Version 4.2.5¶

• Consistent logging of IKE and CHILD SAs at the audit (AUD) level.

• Improved the performance of the SQL-based virtual IP address pool
  by introducing an additional addresses table. The leases table
  storing only history information has become optional and can be
  disabled by setting charon.plugins.sql.lease_history = no in
  strongswan.conf.

• The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6
  and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels.

• management of different virtual IP pools for different
  network interfaces have become possible.

• fixed a bug which prevented the assignment of more than 256
  virtual IP addresses from a pool managed by an sql database.

• fixed a bug which did not delete own IPCOMP SAs in the kernel.
