Package Signatures

TYPO3 Release Packages (the downloadable tarballs and zip files) as well as Git tags are signed using PGP signatures during the automated release process. Besides that, MD5 and SHA2-256 hashes are being generated for these files. Find more details on verifying signatures and hashes in the infrastructure guide.

Upgrading

The usual upgrading procedure applies. No database updates are necessary. It might be required to clear all caches; the "important actions" section in the TYPO3 Install Tool offers the accordant possibility to do so.
