The big feature of this release is support of ed25519 keys which OpenSSH supports since version 6.5. As mentioned in "How to generate secure SSH keys", ED25519 is an EdDSA signature scheme using SHA-512 (SHA-2) and Curve25519 The main problem with EdDSA is that it requires at least OpenSSH 6.5 ( ssh -V ) or GnuPG 2.1 ( gpg --version ), and maybe your OS is not so updated, so if ED25519 keys are not possible your choice should be RSA with at least 4096 bits.
