http://curl.haxx.se/mail/lib-2007-06/0238.html, libcurl didn't properly do
no-body requests on FTP files on re-used connections properly, or at least
it didn't provide the info back in the header callback properly in the
subsequent requests.

tool reports and it was indeed a legitimate one and it is one fixed. It was
a use of a share without doing the proper locking first.

(http://curl.haxx.se/bug/view.cgi?id=1740263). Adam discovered that when
getting a large amount of URLs with curl, they were fetched slower and
slower... which turned out to be because the --libcurl data collecting which
wrongly always was enabled, but no longer is...

(http://curl.haxx.se/bug/view.cgi?id=1739100) that mentioned that libcurl
could not actually list the contents of the root directory of a given FTP
server if the login directory isn't root. I fixed the problem and added three
test cases (one is disabled for now since I identified KNOWN_BUGS #44, we
cannot use --ftp-method nocwd and list ftp directories).

HTTP CONNECT over a proxy

CURLOPT_FTP_CREATE_MISSING_DIRS works for SFTP connections as well as FTP
ones.

(http://curl.haxx.se/bug/view.cgi?id=1733119) and we collaborated on the fix.
The problem is that for 64bit HPUX builds, several socket-related functions
would still assume int (32 bit) arguments and not socklen_t (64 bit) ones.

- -s/--silent can now be used to toggle off the silence again if used a second
  time.

- Added Daniel Black's work that adds the first few SOCKS test cases. I also
  fixed two minor SOCKS problems to make the test cases run fine.

to find that it crashed miserably, and this was due to some select()isms left
in the code. This was due to API restrictions in c-ares 1.3.x, but with the
upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much
better with c-ares and the multi interface with > 1024 file descriptors in
use.

overwrite in Curl_select(). While fixing it, I also improved its performance
somewhat by changing calloc to malloc and breaking out of a loop earlier
(when possible).

Black identifying several FTP-SSL test cases fail when we build libcurl with
NSS for TLS/SSL. Listed as #42 in KNOWN_BUGS.

for libcurls with CURL_DOES_CONVERSIONS enabled that fail to convert the CN

bug report #1715394 (http://curl.haxx.se/bug/view.cgi?id=1715394), and the
transfer-related info "variables" were indeed overwritten with zeroes wrongly
and have now been adjusted. The upload size still isn't accurate.

Allow SFTP quote commands chmod, chown, chgrp to set a value of 0.

sftp didn't truncate it first, which would corrupt the file if the new
file was shorter than the old.

when CURLOPT_HTTP200ALIASES is used to avoid the problem mentioned below is
not very nice if the client wants to be able to use _either_ a HTTP 1.1
server or one within the aliases list... so starting now, libcurl will
simply consider 200-alias matches the to be HTTP 1.0 compliant.

libcurls, which turned out to be the 25-nov-2006 change which treats HTTP
responses without Content-Length or chunked encoding as without bodies. We
now added the conditional that the above mentioned response is only without
body if the response is HTTP 1.1.

been removed from a multi handle, and then fixed another flaw that prevented
curl_easy_duphandle() to work even after the first fix - the handle was
still marked as using the multi interface.

was 16385 bytes (16K+1) and it turned out we didn't properly always "suck
out" all data from libssh2. The effect being that libcurl would hang on the
socket waiting for data when libssh2 had in fact already read it all...

the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection

curl_easy_perform(). It would then wrongly free range-related data in the
connection close funtion.

  function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the

  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().
