v0.3.0

We're happy to announce the 0.3.0 release.

Thank @ijskar to add new end-to-end predict-then-optimize methods: noise contrastive estimation and learning to rank. We add modules pyepo.func.NCE, pyepo.func.pointwiseLTR, pyepo.func.pairwiseLTR and pyepo.func.listwiseLTR. See details in our docs.

There are the corresponding papers Contrastive losses and solution caching for predict-and-optimize and Decision-focused learning: through the lens of learning to rank.
