Releases: microsoft/tslib
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.

Minor release for TS 4.0
- Use Object.prototype.hasOwnProperty.call.
- Skip default when iterating exports in __importStar.
- Shorter parameter name in __exportStar.
tslib 2.0.0
This release changes __exportStar and __importStar to use __createBinding which is incompatible with versions of TypeScript older than 3.9 (i.e. 3.8 and below).
tslib 1.13.0
This release reverts breaking changes in tslib that were not compatible with versions of TypeScript prior to 3.9. The behavior slightly diverges from that of TypeScript 3.9, but generally is compatible with previous versions of TypeScript-authored code.
The new behavior of TypeScript 3.9 will be available in tslib 2.0.0.
