Check out the major new features in this release:

Project view performance

As a result of fixing MPS-38299 and MPS-37938, navigation in the logical project view has been substantially improved.

Optionally create languages without a generator

The New Project wizard now allows users to create a language without an empty generator. This covers the cases where a generator will not be needed in the project and prevents users from needing to manually delete the generator.

Enhanced transactional property cell

The CellModel_TransactionalProperty editor cell now supports the same properties as ordinary CellModel_Property cells, like readOnly and empty text, which encourages broader usage of the transactional property cell.

Build language as generation target

Based on a request from one of our customers, we smoothed the build language so that it can now be used as a target for generation. This opens the possibility for anyone to extend the build language in MPS or to create alternatives. A simple test language has been provided as an example to provide guidelines.

Numerous bug fixes
