Strata v0.14 released

We are pleased to announce the release of Strata 0.14. This is the seventh preview release of Strata, our next-generation market risk toolkit.

Strata 0.14 includes a major rework of the market data system and calculation API in preparation
for version 1.0 which is expected at the end of June. There have also been some package and project renames to better setup the project for the long term.

The full release notes are included in the Strata documentation. The code is available on GitHub at https://github.com/OpenGamma/Strata.
