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.
Example of verifying integrity of tar.gz package of current release:
wget --content-disposition https://get.typo3.org/8.7.27/tar.gz wget --content-disposition https://get.typo3.org/8.7.27/tar.gz.sig gpg --verify typo3_src-8.7.27.tar.gz.sig typo3_src-8.7.27.tar.gz
Some security fixes can be considered as breaking changes in order to apply strong security defaults. Please read the security bulletins carefully - manual adjustments concerning backward compatibility are described there as well.
Otherwise, 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.
