Quote from release announce on the blog.

* Verify SSL certificates. Even though the client opened an encrypted
  connection to the server, it did not validate the certificate used. As a
  result, the client was open to MITM attacks. The new version will always
  validate the certificate first and refuse to connect to the server if there
  is a problem with it.

* Add support for soft links in UNIX systems. You can now use soft links in
  your project directories. This would be useful in cases where you have a
  large project and you would prefer to assign the localization files to
  multiple Transifex projects.

* Add support for local .transifexrc files. You can now have a .transifexrc
  file in your project directory. The entries in the file will override the
  ones from the main one. This would be useful in cases you would prefer to
  use a different set of credentials for a project than the ones you use for
  the rest of your projects in Transifex.

* Make the client more friendly to users in Windows. The .tx/config file now
  supports forward slashes for the paths in Windows, in accordance to what
  UNIX uses. As a result, people can now share a .tx/config irrespective of
  whether they use a UNIX-based system (like Linux and Mac OS X) or Windows.
