I noticed that there are several versions of a V6 design for the Colorado Top Bar (which I will be making). The manual is for the 5.4 version.

At first glance it looks a bit puzzling which version I should be building. Could there be a stickie referencing the latest prefered design files and manual?

Simply put there can be many design iterations and fine tuning before the design is useful and standardised for "production" and it might be useful for casual or first time browsers to have simple links to the current best design, updated manual and example pictures.

I'd endorse this. I'm also planning to be milling a hive soon, but I have struggled to find my way around the different versions and the difference with the manual version.

I also would like to know which version would be best for production. More info about the 6.6 can be found in this post (http://community.opensourcebeehives.net/t/design-review-colorado-top-bar-v6-6/225) but I am not sure if that one is ready for milling
