 You can directly reference pre-built versions of `Dockerfile` by using the `image` property in `.devcontainer/devcontainer.json` or updating the `FROM` statement in your own  `Dockerfile` to one of the following. An example `Dockerfile` is included in this repository.
 
 - `mcr.microsoft.com/devcontainers/go` (latest)
-- `mcr.microsoft.com/devcontainers/go:1` (or `1-bookworm`, `1-bullseye`, `1-buster` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/go:1.20` (or `1.20-bookworm`, `1.20-bullseye`, `1.20-buster` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/go:1.19` (or `1.19-bookworm`, `1.19-bullseye`, `1.19-buster` to pin to an OS version)
+- `mcr.microsoft.com/devcontainers/go:1` (or `1-bookworm`, `1-bullseye` to pin to an OS version)
+- `mcr.microsoft.com/devcontainers/go:1.21` (or `1.21-bookworm`, `1.21-bullseye` to pin to an OS version)
+- `mcr.microsoft.com/devcontainers/go:1.20` (or `1.20-bookworm`, `1.20-bullseye` to pin to an OS version)
 
 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/go:1-1.20` (or `1-1.20-bullseye`, `1-1.20-buster`)
-- `mcr.microsoft.com/devcontainers/go:1.0-1.20` (or `1.0-1.20-bullseye`, `1.0-1.20-buster`)
-- `mcr.microsoft.com/devcontainers/go:1.0.0-1.20` (or `1.0.0-1.20-bullseye`, `1.0.0-1.20-buster`)
+- `mcr.microsoft.com/devcontainers/go:1-1.21` (or `1-1.21-bookworm`, `1-1.21-bullseye`)
+- `mcr.microsoft.com/devcontainers/go:1.1-1.21` (or `1.1-1.21-bookworm`, `1.1-1.21-bullseye`)
+- `mcr.microsoft.com/devcontainers/go:1.1.0-1.21` (or `1.1.0-1.21-bookworm`, `1.1.0-1.21-bullseye`)
 
-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. `1-1.20`). 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.
