# v5.0.12
|
|
|
|
This version included a refactoring of MQTT bridge config.
|
|
The older version config file created from v5.0.11 or earlier will be converted to
|
|
according to the new schema.
|
|
|
|
Please note, the request body of `/bridges` API to configure MQTT brdige is changed in a incompatible way.
|
|
|
|
## Enhancements
|
|
|
|
- Disable global garbage collection by `node.global_gc_interval = disabled` [#9418](https://github.com/emqx/emqx/pull/9418)。
|
|
|
|
- Improve the CLI to avoid waste atom table when typing erros [#9416](https://github.com/emqx/emqx/pull/9416).
|
|
|
|
- Start building MacOS packages for Apple Silicon hadrdware [#9423](https://github.com/emqx/emqx/pull/9423).
|
|
|
|
- Remove support for setting shared subscriptions using the non-standard `$queue` feature [#9412](https://github.com/emqx/emqx/pull/9412).
|
|
Shared subscriptions are now part of the MQTT spec. Use `$share` instead.
|
|
|
|
- Refactor authn API by replacing `POST /authentication/{id}/move` with `PUT /authentication/{id}/position/{position}`. [#9419](https://github.com/emqx/emqx/pull/9419).
|
|
Same is done for `/listeners/{listener_id}/authentication/id/...`.
|
|
|
|
- Redesign `/rules` API to make `metrics` a dedicated resources rather than being included with every response [#9461](https://github.com/emqx/emqx/pull/9461).
|
|
|
|
- Add more PSK ciphers support [#9505](https://github.com/emqx/emqx/pull/9505).
|
|
|
|
- Improve `emqx_retainer` write performance: get rid of transactions on write [#9372](https://github.com/emqx/emqx/pull/9372).
|
|
|
|
- HTTP client library `ehttpc` upgraded from `0.4.0` to `0.4.2` [#9520](https://github.com/emqx/emqx/pull/9520).
|
|
|
|
- Add `handshake_timeout` option to MQTT SSL listener [#9502](https://github.com/emqx/emqx/pull/9502).
|
|
|
|
- Upgrade dashboard to [v1.1.3](https://github.com/emqx/emqx-dashboard-web-new/releases/tag/v1.1.3).
|
|
|
|
- Users can define the `externalTrafficPolicy` of service in EMQX Helm Chart [#9527](https://github.com/emqx/emqx/pull/9527).
|
|
|
|
- Return `204` instead of `200` for `POST /gateway/lwm2m/clients/{clientid}/{read,write,observe}` [#9480](https://github.com/emqx/emqx/pull/9480).
|
|
|
|
- Make possible to create an authentication entirely from environment variable [#9547](https://github.com/emqx/emqx/pull/9547).
|
|
As an example, one can now enable MySQL auth with:
|
|
`env EMQX_AUTHENTICATION__1='{mechanism="password_based",backend="mysql",server="localhost:3306",database="emqx",username="emqx",password="******",query="SELECT password_hash,salt FROM mqtt_user WHERE username=${username} LIMIT 1",enable=true}'`.
|
|
Prior to this change, overrides only work on top of existing authentication, for example, if there is already MySQL auth configured in `emqx.conf`
|
|
but we want to disable it, we can do it with `env EMQX_AUTHENTICATION__1__ENABLE=false`.
|
|
|
|
- Start building packages for Amazon Linux 2 [#9537](https://github.com/emqx/emqx/pull/9537).
|
|
|
|
## Bug fixes
|

|
|

|
|
|

|
|
|
|
- Fix some potential MQTT packet parse errors [#9477](https://github.com/emqx/emqx/pull/9477).
