Changelog for typelevel-rewrite-rules-1.0.0.1

1.0.0.1

Now supports ghc-8.10! Unfortunately, ghc-8.6 and ghc-8.8 are no longer supported.
Now using ghc's builtin iteration limit instead of a hardcoded internal limit. Since ghc's limit is much smaller than our internal limit was, you may need to add something like {-# OPTIONS_GHC -fconstraint-solver-iterations=100 #-} if ghc recommends you to do so.
Now making use of givens. That is, you can now call a function expecting (xs ~ rewritten-expr) given (xs ~ expr). Previously, you could only call a function expecting (xs ~ expr) given (xs ~ rewritten-expr).
Now supports instance constraints. That is, you can now call a function which requires an Eq (Vec rewritten-expr) given an Eq (Vec expr). Previously, we only supported equality constraints (expr ~ rewritten-expr).
Now works with type variables of kind Nat and Symbol.
The generated code now passes ghc's core-lint check.
Error messages involving rewritten constraints now include the relevant rewrite rules.
Bugfix: a spurious "the substitution forms a cycle" message was sometimes emitted even when the substitution rules did not form a cycle (see #15).
Bugfix: rewrite rules were sometimes not firing (see #21).
Bugfix: error messages were sometimes missing the error location (see #17).
