Hamachi 2.2.0.633 VPN Service for PC Windows

* Added Korean translation

* Fixed a problem of automatic update on Vista

* Fixed a bug with double-clicking on the peer status indicator

* Fixed a bug with opening network chat window using a systray
notifcation

* Minor cosmetic UI changes

Added notifications in a form of system tray balloons; this feature
can be turned off via hamachi-override.ini
* Added an option of enabling diagnostic log from the Preferences,
System page. Maximum log size defaults to 16 Megs, split into two
8 MB files. The size and the verbosity of the log file is controlled
via hamachi-override.ini
* Added new languages - Croatian and Hungarian. Serbian is on its way.
* Updated a number of existing translations
* Modified Hamachi adapter driver to use stack space more rationally;
all bulky temporary variables are now allocated off the stack
* Modified the installer to put Hamachi adapter _last_ on Windows'
"adapter binding list"
* Modified the installer to disable "DNS updates" on Hamachi adapter,
which is another way of saying that 5.x.x.x address should NOT now
be getting an A record if the machine's running a DNS server
* Modified the installer to set DefaultGateway on the Hamachi adapter
to 5.0.0.1 and its InterfaceMetric - to 9000. This Vista-specific
fix; non-Vista installations are not affected
* Fixed "stuck in a reconnecting mode" issue
* Fixed UPnP code to understand broken dialects of HTTP/1.1 spoken
by some home routers
* Fixed local value of peer's MAC address being different from the
value used by the peer itself (affects IPX connectivity)
* Fixed "Failed to connect to the adapter" problem by -
# making Hamachi select any suitable adapter if the default one is
not available
# making the installer force Windows to name all newly added items
in a Network Connections folder (affects machines that do not use
Windows Explorer as a default shell)
* Fixed the problem with per-peer information not being saved properly
when Hamachi is running as a service
* Fixed the problem with "Block Vulnerable Services" option not working
properly
* Fixed cosmetic UI issues (language, wording, formatting, etc)

- Modified the driver to work around Comodo firewall's bug of not
coping with zero-checksum'ed UDP packets

- Fixed the crash condition that occurs when starting Hamachi on
computers that have previously run 0.9.x.x versions of Hamachi

- Fixed per-peer preferences sometimes not getting properly saved
when running Hamachi as a service

- Fixed TCP peer-to-peer tunneling sometimes not working between
1.0.2.0 clients

- Resolved Vista compatibility issues.

Hamachi can now be run under non-privileged Windows accounts
(not only on Vista, but on earlier Windows versions as well).
Full administrative access is still required to install the
application as it adds the device driver to the system.

Note: this release includes updated Hamachi network card
driver. If you are updating from earlier Hamachi version,
it may be required to re-reset your firewalling software
and re-add the Hamachi adapter back into the 'trusted zone'.

- Introduced a concept of "layer 3 tunneling domains".

Starting with this version Hamachi can now service more than
one virtual Hamachi adapter. Each adapter is associated with
its own "tunnelling domain", and each Hamachi peer can be
assigned to one of these domains.

Adapters may be configured to use arbitrary IP addresses and
peers may be assigned "VPN" (or "Layer 3") addresses that are
different from their default 5.x.x.x IPs.

Peers in one tunneling domain can access local machine only
through domain's network adapter. This in particular means
that Hamachi can now be configured to use one adapter for
communicating with "trusted" peers and, for example, have
Windows File Sharing installed and enabled in the adapter's
stack itself. And it then can use second adapter to talk to
say gaming peers, and the adapter may not even have the WFS
module installed.

Custom addressing also enables a variety of complex LAN-to-LAN
configurations.

This is a premium feature.

- Introduced per-tunnel compression / encryption settings.

Starting with this version it is now possible to control
traffic encryption and compression on per-tunnel basis.

In order for the compression to be ON, both peers need to
select it to be ON. If settings are both OFF or if they do
not match, the compression will remain disabled.

Similarly, for the encryption to be OFF, both peers need to
have it set to OFF.

This is a premium feature.

- Introduced per-tunnel traffic forwarding policies.

It is now possible to control how Hamachi handles forwarded
traffic. This is closely related to a "routed tunneling"
mode and it specifies if Hamachi accepts or denies locally
and remotely forwarded traffic.

Earlier versions accepted all forwarded traffic to/from
all peers when the "routed tunneling" mode was enabled.

With this version the routed tunneling setting may be
narrowed down to a specific peer and, for example, further
restricted it to traffic that flows between local machine
and the peer LAN, i.e. force Hamachi to drop the traffic
that is forwarded from local LAN to the peer.

- Added "Advanced" per-peer configuration dialog.

Per-peer tunnel settings can now controlled from Advanced
configuration dialog that is accessible via "Advanced" item
of the peer's right-click menu.

The menu item is hidden by default and it can be enabled by
ticking an check box on Preferences / Window page.

The dialog allows controlling peer's -
- tunneling domain
- VPN IP address
- VPN IP alias (previously specified in aliases.txt)
- encryption and compression settings
- local and remote forwarding policies

The dialog also allows changing default, global values of
these settings.

