New minor version

[cubismod]

Hello :wave: , is it possible that a new minor version could be released? We're looking to integrate https://github.com/prometheus-community/jiralert/pull/140 into our stack which was merged the same day as 1.3 but not included in that release unfortunately. Thank you!

Now would be a great time to create a 1.4 release...
