With Scroll documents, now you can link to the latest approved version of a document with a stable url. You can do this in the following way - 


First, Generate the share url of your document which should look something like this -

https://foo-bar.atlassian.net/wiki/plugins/servlet/ac/k15t-scroll-document-versions-for-confluence/k15t-docs-document-viewer?content.id=1123456



Then, append 
#!/view/latestApprovedat the end of the url like so - 

https://foo-bar.atlassian.net/wiki/plugins/servlet/ac/k15t-scroll-document-versions-for-confluence/k15t-docs-document-viewer?content.id=1123456#!/view/latestApproved


In case you want to link to last saved version (irrespective of the document status), then simply append #!/view/latest at the end of the url instead of #!/view/latestApproved
