New in Proxifier 2.0.1 (Aug 13, 2012)

  • Improved UI:
  • The new version features a significantly improved user interface. The connection list provides much more detailed information about the connections including: selected proxy server, matched rule, connection status with color indication, user name and process ID. All additional information is displayed only when needed so UI remains clean and easy to read.
  • Proxifier log messages are now more detailed as well. They include all new parameters listed in the above paragraph. Additionally a number of new messages were introduced. Now Proxifier can be configured to output DNS requests, rules processing messages and more. Verbosity of the output can be changed via the Log menu. It is possible to set different log levels for screen and file output.
  • Brand New Concept for Proxy Settings and Rules:
  • The core of Proxifier configuration has been significantly redesigned and improved. Now you can specify independent multiple proxy servers in Profile->Proxy Settings... It is also possible to create multiple proxy chains and manipulate them via the new UI.
  • The new version allows you to assign different proxies/chains for different rules Profile->Proxification Rules... Thus each rule has an individual action that tells Proxifier to process the connections through a proxy or chain, to block the connection or to open it directly.
  • Rule configuration has been redesigned to be much more comprehensive and flexible. Applications and target hosts can be specified as wildcards e.g. fire*, 192.168.1.*, etc.
A very important improvement is DNS names support. Thus the target can be specified by its host name mask such as *.example.com.
  • 

  • Profiles:
  • Management and organization of Proxifier configuration files (*.prx) has been improved and the function has been renamed to Profiles.
  • Fast switching between profiles.
  • Password encryption Profile->Advanced->Password Encryption...
  • XML format of profile files (*.ppx).
  • 
  • 
  • Proxifier Profiles of Windows and Mac versions are fully compatible so you can easily move configuration between the platforms.
  • New Network Engine:
  • The network engine of Proxifier for Mac has been completely rewritten. It improves the overall performance of the program, provides full IPv6 support and better hostname processing. No installation is needed anymore. You can simply unpack Proxifier to any folder on your Mac and you are all set.
  • The new version features a number of other improvements. Overlay they significant improves user experience.
  • DNS over Proxy Improvements:
  • Proxifier can now automatically detect DNS settings and select an appropriate mode that matches the current network environment. I.e. it will resolve hostname through proxy if local DNS is unavailable and vice versa.
  • 
  • 
  • Now you can specify the hostnames that should be resolved with local DNS when Proxifier is configured to process hostnames through a proxy. This feature is useful when you need to work with LAN and Internet connections at the same time.
  • Quick Start, Migration and Breaking Changes:
  • The new version introduces a number of changes but the core features remain the same.
  • Specify a proxy server at Profile->Proxy Settings...
  • Configure rules at Profile->Proxification Rules... to match your scenario.
  • TCP connections that match the rules will be processed through the proxy you have specified.
  • Proxifier v2 does not import old settings automatically on start. To convert old configuration file of Proxifier v1 (*.prx) please use the File->Import Profile... command.
