There is done daily hard work on a new 1.0 release: GitHub - nextcloud/cms_pico at cms_pico-1.0
That is also marked as NC17 comparible: cms_pico/appinfo/info.xml at cms_pico-1.0 · nextcloud/cms_pico · GitHub
Jep. I mean with the last major version beta releases, there were news with major changes published quite early, e.g.: Time for some testing: Beta 1 of Nextcloud 16 is here!
Not sure why there is still none for NC17. It is beta, so no claims and every beta user has to know that there can be still bugs and incompatibilities, reported or not. But indeed as it is beta (and not dev/nightly), I assume it is meant to be ready for public testing. And it should be in everyone’s interest that this beta phase is as productive as possible:
- Admin panel should show the correct info about which apps have compatible releases and which not, so users can check in the first place if they can even test the majority of the apps they use or not (yet).
- An overview news thread here, as of mentioned reasons, makes sense, right with the first beta that is pushed to update channel. This could be even linked from within the admin panel, as “
see what's new”.
Ransomware protection has been fixed (new release available) meanwhile btw
