More frequent releases

[weeco]

Could you create Docker builds more frequently? The last build is 3 months ago and since then there has been a couple of bugs fixed. I need these bugfixes and until you create a new release.

Thus I got to build the Dockerfile myself from Master which is not ideal because I don't know if master is kinda stable or not at the moment. More frequent builds which may just contain a couple bugfixes would certainly help.

@Jusshersmith let's prepare a release for end of March.
