I have been maintaining a Draw document for several years that contains text that must align properly to associated graphics on the page. It has survived through a number of LibreOffice releases until version 6 came out. When I first opened the document under version 6 in March of this year, the text to graphics alignment was wildly wrong. The only way I could find to fix the problem was to abandon the original document and start a new one which also meant that I had to lose much of the history in the original document.
The new version of the document which has been compatible with Draw in version 6 has been working acceptably until this past week when my LibreOffice was upgraded to version 6.06. Now the new version text alignment is wildly wrong, but when I open the original document saved in February 2018 under the version 5 Draw, it is now properly aligned again. However, the new version has 7 months of updates that would take many hours to reproduce in the original document.
What I would like to know is whether I should expect this to change again in another new release, and which version of the document is the right one to maintain.
