DALI Release 0.31.0
The DALI 0.31 is not a major release, so the features, functionality, and performance might be limited.
Using DALI 0.31
To upgrade to DALI 0.31 from an older version of DALI, follow the installation and usage information in the DALI User Guide.
Note: The internal DALI C++ API used for operator’s implementation, and
the C++ API that enables using DALI as a library from native code, is
not yet officially supported. Hence these APIs may change in the next release
without advance notice.
