Release Notes

vuejs/vue-cli (@​vue/cli-plugin-babel)

v4.5.19

Compare Source

IMPORTANT NOTE: IE 11 has reached End-of-Life. The default browserslist query no longer includes IE 11 as a target.
If your project still has to support IE 11, you MUST manually add IE 11 to the last line of the .browserslistrc file in the project (or browserslist field in package.json)

🐛 Bug Fix

• @vue/babel-preset-app
  • [c7fa1cf] fix: always transpile syntaxes introduced in ES2020 or later, so that optional chaining and nullish coalescing syntaxes won't cause errors in webpack 4 and ESLint 6.
• @vue/cli-plugin-typescript
  • [5b57792] fix: typechecking with Vue 2.7, fixes #​7213

v4.5.18

Compare Source

Fix compatibility with the upcoming Vue 2.7 (currently in alpha) and Vue Loader 15.10 (currently in beta).

In Vue 2.7, vue-template-compiler is no longer a required peer dependency. Rather, there's a new export under the main package as vue/compiler-sfc.
