There are two main versions of IVEF around, the first is IVEF 0.1.x which was the original exchange format which has been implemented by a number of parties and is in operational use.

The second version is the IALA definition as it was developed by the IVEF Working Group. They worked with the version designated with 0.2.x. With the completion of IALA recommendation V-145 for IVEF and the refactoring of the IVEF-SDK the happy 1.0.0 version was born.

With the release of 1.0.0 the 0.1.x and 0.2.x versions became obsolete. All the 1.0.x IVEF-SDK versions contain the 0.2.5 version of the XSD (see downloads).


The release notes show the versions of separate components and the version of the entire SDK as encapsulating item. Note that the definition was recoded. For the 0.1.x and 0.2.x versions the IVEF_DEF, IVEF_TOOLS and IVEF_LIB components had their own version number. Since version 1.0.0 the IVEF-SDK release contains the Definition, Tools and Libraries.


The next scheduled release is the next patch release in the 1.0.x series.  Continuous work is done for the 1.0.x versions. The release date is not yet planned.

For IVEF_DEF 0.1 no new functionality is planned, there are also no known issues with either the library or the tooling, which means there is no release schedules for the 0.1 version of the SDK.
