>We've just released Steam Audio 4.0.0, which is a major update to Steam Audio. This release includes new features and an updated API that is more flexible than previous releases. Because this is a major update, the version numbering we used so far was no longer sufficient: we have updated from 2.0-beta.20 (the previous release) to 4.0.0 (the next available integer).
