+strongswan-5.5.2
+----------------
+
+- Support of Diffie-Hellman group 31 using Curve25519 for IKE as defined
+ by RFC 8031.
+
+- Support of Ed25519 digital signature algorithm for IKEv2 as defined by
+ draft-ietf-ipsecme-eddsa. Ed25519-based public key pairs, X.509 certificates
+ and CRLs can be generated and printed by the pki tool.
+
+- In-place update of cached base and delta CRLs does no leave dozens
+ of stale copies in cache memory.
+
+
+strongswan-5.5.1
+----------------
+
+- The newhope plugin implements the post-quantum NewHope key exchange algorithm
+ proposed in their 2015 paper by Erdem Alkim, Léo Ducas, Thomas Pöppelmann and
+ Peter Schwabe.
+
+- The libstrongswan crypto factory now offers the registration of Extended
+ Output Functions (XOFs). Currently supported XOFs are SHAKE128 and SHAKE256
+ implemented by the sha3 plugin, ChaCHa20 implemented by the chapoly plugin
+ and the more traditional MGF1 Mask Generation Functions based on the SHA-1,
+ SHA-256 and SHA-512 hash algorithms implemented by the new mgf1 plugin.
+
+- The pki tool, with help of the pkcs1 or openssl plugins, can parse private
+ keys in any of the supported formats without having to know the exact type.
+ So instead of having to specify rsa or ecdsa explicitly the keyword priv may
+ be used to indicate a private key of any type. Similarly, swanctl can load
+ any type of private key from the swanctl/private directory.
+
+- The pki tool can handle RSASSA-PKCS1v1.5-with-SHA-3 signatures using the
+ sha3 and gmp plugins.
+
+- The VICI flush-certs command flushes certificates from the volatile
+ certificate cache. Optionally the type of the certificates to be
+ flushed (e.g. type = x509_crl) can be specified.
+
+- Setting cache_crls = yes in strongswan.conf the vici plugin saves regular,
+ base and delta CRLs to disk.
+
+- IKE fragmentation is now enabled by default with the default fragment size
+ set to 1280 bytes for both IP address families.
+
+- libtpmtss: In the TSS2 API the function TeardownSocketTcti() was replaced by
+ tss2_tcti_finalize().
+
+
+strongswan-5.5.0
+----------------
+
+- The new libtpmtss library offers support for both TPM 1.2 and TPM 2.0
+ Trusted Platform Modules. This allows the Attestation IMC/IMV pair to
+ do TPM 2.0 based attestation.
+
+- The behavior during IKEv2 exchange collisions has been improved/fixed in
+ several corner cases and support for TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND
+ notifies, as defined by RFC 7296, has been added.
+
+- IPsec policy priorities can be set manually (e.g. for high-priority drop
+ policies) and outbound policies may be restricted to a network interface.
+
+- The scheme for the automatically calculated default priorities has been
+ changed and now also considers port masks, which were added with 5.4.0.
+
+- FWD policies are now installed in both directions in regards to the traffic
+ selectors. Because such "outbound" FWD policies could conflict with "inbound"
+ FWD policies of other SAs they are installed with a lower priority and don't
+ have a reqid set, which allows kernel plugins to distinguish between the two
+ and prefer those with a reqid.
+
+- For outbound IPsec SAs no replay window is configured anymore.
+
+- Enhanced the functionality of the swanctl --list-conns command by listing
+ IKE_SA and CHILD_SA reauthentication and rekeying settings, and EAP/XAuth
+ identities and EAP types.
+
+- DNS servers installed by the resolve plugin are now refcounted, which should
+ fix its use with make-before-break reauthentication. Any output written to
+ stderr/stdout by resolvconf is now logged.
+
+- The methods in the kernel interfaces have been changed to take structs instead
+ of long lists of arguments. Similarly the constructors for peer_cfg_t and
+ child_cfg_t now take structs.
+
+
strongswan-5.4.0
----------------
+- Support for IKEv2 redirection (RFC 5685) has been added. Plugins may
+ implement the redirect_provider_t interface to decide if and when to redirect
+ connecting clients. It is also possible to redirect established IKE_SAs based
+ on different selectors via VICI/swanctl. Unless disabled in strongswan.conf
+ the charon daemon will follow redirect requests received from servers.
+
+- The ike: prefix enables the explicit configuration of signature scheme
+ constraints against IKEv2 authentication in rightauth, which allows the use
+ of different signature schemes for trustchain verification and authentication.
+
+- The initiator of an IKEv2 make-before-break reauthentication now suspends
+ online certificate revocation checks (OCSP, CRLs) until the new IKE_SA and all
+ CHILD_SAs are established. This is required if the checks are done over the
+ CHILD_SA established with the new IKE_SA. This is not possible until the
+ initiator installs this SA and that only happens after the authentication is
+ completed successfully. So we suspend the checks during the reauthentication
+ and do them afterwards, if they fail the IKE_SA is closed. This change has no
+ effect on the behavior during the authentication of the initial IKE_SA.
+
- For the vici plugin a Vici:Session Perl CPAN module has been added to allow
Perl applications to control and/or monitor the IKE daemon using the VICI
interface, similar to the existing Python egg or Ruby gem.
The port range must map to a port mask, though since the kernel does not
support arbitrary ranges.
+- The vici plugin allows the configuration of IPv4 and IPv6 address ranges
+ in local and remote traffic selectors. Since both the Linux kernel and
+ iptables cannot handle arbitrary ranges, address ranges are mapped to the next
+ larger CIDR subnet by the kernel-netlink and updown plugins, respectively.
+
+- Implemented IKEv1 IPv4/IPv6 address subnet and range identities that can be
+ used as owners of shared secrets.
