  • (breaking change) Matrix was moved to a separate shard: https://github.com/Exilor/matrix
  • The syntax of a method argument with a default value and a type restriction is now def foo(arg : Type = default_value). Run crystal tool format to automatically upgrade exsiting code to this new syntax. The old def foo(arg = default_value : Type) syntax will be removed in a next release.
  • Special handling of case with a tuple literal. See #2258.
  • Keywords can now be used for variable declaration, so property end : Time works as expected.
  • Comparison of signed vs. unsigned integers now always give a correct result
  • Allow declaring instance variables in non-generic module types (module Moo; @x : Int32; end)
  • Allow initializing instance variables in non-generic module types (module Moo; @x = 1; end)
  • Spec: allow setting multiple output formatters (thanks @marceloboeira)
