2.0.1 02 Jan 2019
Release notes
- Work around a rustdoc ICE (#24)
Open source →
2.0.0 27 Dec 2018
Release notes
- Breaking changes:
  - leapjoin now takes a tuple of leapers, and not a &mut slice:
    
    from_leapjoin(&input, &mut [&mut foo.extend_with(...), ..], ..) becomes from_leapjoin(&input, (foo.extend_with(...), ..), ..)
    
    if there is only one leaper, no tuple is needed
  - Relation::from now requires a vector, not an iterator; use Relation::from_iter instead
- Changed the API to permit using Relation and Variable more interchangeably, and added a number of operations to construct relations directly, like Relation::from_join
- Extended leapfrog triejoin with new operations (PrefixFilter and ValueFilter)
