This commit allows admins to filter the list of feature
feed items on the "What's new?" page to _only_ show experiments.
This is useful to both find existing experiments they may have
enabled, and to get a better overview of new ones they would
like to try.
This will eventually not be required when we build a dedicated
config page for experiments.
Experimental "What's new?" feature feed items previously calculated
a boolean for experimentEnabled on the client based on the siteSettings
service, and this would control the initial state of the experiment
toggle.
However this requires the person who creates the site setting for the
experiment to remember to set it to `client: true`. This commit removes
that manual step by calculating whether the experiment is enabled
server-side, where we have access to all the site settings.
This version number is a technical detail that controls
what items show up on certain sites, most admins don't
need this level of detail. Remove it here, maybe we can
add it back in some hidden way later if needed.
This PR adds a small visual change to the new feature item on the `/admin/whats-new` page. When features are marked with an experimental site setting, they should show an indication on the feature item that it is "Experimental"
Toggle the button to enable the experimental site setting from "What's new" announcement.
The toggle button is displayed when:
- site setting exists and is boolean;
- potentially required plugin is enabled.
This commit adds a blue dot next to the "What's New"
link in the admin sidebar if the user has not seen the
new features yet, as a followup to 3e5976f8436255185de556ae165d9d849ac8fb3a
which removed the tab on the dashboard that had this same
functionality.
When the admin visits the "What's New" page they count
as having seen all the features straight away. This could
be something we want to change, but for now this keeps the
same functionality.
We used to show New Features in a tab on the dashboard,
but this could get pushed down the page especially on
our hosting. In 043117ca13
we made a separate What's New page, so this commit removes
the dashboard tab and changes the admin notification to
send the admin to /admin/whats-new instead of the dashboard
tab.
