A beta build of Particle Fleet 1.1 is now available on the "beta" branch on steam. To access the beta build you need to right click Particle Fleet in the steam client and select "Properties". Then choose the "BETA" tab. From there is a drop down. Select "Beta" in the drop down. You may need to exit and restart the steam client to get the beta build.
Other than various bug fixes the main feature in 1.1 is ship sharing. There is now an "online" button next to "stock" and "custom". That will allow you to browse and download ships that have been uploaded. And of course you can now also upload ships from the ship browser.
There is a Ships forum where each uploaded ship gets a topic automatically created.
The version will read "1.1b4".
