Updates under consideration are listed on this Trello board: Unturned Roadmap
The cards on the board aren't ordered in any particular way. i.e., they do not dictate the order of updates.
Miscellaneous requests and tasks that pop up take priority over the roadmap, so it may go a while between progress updates. For example, work for curated maps often takes priority.
Several high-priority ideas that don't yet have a solid plan, like car physics improvements or a crafting revamp, aren't listed on the board.
