4.6.0

Added

• set_owner/2 now works while a response body is streaming, in both the synchronous and the async path. It used to return {error, invalid_state} once the body had started. This lets a short lived worker run a request and hand the still streaming response to a longer lived process before it exits, without stopping the connection.
• connect/4 accepts a binary host, restoring the 1.x behavior. A binary is converted to a string, so callers passing a binary host no longer fail.

Fixed

• A non-reusable connection (flagged no_reuse for proxy tunnels, SSL upgrades or a disabled pool, or answered with Connection: close) is now closed and its process stopped when a synchronous request completes, instead of parking in connected forever. With a long lived owner nothing stopped it, so one hackney_conn process leaked per request until the node ran out of memory (#902). The sync and async reuse decision now share the same check, which also stops a no_reuse pooled connection on the async path.
