History
-------
Since the beginning of 2005, a partnership of three companies has been working
on building together a tool designed to perform uncertainty treatment and
reliability analysis.

- 2014: (1.3, 1.4) Kriging, native windows support
- 2015: (1.5, 1.6) Vectorial kriging, HMat support
- 2016: (1.7, 1.8) Karhunen-Loeve process decomposition, NLopt bindings
- 2017: (1.9, 1.10) Canonical format low-rank tensor approximation, field functions

Meetings
--------
Each year a users day event is planned at the beginning of the summer allowing users to
exchange on their use of the library and keep up with the new features.
User days have been organized annually at EDF Lab Saclay (France) in June.
