eups distrib install lsst_sims -t sims will now get you version 2.3.7 of the simulations stack. There is no new functionality in this version. However, it does fix a bug that was preventing the stack from building correctly on NFS-mounted systems.
This stack is built against the w.2017.33 weekly release of the DM stack.
There is also a copy of lsst_apps which can be installed via
eups distrib install lsst_apps -t sims and will be built against the same weekly.
