v1.28.0

What's Changed

Bring magic to a conversation with say_stream for streaming messages and show loading status with set_status. Now available for app.event and app.message listeners:

@app.event("app_mention")
def handle_mention(say_stream, set_status):
    set_status(
        status="Thinking...",
        loading_messages=["Waking up...", "Loading a witty response..."],
    )
    stream = say_stream(buffer_size=100)
    stream.append(markdown_text="Thinking... :thinking_face:\n\n")
    stream.append(markdown_text="Here is my response!")
    stream.stop()

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
