### New alert notification channels |
||||||
|
|
||||||
|
This release adds **five** new alert notifications channels, all of them contributed by the community. |
||||||
|
|
||||||
|
* Hipchat |
||||||
|
* Telegram |
||||||
|
* LINE |
||||||
|
* Pushover |
||||||
|
* Threema |
||||||
|
|
||||||
|
### Templating |
||||||
|
|
||||||
|
We added two new global built in variables in grafana. `$__interval` and `$__interval_ms` are now reserved template names in grafana and can be used by any datasource. |
||||||
|
We might add more global built in variables in the future and if we do we will prefix them with `$__`. So please avoid using that in your template variables. |
||||||
|
|
||||||
|
### Dedupe alert notifications when running multiple servers |
||||||
|
|
||||||
|
In this release we will dedupe alert notificiations when you are running multiple servers. |
||||||
|
This makes it possible to run alerting on multiple servers and only get one notification. |
||||||
|
|
||||||
|
We currently solve this with sql transactions which puts some limitations for how many servers you can use to execute the same rules. |
||||||
|
3-5 servers should not be a problem but as always, it depends on how many alerts you have and how frequently they execute. |
||||||
|
|
||||||
|
Next up for a better HA situation is to add support for workload balancing between Grafana servers. |
||||||
|
|
||||||
|
### Alerting more info |
||||||
|
|
||||||
|
You can now see the reason why an alert triggered in the alert history. Its also easier to detect when an alert is set to `alerting` due to the `no_data` option. |
||||||
|
|
||||||
|
### Improved support for multi-org setup |
||||||
|
|
||||||
|
When loading dashboards we now set an query parameter called orgId. So we can detect from which org an user shared a dashboard. |
||||||
|
This makes it possible for users to share dashboards between orgs without changing org first. |
||||||
|
|
||||||
|
We aim to introduce [dashboard groups](https://github.com/grafana/grafana/issues/1611) sometime in the future which will introduce access control and user groups within one org. |
||||||
|
Making it possible to have users in multiple groups and have detailed access control. |
||||||
|
|
||||||
|
## Upgrade & Breaking changes |
||||||
|
|
||||||
|
If your using https in grafana we now force you to use tls 1.2 and the most secure ciphers. |
||||||
|
We think its better to be secure by default rather then making it configurable. |
||||||
|
If you want to run https with lower versions of tls we suggest you put a reserve proxy in front of grafana. |
||||||
|
|
||||||
|
If you have template variables name `$__interval` or `$__interval_ms` they will no longer work since these keywords |
||||||
|
are reserved as global built in variables. We might add more global built in variables in the future and if we do, we will prefix them with `$__`. So please avoid using that in your template variables. |
||||||
