Jetpack now smartly supports development sites
Heck yes! Finally, Jetpack has really nice support for identifying development websites.
When Jetpack sees a URL change on your site, it prompts you to identify whether it’s a new site, if your domain changed, or if it’s a development / staging site.
This is a great win for developers.
Another nice nugget in 3.7 is a new rule for the “Widget Visibility” module. Anyone that’s done a decent amount of client work is familiar with conditional widgets to apply to only certain site sections. With Jetpack, you can now assign a widget to be conditional on a page and any sub-pages of that page, giving conditionality to the whole site section within a particular hierarchy.
