Modules released as part of the official MRST releases have now been given a classification based on the type of development they are currently undergoing. This is to help users determine how likely the code is to change in future releases. The main benefit of this is that users can be confident that their own code based on e.g. stable modules is unlikely to need updating much between releases whereas code based on experimental modules is much more likely to need updating to be compatible with future versions of these modules.

More information about individual modules can be found here and in the code for the modules themselves within MRST.

The categories are as follows:

Legacy

Mature code, stable, bug-fix mode only, not under active development.

Stable

Feature complete, well tested, changes are thoroughly documented and subject to strict testing.

Development

Under active development, internal interfaces / algorithms may change without notice, major interface changes documented.

Experimental

Recently added functionality, may change significantly between releases or disappear entirely if not sufficiently matured.

Deprecated

Has been / will be removed in future releases.
