v2.1.14

Fixed

• Email templates with an unclosed, crossed or misspelled section tag no longer truncate the message silently: unmatched tags stay as visible text, and check.php and smoketest warn about them.
• selfcheck reports a root-owned logs/ directory or access-audit.php without group/other write permission as an error instead of passing, because the web worker cannot append and management returns 503.
• Returning with “Back” to a form using hideOnSuccess shows the recovery actions immediately after a bfcache restore.
• Starting a new fill cancels only that form's pending redirect instead of calling window.stop(), so other forms' requests on the page continue.
• Diagnostics keep an inherited ignored SIGINT ignored; stale fixture cleanup works for installation paths containing [; leftover root-owned fixtures appear as a selfcheck warning; the SPA fallback message no longer blames a control fixture that was served correctly.
• The printed undo command quotes the backup path. The Windows upgrade launcher stays within the 8191-character cmd.exe limit.
• The sandbox subject preview resolves {{field_label}} variables such as {{plan_label}}.
