    This change may increase OkHttp's memory use for applications that make many concurrent HTTP
    calls and that can receive data faster than they can process it. Previously, OkHttp limited
    HTTP/2 to 16 MiB of unacknowledged data per connection. With this fix there is a limit of 16 MiB
    of unacknowledged data per stream and no per-connection limit.

## Version 5.0.0-alpha.6

_2022-03-14_

 *  Fix: Don't attempt to close pooled connections. We saw occasional fast fallback calls crash in
    the previous alpha due to an unexpected race.


## Version 5.0.0-alpha.5

_2022-02-21_

 *  Fix: Don't include [Assertk][assertk] in OkHttp's production dependencies. This regression was
