What’s Tails 2.6 RC1? It’s the first Release Candidate milestone in the development cycle of the next major version of the Debian-based GNU/Linux distribution, Tails 2.6, which should see the light of day sometime in mid-September, bringing many up-to-date technologies to keep users safe and secure while browsing the Internet. There are numerous improvements since Tails 2.5, so we’ll start with the biggest ones first. Tails 2.6 Release Candidate 1 (RC1) is based on Tor 0.2.8.6 to provide you with the best support for the Tor anonymous network, though the latest version is 0.2.8.7 and it should be implemented in the final Tails 2.6 release.
