Release Notes - **Release date: April 1st, 2021** ### Fixes * We fixed a performance regression in loop execution. (Ticket 118288) We fixed the **list subtraction** operation, which now maintains the order of items. (Ticket 117625) * We improved the validity of sessions in session caches. As a result, changes made on one cluster node will now eventually be reflected on others. Also, `Core.getSessionById` will update the current session and related data in the current cluster node's session cache if the session validation timeout is passed. (Ticket 113448) * We fixed an issue with the document template when a conditionally visible row was always rendered if the enclosing data view had an empty object. (Ticket 115502) * We fixed an issue where revisions that were already merged were not shown as unavailable when doing a subsequent advanced merge from the same branch. (Ticket 117916) * We fixed an issue where you got an incorrect success message when uploading your app to a version control server failed. * We fixed an issue that resulted in non-unique document names when copying a document and pasting it in the same module.
