TYPO3 LTS versions receive plannable release schedule for upcoming maintenance releases. A release schedule creates transparent and plannable times for TYPO3 site owners to know when to expect a next bugfix and maintenance release. As for the regular maintenance releases we have planned the following release schedule, which usually happens on a Tuesday.
Please note, that if an urgent issue pops up, we will release without prior notice if necessary.
