Version Switching

Starting with plugin version 2.9.34, Ninja Forms ships with both the 3.0 and 2.9.x codebases for backward compatibility. The deprecated 2.9.x codebase will ship with Ninja Forms for 1 years time to give users time to update custom code, etc.

With NF_DEV defined as TRUE (similar to WP_DEBUG), developers will gain access to a new admin bar menu for switching codebases.
