+commit 42a8158b1dca6ee4ec1707176199cc36c26da7af
+Author: Michael Tokarev <mjt@tls.msk.ru>
+Date:   Fri May 4 16:41:47 2012 +0400
+
+    add (errnum) in front of windows error messages
+    
+    On localized, non-English versions of windows, it is
+    common to have two active charsets -- for console applications
+    and for GUI applications, together with localized error messages
+    returned by windows.  But two charsets are rarely compatible,
+    so sending the same byte sequence to console and to windows
+    event log makes one or another to be unreadable.  So at least
+    include the error number, this way it will be possible to
+    lookup the actual error test using external ways.

+
+    Document new proxy types.
+
+commit 5ae19cb0bb8dd6be1e9bcd560bb051f496a373ec
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Thu Apr 19 15:18:31 2012 +0200
+
+    Add support for proxying through an external command.
+    
+    Proxy type "exec" can be used to have an external script or binary set
+    up an outgoing connection. Standard input and output will be used to
+    exchange data with the external command. The variables REMOTEADDRESS and
+    REMOTEPORT are set to the intended destination address and port.
+
+commit fb5588856fa4dd6f140c72f7360302fe85b20c75

+Date:   Thu Apr 19 14:10:54 2012 +0200
+
+    Add support for SOCKS 5 proxies.
+    
+    This only covers outgoing TCP connections, and supports only
+    username/password authentication or no authentication.
+
+commit b58d95eb29662bce4388f95dbc5762b9e2999806
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Wed Apr 18 23:19:40 2012 +0200
+
+    Add basic support for SOCKS 4 and HTTP CONNECT proxies.
+    
+    When the Proxy option is used, outgoing connections will be made via the
+    specified proxy. There is no support for authentication methods or for having
+    the proxy forward incoming connections, and there is no attempt to proxy UDP.
+
+commit 84531fb6e621959e06519fdbb7f2a8f7578f66bd
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Mon Apr 16 01:57:25 2012 +0200
+
+    Allow broadcast packets to be sent directly instead of via the MST.
+    
+    When the "Broadcast = direct" option is used, broadcast packets are not sent
+    and forwarded via the Minimum Spanning Tree to all nodes, but are sent directly
+    to all nodes that can be reached in one hop.
+    
+    One use for this is to allow running ad-hoc routing protocols, such as OLSR, on
+    top of tinc.
+
+commit 535a55100bb77f107c85361e9f72a194e92bc8bc
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Thu Mar 29 16:45:25 2012 +0100
+
+    Allow environment variables to be used for Name.
+    
+    When the Name starts with a $, the rest will be interpreted as the name of an
+    environment variable containing the real Name. When Name is $HOST, but this
+    environment variable does not exist, gethostname() will be used to set the
+    Name. In both cases, illegal characters will be converted to underscores.
+
+commit 89f4574e0b1553c8e5dcbfc275e829a759b697f6
+Author: Guus Sliepen <guus@tinc-vpn.org>
+Date:   Mon Mar 26 14:46:09 2012 +0100
+
+    Add support for systemd style socket activation.
+    
+    If the LISTEN_FDS environment variable is set and tinc is run in the
+    foreground, tinc will use filedescriptors 3 to 3 + LISTEN_FDS for its listening
+    TCP sockets. For now, tinc will create matching listening UDP sockets itself.
+    
+    There is no dependency on systemd or on libsystemd-daemon.
+
+commit cc6aee784659bfbd21eb8d414e00a8f1a801cac4

+commit 16e6769feef21a5bf58f6022d990452987bb5efb
+Author: Anthony G. Basile <basile@opensource.dyc.edu>
+Date:   Mon Mar 26 06:29:40 2012 -0400
+
+    configure.in: fix AC_ARG_ENABLE and AC_ARG_WITH
+    
+    The current configure.in file does not correctly make use of these
+    macros.  The resulting configure file will therefore enable an item
+    even if --disable-FEATURE is given.  This patch restores the intended
+    behavior.
+

+Broadcast packets received from other nodes are never forwarded.

 For example, IPv4 subnets must be in a form like 192.168.1.0/24,
 where 192.168.1.0 is the network address and 24 is the number of bits set in the netmask.
 Note that subnets like 192.168.1.1/24 are invalid!
