I would like to announce that rubin\_sim v1.3.0 has been released. A major update with this release is that the data associated with rubin\_sim has been updated to use a newly released 1.9 set of throughput curves. This a… --- ## [Announcing rubin\_sim version 1.0](https://www.rubin.community/t/announcing-rubin-sim-version-1-0/7261)

We are happy to announce the release of rubin\_sim version 1.0. This was mostly a large refactor to get the code in better compliance with python style standards. As such, there were numerous name changes that will not be… --- ## [How to cite LSST throughputs repo](https://www.rubin.community/t/how-to-cite-lsst-throughputs-repo/7106)
