Vircadia is always changing, as we work to improve performance and add features that will enhance your experience in the metaverse. If a new version has been released, all of our users will be prompted to update to the latest (and most stable) release.
Vircadia requires that the client and server (the visitor's installed software and the server's software) maintain protocol compatibility across versions. Some of our releases include protocol changes, and will affect the visitors who can visit your domain.
An updated client version will be unable to connect to a domain that is not updated.
A client running an older version will be unable to connect to a domain that is running a new version.
Both of these will result in an error message "Protocol Mismatch".
Because all of Vircadia's users are encouraged to update to the latest release, it is highly likely that the majority of your visitors are running the newest version of Vircadia. Therefore, if there has been a protocol change (check the Release Notes for your version), we strongly recommend that you upgrade your domain server to the newest release.
