Today Strange Loop Games have released version 8.3 for Eco.
Check out the official changelog for additions, changes and fixes.
With this release, we've edited the prefixes for resources to display the current versions correctly. (8.2.X -> 8.3.X -> 9.X.X)
Mod Developers, keep in mind to update your prefixes using the Edit resource feature.
Why 9.X.X? 9.0 will most likely be the next version of Eco as stated in the recent changelog.
Update 9.0 is actively being worked on in parallel and the first non-public staging versions are soon to be released. Stay tuned for more news on that at a later date.
