 You can directly reference [pre-built](https://containers.dev/implementors/reference/#prebuilding) versions of this image by using the `image` property in `.devcontainer/devcontainer.json` or updating the `FROM` statement in your own `Dockerfile` with one of the following:
 
 - `mcr.microsoft.com/devcontainers/python:3`    (latest)
-- `mcr.microsoft.com/devcontainers/python:3.9`  (or `3.9-trixie`, `3.9-bookworm`, `3.9-bullseye` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/python:3.10` (or `3.10-trixie`, `3.10-bookworm`, `3.10-bullseye` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/python:3.11` (or `3.11-trixie`, `3.11-bookworm`, `3.11-bullseye` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/python:3.12` (or `3.12-trixie`, `3.12-bookworm`, `3.12-bullseye` to pin to an OS version)
-- `mcr.microsoft.com/devcontainers/python:3.13` (or `3.13-trixie`, `3.13-bookworm`, `3.13-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/python:2-3.13` (or `2-3.13-bullseye`)
-- `mcr.microsoft.com/devcontainers/python:2.0-3.13` (or `2.0-3.13-bullseye`)
-- `mcr.microsoft.com/devcontainers/python:2.0.1-3.13` (or `2.0.1-3.13-bullseye`)
+- `mcr.microsoft.com/devcontainers/python:3-3.13` (or `3-3.14-trixie`)
+- `mcr.microsoft.com/devcontainers/python:3.0-3.13` (or `3.0-3.13-trixie`)
+- `mcr.microsoft.com/devcontainers/python:3.0.0-3.13` (or `3.0.0-3.13-trixie`)
 
 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. `2-3`). 
 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.
