+## v0.5.1 — 2023-09-09
+
+### Added
+
+- Added `--sort/--no-sort` flag to cli. Default is to sort dependecies. This
+  fixes issues with changing order in `pyproject.toml` leading to different yaml
+  files.
+
+### Changed
+
+- Changed structure of the repo to better support some third party tools.
+- Moved nox environments from `.nox` to `.nox/{project-name}/envs`. This fixes
+  issues with ipykernel giving odd names for locally installed environments.
+- Moved repo specific dot files to the `config` directory (e.g.,
+  `.noxconfig.toml` to `config/userconfig.toml`). This cleans up the top level
+  of the repo.
+- added some support for using `nbqa` to run mypy/pyright on notebooks.
+- Added ability to bootstrap development environment using pipx. This should
+  simplify initial setup. See Contributing for more info.
+
+- Main repo now on usnistgov.
