OpenVPN Release 2.7_beta1

version.m4, ChangeLog, Changes.rst

Changes.rst has not received an "2.7_beta1" section - it has the
"highlevel" overview of what is new in 2.7, but for alpha/beta releases
it's better to look at git log to see what has been added/fixed.

New features alpha3 -> beta1 are
  - a large number of signed/unsigned related warnings have been fixed
  - bugfixes in --dns-updown script for linux systems using resolvconf
  - rewrite of the management interface "bytecount" infastructure to better
    interact with DCO
  - PUSH_UPDATE server support (via management interface)
  - introduction of route_redirect_gateway_ipv4 and _ipv6 env variables
  - speeding up t_client tests by reducing per-test startup delay 3s -> 1s

The biggest noticeable difference in beta1 is the reformatting using
clang-format, leaving uncrustify as that wasn't stable across versions.

+- Apply more checks to incoming TLS handshake packets before creating
+  new state - namely, verify message ID / acked ID for "valid range for
+  an initial packet".  This fixes a problem with clients that float
+  very early but send control channel packet from the pre-float IP
+  (Github: OpenVPN/openvpn#704).
+
+- Use of ``--dh dh2048.pem`` in all sample configs has been replaced
+  with ``--dh none``.  The ``dh2048.pem`` file has been removed, and
+  has been replaced with ``ffdhe2048.pem`` for the benefit of the
+  t_server_null test (to test all variants of ``--dh``).
+
+- the startup delay in ``t_client.sh`` has been reduced from 3s to 1s,
+  making a noticeable difference for setups with many tests.
+
+- changed from using ``uncrustify`` for code formatting and pre-commit checks
+  to ``clang-format``.  This reformatted quite a bit of code, and requires
+  that regular committers change their pre-commit checks accordingly.
