v5.0.0

Breaking Changes

• Enable the namespacing feature by default for alignment with ES2018 (moves named capture properties to the groups object of matches and to the last argument of replacement callbacks): slevithan/xregexp#316
• Handle ES2018 capture names (mostly this adds support for an extended set of Unicode characters, but it also prevents using a number as the first character in a capture name): slevithan/xregexp#247
• Remove support for Unicode blocks, for alignment with ES2018 (use Unicode scripts instead): slevithan/xregexp#225

Improvements

• Support optional 'Script=' prefix (from ES2018 syntax) for Unicode script tokens: slevithan/xregexp#225
• XRegExp.matchRecursive: Add delimiter and position info to error when unbalanced delimiters are found: slevithan/xregexp#293
• Avoid inserting unneeded (?:) into native regex source in more cases: https://github.com/slevithan/xregexp/commit/076f9501965d9ddc4f1cf7b7626c77993b396a01 and https://github.com/slevithan/xregexp/commit/d78a26216691c975acf5424f371db9763f307c7a
• Defer to native flag s in ES2018 environments: https://github.com/slevithan/xregexp/commit/98abea85ed0da1e1b40d9b26cc6a299c297b8eae

Bug Fixes

• XRegExp.exec: Preserve the groups object that comes from native ES2018 named capture: https://github.com/slevithan/xregexp/commit/c4a83e76fc3e1ab5a9053618267dff33edd1174e
• XRegExp.exec: Set the groups property to undefined if there are no named captures: slevithan/xregexp#320
• XRegExp.escape: Escape whitespace in a way that works with ES6 flag u: slevithan/xregexp#197
• XRegExp.replace: Throw when using native named capture and a numbered backreference one higher than the number of captures in the replacement text: slevithan/xregexp#317
• XRegExp.replace: Fix edge case issues with replacement text syntax: slevithan/xregexp#318

v4.4.1

• Add browser field to package.json to fix webpack: slevithan/xregexp#308

v4.4.0

• Upgrade to Unicode 13.0.0
• Add TypeScript definitions and tests #285 #286 #288
