(rant) someone @ Proxmox should clean up the roadmap wiki page
The roadmap wiki page is not much of an actual roadmap at all. It's all over the place; it still shows items that have been done since v7.3, and it looks nothing like an enterprise product's roadmap page. No next minor/major milestones are named there; no list of what's planned for them is shown. 8.4? 9.0? Who knows.
Seriously, Proxmox is amazing for what it does. But for a product that's marketing itself as VMware alternative for the enterprise, that roadmap page is borderline embarrassing. And it's guaranteed to put off most enterprise CTOs looking for a VMware alternative today.
There's competition out there that's nowhere as good as Proxmox is today, yet they have far more professional looking roadmaps and websites. /rant
