Thank you for your PR.
I found the ReceiveMessage __construct parameters so complicated. (#28)
And I am already started to refactor it.
Next release will change construct params.

@CasperLaiTW thanks for accepting the PR.

Do you have a roadmap document that we can share? I am actively developing an application using this library so it would be great to know what changes are upcoming.

[CasperLaiTW]

@obaid. First, thanks for you using the library on your project
I am sorry. The project is maintained on my free time, so I didn't plan any roadmap or schedule.
But next release do not update any getter function or interface, so do not worry about compatibility.

I check facebook messenger platform changelog, they are release new version.
Maybe I can plan some feature and create milestone on github.
Hope to help for you.

The v1.1 is almost done, maybe into plan v1.2

If you have any feature or enhancement idea, please create issue to me.
I will use my free time to implement.

[obaid]

I completely understand that. Perhaps, I will continue to add features / bug fixes as I go with my development effort and I will keep submitting PR requests to merge them in.
