Updates between major versions of COYO (version 9, version 10, version 14 etc.) cannot be skipped. This means that a jump that bypasses a major version cannot be performed. Therefore, when updating from e.g. version 9.0.8 to version 14.11.0, please update to the latest Major 10 version (10.0.38) before you update to the latest Major 14 version. The main reason for this is database migrations, which are necessary for certain versions. You can find detailed instructions for updates in this article.
