Changes for version 5.90085 - 2015-03-25

  • Small change to Catalyst::Action to prevent autovivication of Args value (dim1++)
  • Minor typo fixes (Abraxxa++)
  • Make sure than when using chained actions and when more than one action matches the same path specification AND has Args(0), that we follow the "in a tie, the last action defined wins" rule. There is a small chance this is a breaking change for you. See Catalyst::Upgrading for more. You may use the application configuration setting "use_chained_args_0_special_case" to disable this new behavior, if you must for back-compat reasons.
  • Added PATCH HTTP Method action attribute shortcut.
  • Several new configuration options aimed to give improved backwards compatibility for when your URL query parameters or keywords have non UTF-8 encodings. See Catalyst::Upgrading.
