===ACT-R 7.0: 2015-Present===
At the 2015 workshop, it was argued that software changes required an increment in the model numbering to ACT-R 7.0.  A major software change was removal of the requirement that chunks must be specified based on predefined chunk-types.  The chunk-type mechanism was not removed, but changed from being a required construct of the architecture to being an optional syntactic mechanism in the software.  This allowed for more flexibility in knowledge representation for modeling tasks that require learning novel information and extended the functionality provided through dynamic pattern matching now allowing models to create new "types" of chunks.  This also lead to a simplification of the syntax required for specifying the actions in a production because all the actions now have the same syntactic form.  The ACT-R software has also been subsequently updated to include a remote interface based on JSON RPC 1.0.  That interface was added to make it easier to build tasks for models and work with ACT-R from languages other than Lisp, and the tutorial included with the software has been updated to provide Python implementations for all of the example tasks performed by the tutorial models.
