Alert component used in the docs but not available with latest release

[thisismydesign]

I don't how to use the Alert component showcased here:

• https://material-ui.com/components/snackbars/#customized-snackbars
• https://github.com/mui-org/material-ui/blob/master/docs/src/pages/components/snackbars/CustomizedSnackbars.js#L4

The docs specify the dependency as "@material-ui/lab": "^4.0.0-alpha.18", but using the latest v4.8.2 release this component is not there.

Which would make sense as it was added a few days ago: #18702

But it perhaps shouldn't be shown in the documentation yet?

Closing in favor of root cause issue: #19099

You can use the "Show the source" button to view the source, or the "Copy the source" button to copy it.

The docs specify the dependency as "@material-ui/lab"

No, they don't (not until the next release).

It isn't.

But reading between the lines, I suspect you might be following the GitHub link? If so I agree it makes a certain amount of sense to link to the same version of the code there, but it does somewhat depend on your reason for viewing the code in GitHub, rather than viewing the published version of the demo code natively in the docs.

Yes (but I quite literally closed this issue and stated just that in the referenced one).

I'm sure you know best but your doc references a doc folder in your github which has incorrect information. We can argue about what counts as "in the documentation" but you can't argue away a bad user experience.

@mbrookes what's the advantage of linking the HEAD vs the tag of the release? I don't remember why we didn't link the tag.
