Draft comms for v4.0.0 release

[vanitabarrett]

What

Tell users about release of Frontend v4.0.0. This is a breaking release, so we need to be careful how we communicate these changes to users.

Why

So users know what changes have been released and where to look to find out what they might need to do.

How

On Design System homepage:

• update 'What's new' panel of Design System homepage

On Github:

• backlog comments

On Slack, post message on:

• #gov-uk-design-system on GDS
• #frontend on GDS
• #gov-uk-design-system on x-gov
• #design on x-gov

On email, send to list:

• Mailchimp

Who needs to know about this

Content Design

Done when

• Include acknowledgment of any contributors
• Message drafted
• 2i'd by team
• Posted when we've done the release

Have added draft announcement to page 6 of the 4.0 release comms doc. @calvin-lau-sig7 Can I get a review? :)

[EoinShaughnessy]

@vanitabarrett @calvin-lau-sig7 I've also added a draft update for the 'Whats new' panel into the 4.0 release comms doc. Let me know how that looks, and when we're happy with it, I'll raise a PR that we can hold off merging till the right time. :)

Thanks @EoinShaughnessy , looks good! Do we need to draft an email in Mailchimp too?

[EoinShaughnessy]

@vanitabarrett Cheers for reviewing! Yep, we do - I haven't used Mailchimp before, but I can draft the email and then find out how.

@vanitabarrett @calvin-lau-sig7 Hi! Have drafted an email message - it's on page 7 of the release comms doc. Feedback welcome! :)

[calvin-lau-sig7]

All looks great @EoinShaughnessy, nice one!
I've been meaning to write up a guide for mailchimp, perhaps I can do that and show you next week?

@calvin-lau-sig7 Cheers for reviewing! Yeah, that'd be magic, thanks!
