There are a number of items in the TODO file that have been dealt with (to
some degree, anyway) and should really be updated or removed:

1.4 Get IP address
curl_easy_getinfo() now supports CURLINFO_PRIMARY_IP

1.5 c-ares ipv6
Doesn't curl now support this?

1.6 configure-based info in public headers
curlbuild.h is now a public header file. But a new issue should be added:
that of no longer being able to use a single header file for multiple
system variants (e.g. x86 vs x86_64).

2.2 Pause transfers
curl_easy_pause and CURL_READ/WRITEFUNC_PAUSE have been added

7.7 Provide callback for cert verification
Is this equivalent to CURLOPT_SSL_CTX_FUNCTION?

Also, is this issue:

5.1 Other HTTP versions with CONNECT

even relevant? What HTTP/1.1 features could one imagine using on CONNECT?
Do proxies even support any of them?
