 ### Added
 
-- Add `--disable-env-management-py` and `--disable-env-management-r` flags for all content types that support environment restores (non static).
-  This flag indicates to Connect that the user is responsible for Python/R package installation and Connect should not install
-  packages during the build.  The Python/R packages must still be available in the runtime environment in order to run the content.
-  This is especially useful if off-host execution is enabled when the execution environment (specified by `--image`) already contains the required
-  packages. Requires Posit Connect `>=2023.07.0`.
