Full Changelog: 2.4.1...2.5.0

tslib 2.4.1

This release contains fixes for early returns and throws invoked on generators.

tslib 2.4.0

This release includes the __classPrivateFieldIn helper as well as an update to __createBinding to reduce indirection between multiple re-exports.

tslib 2.3.1

This release updates the __spreadArray helper for TypeScript 4.4 to correctly operate on collections that are not "concat-spreadable" such as the DOM's NodeLists and HTMLCollections.

tslib 2.3.0

This release updates tslib to use TypeScript 4.4's upcoming __spreadArray helper which correctly preserves sparse array inputs (e.g. arrays containing "missing" elements like [1, 2, , 4]). This new version of __spreadArray is backwards-compatible and is often also faster. See #151 for more details.

tslib 2.2.0

This release supports TypeScript 4.3's new functionality for ECMAScript private methods and accessors, and private static class members.

It does so by expanding the scope of __classPrivateFieldGet and __classPrivateFieldSet. See #146 for more details.

tslib 2.1.0

This release adds a new __spreadArray helper which avoids side-effects compared to the now-deprecated __spreadArrays and __spread helpers. See #133 for more details.

This release also provides a more-specific error message when extending from a type which is not a function and not null. See #138 for more details.
