Hi all!

Tor Browser 7.5 is ready for testing. Bundles can be found on:

https://people.torproject.org/~gk/builds/7.5-build3/

This is the first stable release in the 7.5 series. Apart from the usual Firefox security updates it contains some notable improvements compared to the 7.0 series. Here are the highlights:

1) We ship the first release in Tor's 0.3.2 series, 0.3.2.9.

2) We redesigned parts of the Tor Browser user interface. First, we improved Tor Launcher allowing users to configure bridges easier and making the whole bootstrap sequence less confusing and more streamlined. Second, we enhanced the security slider taking the user experience on mobile, as shown in Orfox, into account.

3) On the security side we enabled content sandboxing on Windows and fixed remaining issues on Linux that prevented printing to file from working properly. Additionally, we improved the compiler hardening on macOS and fixed holes in the W^X mitigation on Windows.

4) We finally moved away from Gitian/tor-browser-bundle as the base of our reproducible builds environment. Over the past weeks and months rbm/tor-browser-build got developed making it much easier to reproduce Tor Browser builds and to add reproducible builds for new platforms and architectures. This will allow us to ship 64bit bundles for Windows (currently in the alpha series available) and bundles for Android at the same day as the release for the current platforms/architectures is getting out.

Please give the bundles a try if you can and give us feedback in case things break. We are especially interested in hearing back from Windows users about possible issues with the sandboxing part.
