`eups distrib install lsst_sims -t sims` will now get you version 2.3.5 of the lsst\_sims stack.

Changes since version 2.3.4:

sims\_movingObjects is no longer a part of lsst\_sims. If you want to install sims\_movingObjects, you will have to run `eups distrib install sims_movingObjects -t sims`. This means that lsst\_sims no longer depends on oorb or gfortran.

sims\_catUtils now includes a model for M, L, and T dwarf flares. This is accessible from the `VariabilityStars` mixin in

```auto
sims_catUtils/python/lsst/sims/catUtils/mixins/VariabilityMixin.py

```

imported with

```auto
from lsst.sims.catUtils.mixins import VariabilityStars

```

Various plot- and movie-generating scripts in sims\_maf are now python 3 compatible.

Note: You still need to make sure that your `~.astropy/config/astropy.cfg` file has `log_to_file=False` in order for the build to pass. This will hopefully be fixed in the next release.

This version is built against the weekly tag w.2017.18 of the DM stack.

Note that this distribution is now compatible with numpy 1.12 (while v13.0 was not).

An updated version 2.3.5.1 has been issued. The only change is that one of the unit tests in sims\_alertsim which suffers from a race condition has been marked as an `expectedFailure`. If you have successfully installed version 2.3.5, you do not need to do anything. If your installation failed on sims\_alertsim, try `eups distrib install lsst_sims -t sims` again.
