-<p>Currently, MacVim binary releases are available in two versions: a normal version (macOS 10.13 or above), and a legacy version (macOS 10.9 or above). Starting next release (r183), the normal version will require macOS 11.0 (due to Xcode 26 requirements), and macOS 10.13-10.15 users will need to use the legacy version instead. This will mostly be a transparent change, and the updater will automatically update to the right version. The legacy version should be almost identical to said users as they are using older versions of macOS that can’t make use of newer OS features to begin with.</p>
