The OS X bundle won't work in the new OS X Mavericks by default. It is caused by some changes in the new operating system release. We know about this problem and are working on fixing it. If you are an affected user, you can try this workaround of placing absolute paths in the torrc file.

The bundles contain flash proxy and obfsproxy configured to run by default. If you want to use flash proxy, you will have to take the extra steps listed in the flash proxy howto.

These bundles contain the same hardcoded obfs2 bridge addresses as the previous bundles which may work for some jurisdictions but you are strongly advised to get new bridge addresses from BridgeDB.

Like the previous bundles, these contain Flashproxy and the Python version of Obfsproxy.

Flash proxy is a transport that uses proxies running in web browsers as access points into Tor. Obfsproxy is a pluggable transport that makes network traffic look unlike normal Tor traffic. Both of these technologies make it harder to block access to Tor. If you previously used the obfsproxy bundle, please upgrade to this bundle, which in addition to flash proxy has new obfsproxy bridges.

Flash proxy works differently from other pluggable transports, and you need to take extra steps to make it work. In particular, you will probably need to configure port forwarding in order to receive connections from browser proxies. There are instructions and hints on how to do that at this page: flash proxy howto.

These bundles contain the same hardcoded obfs2 bridge addresses as the previous bundles which may work for some jurisdictions but you are strongly advised to get new bridge addresses from BridgeDB: https://bridges.torproject.org/?transport=obfs2.

Furthermore, we are looking for feedback on how the bundles work. Please leave comments on the flash proxy usability wiki page or ticket #7824 with your experience, good or bad.

There are other ways you can help beyond testing the bundles. One is to run a bridge with pyobfsproxy. Another is to put the flash proxy badge on your web site or blog, or add it to your Wikipedia profile. If you want your browser to continue to be a proxy after a switch to an opt-in model, click the “Yes” button on the options page.

The Tor Cloud images for all the eight regions have been updated with a minor fix in the rc.local script. In addition, all private bridge images now include Obfsproxy. You will not need to start a new instance if you are already running a Tor Cloud instance with Ubuntu Precise.

The Tor Cloud images for all the seven regions have been updated to fix a bug found in the unattended-upgrades configuration. The normal bridge images have also been updated to include obfsproxy, which attempts to help users circumvent censorship by transforming the Tor traffic between the client and the bridge.

If you are already running a Tor Cloud bridge, you will need to either manually update your image, or set up a new Tor Cloud bridge and terminate the old one. If you decide not to take action, your image will fail to upgrade Tor correctly and will not be running as a bridge.

If you just want to fix the bug in the unattended-upgrades configuration, do the following; log on with SSH and edit /etc/apt/apt.conf.d/50unattended-upgrades to say precise instead of lucid.

The alpha Tor Browser Bundles have all been updated to the latest Tor 0.2.3.20-rc release candidate as well as being updated with some bugfixes. We're getting closer and closer to releasing the 0.2.3.x series as stable, so please give these bundles a lot of testing and help us shake out all of the remaining bugs! The regular bundles have also been updated.

The Tor Obfsproxy Browser Bundles have also been brought up to date with all of the same software as the regular alpha Tor Browser Bundles. These are still a work in progress, so please remember to report bugs! You can download them from the obfsproxy page.
