+Version 0.13.0
+2024-01-11
+
+[Feature] Support for hdtbl.
+[Changed] Build extras and build preprocessors are now listed in a multi-select box.
+[Improved] If no error has occurred, the log file will contain a success message.
+[Improved] The default font looked gross on macOS. This should be better now.
+[Bugfix] Calling troff over the system default shell now, potentially finding more paths.
+[Improved] BuildDocument uses a simpler execution approach now.
+[Feature] macOS Cmd+X/C/V are supported now.
+[Feature] Added a loading window so you won't think groffstudio would procrastinate.
+
+-------------------------------
+
 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.

 ## Features
 
 * Written in Lazarus (Free Pascal).
   * Should be cross-platform (but Windows support is mediocre yet).
