We used to use this all the time (old Redmine server), but it doesn't work anymore. Any plans for a 4.x update/version?

works fine on 3.3

  by Anton Titkov over 7 years ago

Great tool!!
Works perfect on redmine 3.3.1 (I have removed limitation of versions from init.rb)

  by Ricard Siliuk over 7 years ago

Great plugin, using in for a while now.
And someone should update it to work with Redmine 3.3. Changed init.rb to allow newest version, works without hiccups in test environment. Good work!

The Plug-In sounds really good. but there are no Windows installation instructions. Does someone have detailed instructions of how to install it ? Thank you!

A really helpful little plugin if you already work with plantUML diagrams anyway.
