v4.1.0

This is a Draft release! Don't panic.

Breaking Changes

Several bugs were fixed that a user code might theoretically rely on, but most likely not:

• Config.getSources() no longer contains files read by parseFile outside of the load process
• when setModuleDefaults('modulename', ...) is called twice, the second call can overwrite values from the first
• Config.getSources() now agrees with setModuleDefaults, no matter how often it is called

What's Changed

Bugs fixed:

• #687 - you can now have deferConfig lines in submodules
• #822 - setModuleDefaults calls are now additive (slightly higher memory usage for defaults as a consequence)
• #827 - more accurate tracking of sources

v4.0.1

This release finalizes some work to extract 'util' functionality from lib/config.js into lib/util.js.

Breaking Changes

None known

What's Changed

• Finished extraction of util functions to lib/util.js
• Documentation of how to utilize this code for testing, or to drive setModuleDefaults()

v4.0.0

Breaking Changes
