I think it should be useful to know what version of LVGL the configuration file corresponds to, maybe adding it at the top of the file below the @file doxygen tag?
Do you mean adding it into lv_conf_template.h?
Yes, sorry about that, something like this:
/** * @file lv_conf.h * Configuration file for LVGL v7.x.x */
Done here: https://github.com/lvgl/lvgl/commit/673c4936942e4ff149c7123045ec6395e4be6670
I also update the release script to automatically update it.
