Hi,

we are pleased to announce the first release candidate for the new hardened builds series. For now this is only for 64bit Linux machines. The bundle can be found on:

https://people.torproject.org/~gk/builds/5.5a4-hardened-build2/

This is basically a 5.5a4 build with two major differences:

1) It is built with a hardened Tor (Address Sanitizer (ASan), Undefined Behavior Sanitizer (UBSan), ...) and a hardened Firefox (ASan) to make exploitation of memory corruption bugs more difficult.

2) There are no bundles per locale we ship anymore. Rather, we included all languages we support into one bundle and let the user decide on start-up which locale should get used. This got done in https://bugs.torproject.org/12967 if you are interested in the details. We eventually plan to ship this feature in regular alphas and release builds (see: https://bugs.torproject.org/17400 for this task), too, thus your feedback here is extra welcome.

Georg
