Warning when installing the 2.0.0-beta.8

[dev054]

Bug, feature request, or proposal:

What is the expected behavior?

What is the current behavior?

After ran npm i @angular/material@2.0.0-beta.8 -S it shows the warning:

npm WARN @angular/material@2.0.0-beta.8 requires a peer of @angular/cdk@2.0.0-beta.8 but none was installed.

I just read the CHANGELOG and it says:

@angular/material now depends on @angular/cdk as a peer dependency.

Does it means that from now we have to install @angular/cdk? If so, I think it should be more clear in CHANGELOG.

What are the steps to reproduce?

Install the latest version (2.0.0-beta.8).

Providing a Plunker (or similar) is the best way to get the team to see your issue.

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Material@2.0.0-beta.8

Is there anything else we should know?

Yes, you will need to install @angular/cdk as well

I think the problem here is that beta.8 was already released before today, and today the version was overridden, which, in my case, caused my CI build to fail.
Was this intentional?

@HarelM, this was my issue as well. I had a clean build yesterday with beta.8 and then today it failed with unmet peer dependency. Lots of confusion around this release change.

Ope yup, ^2.0.0-beta.x npm version got me confused.

[HarelM]

Sorry, my bad, I'm using ^2.0.0-beta.6 in my packages.json which caused my CI to take version 8 instead of 6.

I think

@angular/material now depends on @angular/cdk as a peer dependency.

Is pretty explicit. The getting-started guide has been updated as well, you can always check that out for installation instructions.

Version-management-wise, this is a breaking change.
npm can ignore the last digit assuming publisher will change the last digit only when not making breaking changes.
This is the global convention regarding versions numbering and this was a breaking change and the only digit that was changed was the last which is the problem, IMHO.
Since this is still in beta I'm not sure it should follow these rules but you should be aware of it nevertheless...

results in (SystemJS) XHR error (404 Not Found) loading ...... due to version numbering issue.

npm WARN @angular/material@2.0.0-beta.8 requires a peer of @angular/cdk@2.0.0-beta.8 but none was installed.
