  sends the 220 response or otherwise is dead slow, libcurl will not
  acknowledge the connection timeout during that phase but only the "real"
  timeout - which may surprise users as it is probably considered to be the
  connect phase to most people. Brought up (and is being misunderstood) in:
  http://curl.haxx.se/bug/view.cgi?id=2844077

  read stdin in a non-blocking fashion. This also brings back -T- (minus) to
  the previous blocking behavior since it could break stuff for people at
  times.

  Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
  Fix data corruption issue with re-connected transfers
  Fix use after free if we're completed but easy_conn not NULL

5.4 Rearrange request header order

Things to play with when you're bored

than what's absolutely necessary:

curl will do its best to use what you pass to it as a URL. It is not trying to
validate it as a syntactically correct URL by any means but is instead
VERY liberal with what it accepts.

bugs we know about that will appear in the next release (too)

  something beyond ascii but currently libcurl will only pass in the verbatim
  string the app provides. There are several browsers that already do this
  encoding. The key seems to be the updated draft to RFC2231:
  http://tools.ietf.org/html/draft-reschke-rfc2231-in-http-02

  They introduce known_host support for SSH keys to libcurl. See docs for
  details.

  http://curl.haxx.se/bug/view.cgi?id=2818950

  errno is not reset on success.

updated openssl version to latest; removed obsolete link to openssl patch since its now in the openssl releases.

renamed generated config.h to curl_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.

  range if given colon-separated after the host name/address part. Like
  "192.168.0.1:2000-10000"

pointed out!

With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:

CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)

DEBUGBUILD used for debug enabled specific code (--enable-debug)
