+Version 2.4.0
+=============
+
+
+New features
+------------
+Seamless client IP/port floating
+    Added new packet format P_DATA_V2, which includes peer-id. If both the
+    server and client support it, the client sends all data packets in
+    the new format. When a data packet arrives, the server identifies peer
+    by peer-id. If peer's ip/port has changed, server assumes that
+    client has floated, verifies HMAC and updates ip/port in internal structs.
+    This allows the connection to be immediatly restored, instead of requiring
+    a TLS handshake before the server accepts packets from the new client
+    ip/port.
+
+Data channel cipher negotiation
+    Data channel ciphers (``--cipher``) are now by default negotiated.  If a
+    client advertises support for Negotiable Crypto Parameters (NCP), the
+    server will choose a cipher (by default AES-256-GCM) for the data channel,
+    and tell the client to use that cipher.  Data channel cipher negotiation
+    can be controlled using ``--ncp-ciphers`` and ``--ncp-disable``.
+
+    A more limited version also works in client-to-server and server-to-client
+    scenarios where one of the end points uses a v2.4 client or server and the
+    other side uses an older version.  In such scenarios the v2.4 side will
+    change to the ``--cipher`` set by the remote side, if permitted by by
+    ``--ncp-ciphers``.  For example, a v2.4 client with ``--cipher BF-CBC``
+    and ``ncp-ciphers AES-256-GCM:AES-256-CBC`` can connect to both a v2.3
+    server with ``cipher BF-CBC`` as well as a server with
+    ``cipher AES-256-CBC`` in its config.  The other way around, a v2.3 client
+    with either ``cipher BF-CBC`` or ``cipher AES-256-CBC`` can connect to a
+    v2.4 server with e.g. ``cipher BF-CBC`` and
+    ``ncp-ciphers AES-256-GCM:AES-256-CBC`` in its config.  For this to work
+    it requires that OpenVPN was built without disabling OCC support.
+
+AEAD (GCM) data channel cipher support
+    The data channel now supports AEAD ciphers (currently only GCM).  The AEAD
+    packet format has a smaller crypto overhead than the CBC packet format,
+    (e.g. 20 bytes per packet for AES-128-GCM instead of 36 bytes per packet
+    for AES-128-CBC + HMAC-SHA1).
+
+ECDH key exchange
+    The TLS control channel now supports for elliptic curve diffie-hellmann
+    key exchange (ECDH).
+
+Dualstack round-robin DNS client connect
+    Instead of only using the first address of each ``--remote`` OpenVPN
+    will now try all addresses (IPv6 and IPv4) of a ``--remote`` entry.
+
+Support for providing IPv6 DNS servers
+    A new DHCP sub-option ``DNS6`` is added alongside with the already existing
+    ``DNS`` sub-option.  This is used to provide DNS resolvers available over
+    IPv6.  This may be pushed to clients where `` --up`` scripts and ``--plugin``
+    can act upon it through the ``foreign_option_<n>`` environment variables.
+
+    Support for the Windows client picking up this new sub-option is added,
+    however IPv6 DNS resolvers need to be configured via ``netsh`` which requires
+    administrator privileges unless the new interactive services on Windows is
+    being used.  If the interactive service is used, this service will execute
+    ``netsh`` in the background with the proper privileges.
+
+New improved Windows Background service
+    The new OpenVPNService is based on openvpnserv2, a complete rewrite of the OpenVPN
+    service wrapper. It is intended for launching OpenVPN instances that should be
+    up at all times, instead of being manually launched by a user. OpenVPNService is
+    able to restart individual OpenVPN processes if they crash, and it also works
+    properly on recent Windows versions. OpenVPNServiceLegacy tends to work poorly,
+    if at all, on newer Windows versions (8+) and its use is not recommended.
+
+New interactive Windows service
+    The installer starts OpenVPNServiceInteractive automatically and configures
+    it to start	at system startup.
+
+    The interactive Windows service allows unprivileged users to start
+    OpenVPN connections in the global config directory (usually
