This release is largely a number of small bug fixes and improvements, along with a default change in behavior, which is technically a breaking change.
Breaking Change
We added an always_send option, enabled by default, which makes Flask-CORS inject headers even if the request did not have an 'Origin' header. Because this makes debugging far easier, and has very little downside, it has also been set as the default, making it technically a breaking change. If this actually broke something for you, please let me know, and I'll help you work around it. (#156) c7a1ecd
