-- The sec-updater tool checks for security updates dpkg-based repositories
+- In compliance with RFCs 8221 and 8247 several algorithms were removed from the
+  default ESP/AH and IKEv2 proposals, respectively (3DES, Blowfish and MD5 from
+  ESP/AH, MD5 and MODP-1024 from IKEv2).  These algorithms may still be used in
+  custom proposals.
+
+- Added support for RSASSA-PSS signatures.  For backwards compatibility they are
+  not used automatically by default, enable charon.rsa_pss to change that.  To
+  explicitly use or require such signatures with IKEv2 signature authentication
+  (RFC 7427), regardless of whether that option is enabled, use ike:rsa/pss...
+  authentication constraints.
+
+- The pki tool can optionally sign certificates/CRLs with RSASSA-PSS via the
+  `--rsa-padding pss` option.
+
+- The sec-updater tool checks for security updates in dpkg-based repositories
   (e.g. Debian/Ubuntu) and sets the security flags in the IMV policy database
   accordingly. Additionally for each new package version a SWID tag for the
   given OS and HW architecture is created and stored in the database.

   reference hash measurements. This has been fixed by creating generic product
   versions having an empty package name.
 
+- A new timeout option for the systime-fix plugin stops periodic system time
+  checks after a while and enforces a certificate verification, closing or
+  reauthenticating all SAs with invalid certificates.
+
+- The IKE event counters, previously only available via ipsec listcounters, may
+  now be queried/reset via vici and the new swanctl --counters command. They are
+  provided by the new optional counters plugin.
+
+- Class attributes received in RADIUS Access-Accept messages may optionally be
+  added to RADIUS accounting messages.
+
+- Inbound marks may optionally be installed on the SA again (was removed with
+  5.5.2) by enabling the mark_in_sa option in swanctl.conf.