+    C:\\Program Files\\OpenVPN\\config) using OpenVPN GUI without any
+    extra configuration.
+
+    Users who belong to the built-in Administrator group or to the
+    local "OpenVPN Administrator" group can also store configuration
+    files under %USERPROFILE%\\OpenVPN\\config for use with the
+    interactive service.
+
+redirect-gateway ipv6
+    OpenVPN has now feature parity between IPv4 and IPv6 for redirect
+    gateway including the handling of overlapping IPv6 routes with
+    IPv6 remote VPN server address.
+
+LZ4 Compression and pushable compression
+    Additionally to LZO compression OpenVPN now also supports LZ4 compression.
+    Compression options are now pushable from the server.
+
+Filter pulled options client-side: pull-filter
+    New option to explicitly allow or reject options pushed by the server.
+    May be used multiple times and is applied in the order specified.
+
+Per-client remove push options: push-remove
+    New option to remove options on a per-client basis from the "push" list
+    (more fine-grained than ``--push-reset``).
+
+Http proxy password inside config file
+    Http proxy passwords can be specified with the inline file option
+    ``<http-proxy-user-pass>`` .. ``</http-proxy-user-pass>``
+
+Windows version detection
+    Windows version is detected, logged and possibly signalled to server
+    (IV_PLAT_VER=<nn> if ``--push-peer-info`` is set on client).
+
+Authentication tokens
+    In situations where it is not suitable to save user passwords on the client,
+    OpenVPN has support for pushing a --auth-token since v2.3.  This option is
+    pushed from the server to the client with a token value to be used instead
+    of the users password.  For this to work, the authentication plug-in would
+    need to implement this support as well.  In OpenVPN 2.4 --auth-gen-token
+    is introduced, which will allow the OpenVPN server to generate a random
+    token and push it to the client without any changes to the authentication
+    modules.  When the clients need to re-authenticate the OpenVPN server will
+    do the authentication internally, instead of sending the re-authentication
+    request to the authentication module .  This feature is especially
+    useful in configurations which use One Time Password (OTP) authentication
+    schemes, as this allows the tunnel keys to be renegotiated regularly without
+    any need to supply new OTP codes.
+
+keying-material-exporter
+    Keying Material Exporter [RFC-5705] allow additional keying material to be
+    derived from existing TLS channel.
+
+Mac OS X Keychain management client
+    Added contrib/keychain-mcd which allows to use Mac OS X keychain
+    certificates with OpenVPN.
+
+Android platform support
+    Support for running on Android using Android's VPNService API has been added.
+    See doc/android.txt for more details. This support is primarily used in
+    the OpenVPN for Android app (https://github.com/schwabe/ics-openvpn)
+
+AIX platform support
+    AIX platform support has been added. The support only includes tap
+    devices since AIX does not provide tun interface.
+
+Control channel encryption (``--tls-crypt``)
+    Use a pre-shared static key (like the ``--tls-auth`` key) to encrypt control
+    channel packets.  Provides more privacy, some obfuscation and poor-man's
+    post-quantum security.
+
+Asynchronous push reply
+    Plug-ins providing support for deferred authentication can benefit from a more
+    responsive authentication where the server sends PUSH_REPLY immediately once
+    the authentication result is ready, instead of waiting for the the client to
+    to send PUSH_REQUEST once more.  This requires OpenVPN to be built with
+    ``./configure --enable-async-push``.  This is a compile-time only switch.
+
+
+Deprecated features
+-------------------
+- ``--key-method 1`` is deprecated in 2.4 and will be removed in 2.5.  Migrate
+  away from ``--key-method 1`` as soon as possible.  The recommended approach
+  is to remove the ``--key-method`` option from the configuration files, OpenVPN
+  will then use ``--key-method 2`` by default.  Note that this requires changing
