Version 0.12.0
2022-03-14

[Feature] If the installed version of troff is not detected as groff, a warning is displayed.
[Changed] On platforms which probably use a package manager (currently, Linux and BSDs), the "update check" checkbox is disabled and the related libraries are not referenced.
[Improved] When exiting groffstudio, the Save function from the "save" button is reused.
[Changed] Less capital letters.
