v4.1.0

New Features

• Added installable namespacing option (off by default) that moves named capture results to a groups object. This makes it easier to loop over named captures after executing a regex, and aligns with native named capture handling in ES2018. See #175.
• Added the Cased_Letter (LC) category to the Unicode Categories addon. See #220.

Improvements

• Upgraded Unicode data from version 9.0.0 to 10.0.0. See #221.
• The generated source for regexes is now a bit easier to read, with fewer (?:) separating tokens. See #196.

v4.0.0

Breaking Changes

• XRegExp is now published as ES5, rather than ES3. See #108.
• XRegExp.install('natives') was removed. See #207.

New Features

• XRegExp.tag was added to the build plugin for tagged template string construction. See #180.
• $<n> and $<name> can be used as alternative backreference syntax in replacement text. See #181.
