End of Service Life Policy

We encourage TestCast users always to use newest version of the tool and expect that it will be taken into use within 2 years after its first release date.

End of service life (EoSL) of the TestCast current version is reached 2 years after release date of the new version.

In case of active support and maintenance contract we provide patches for the older TestCast versions until EoSL is reached.

Currently we provide support for following TestCast versions: 6.19.1, 6.20.1 and 6.21.1.
