+strongswan-5.6.3
+----------------
+
+- Fixes a vulnerability in the stroke plugin, which did not check the received
+  length before reading a message from the socket. Unless a group is configured,
+  root privileges are required to access that socket, so in the default
+  configuration this shouldn't be an issue.
+  This vulnerability has been registered as CVE-2018-5388.
+
+⁻ CRLs that are not yet valid are now ignored to avoid problems in scenarios
+  where expired certificates are removed from CRLs and the clock on the host
+  doing the revocation check is trailing behind that of the host issuing CRLs.
+
+- The issuer of fetched CRLs is now compared to the issuer of the checked
+  certificate.
+
+- CRL results other than revocation (e.g. a skipped check because the CRL
+  couldn't be fetched) are now stored also for intermediate CA certificates and
+  not only for end-entity certificates, so a strict CRL policy can be enforced
+  in such cases.
+
+- In compliance with RFC 4945, section 5.1.3.2, certificates used for IKE must
+  now either not contain a keyUsage extension (like the ones generated by pki)
+  or have at least one of the digitalSignature or nonReputiation bits set.
+
+- New options for vici/swanctl allow forcing the local termination of an IKE_SA.
+  This might be useful in situations where it's known the other end is not
+  reachable anymore or that it already removed the IKE_SA, so there is no point
+  in retransmitting a DELETE and waiting for a response (it's also possible to
+  wait for a certain amount of time, e.g. shorter than all retransmits, until
+  destroying the SA).
+
+- When removing routes, the kernel-netlink plugin now checks if it tracks other
+  routes for the same destination and replaces the installed route instead of
+  just removing it.  Same during installation, where existing routes previously
+  weren't replaced.  This should allow using traps with virtual IPs on Linux.
+
+- The dhcp plugin only sends the client identifier option if identity_lease is
+  enabled.  It also can send longer identities (up to 255 bytes instead of the
+  previous 64 bytes).  If a server address is configured, DHCP requests are now
+  sent from port 67 instead of 68.
+
+- Roam events are now completely ignored for IKEv1 SAs.
+
+- ChaCha20/Poly1305 is now correctly proposed without key length. For
+  compatibility with older releases the chacha20poly1305compat keyword may be
+  included in proposals to also propose the algorithm with a key length.
+
+- Configuration of hardware offload of IPsec SAs is now more flexible and allows
+  a new mode, which automatically uses it if the kernel and hardware support it.
+
+- SHA-2 based PRFs are supported in PKCS#8 files as generated by OpenSSL 1.1.
+
+- The pki --verify tool may load CA certificates and CRLs from directories.
+
+- Fixed an issue with DNS servers passed to NetworkManager in charon-nm.
