+### Removed

+- `rsconnect-python` no longer considers the `RETICULATE_PYTHON` environment variable.
+  In environments where `RETICULATE_PYTHON` is set outside a project context (e.g. by a Posit Workbench administrator),
+  attempting to deploy content or write manifests in projects using virtual environments required explicitly setting `--python /path/to/virtualenv/python`.
+  Removing `RETICULATE_PYTHON` detection should simplify the use of the CLI in this case.
