The proposed changes sent out earlier today implement the correct change for America/St_Johns but they leave America/Goose_Bay in a broken state from March 2011 onwards.
The America/Goose_Bay zone definition should look something like this:
# Zone NAME GMTOFF RULES FORMAT [UNTIL]

Subject: proposed time zone package changes (South Sudan, Samoa, Newfoundland...)
Proposed changes to the time zone package appear at the end of this message;
here's the executive summary:
africa Add Africa/Juba (South Sudan) zone.
australasia Samoa skips over 2011-12-30
(thanks to David Zuelke and Mark Sim-Smith).
europe Use KALT as abbreviation for Europe/Kalinigrad
from spring 2011 forward (thanks to Yoshito Umaoka).
northamerica Newfoundland changes time of day for DST start and end
to 2:00 a.m. starting fall 2011 and forward
(thanks to Michael Pelley).
Change America/Resolute use of EST to 2006-2007 only
(thanks to Chris Walton).
Assume Metlakatla abandoned use of daylight saving
as a result of its 1983 vote.
Avoid unnecessary use of US rule in
America/Honolulu; fix two typos in America/Honolulu
comments.
iso3166.tab Add SS (South Sudan) entry.
zone.tab Change America/Resolute entry to
Central Standard Time.
(thanks to Chris Walton).
Add SS (South Sudan, Africa/Juba) entry.
Providentially South Sudan's largest is also its capital city;
I hope there's no zone naming controversy.
I plan to update the ftp site on 2011-08-29 with these changes (modulo any
corrections provided by folks on the time zone mailing list).

# daylight saving....
# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html
! # From Chris Walton (2011-03-21):
! # Back in 2007 I initiated the creation of a new "zone file" for Resolute
! # Bay. Resolute Bay is a small community located about 900km north of
! # the Arctic Circle. The zone file was required because Resolute Bay had
! # decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
#
! # According to new information which I received last week, Resolute Bay
! # went back to using UTC-6 in the winter of 2007-2008...
! #
! # On March 11/2007 most of Canada went onto daylight saving. On March
! # 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
! # talked to somebody that was both knowledgeable and helpful. I was able
! # to confirm that Resolute Bay was still operating on UTC-5. It was
! # explained to me that Resolute Bay had been on the Eastern Time zone
! # (EST) in the winter, and was now back on the Central Time zone (CDT).
! # i.e. the time zone had changed twice in the last year but the clocks
! # had not moved. The residents had to know which time zone they were in
! # so they could follow the correct TV schedule...
! #
! # On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
! # phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
! # of the phone call, I decided to seek out an alternate source of
! # information. I found an e-mail address for somebody by the name of
! # Stephanie Adams whose job was listed as "Inns North Support Officer for
! # Arctic Co-operatives." I was under the impression that Stephanie lived
! # and worked in Resolute Bay...
! #
! # On March 14/2011 I phoned the hamlet office again. I was told that
! # Resolute Bay had been using Central Standard Time over the winter of
! # 2010-2011 and that the clocks had therefore been moved one hour ahead
! # on March 13/2011. The person I talked to was aware that Resolute Bay
! # had previously experimented with Eastern Standard Time but he could not
! # tell me when the practice had stopped.
! #
! # On March 17/2011 I searched the Web to find an e-mail address of
! # somebody that might be able to tell me exactly when Resolute Bay went
! # off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
! # used to be the mayor of Resolute Bay and he apparently owns half the
! # businesses including "South Camp Inn." This website has some info on
! # Aziz:
! # <a href="http://www.uphere.ca/node/493">
! # href="http://www.uphere.ca/node/493
! # </a>
! #
! # I sent Aziz an e-mail asking when Resolute Bay had stopped using
! # Eastern Standard Time.
! #
! # Aziz responded quickly with this: "hi, The time was not changed for the
! # 1 year only, the following year, the community went back to the old way
! # of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
! # the winter Zulu plus 6 hrs"
! #
! # This of course conflicted with everything I had ascertained in November 2008.
! #
! # I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
! # responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
! # may want to check with the weather office in Resolute Bay or do a
! # search on the weather through Env. Canada. web site"
! #
! # If I had realized the Stephanie did not live in Resolute Bay I would
! # never have contacted her. I now believe that all the information I
! # obtained in November 2008 should be ignored...
! # I apologize for reporting incorrect information in 2008.
