If you have been using #bitly/621 and have cookies larger than the 4kb limit, the cookie splitting pattern has changed and now uses _ in place of - when indexing cookies. This will force users to reauthenticate the first time they use v3.1.0.
Streamed responses will now be flushed every 1 second by default. Previously streamed responses were flushed only when the buffer was full. To retain the old behaviour set --flush-interval=0. See #23 for further details.
