Commit 0619e565 fixes this issue

I don't think this RFE is implemented in full extend e.g.

Following are missing:

• admin should specify which milestones are active in project
• prevent to move tickets to inactive milestones
• show only active milestones in web interface, list of milestones will be shorter and user can choose easier which milestone use (instead of scrolling over 50 closed milestones to get the right one)

Implemented improvements are mostly on Roadmap page. But the unfriendly part is editing milestone in issue details or setting new milestone when adding new issue - these still display the full list.

• admin should specify which milestones are active in project

I believe this is in the code

• prevent to move tickets to inactive milestones

This is achieved by not showing the inactive milestones on the drop-down

show only active milestones in web interface, list of milestones will be shorter and user can choose easier which milestone use (instead of scrolling over 50 closed milestones to get the right one)

I'm pretty sure this is done, if it is indeed not, then it surely needs to be fixed.
