A bugfix version.
Changelog from the mailing list:

* libgnutls: DTLS blocking API is more robust against infinite blocking,
and will notify of more possible timeouts.

* libgnutls: corrected regression with Camellia-256-GCM cipher. Reported
by Manuel Pegourie-Gonnard.

* libgnutls: Introduced the GNUTLS_NO_SIGNAL flag to gnutls_init(). That
allows to disable SIGPIPE for writes done within gnutls.

* libgnutls: Enhanced the PKCS #7 API to allow signing and verification
of structures. API moved to gnutls/pkcs7.h header.

* certtool: Added options to generate PKCS #7 bundles and signed
structures.
