What changed in v2? Please document breaking changes

[barbalex]

• This is a v2.x issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

Expect to find either documented realeases or a changelog file.

Current Behavior

There seems to be no documentation on breaking changes.

Context

I just updated to v2 and get an error:

Module not found: Can't resolve '@material-ui/core/SvgIcon' in 'C:\Users\alexa\node_modules\@material-ui\icons\utils'

So I need to revert to 1.1.0.

Seems weird that the icon is missed from the parent folder though: My project is situated at C:\Users\alexa\node_modules\apf2

What changed in v2?

@barbalex We have updated the icons to reflect what's available on https://material.io/tools/icons/. There are 5,000 icons. It's the best we can do. Some icons are no longer present, some icons have a different name, some new icons are available.

Please provide a full reproduction test case. This would help a lot 👷 .
A live example would be perfect. This codesandbox.io template may be a good starting point. Thank you!

After many iterations, we are happy to announce @material-ui/icons v2.0.0 💃.
With this version, you can take advantage of all the icons recently released by Google:
https://material.io/tools/icons/. There are more than 5,000 icons.
(#12036, #12170, #12111, #12225)

I fear we can't really do better than that.

Module not found: Can't resolve '@material-ui/core/SvgIcon' in 'C:\Users\alexa\node_modules\@material-ui\icons\utils'

This looks like a caching issue.

[barbalex]

Actually it seems that basic functionality is breaking as the full error message is:

../node_modules/@material-ui/icons/utils/createSvgIcon.js
Module not found: Can't resolve '@material-ui/core/SvgIcon' in 'C:\Users\alexa\node_modules\@material-ui\icons\utils'

It does not seem to be a missing icon that creates this problem. Or am I missing something?

I tried using the codesandbox.io template but got a different error:

Could not fetch dependencies, please try again in a couple seconds: Could not fetch version for material-ui/icons@latest: ENOENT: no such file or directory, open '/var/task/material-ui/icons@latest/package.json'

See here: https://codesandbox.io/s/py39j89m67

Where is that helpful sentence you quoted? I searched for releases, a changelog file or a mention in the readme file before updating. But found nothing.

[barbalex]

I ran:

del yarn.lock
rmdir /s node_modules
yarn cache clean

... and still get the error.

I am on Windows 10.

Your example is working fine when you remove the icons v1.x dependency:

[barbalex]

Oops. You're right. Sorry for not noticing there was that dependency. Seems like I do something in my app that does not happen in the code sandbox example and that works with v1.1.0.
