The two points are linked: older gdtb files were zipfiles, and if we were offering old formats for compatibility we couldn't just disable the compression-level choice when gdtb was selected. That's now updated in git. * We don't offer the legacy gdtb options any more. * We disable the compression choice when gdtb is selected. * We put up a warning on a gdtb save, pointing out that such files can't be read by gretl < 2020b. I guess we can dispense with the warning at some point, but 2020a is not really ancient yet.
