2011.12.25 -- Version 2.x-master
James Yonan (1):
      Added support for "on-link" routes on Linux client -- these are
      routes where the gateway is specified as an interface rather than
      an address.  This allows redirect-gateway to work on Linux clients
      whose connection to the internet is via a point-to-point link
      such as PPP.

      Note that at the moment, this capability is incompatible with
      the "redirect-gateway block-local" directive -- this is because
      the block-local directive blocks all traffic from the local LAN
      except for the local and gateway addresses.  Since a PPP link
      is essentially a subnet of two addresses, local and remote (i.e.
      gateway), the set of addresses that would be blocked by block-local
      is empty.  Therefore, the "redirect-gateway block-local" directive
      will be ignored on PPP links.

      To view the OpenVPN client's current determination of the default
      gateway, use this command:

        ./openvpn --show-gateway

  to Win7 and beyond.

2010.08.16 -- Version 2.2-beta2

* Windows security issue:
  Fixed potential local privilege escalation vulnerability in
  Windows service. The Windows service did not properly quote the
  executable filename passed to CreateService.  A local attacker
  with write access to the root directory C:\ could create an
  executable that would be run with the same privilege level as
  the OpenVPN Windows service.  However, since non-Administrative
  users normally lack write permission on C:\, this vulnerability
  is generally not exploitable except on older versions of Windows
  (such as Win2K) where the default permissions on C:\ would allow
  any user to create files there.
  Credit:  Scott Laurie, MWR InfoSecurity

* Added Python-based based alternative build system for Windows using
  Visual Studio 2008 (in win directory).

* When aborting in a non-graceful way, try to execute do_close_tun in
  init.c prior to daemon exit to ensure that the tun/tap interface is
  closed and any added routes are deleted.

* Fixed an issue where AUTH_FAILED was not being properly delivered
  to the client when a bad password is given for mid-session reauth,
  causing the connection to fail without an error indication.

* Don't advance to the next connection profile on AUTH_FAILED errors.

* Fixed an issue in the Management Interface that could cause
  a process hang with 100% CPU utilization in --management-client
  mode if the management interface client disconnected at the
  point where credentials are queried.

* Fixed an issue where if reneg-sec was set to 0 on the client,
  so that the server-side value would take precedence,
  the auth_deferred_expire_window function would incorrectly
  return a window period of 0 seconds.  In this case, the
  correct window period should be the handshake window
  period.

* Modified ">PASSWORD:Verification Failed" management interface
  notification to include a client reason string:

    >PASSWORD:Verification Failed: 'AUTH_TYPE' ['REASON_STRING']

* Enable exponential backoff in reliability layer
  retransmits.

* Set socket buffers (SO_SNDBUF and SO_RCVBUF) immediately after
  socket is created rather than waiting until after connect/listen.

* Management interface performance optimizations:

  1. Added env-filter MI command to perform filtering on env vars
     passed through as a part of --management-client-auth

  2. man_write will now try to aggregate output into larger blocks
     (up to 1024 bytes) for more efficient i/o

* Fixed minor issue in Windows TAP driver DEBUG builds
  where non-null-terminated unicode strings were being
  printed incorrectly.

* Fixed issue on Windows with MSVC compiler, where TCP_NODELAY support
  was not being compiled in.

* Proxy improvements:

  Improved the ability of http-auth "auto" flag to dynamically detect
  the auth method required by the proxy.

  Added http-auth "auto-nct" flag to reject weak proxy auth methods.

  Added HTTP proxy digest authentication method.

  Removed extraneous openvpn_sleep calls from proxy.c.

* Implemented http-proxy-override and http-proxy-fallback directives to make it
  easier for OpenVPN client UIs to start a pre-existing client config file with
  proxy options, or to adaptively fall back to a proxy connection if a direct
  connection fails.

* Implemented a key/value auth channel from client to server.

* Fixed issue where bad creds provided by the management interface
  for HTTP Proxy Basic Authentication would go into an infinite
  retry-fail loop instead of requerying the management interface for
  new creds.

* Added support for MSVC debugging of openvpn.exe in settings.in:

  # Build debugging version of openvpn.exe
  !define PRODUCT_OPENVPN_DEBUG

* Implemented multi-address DNS expansion on the network field of route
  commands.

  When only a single IP address is desired from a multi-address DNS
