The major changes in this version of the draft are to expand discussion
of IP multicast, protocol-specific endpoints, and security; clarify use
of domain names when creating endpoints and how to represent endpoints
with multiple IP addresses; better explain the role and use of the
Preconnection; consistently use
RFC 2119 language
for normative requirements; clarify types and terminology; and to
improve consistency of presentation. There are also numerous minor
editorial fixes throughout.

This version clarifies that the specification is not prescriptive on
the form of the implementation; clarifies behaviour when handling of
errors setting properties; clarifies that as application MUST NOT
assume that it can receive any further data on a Connection for which
it has called Close; removes the zeroRttMsgMaxLen parameter, which was
determined not to be useful; and updates the text to use consistent
capitalisation for message types, etc.

clarifications and additional examples relating to multicast;
additional discussion of Constraining Interfaces for Endpoints;
clarifications around the set of local endpoints returned when
resolving a Preconnection;

and protocol-specific properties;
and expanding the examples around partial receives.

This version updates the Abstract and Introduction to more clearly
state the benefits of the Transport Services framework, and updates
the API summary to more clearly show use of the API.
It expands the discussion of the use and role of Preconnection
objects, preferences, provisioning domains, connection groups, and
connection termination.
And it explains how to disable security in the Transport Services API,
when talking with legacy endpoints such as TCP servers that don't use
TLS, while noting that this use is not recommended.

This is a minor updates that makes some clarifications around transport
properties and multipath transport, adds a Connection.CloseGroup()
action, and updates the state diagram to include the closing state.

This version of the Transport Services API draft adds some discussion
of advertising alternative addresses for multipath connections, and of
connections where the initiating side is not the first to write. It
better explains the model for connection property negotiation, and adds
properties to signal multi-path transports and bounds on send and
receive rate. It also includes a large number of minor updates,
clarifications, and fixes throughout.

-
This version version is a major update. It updates the introductory
remarks; clarifies that some events might have default handlers in
certain implementations, and that it's not necessarily safe ignore
events; expands the examples; expands discussion of transport properties
and other parameters; adds discussion of multicast; clarifies the
relation between Initiate() and Preconnection
objects; clarifies the behaviour of passive listen and peer-to-peer
rendezvous; clarifies and role and behaviour of cloned connections and
connection groups; clarifies the role of framers; expands discussion of
Message Contexts; clarifies that maxLength and
minIncompleteLength are used to manage buffering and are
unrelated to message ordering; updates protocol-specific properties;
and expands the security considerations.

This draft was adopted as a work item of the TAPS working group at IETF
101 in London in March 2018. In addition to a number of editorial fixes,
the draft removes the ability to clone Preconnections;
expands discussion of property negotiation;
removes immediate acknowledgement and adds batching sends;
and clarifies the response to ICMP soft errors.
This draft replaces
