### Breaking Changes

This version of FastAPI drops support for Python 3.6. 🔥 Please upgrade to a supported version of Python (3.7 or above), Python 3.6 reached the end-of-life a long time ago. 😅☠

* 🔧 Update package metadata, drop support for Python 3.6, move build internals from Flit to Hatch. PR [#5240](https://github.com/tiangolo/fastapi/pull/5240) by [@ofek](https://github.com/ofek).

Or you might have any other way to communicate with the WebSocket endpoint.

But for this example, we'll use a very simple HTML document with some JavaScript, all inside a long string.

This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.

When a **container** is started, it will run that command/program (although you can override it and make it run a different command/program).

A container is running as long as the **main process** (command or program) is running.

    val task =
      object : Task("task") {
        val schedules = mutableListOf(50.µs)
        val delays = mutableListOf(200.µs, -1)

        override fun runOnce(): Long {
          log += "run@${taskFaker.nanoTime}"
          if (schedules.isNotEmpty()) {
            redQueue.schedule(this, schedules.removeAt(0))
          }
          return delays.removeAt(0)
        }
      }
