Hi, Jackrabbit uses the fine mechanism of releasing unstable versions on 'x.y' version lines where 'y' is odd, and stable releases where 'y' is even.
This scheme is not super well-known in the Maven ecosystem, and I think there's a risk of people being on unstable versions without realizing it. Of course that's ultimately on them, but I wonder if it wouldn't be better to have only the stable releases on Maven Central, and have the unstable versions only on https://repository.apache.org - that way people might somewhat more consciously 'opt in' to also seeing the unstable releases? Kind regards, Arnout
