The ShEx community group is happy to announce the release of ShEx 2.1.

The new ShEx release consists of three deliverables:
 * Shape Expressions Language 2.1 http://shex.io/shex-semantics-20191008/
 * Shape Expressions Primer 2.1 http://shex.io/shex-primer-20191009/
 * Shape Expressions Test Suite 2.1 https://github.com/shexSpec/shexTest/
including 1089 validation tests, 99 negative syntax tests, 14 negative
structure tests and 432 schema conversion tests between ShExC, ShExJ and

The test suite has an Implementation Report including 4 of the 5
implementations: http://shexspec.github.io/shexTest/reports/2.1/

ShEx 2.1 is backwards compatible with ShEx 2.0. The major changes include:
 * `START` clauses in imported schemas are now ignored instead of throwing
an error
 * Added IMPORT functionality (round-trips between ShExC, ShExJ and ShExR).
 * Added language support in value sets.
 * Updated definition of semantics to clarify recursion.
 * Added annotations and semantic actions to node constraints.
 * ShExC grammar allows ()s around simple TripleConstraints.
 * Added hundreds of tests of schema, validation and structure tests.
 * Multi-line comments (/* … */).

ShEx is running as a W3C community group and is open for everyone
interested in the language and the related technologies to join at

Best regards,
Dimitris Kontokostas, Andra Waagmeester on behalf of the ShEx W3C CG
