As I understand it, Couch currently includes version 3.54 of CKEditor. Will newer versions of CKEditor be included in future Couch releases? If I were to replace Couch's CKEditor with the latest version, should I expect to encounter any problems?
You are right - Couch ships with CKEditor version 3.5.4.
3.5.4 was the final version in 3.5 series and then development moved on to 3.6.
It was reported that some very major changes (additions - not fixes, mind you) have been brought into effect with 3.6 and this made me reluctant to switch to the upgraded version for fear of breaking existing Couch functionality (CKEditor is fairly tight-coupled with Couch).
However, if you wish to try out the latter versions, I'd be glad to document the (very simple) changes made to the original CKEditor distribution to integrate it into Couch.
Do let me know. Thanks.
