I’m happy to announce the 103rd curl release: curl and libcurl 7.18.0.

No less than 35 persons beside myself contributed with info, reports and/or code to make the release as it turned out. We’ve added a bunch of new features and we’ve solved well over 30 different bugs. This is the news:

Changes:

• data-urlencode
• CURLOPT_PROXY_TRANSFER_MODE
• no-keepalive – now curl does connections with keep-alive enabled by default
• socks4a added (proxy type CURLPROXY_SOCKS4A for libcurl)
• socks5-hostname added (CURLPROXY_SOCKS5_HOSTNAME for libcurl)
• curl_easy_pause()
• CURLOPT_SEEKFUNCTION and CURLOPT_SEEKDATA
• keepalive-time
• curl help output was re-ordered

Bugfixes:

• curl-config –features and –protocols show the correct output when built with NSS, and also when SCP, SFTP and libz are not available
• free problem in the curl tool for users with empty home dir
• curl.h version 7.17.1 problem when building C++ apps with MSVC
