+A commit message consists of a **header**, **body** and **footer**. The header has a **type**, **scope** and **subject**:
```
<type>(<scope>): <subject>
The subject contains a succinct description of the change:
-* use the imperative, present tense: "change" not "changed" nor "changes"
-* don't capitalize the first letter
-* no dot (.) at the end
+- use the imperative, present tense: "change" not "changed" nor "changes"
+- don't capitalize the first letter
+- no dot (.) at the end
### Body
Another aspect of it is that large scale stylistic changes result in massive diffs that touch multiple files, adding noise to the git history and makes tracing behavior changes across commits more cumbersome.

### Pull Request Checklist
- Vue core has two primary work branches: `main` and `minor`.
- Make sure it doesn't accidentally cause dev-only or compiler-only code branches to be included in the runtime build. Notable case is that some functions in @vue/shared are compiler-only and should not be used in runtime code, e.g. `isHTMLTag` and `isSVGTag`.
- Performance
+
- Be careful about code changes in "hot paths", in particular the Virtual DOM renderer (`runtime-core/src/renderer.ts`) and component instantiation code.
- Potential Breakage

- **`vue(.runtime).global(.prod).js`**:

- For direct use via `<script src="...">` in the browser. Exposes the `Vue` global.
- - Note that global builds are not [UMD](https://github.com/umdjs/umd) builds. They are built as [IIFEs](https://developer.mozilla.org/en-US/docs/Glossary/IIFE) and is only meant for direct use via `<script src="...">`.

- In-browser template compilation:
- **`vue.global.js`** is the "full" build that includes both the compiler and the runtime so it supports compiling templates on the fly.
- **`vue.runtime.global.js`** contains only the runtime and requires templates to be pre-compiled during a build step.
`esm-bundler` builds of Vue expose global feature flags that can be overwritten at compile time:
- `__VUE_OPTIONS_API__`
+
- Default: `true`
- Enable / disable Options API support
- `__VUE_PROD_DEVTOOLS__`
+
- Default: `false`
- Enable / disable devtools support in production