+  the option in both the client and server side configs.
+
+- CRLs are now handled by the crypto library (OpenSSL or mbed TLS), instead of
+  inside OpenVPN itself.  The crypto library implementations are more strict
+  than the OpenVPN implementation was.  This might reject peer certificates
+  that would previously be accepted.  If this occurs, OpenVPN will log the
+  crypto library's error description.
+
+- ``--tls-remote`` is removed in 2.4, as indicated in the 2.3 man-pages.  Similar
+  functionality is provided via ``--verify-x509-name``, which does the same job in
+  a better way.
+
+- ``--compat-names`` and ``--no-name-remapping`` were deprecated in 2.3 and will
+  be removed in 2.5.  All scripts and plug-ins depending on the old non-standard
+  X.509 subject formatting must be updated to the standardized formatting.  See
+  the man page for more information.
+
+- ``--no-iv`` is deprecated in 2.4 and will be removed in 2.5.
+
+User-visible Changes
+--------------------
+- When using ciphers with cipher blocks less than 128-bits,
+  OpenVPN will complain loudly if the configuration uses ciphers considered
+  weak, such as the SWEET32 attack vector.  In such scenarios, OpenVPN will by
+  default renegotiate for each 64MB of transported data (``--reneg-bytes``).
+  This renegotiation can be disabled, but is HIGHLY DISCOURAGED.
+
+- For certificate DNs with duplicate fields, e.g. "OU=one,OU=two", both fields
+  are now exported to the environment, where each second and later occurrence
+  of a field get _$N appended to it's field name, starting at N=1.  For the
+  example above, that would result in e.g. X509_0_OU=one, X509_0_OU_1=two.
+  Note that this breaks setups that rely on the fact that OpenVPN would
+  previously (incorrectly) only export the last occurence of a field.
+
+- ``proto udp`` and ``proto tcp`` now use both IPv4 and IPv6. The new
+  options ``proto udp4`` and ``proto tcp4`` use IPv4 only.
+
+- ``--sndbuf`` and ``--recvbuf`` default now to OS defaults instead of 64k
+
+- OpenVPN exits with an error if an option has extra parameters;
+  previously they were silently ignored
+
+- ``--tls-auth`` always requires OpenVPN static key files and will no
+  longer work with free form files
+
+- ``--proto udp6/tcp6`` in server mode will now try to always listen to
+  both IPv4 and IPv6 on platforms that allow it. Use ``--bind ipv6only``
+  to explicitly listen only on IPv6.
+
+- Removed ``--enable-password-save`` from configure. This option is now
+  always enabled.
+
+- Stricter default TLS cipher list (override with ``--tls-cipher``), that now
+  also disables:
+
+  * Non-ephemeral key exchange using static (EC)DH keys
+  * DSS private keys
+
+- mbed TLS builds: changed the tls_digest_N values exported to the script
+  environment to be equal to the ones exported by OpenSSL builds, namely
+  the certificate fingerprint (was the hash of the 'to be signed' data).
+
+- mbed TLS builds: minimum RSA key size is now 2048 bits.  Shorter keys will
+  not be accepted, both local and from the peer.
+
+- ``--connect-timeout`` now specifies the timeout until the first TLS packet
+  is received (identical to ``--server-poll-timeout``) and this timeout now
+  includes the removed socks proxy timeout and http proxy timeout.
+
+  In ``--static`` mode ``connect-timeout`` specifies the timeout for TCP and
+  proxy connection establishment
+
+- ``--connect-retry-max`` now specifies the maximum number of unsuccessful
+  attempts of each remote/connection entry before exiting.
+
+- ``--http-proxy-timeout`` and the static non-changeable socks timeout (5s)
+  have been folded into a "unified" ``--connect-timeout`` which covers all
+  steps needed to connect to the server, up to the start of the TLS exchange.
+  The default value has been raised to 120s, to handle slow http/socks
+  proxies graciously.  The old "fail TCP fast" behaviour can be achieved by
+  adding "``--connect-timeout 10``" to the client config.
+
+- ``--http-proxy-retry`` and ``--sock-proxy-retry`` have been removed. Proxy connections
+  will now behave like regular connection entries and generate a USR1 on failure.
