(Darrel, I, Slavek, and Tim to a lesser extent were involved with the rebranding, graphics changes, etc.., Darrel did the lions share of reorganizing and rebranding the TDE help system and Slavek implemented most of the k->t name changes -- though if I recall correctly he was also mired in completing to move to CMake at the time) Functionally, v3.5.13 will likely lack a number of the improvements in the current version (for a while significant improvements were "cherry-picked" and backported to v3.5.13, but I don't know if that has been done in years) You will not be able to mix/match any of the current version TDE components with v3.5.13 components because of the internal k->t renaming that took place. Unless there have been other changes to v3.5.13 since 2014, that, in a nutshell, is the difference. -- David C. Rankin, J.D.,P.E.
