|

|
|
We could use github webhooks to automatic notify for updates
|
||
|
|
when a new update is pushed to the repository
|
||
|
|
even when server is already started and running but this would expose
|
||
|
|
a route which dev may don't know about, so let it for now but if
|
||
|
|
they ask it then I should add an optional configuration field
|
||
|
|
to "live/realtime update" and implement the idea (which is already implemented in the iris-go server).

The old remote endpoint for version checker is still available on the server for backwards

compatibility with older clients, it will stay there for a long period of time.
