CHANGELOG

8.1

• Add support for null-safe array access syntax (foo?.[0])

  +$expressionLanguage->lint($expression, [], ExpressionLanguage::IGNORE_UNKNOWN_VARIABLES);

7.1

• Add support for PHP min and max functions
• Add Parser::IGNORE_UNKNOWN_VARIABLES and Parser::IGNORE_UNKNOWN_FUNCTIONS flags to control whether parsing and linting should check for unknown variables and functions.
• Deprecate passing null as the allowed variable names to ExpressionLanguage::lint() and Parser::lint(), pass the IGNORE_UNKNOWN_VARIABLES flag instead to ignore unknown variables during linting

7.0

• The in and not in operators now use strict comparison

6.3

• Add enum expression function
• Deprecate loose comparisons when using the "in" operator; normalize the array parameter so it only has the expected types or implement loose matching in your own expression function

6.2
