The contribution presents the results of verification of previous and newest versions of the TeX Gyre fonts, shows examples of various testing techniques, overviews suggestions and bugs; many of them, reported earlier, have already been fixed in the recent releases. “Synoptic tables” have been produced to list a full glyph repertoire to check it for correctness of shapes, completeness, consistency between regular, bold, italic, and bold italic faces, etc. We will also discuss the status and the future of the Cyrillic and Greek parts.
