Dear TYPO3 Community,

today we've released TYPO3 13.4.17 LTS and 12.4.36 LTS, which are ready for you to download.

Both versions are maintenance releases only. Composer package roave/security-advisories reported conflicts when trying to upgrade TYPO3 packages - due to a security advisory for third-party package enshrined/svg-sanitize - more details are provided in TYPO3-PSA-2025-001 (https://typo3.org/security/advisory/typo3-psa-2025-001).
