.4 to 5.0 concern mostly the format of the input files:

- The main input file is written now in ``keyword - value'' manner, where the order of keywords in almost arbitrary.

- The molecular description files have now extension ``.mmol''. Most of old .mol files can be just renamed to .mmol

- A few parameters of the old input file (concerning, for example, treatment of 1-4 neighbors) are now moved into .mmol files.

There are also some changes in functionality, see the description below.
