• FIXED: The Turbo Streams Accept: header is only present for non-idempotent form submissions. [#52, #139]
• INTERNAL: Development builds have moved to the new hotwired/dev-builds repository shared with Stimulus.
• INTERNAL: The Location class has been replaced by the DOM URL API. [#90]
• INTERNAL: The page and frame rendering systems have been unified, and rendering is now asynchronous. [#133]
