Release Notes: This release adds agent-based authentication for SSH, allows applications to set sockopt after the accept() call with CURLSOCKTYPE_ACCEPT for FTP's active connection, adds a curl_multi_wait() function, lets metalink use the Microsoft Windows CryptoAPI, makes libcurl treat "socks://x" as a socks4 proxy, and lets the socks proxy handler support IPv6 connections through SOCKSv5 proxies. At least 37 bugs have been fixed.
Release Notes: This release fixes two security problems, adds CURLOPT_DNS_SERVERS and CURLOPT_ACCEPTTIMEOUT_MS, and fixes at least 54 documented bugs.

Release Notes: This release supports NTLM authentication when compiled with NSS. It has at least 37 documented bugfixes.
Release Notes: The --proto and -proto-redir options were added. The configure option --enable-threaded-resolver was added. PolarSSL, FTP wildcard matching, and RTMP are now supported.

Release Notes: Support was added for RTSP, IMAP, POP3, and SMTP and a few new options related to those. The PRET ftp command is now supported. The curl tool understands -J/--remote-header-name for using a server-provided filename with -O. Almost 30 bugs were fixed. One security related flaw was corrected.

Release Notes: The security problem denoted by CVE-2009-2417 was fixed. CURLOPT_SSH_KNOWNHOSTS, CURLOPT_SSH_KEYFUNCTION, and CURLOPT_SSH_KEYDATA were added, which makes libcurl support the openssh known_hosts files, and so does curl now. CURLOPT_FTPPORT (and curl's -P/--ftpport) was made to support port ranges. FTP quote operations are now optionally allowed to fail without causing a closed connection. Over 25 bugs were fixed.
