Mattermost moving to API version 4

[jasonblais]

Hey @CGenie !

First, hugely appreciate you sharing this project back with the world. Fantastic work!

I wanted to let you know about our plans moving to API v4:

To make the Mattermost API web service easier to use and to offer more powerful options for these integrations, Mattermost will be moving to a new API version soon. Highlights include:

• Fully documented API endpoints
• More in-depth access to server functionality
• Wider use of established HTTP verbs
• Consistent endpoint structures
• A new and improved Go driver

We plan to release API version 4 on March 16th, with Mattermost server 3.7. While the current API version 3 will be supported until September 16th, we recommend you begin using API version 4 soon after its release.

Contributing

API version 4 is an active and on-going project. If you're interested in helping contribute, please join our Mattermost community instance and the APIv4 channel.

We've prepared a contribution process for APIv4 and a progress tracker for new APIv4 enpoints to help you get started.

We're also open for suggestions on adding new API endpoints to help with your integration.
