The preview of the upcoming version 2.1.9 release of the ODK-X Android tools is now available for testing!

Please report any issues or problems [here](https://github.com/opendatakit/tool-suite-X/issues).

The v2.1.8 tools are backward compatible with v2.1.\* BUT not backward compatible with previous versions (v2.0.\*). The incompatibility is internal to the ODK-X tools, all external files such as XLSX forms, JavaScript/HTML, and server interfaces are unaffected. Most users should experience a smooth upgrade.
