Hi All, 

Just updating you that v3.0.0 of NEMOSIS has been released. Recent updates include: data type parsing by default in the API, better functionality for building data caches, more instructive error messages, better API documentation (https://github.com/UNSW-CEEM/NEMOSIS/blob/master/README.md#using-the-python-interface-api) and a new set of API examples (https://github.com/UNSW-CEEM/NEMOSIS/tree/master/examples).

Cheers,

Nick
