 Refer to [this guide](https://containers.dev/guide/dockerfile) for more details.
 
 You can decide how often you want updates by referencing a [semantic version](https://semver.org/) of each image. For example:
-- `mcr.microsoft.com/devcontainers/cpp:2-trixie`
-- `mcr.microsoft.com/devcontainers/cpp:2.1-trixie`
-- `mcr.microsoft.com/devcontainers/cpp:2.1.9-trixie`
-- `mcr.microsoft.com/devcontainers/cpp:2-bookworm`
-- `mcr.microsoft.com/devcontainers/cpp:2.1-bookworm`
-- `mcr.microsoft.com/devcontainers/cpp:2.1.9-bookworm`

+- `mcr.microsoft.com/devcontainers/cpp:3.0-bookworm`
+- `mcr.microsoft.com/devcontainers/cpp:3.0.0-bookworm`
 
 However, we only do security patching on the latest [non-breaking, in support](https://github.com/devcontainers/images/issues/90) versions of images (e.g. `0-debian-12`). You may want to run `apt-get update && apt-get upgrade` in your Dockerfile if you lock to a more specific version to at least pick up OS security updates.
