2.3.1

This is the last release of weeder compatible with GHC 9.0.

• Weeder now analyzes top-level pattern bindings. For example, with the following input:

  module Dep (a, b) where
  
  xxx :: Int
  xxx = 3
  
  a, b :: Int
  (a, b) = (xxx, 1)

  ... weeder will determine that both a and b depend on xxx. While this is an over-approximation, it prevents weeder from reporting false positives. For more information, see #92.

• Corrected a typo in --help (#96).

• Shorten the help text for --require-hs-files (#97).

• Allow algebraic-graphs-0.6 (#95).

• Allow Dhall 1.41 (#99).

• Allow optparse-applicative-0.17 (#100).
