RiftLauncher will be updated frequently to add new features, fix issues and add compatibility with the latest Vintage Story versions.
To make everything work as expected users will need the latest version so only that one will be 100% supported and will work as expected.
Issues with old versions will be discarded if they are solved on the latest version.
If you find a vulnerability, do not publish exploit details in a public issue. Use the repository's private security advisory channel when available. If it is unavailable, contact the team privately through the Stratum Discord server and ask for a private channel.
