Export as EPUB is only relevant in Writer, and gives an error in the other apps. The (expected) error message is: "Error when saving the document <document name>: Wrong parameter. The operation was started under an invalid parameter." At least to Draw the item was added with the following commit (previously it was Attach to Email), I haven't checked if there was a previous version in other apps, those already seem to have Export as EPUB in 6.2. https://cgit.freedesktop.org/libreoffice/core/commit/?id=51fd99367b517b9a7630f5c089d5fa22a7252472 Author: andreas kainz <kainz.a@gmail.com> AuthorDate: Wed May 29 01:01:19 2019 +0200 Commit: andreas_kainz <kainz.a@gmail.com> CommitDate: Wed May 29 07:13:34 2019 +0200 NB tabbed layout update in all apps
