redux-form/redux-form v6.0.0-rc.5 on GitHub

Updated exported propTypes. #1447
Fixed a bug with array splicing. #1492 #1490 Thanks, @clayne11!
Fixed a bug with field unregistering. #1486 #1460
Fixed a bug with reinitializing on remounting. #1556 #1503
Allowed sync validation to set a form wide _error like async and submit validation could. #1560 #1533 #1328
Fixed a bug where fields would not amend their registration when their name prop changed. #1561 #1528

Added a keepDirtyOnReinitialize config parameter that will allow the initialValues to change without overwriting dirty fields. This is useful if you are continually saving the data as the user fills out the form. See #1465 for more details. Thanks, @hathawsh!
blurredField now passed to asyncValidate. #1539 #817 #980 #1511 Thanks, @KaboomFox!
Allowed fields to have a _error assigned to them. #1508 #1107 Thanks, @clayne11!
Fields now get a meta.submitting flag. #1509 #1122 Thanks, @clayne11!
Added a pure config parameter that can short circuit shouldComponentUpdate(). #1449 Thanks, @edvinerikson!
Added 🎉 Fields component 🎉 that allows you to connect to multiple fields at a time. This was the last major piece of functionality to allow you to do in v6 what you could do in v5. #1554

Why no release yet?

There is one other breaking change that I want to consider squeezing into v6.0.0.
