This release introduces support for Scala 2.13.0-RC1 and updates the Cats version to 2.0.0-M1. Cats 2.0.0-M1 brings several testing dependency updates for algebra-laws, which is not compatible with any previous version (and is unlikely to be compatible with the eventual 2.0.0 release), but this release of algebra-core is verified to be binary-compatible with 1.0.x.

This release includes two new type classes, DeMorgan and Logic, introduced in #224.

We are planning to release 2.0.0 once Cats 2.0.0 is available.