- Modified Hamachi to automatically re-establish UDP tunnels when
detecting possible tunnel failure. This compliments similar TCP
tunnel behaviour already implemented in earlier versions.

- Modified Hamachi to automatically downgrade back to the basic
license once the trial license expires and the warning message
is displayed and acknowledged.

- Resolved crash condition related to the chat operation.

- Assorted tweaks and fixes to the application and the installer.

- Resolved an issue with chat feature getting incorrectly disabled
between peers that both have it enabled.
- Resolved an issue with URLs not being clickable in chat windows.

Re-created the Hamachi driver digital signature. It should now
be possible to install it on Vista x64 without disabling "driver
signature enforcement" on a boot.
- Added hamachi-override.ini options to allow changing the text and
the background colors in Hamachi chat windows. This is done by adding
the following entries to hamachi-override.ini -
----ChatColorLogBack
----ChatColorLogFore
----ChatColorLogSelf
----ChatColorLogPeer
----ChatColorLogSystem
----ChatColorLogNetwork
----ChatColorLogHistory
Back is a color of a background of both the top and the bottom chat
panes. Fore is a text color of the bottom pane. Self is a color of
local IMs in the top pane, Peer - of the remote ones. System is a
color of system messages (such as 'xyz is online'). Network is a color
of administrative messages when in a network chat mode. History is a
color of a chat log when it is loaded in a top pane via 'Load History'
right-click menu option.
is in a hexadecimal format - RRGGBB or RGB - the same format
used by HTML, CSS and a multitude of graphical editors. Red is FF0000
or F00, cyan is 00FFFF or 0FF, white is FFF, black is 000, etc
- Fixed a problem with clients sometimes not being able to communicate
after F5 was used to rebuild an existing _working_ tunnel.
- Fixed chat module to gracefully fail sending IMs when the remote
peer disables Chat via its Hamachi Preferences.
- Updated few translations - Italian, Polish, Serbian and Ukrainian.
- Handful of small UI tweaks

- Fixed a bug in handling the tear down of TCP tunnels.

* Fixed a bug that might've caused an application error under
certain conditions when using SSL/proxy connection

* Cosmetic UI changes, updated copyright string in the driver

- Added support for using Hamachi from behind Web proxies and
from locations that restrict TCP and UDP connectivity.
- Introduced 30 day trial licenses. These licenses can be used
free of charge once per every Hamachi account and once per
every computer Hamachi is installed on.
- Reworked Hamachi Preferences to put connection configuration
settings on a front page of Preferences under 'Detailed
configuration..' button. In particular, Magic Option has been
renamed and moved from System page to this new configuration
dialog.
- Fixed a number of small and cosmetic bugs, including '-no-splash'
option not working.

- Modified Hamachi to fall back to low-speed relays if direct p2p connection is not possible. Earlier versions required explicit opt-in for this feature.
- Per-tunnel bandwidth for low-speed relaying has been increased to 8 KB/sec. Strictly speaking this is a relay-side option, but it is listed here to provide a context for the previous item.
- Added one-time warning messages that are displayed when Hamachi encounters 'unreachable' or 'low-speed relayed' tunnels for the first time. These messages link to the following web page that explains details of each condition -
- Added an option for compressing peer-to-peer traffic. The algorithm used is a standard 'deflate' (also used in RFC'd IPCOMP, TLS and others). Depending on the type of the traffic the compression rate may be as high as 50-60%.
- Tunnel compression is a global client-side preference. The traffic is compressed between any two clients that have this option enabled. This is premium feature. See 1.0.0.47 release notes for details.
- Updated logo images in Hamachi installer.
- Singed all binaries with LogMeIn publisher certificate. This is the reason for installation package size increase.
- Added a number of provisions to improve compatibility with Vista. Hamachi should now install on recent Vista betas without any external tweak.

*** NOTE that there is a known bug in Vista that may result in Hamachi's window getting all screwed up when it is resized or moved. This is a bug in Aero (transparent glassy window thingy), it is not Hamachi-specific, Microsoft has been notified.

- Fixed a problem with peer's status indicator vanishing
from the list under certain conditions
- Fixed a problem with custom labels not being saved when
Hamachi was running in a service mode
- Added p2p key exchange caching mechanism to help Hamachi deal
with slow or very slow p2p links. Hamachi now remembers its
replies for each step of the KE and can process duplicate p2p
ke packets without recomputing RSA/DH variable from scratch.
- Reworked built-in proxy to better cope with slow links on
either side of proxied HTTP connection.

- stability fixes for few minor/low-profile bugs.

- Stability fix for a rare crash condition occuring when
Hamachi is entering reconnecting state.
- GUI fix for Hamachi service GUI using wrong format for
IP address in peer's tooltips.
- Added a right-click chat window menu option for loading
chat history from a file.

* Re-enabled 'one-click join' feature that was accidently
disable in 1.0.0.57 due to run-as-a-service rework.
