The “shared stack” on lsst-dev has been updated to reflect the changes to the Conda environment described in [RFC-584](https://jira.lsstcorp.org/browse/RFC-584).

The new stack contains weeklies from `w_2019_12` onwards. It is available at `/software/lsstsw/stack_20190330`.

The old stack contains weeklies from `w_2018_41` to `w_2019_12`, as well as the `v17_0` and `v17_0_1` releases. It will no longer be updated. It is available at `/software/lsstsw/stack_20181012`.

The symbolic link `/software/lsstsw/stack` will always point to the most recent shared stack.

Refer to the [Developer Guide](https://developer.lsst.io/v/DM-18672/services/lsst-dev.html#lsst-dev-loadlsst) for further details.

May we have `git_lfs` installed with this new shared stack, like `stack_20181012` before, please? That was very useful.

Of course; done.

I’ll keep a note on this thread of additional packages that get installed into the shared stack in response to requests like this one, so that we can track whether we want to keep adding them on an ad-hoc basis in future, or have them provided by the system or by the standard Conda environment. So far, we have:

- cx\_Oracle, requested by @natelust, installed using Conda;
- Git LFS, requested by @hsinfang, declared using EUPS;
- dask, requested by @sophiereed, installed using Conda;
- pyarrow, requested by @timothydmorton, installed using Conda;
- ipdb, requested by @natelust, installed using Conda (`-c conda-forge`);
- ~~pytorch, requested by @fred3m, installed using Conda (`-c pytorch`)~~ (removed for causing segfaults).

Would it be possible to have ipdb installed by default as well? It is really useful.

Done. Please let me know if it works for you.
