# 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](https://meta.discourse.org/t/ability-to-ignore-a-user/110254/8).
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:
```plaintext
curl -i -sS -X POST "http://127.0.0.1:3000/categories" \
-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.
### 2.3.0.beta4 and UX fixes
This release also includes a number of small bug and UX fixes from our 2.3.0.beta3 release. Sites on the beta and tests-passed branches are encouraged to update to resolve these issues, including:
- Missing translations when “en” set as fallbackLocale
- Do not display add/remove participants if you can’t actually do it
- Sanitize theme settings properly before injecting into stylesheets
- Bugs in safari where select-kit is not expanding on iOS
- Fix post notice on mobile
- Text content search warning if more than 50 results