+
+- ``--connect-retry`` gets an optional second argument that specifies the maximum
+  time in seconds to wait between reconnection attempts when an exponential
+  backoff is triggered due to repeated retries. Default = 300 seconds.
+
+- Data channel cipher negotiation (see New features section) can override
+  ciphers configured in the config file.  Use ``--ncp-disable`` if you do not want
+  this behavior.
+
+- All tun devices on all platforms are always considered to be IPv6
+  capable. The ``--tun-ipv6`` option is ignored (behaves like it is always
+  on).
+
+- On the client side recursively routed packets, which have the same destination
+  as the VPN server, are dropped. This can be disabled with
+  --allow-recursive-routing option.
+
+- On Windows, when the ``--register-dns`` option is set, OpenVPN no longer
+  restarts the ``dnscache`` service - this had unwanted side effects, and
+  seems to be no longer necessary with currently supported Windows versions.
+
+- If no flags are given, and the interactive Windows service is used, "def1"
+  is implicitly set (because "delete and later reinstall the existing
+  default route" does not work well here).  If not using the service,
+  the old behaviour is kept.
+
+- OpenVPN now reloads a CRL only if the modication time or file size has
+  changed, instead of for each new connection.  This reduces the connection
+  setup time, in particular when using large CRLs.
+
+- OpenVPN now ships with more up-to-date systemd unit files which take advantage
+  of the improved service management as well as some hardening steps.  The
+  configuration files are picked up from the /etc/openvpn/server/ and
+  /etc/openvpn/client/ directories (depending on unit file).  This also avoids
+  these new unit files and how they work to collide with older pre-existing
+  unit files.
+
+- Using ``--no-iv`` (which is generally not a recommended setup) will
+  require explicitly disabling NCP with ``--disable-ncp``.  This is
+  intentional because NCP will by default use AES-GCM, which requires
+  an IV - so we want users of that option to consciously reconsider.
+
+
+Maintainer-visible changes
+--------------------------
+- OpenVPN no longer supports building with crypto support, but without TLS
+  support.  As a consequence, OPENSSL_CRYPTO_{CFLAGS,LIBS} and
+  OPENSSL_SSL_{CFLAGS,LIBS} have been merged into OPENSSL_{CFLAGS,LIBS}.  This
+  is particularly relevant for maintainers who build their own OpenSSL library,
+  e.g. when cross-compiling.
+
+- Linux distributions using systemd is highly encouraged to ship these new unit
+  files instead of older ones, to provide a unified behaviour across systemd
+  based Linux distributions.
+
+- With OpenVPN v2.4, the project has moved over to depend on and actively use
+  the official C99 standard (-std=c99).  This may fail on some older compiler/libc
+  header combinations.  In most of these situations it is recommended to
+  use -std=gnu99 in CFLAGS.  This is known to be needed when doing
+  i386/i686 builds on RHEL5.

-Returns a 32-bit value.  Every bit of the key affects every bit of

-About 36+6len instructions.
-
-The best hash table sizes are powers of 2.  There is no need to do

-use a bitmask.  For example, if you need only 10 bits, do
-  h = (h & hashmask(10));
-In which case, the hash table should have hashsize(10) elements.
-
-If you are hashing n strings (uint8_t **)k, do it like this:
-  for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);

-* If mix() is run forward, every bit of c will change between 1/3 and
-  2/3 of the time.  (Well, 22/100 and 78/100 for some 2-bit deltas.)
-mix() was built out of 36 single-cycle latency instructions in a

-      a -= b; 
-      a -= c; x = (c>>13);

-      c -= b; x = (b>>13);

-  Unfortunately, superscalar Pentiums and Sparcs can't take advantage 
-  of that parallelism.  They've also turned some of those single-cycle
-  latency instructions into multi-cycle latency instructions.  Still,
-  this is the fastest good hash I could find.  There were about 2^^68
-  to choose from.  I only looked at a billion or so.
