Release notes need to be revisited. The changelog is ok but the release notes are meant for marketing. So we should talk about how to configure it within configuration, are there any logos that appear, and whether there is a difference between onprem and saas.

[bmicklea]

To be clear:
@mshaposhnik:

• Will this be included in SaaS and On-Prem assemblies by default?
• Can it be turned on/off in configuration?
• Provide a screenshot of the new signup/login screen with the LinkedIn logo for oAuth

PM will take this information and update the release note section with it.

@bmicklea
1 - yes,
2 - yes it can be switched off like any other OAuth provider - by setting CODENVY_LINKEDIN_CLIENT_ID and CODENVY_LINKEDIN_CLIENT_ID into NULL.
3 -

This will need docs. Not sure if I like the look and it doesn't include the other oauth links. I would think round corners like the google oauth icon below and also its not the same size/height of other information on the row. WDYT @bmicklea .

Update: Sorry I didn't look at saas(customers) or onprem. Looks like @mshaposhnik image above.

You can merge

@mshaposhnik where are those variables found (and it looks like you listed the same one twice, are there two?)

I don't see them in the codenvy.env file.

[JamesDrummond]

Documentation updated.

[JamesDrummond]

@bmicklea Think @mshaposhnik meant CODENVY_LINKEDIN_SECRET for the second variable. I updated the description above a little while ago.

[bmicklea]

Thanks, I still don't see them in the codenvy.env file so where are they changed?

[bmicklea]

Thanks Sergii. I don't think we usually want people messing with the codenvy.pp so I'll skip that in the release notes. This should be on by default for Codenvy.io SaaS though.

@bmicklea You are looking at the wrong file on the link. The link https://github.com/codenvy/codenvy/pull/1791/files#diff-4e1211b38190902dee42a5833ea2efb5R466 highlights code for codenvy.env not codenvy.pp even though that is the filename you see at first when you first click the link. Line 466 of codenvy.env is highlighted.
