v0.7.9

• Support for GHC 9.8.1

v0.7.8

• Try and outright solve substituted constraints, the same as is done with the unsubstituted constraint. Partially Fixes #65.
• Support for GHC-9.6.0.20230210

v0.7.7

• Solve unflattened wanteds instead of the wanteds passed to the plugin. Fixes #1901.
• Add support for GHC 9.4

v0.7.2

• Fixes #44 infinite loop due to boxed equality

v0.7.1

• Add support for GHC 8.10.1-alpha2
• Fixes #23: Can't figure out + commutes in some contexts on GHC 8.6.3
• Fixes #28: Using the solver seems to break GHC
• Fixes #34: inequality solver mishandles subtraction

v0.5.9

• GHC 8.4.1 support

v0.5.1

• Fixes bugs:
  • Cannot solve an equality for the second time in a definition group

v0.5

• Solve simple inequalities, i.e.:
  • a <= a + 1
  • 2a <= 3a
  • 1 <= a^b

v0.4.2

• Find more unifications:
  • (2*e ^ d) ~ (2*e*a*c) ==> [a*c := 2*e ^ (d-1)]
  • a^d * a^e ~ a^c ==> [c := d + e]
  • x+5 ~ y ==> [x := y - 5], but only when x+5 ~ y is a given constraint

v0.4.1

• Find more unifications:
  • F x y k z ~ F x y (k-1+1) z ==> [k := k], where F can be any type function
