Latest version and translations

Please note that per 1-5-2020, the latest version in English and traditional Chinese are V9.1. Previous versions are no longer supported, but some can still be downloaded.

The versions 8 and 9 are not compatible with earlier versions, due to some fundamental changes. But V9 is compatible with the versions 8, with small adaptations. The English edition of this version will be validated. There is a Mandarin, German, and Montenegrin translation of Version 9.0, and a Traditional Chinese and Turkish translation of Version 8.03. Versions in Russian, Indonesian and Ukrainian are under scruteny.

There is a Spanish and Croatian version version of the Classification V6.2. These versions are no longer supported by PCNE but have proven their worth in several projects.
