The IETF HyBi WG has moved beyond Last Call and has presented the WebSockets 
protocol to the IESG for approval:
 
        http://www.ietf.org/mail-archive/web/hybi/current/msg08640.html

Now that the protocol is more stable, I think that the current WebSockets API 
is feature complete and meets the requirements for publishing a Last Call 
working draft to encourage broader review and feedback.
 
Here is my review of the outstanding bugs (not closed, where resolution not 
Fixed). I recommend that the outstanding issues be resolved as Last Call 
comments and would like to see a CfC to publish a LCWD shortly.
 
9973 - If the entry's name is "sec-websocket-protocol" 0 please don't put 
normative requirements in parenthesis
Resolved, NeedsInfo
MICROSOFT PROPOSAL: Close the bug - This bug is a year old, likely out of date 
now, and from an anonymous contributor
 
12180 - give the name of url to download the Jetty server
Resolved, NeedsInfo
MICROSOFT PROPOSAL: Close the bug - This bug is from an anonymous contributor 
from 6 months ago. The API spec doesn't need to link to server implementations.
 
12510 - Specs split off from HTML5 (like WebSockets) need to have xrefs linked, 
otherwise they're ambiguous
Reopened, Assigned to Ian Hickson
MICROSOFT PROPOSAL: This is an editorial bug that should not block Last Call
 
13104 - 1) ping(msg); //allow client to send server ping as per websocket spec 
2) onpong();//allow client to receive response of ping
Resolved, NeedsInfo
MICROSOFT PROPOSAL: Close the bug - It's not necessary to include API support 
for ping/pong. In addition, this bug has been inactive for two months.
 
13172 - The definition for [MessageEvent] is missing
Resolved, NeedsInfo
MICROSOFT PROPOSAL: Close the bug - It's been inactive for a month and 
MessageEvent is defined in the HTML5 Web Messaging specification.
 
13700 - W3C SotD of this document still mentions whatwg.org version of the 
WebSocket protocol which is out of date.
New, Assigned to Ian Hickson
MICROSOFT PROPOSAL: This is an editorial bug that should not block Last Call
 
13777 - The WebSocket protocol draft (hybi-10) restricts the value of 
subprotocols as follows: The elements that comprise this value MUST be non- 
empty strings with characters in the range U+0021 to U+007E not including 
separator characters as defined
New, Assigned to Ian Hickson
MICROSOFT PROPOSAL: We'd like to see the spec updated as outlined in this bug.
 
13984 - Need a way to object detect which binary formats are supported before 
connecting
New, Assigned to Ian Hickson
MICROSOFT PROPOSAL: Close the bug. The original issue (binary support detection 
in Chrome) should be addressed in WebKit. The additional scenario (querying 
which binary types are supported) is not required in V1.
 
13990 - Need a spec for CloseEvent constructor
New, Assigned to Ian Hickson
MICROSOFT PROPOSAL: We'd like to see the spec updated as outlined in this bug.
 
14057 - In section "The WebSocket interface" when describing the operation of 
the WebSocket constructor, the following statement is made: "Return a new 
WebSocket object, and continue these steps in the background (without blocking 
scripts). ...
New, Assigned to Ian Hickson
MICROSOFT PROPOSAL: Resolve the bug as duplicate (12510) and close.
 
In addition, there is a new discussion on design changes for binary message 
support related to the original discussions in 12102 - WebSocket protocol 
update time:

MICROSOFT PROPOSAL: 

We do not support the proposed changes. Our implementation experience has not 
indicated this requirement. We find that most developers use blobs when there 
is a need to consume data as resources addressed by a URI or to store data in 
Indexed DB. We have haven't heard of a need to send a text message but then 
treat it as a blob. It also seems simple enough to convert text to blobs upon 
receipt?  

While limiting binaryType updates to onopen and onmessage appears to be more 
deterministic, it also implicitly suggests that network operations are then 
blocked on the completion of onopen or onmessage. For example, if the goal is 
to set the binaryType for the next message, then the next message cannot be 
received and the next onMessage event queued until the current onmessage 
completes. This may result in performance impacts on implementations that 
"pipeline" incoming messages.
