  -## What's changed
  +## Overview of what has changed
  +
  +Added:
   
   * [Plugins](/docs/agent/v3/plugins) for easily sharing functionality between pipelines and customizing how agents behave
  +* [Variable interpolation](cli_pipeline) in `pipeline.yml`
  +* [Build annotations](cli_annotate)
  +
  +Changed:
  +
  +* Agent meta-data has been renamed to "tags"
  +* Much better Windows support, including .BAT hooks support
  +* Checkout clean no longer ignores files in `.gitignore`
   * The bootstrap (run as a sub-process for every job) has moved from a [shell script](https://github.com/buildkite/agent/blob/2-6-stable/templates/bootstrap.sh) to [`buildkite-agent bootstrap`](cli_bootstrap). This means it's written in golang and cross-platform.
  -* Agent meta-data has been renamed to "tags"
  -* Built-in [Docker and Docker Compose support](/docs/builds/docker-containerized-builds) has been deprecated and moved to dedicated plugins, [docker-compose](https://github.com/buildkite-plugins/docker-compose-buildkite-plugin) and [docker](https://github.com/buildkite-plugins/docker-buildkite-plugin).

  +* Built-in [Docker and Docker Compose support](/docs/builds/docker-containerized-builds) has been deprecated. The same functionality is available from the dedicated plugins: [docker-compose](https://github.com/buildkite-plugins/docker-compose-buildkite-plugin) and [docker](https://github.com/buildkite-plugins/docker-buildkite-plugin).
   
   ## Bootstrap customizations
   
  -If you customized your `bootstrap.sh` file, you will need to move the changes to [hooks documentation](hooks), or update your bootstrap.sh to call `buildkite-agent bootstrap`.

   ## Docker and Docker Compose support
   
  
positive.code:       BUILDKITE_DOCKER: true
  ```
  
  There isn't a direct conversion for this at present, you can either add a docker-compose file and use the [docker-compose plugin](https://github.com/buildkite-plugins/docker-compose-buildkite-plugin), or if you want to run your build in a docker container without providing a `Dockerfile` or a `docker-compose` file, you can use the [docker plugin](https://github.com/buildkite-plugins/docker-buildkite-plugin):
  
  ```yaml
  steps:
  
negative.code:       BUILDKITE_DOCKER_COMPOSE_CONTAINER: app
  ```
  
  The same action with the [docker-compose plugin](https://github.com/buildkite-plugins/docker-compose-buildkite-plugin) looks like this:
  
  ```yaml
  steps:
