psalm/CHANGELOG.md

Version 2.0.0 (2018-05-11)

• Uses PHP Parser 4 (and thus requires PHP 7)
• Issue type MoreSpecificImplementedReturnType has been renamed LessSpecificImplementedReturnType
• Issue type PossiblyUndefinedArrayOffset is triggered for possibly undefined array keys (previously bucketed into PossiblyUndefinedVariable)

  $foo = rand(0, 1) ? ['a' => 1, 'b' => 2] : ['a' => 3];
  echo $foo['b'];
  

• removed stopOnFirstError <psalm /> config attribute, which hasn't been used in ages
• removed UntypedParam issue type, which also hasn't been used (MissingParamType is the replacement)
