Hello, Shadow versions 1.11.0 and 1.11.1 are now released! https://github.com/shadow/shadow/releases/tag/v1.11.0 https://github.com/shadow/shadow/releases/tag/v1.11.1 These versions represent a huge engineering effort to provide transparent support for plug-ins that use pthreads and that make blocking IO or system calls. We are using a fork of GNU portable threads (http://www.gnu.org/software/pth/) to enable this thread and blocking support. Shadow now literally just calls `tor_main()` and handles the rest internally. More details can be found in the release notes here: http://mailman.cs.umn.edu/archives/shadow-support/2016-January/000475.html All the best, Rob
