Release Notes

sindresorhus/ora

### [`v4.0.3`](https://togithub.com/sindresorhus/ora/releases/v4.0.3) [Compare Source](https://togithub.com/sindresorhus/ora/compare/v4.0.2...v4.0.3) - Fix `discardStdin` option ([#​135](https://togithub.com/sindresorhus/ora/issues/135)) [`a4b2253`](https://togithub.com/sindresorhus/ora/commit/a4b2253) It's now also a noop on Windows as it turns out it's impossible to reliably discard stdin there without affecting other things. ### [`v4.0.2`](https://togithub.com/sindresorhus/ora/releases/v4.0.2) [Compare Source](https://togithub.com/sindresorhus/ora/compare/v4.0.1...v4.0.2) - Fix handling of Ctrl+C on spinners beyond first one ([#​131](https://togithub.com/sindresorhus/ora/issues/131)) [`17761e9`](https://togithub.com/sindresorhus/ora/commit/17761e9) ### [`v4.0.1`](https://togithub.com/sindresorhus/ora/releases/v4.0.1) [Compare Source](https://togithub.com/sindresorhus/ora/compare/v4.0.0...v4.0.1) - Set the correct interval when changing spinner by name ([#​128](https://togithub.com/sindresorhus/ora/issues/128)) [`4a8cd09`](https://togithub.com/sindresorhus/ora/commit/4a8cd09) ### [`v4.0.0`](https://togithub.com/sindresorhus/ora/releases/v4.0.0) [Compare Source](https://togithub.com/sindresorhus/ora/compare/v3.4.0...v4.0.0) ##### Breaking - Require Node.js 8 [`6459090`](https://togithub.com/sindresorhus/ora/commit/6459090) - Discard stdin by default ([#​112](https://togithub.com/sindresorhus/ora/issues/112)) [`b1f140b`](https://togithub.com/sindresorhus/ora/commit/b1f140b) This prevents the spinner from twitching on input, outputting broken lines on Enter key presses, and prevents buffering of input while the spinner is running. ##### Breaking for TypeScript users - Only use a CommonJS export for the TypeScript definition You need to change `import ora from 'ora';` to `import ora = require('ora');` ##### Fixes - Set the correct interval when changing spinner ([#​125](https://togithub.com/sindresorhus/ora/issues/125)) [`ad324dc`](https://togithub.com/sindresorhus/ora/commit/ad324dc) - Hide `prefixText` when it's an empty string ([#​124](https://togithub.com/sindresorhus/ora/issues/124)) [`8bcde17`](https://togithub.com/sindresorhus/ora/commit/8bcde17) - Fix Typescript definition for the `frame` method ([#​126](https://togithub.com/sindresorhus/ora/issues/126)) [`b653b5a`](https://togithub.com/sindresorhus/ora/commit/b653b5a)
