XM L 6.1.1 ( March 21, 2016)
Document saving is now a lot more robust. All failed save attempts will be retried automatically. In case of errors, authors will first see a warning near the save button. A warning dialog will appear if these errors persist. Authors can choose to continue anyway, but the warnings will reappear periodically until the error is resolved.
Failed requests are no longer ignored in specific cases. Any CMS request that does not get a response after 60 seconds is now considered to have failed.
Clicking the save button no longer skips documents that have already been auto-saved, it now sends explicit save requests (autosave=false) for all documents that have changed since the last manual save.
