# v4.3.22
|
|
|
|
## Enhancements
|
|
|
|
- Support to use placeholders like `${var}` in the HTTP `Headers` of rule-engine's Webhook actions [#9239](https://github.com/emqx/emqx/pull/9239).
|
|
|
|
- Asynchronously refresh the resources and rules during emqx boot-up [#9199](https://github.com/emqx/emqx/pull/9199).
|
|
This is to avoid slowing down the boot if some resources spend long time establishing the connection.
|
|
|
|
- Add a warning log if the ACL check failed for subscription [#9124](https://github.com/emqx/emqx/pull/9124).
|
|
This is to make the ACL deny logging for subscription behave the same as for publish.
|
|
|
|
- JWT ACL claim supports `all` action to imply the rules applie to both `pub` and `sub` [#9044](https://github.com/emqx/emqx/pull/9044).
|
|
|
|
## Bug fixes
|
|
|
|
- Fix that after uploading a backup file with an UTF8 filename, HTTP API `GET /data/export` fails with status code 500 [#9224](https://github.com/emqx/emqx/pull/9224).
|
|
|
|
- Improve the display of rule's 'Maximum Speed' counter to only reserve 2 decimal places [#9185](https://github.com/emqx/emqx/pull/9185).
|
|
This is to avoid displaying floats like `0.30000000000000004` on the dashboard.
|
|
|
|
- Fix the issue that emqx prints too many error logs when connecting to mongodb but auth failed [#9184](https://github.com/emqx/emqx/pull/9184).
|
|
|
|
- Fix that after receiving publish in `idle mode` the emqx-sn gateway may panic [#9024](https://github.com/emqx/emqx/pull/9024).
|
|
|
|
- "Pause due to rate limit" log level demoted from warning to notice [#9134](https://github.com/emqx/emqx/pull/9134).
|
|
|
|
- Restore old `emqx_auth_jwt` module API, so the hook callback functions registered in older version will not be invalidated after hot-upgrade [#9144](https://github.com/emqx/emqx/pull/9144).
|
|
|
|
- Fixed the response status code for the `/status` endpoint [#9210](https://github.com/emqx/emqx/pull/9210).
|
|
Before the fix, it always returned `200` even if the EMQX application was not running. Now it returns `503` in that case.
|
|
|
|
- Fix message delivery related event encoding [#9226](https://github.com/emqx/emqx/pull/9226)
|
|
For rule-engine's input events like `$events/message_delivered`, and `$events/message_dropped`,
|
|
if the message was delivered to a shared-subscription, the encoding (to JSON) of the event will fail.
|
|
Affected versions: `v4.3.21`, `v4.4.10`, `e4.3.16` and `e4.4.10`.
