Hey App vendors, thanks so much for your engagement and support in making your Apps compatible with read-only mode whilst we continue to develop it. With the 6.9 Beta shortly upon us, we have had to make the decision to bump the feature from this release as it is not quite production ready. The good news is that in the coming couple of weeks we expect to be completed from the Atlassian side and that will give you a little extra time to get your App compatible for when the feature is released in 6.10.
Keep an eye on the EAP updates as we have 1-2 more deliverables to make it a simpler for plug-ins to be compatible with read-only mode, whilst not breaking your backward compatibility with earlier Confluence versions.
Thanks again for you ongoing support.
Adam - Confluence PM
