[Mike Beckerle]

We are pleased to announce the release of Daffodil 2.0.0!

Downloads are available as zip, tar, and rpm at:


https://opensource.ncsa.illinois.edu/projects/artifacts.php?key=DFDL&version=2.0.0

Daffodil is the open source implementation of the Open Grid Forum's
Data Format Description Language (DFDL) specification.

  http://www.ogf.org/dfdl

Daffodil uses DFDL descriptions to parse data into an XML or JSON
infoset for ingestion and validation. Daffodil can also perform the
reverse, by serializing or "unparsing" an infoset back to the original
data format.

Daffodil 2.0.0 is a monumental milestone that denotes stability and
usability, and is ready for general availability. Major features that
make up this release include:

- Support for unparse with one-to-one feature parity with parse
- New API with native support for JDOM, w3c DOM, Scala XML, XML text, and
JSON
- Support for many non-byte size encodings
- Support for xs:choice direct dispatch
- Support for xs:boolean types
- Support for xs:ignoreCase="yes"
- Support for xs:union restrictions
- Many improvements to the DFDL expression language
- Numerous bug fixes and performance improvements
