Translation of "beta version" into Thai

A development status given to a program or application that contains most of the major features, but is not yet complete. Sometimes these versions are released only to a select group of people, or to the general public. The testers are usually expected to report any bugs they encounter or any changes they'd like to see before the final release. This is the second major stage of development following the alpha version, and comes before the release candidate. [..]
