You have probably read the announcement of the Wikimedia Developer Summit 2016 registration and call for participation.

https://www.mediawiki.org/wiki/Wikimedia_Developer_Summit_2016

I just want to stress that this year we are putting a special emphasis on inviting not only the developers of MediaWiki core, extensions, and APIs, but also the "other" developers using this platform to create gadgets, bots, templates, tools, apps, and third party products relying on Wikimedia APIs.

We want to increase their participation bringing their own proposals and joining others' as stakeholders, and we want to meet with them during the event in San Francisco. We have a modest sponsorship travel budget for those registering before OCTOBER 2nd (deadline for presentation of new proposals).

Reaching out to all these developers is not simple, as they are quite spread. Your help forwarding our invitation to the appropriate communities, mailing lists, Talk pages, etc, is very welcome.
