Without a timeline it's impossible to continue doing business with your extensions.
PHP7 is now the standard, and it's impossible to build a new website with a previous version of PHP (otherwise I should redo all sites to my customers for free once the update comes out).
At least provide us an approximate timing (1/2/3/etc. weeks, 1/2/3/etc. months, 1/2/etc. years).
Before you say that everything was ready for the end of the summer, then for the end of the year and now... it's worse than a tv series.
At this point I begin to think that there are problems in the development of DataBridge that cannot be overcome.
