The shared stack available on GPFS storage and mounted at /software/lsstsw/stack on lsst-dev systems and the Verification Cluster has been re-initialized.
The new stack provides a refreshed Conda environment, with updated versions of Python and related libraries.
The new stack has been initialized with weekly w_2018_41, and will continue accumulating new weeklies as they are released.
The old shared stack can still be accessed at /software/lsstsw/stack3_20171023. This continues to provide access to older releases, dating back to October 2017.
Refer to the Developer Guide for information on using the shared stack.
