• BREAKING: Fixed an issue in which UploadRequests were not getting headers added via the RequestChainNetworkTransport's additionalHeaders. Please note that if you've subclassed the RCNT, you'll need to update your overrides since we had to add a parameter. (#1644)
• Stopped GET requests from sending a Content-Type header, which could cause servers not configured to ignore that header when the body is empty to freak out. (#1649)
