Thank you @mikemckiernan. This is a really great start!
| Invalid requests fail with a clear error. | ||
| - JIT-CDI mode now honors the `nvidia-container-runtime.modes.jit-cdi.nvcdi-disable-hooks` configuration option. | ||
| You can disable individual CDI hooks for environments where a generated hook is unnecessary or incompatible. | ||
| - The NRI plugin can inject ordinary workload CDI devices outside the toolkit namespace. |

I would move this bullet to under Enhancements to container-toolkit Container images as the NRI plugin is only used in that context.
| - Updating `config.toml` no longer reverts previously modified options to their defaults. | ||
| - CDI generation no longer adds an `update-ldcache` hook when it discovers no driver libraries. | ||
| This fix prevents containers from running an unnecessary hook and avoids failures on systems or modes that do not inject libraries. | ||
| - The toolkit installer now installs `nvidia-cdi-hook` instead of wrapping it with a shell script. |

I would move this bullet to under Enhancements to container-toolkit Container images as the toolkit installer (nvidia-ctk-installer) is invoked in the container-toolkit container.
| `update-application-profile`, and `update-ldcache`. The deprecated `chmod` hook | ||
| is disabled by default. Use `all` to disable every hook. | ||

| This release of the NVIDIA Container Toolkit `v1.20.0` is a feature release. | ||

| ### Fixes and Features |

One more fix to add to the list: NVIDIA/nvidia-container-toolkit#1969
| When CDI or JIT-CDI injects the GPU, the toolkit also limits EGL and Vulkan | ||
| visibility to the physical GPUs assigned to the container. For more information | ||
| and exceptional compatibility settings, refer to | ||
| [Graphics and OpenCL Workloads](cdi-support.md#graphics-and-opencl-workloads). |

Note that limiting EGL and Vulkan visibility is not unique to CDI/JIT-CDI modes. It is an existing behavior in legacy mode, and we recently updated CDI/JIT-CDI to bring feature parity across all use cases.
| ### Packaging Changes | ||
|
|
||
| - RPMs rebuilt by the toolkit packaging image now use XZ payload compression instead of zstd. | ||
| The resulting packages can be installed on Amazon Linux 2. |

The compatibility issue is not limited to Amazon Linux 2. AL2 is just an example of older Linux distros that do not support zstd compressed RPM packages. So I'd generalize to older Linux distros rather than limiting to AL2.
