Discourse 2.3.0.beta4 Release Notes


(Jennifer Levitt Birdsall) #1

New features in 2.3.0.beta4

Account for ignored_users when merging two users

This is part of the Ability to ignore a user feature.
When we merge two users, we need to account for merging their list of ignored_users too.

Header based auth for API requests

Now you can also make authenticated API requests by passing the
api_key and api_username in the HTTP header instead of query params.

The new header values are: Api-key and Api-Username.

Here is an example in cURL:

curl -i -sS -X POST "" \
  -H "Content-Type: multipart/form-data;" \
  -H "Api-Key: $API_KEY" \
  -H "Api-Username: system" \
  -F "name=7c1c0ed93583cba7124b745d1bd56b32" \
  -F "color=49d9e9" \
  -F "text_color=f0fcfd"

Allow users to easily track/watch/mute topics via email

If you reply to an email with the word “mute” a topic will be muted
If you reply to an email with the word “track” a topic will be tracked
If you reply to an email with the word “watch” a topic will be watched

These ninja command can help advanced mailing list ex-users, saves a trip
to the website

There is also support for Api-User-Id and Api-User-External-Id
instead of specifying the username along with the key.

Special call-out for new / returning posters.

A banner message appears when a new or a user who hasn’t posted in 2 months posts to encourage those users to continue to post.
