Yes. We will announce here on the forums and in our Weekly Development Update Blog when the public test for SU10 is available to players. As with previous tests, we want to stress that this is not an “early access” build for people who want to try SU10 before its official release. The public test is specifically for people who wish to assist the dev team by testing the patch notes and confirming the things that were supposed to be fixed are actually fixed and searching for regressions (things that previously worked but are now broken).
