Version 4.6.2 of strongswan has been released. The changelog is as follows:

Trusted Network Connect
----------------------

- HSR master student Sansar Choinyambuu fully implemented the "TCG
  Attestation Platform Trust Service (PTS) Protocol: Binding to IF-M"
  standard (TLV-based messages only), making trustworthy remote
  attestation based on a Trusted Platform Module (TPM) of the Linux
  Integrity Measurement Architecture (IMA) or Intel TBOOT possible.

  http://linux-ima.sourceforge.net/

  Measurement reference values are automatically stored in an SQLite
  database that can be managed using the new ipsec attest command line
  tool.

  * PTS Integrity Measurement Verifier:

- Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3
  which supports IF-TNCCS 2.0 long message types, the exclusive flag
  and multiple IMC/IMV IDs. Both the TNC Client and Server as well as
  the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated.

  Input/Output-Octets attributes and has been tested against FreeRADIUS
  and Microsoft NPS.

  pkcs8 plugin.  This is the default format used by some OpenSSL tools
  since version 1.0.0 (e.g. openssl req with -keyout).
