With the development release of eXist 2.2.RC1 eXist Solutions has updated its LTS (Long Term Support) edition of eXist to version 2.1.2. The LTS release is for those commercial customers running eXist in production and contains all critical bug fixes from 2.2.RC1, but without the new features, which still require more testing. 2.1.2 LTS is fully backwards compatible with 2.1 LTS.
