We have released LibreSSL 2.7.1, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. This is the second release from the 2.7 series, which will be part of OpenBSD 6.3.

It includes the following changes from 2.7.0

* Fixed a bug in int_x509_param_set_hosts, calling strlen() if name
length provided is 0 to match the OpenSSL behaviour. Issue noticed
by Christian Heimes <christian@python.org>

* Fixed builds macOS 10.11 and older.

LibreSSL 2.7.1 also includes:

* Added support for many OpenSSL 1.0.2 and 1.1 APIs, based on
observations of real-world usage in applications. These are
implemented in parallel with existing OpenSSL 1.0.1 APIs - visibility
changes have not been made to existing structs, allowing code written
for older OpenSSL APIs to continue working.

* Extensive corrections, improvements, and additions to the
API documentation, including new public APIs from OpenSSL that had
no pre-existing documentation.

* Added support for automatic library initialization in libcrypto,
libssl, and libtls. Support for pthread_once or a compatible
equivalent is now required of the target operating system. As a
side-effect, minimum Windows support is Vista or higher.

* Converted more packet handling methods to CBB, which improves
resiliency when generating TLS messages.

* Completed TLS extension handling rewrite, improving consistency of
checks for malformed and duplicate extensions.

* Rewrote ASN1_TYPE_{get,set}_octetstring() using templated ASN.1.
This removes the last remaining use of the old M_ASN1_* macros
(asn1_mac.h) from API that needs to continue to exist.

* Added support for client-side session resumption in libtls.
A libtls client can specify a session file descriptor (a regular
file with appropriate ownership and permissions) and libtls will
manage reading and writing of session data across TLS handshakes.

* Improved support for strict alignment on ARMv7 architectures,
conditionally enabling assembly in those cases.

* Fixed a memory leak in libtls when reusing a tls_config.

* Merged more DTLS support into the regular TLS code path, removing
duplicated code.

* Many improvements to Windows Cmake-based builds and tests,
especially when targeting Visual Studio.

Thanks for all of the testing, suggestions, and updates from the porting community. We look forward to releasing a final stable version in a few
weeks.

The LibreSSL project continues improvement of the codebase to reflect modern, safe programming practices. We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible.
