This file compiles the list of functional changes for each version. For backward-incompatible API changes, see UPGRADING.md.

2.0.0

  • The final expression does not use a non-capturing group for its first set of alternations. The s9e\RegexpBuilder\Builder::$standalone property can be used to control this behaviour.

    • Old: `(?:aa|bb(?:cc|dd))
    • New: aa|bb(?:cc|dd)

  • The Java output uses \uHHHH instead of \u{HHHH}.

  • Expressions created from meta-characters are moved to the end of a group.

    • Old: (?:.*|x)
    • New: (?:x|.*)

  • Strings are sorted after surrogate pairs are created.

    • Old: \uD83C\uDD90(?:\uFE0F|\uD83C[\uDFFB-\uDFFF])?
    • New: \uD83C\uDD90(?:\uD83C[\uDFFB-\uDFFF]|\uFE0F)?
