Why must we do a "1.0" release?

[wbhart]

We don't have to. But why not?

[thofma]

Version number "1.0" sounds so mature. I think we already did a great job, but we are still lacking basic functionality to do linear system solving. Even in the field case. Maybe this should be on the list?

[wbhart]

Sure, feel free to add whatever you want to the list.

[rfourquet]

Just in case you don't know about the functionality and in case you may like to use it, Github has a milestones feature which can ease managing issues/PR related to a specific release.

Thanks, I did know about it, but forgot in this case. Doesn't matter too much now.
