Hey @christianparpart , when to expect the new release? :)

Hey @christianparpart , when to expect the new release? :)

hi @denisgolius, if you want to try out tabs asap, you can build from master, otherwise it will take some time until we have some confidence that tabs are somewhat stable, and we want to add some customization into it as well before the next release.
At the moment we are not planning to create new release, so most likely later this year
