Internal ChangesSection of the release
What
The internal channel/frame allocator that manages data transport (its allocate, transmit, and free operations) now supports:
an onRefused callback that can run per allocation
backpressure detection (isBackedUp) checked before resending data
tracking of orphaned sequences when an allocation is freed
a resend flag on transmit, instead of the previous model of always resending
Why
This makes the underlying transport more resilient: it can now detect when it's sending faster than the other side can handle (backpressure) and react to refused sends, rather than blindly resending every time.
