It’s now consered as a legacy branch like RELENG_2_2 and RELENG_3. Future commits to RELENG_4 no longer needs re@’s approval, but only those committed to RELENG_4_11 (with re@’s approval, of course) will go to 4.11-RELEASE. 4.11-RELEASE will be the final 4-STABLE release and it will be a errata release.
