Group owners are regular users that can add or remove users to a group
The Admin UX allows admins to appoint group owners
The public group UX will display group owners first and unlock UI to
add and remove members
Group owners can only be appointed on non automatic groups
Group owners may not appoint another group owner
On sites that don't otherwise configure an avatar fallback, Discourse will
now tell the client to get its letter avatars from a location which nginx
proxies to the centralised `avatars.discourse.org` service. This alleviates
privacy concerns, whilst still providing some degree of performance benefit
(no need for every site to delay avatar response by 300ms for image
rendering).
It is still possible to gain the benefits of global image caching and the
lower latency of requesting directly from a CDN, by explicitly changing the
`external_system_avatars_url` site setting to
`https://avatars.discourse.org/letter/{first_letter}/{color}/{size}.png`.
We cap new and unread at 2/5th of SiteSetting.max_tracked_new_unread
This dynamic capping is applied under 2 conditions:
1. New capping is applied once every 15 minutes in the periodical job, this effectively ensures that usually even super active sites are capped at 200 new items
2. Unread capping is applied if a user hits max_tracked_new_unread,
meaning if new + unread == 500, we defer a job that runs within 15 minutes that will cap user at 200 unread
This logic ensures that at worst case a user gets "bad" numbers for 15 minutes and then the system goes ahead and fixes itself up
- new hidden site setting 'migrate_to_new_scheme' (defaults to false)
- new rake tasks to toggle migration to new scheme
- FIX: migrate_to_new_scheme also works with CDN
- PERF: improve perf of the DbHelper.remap method
- REFACTOR: UrlHelper is now a class
Also changes behaviour of real to not return anonymous users.
This means user counts will no longer include them, and the
mailing list system will ignore them even if they somehow end up
with the feature turned on.
- add User.staff scope
- inject MessageBus into Ember views (so it can be used by the poll plugin)
- REFACTOR: use more accurate is_first_post? method instead of post_number == 1
- FEATURE: add support for JSON-typed custom fields
- FEATURE: allow plugins to add validation
- FEATURE: add post_custom_fields to PostSerializer
- FEATURE: allow plugins to whitelist post_custom_fields
- FIX: don't bump when post did not save successfully
- FEATURE: polls are supported in any post
- FEATURE: allow for multiple polls in the same post
- FEATURE: multiple choice polls
- FEATURE: rating polls
- FEATURE: new dialect allowing users to preview polls in the composer
