Release Notes: Support was added for HTTP/1.1. Persistent connections are used with proxies which support them. The GNU TLS backend now works again and has been made default vs. OpenSSL. Now "--timestamping" and "--continue" work well together. By default, wget now uses the original URL to get the local filename on server redirects, to address the security vulnerability reported as CVE-2010-2252. Portability issues were fixed. Several other minor enhancements and bugfixes were made.
Release Notes: The license was changed to GPLv3+. Improvements were made to the HTTP password authentication code, bringing it a little closer to RFC compliance. Basic support was added for respecting filenames specified via "Content-Disposition" headers. An --ignore-case option was added to make wildcard- and suffix-matching case-insensitive. The --spider feature is working again (as it was broken in previous release). Many bugs were fixed.
Release Notes: Many bugfixes since the last public release. The ability to transmit data with the POST method has been added. IPv6 support is experimentally available (a more complete implementation is in the works). The option --timeout now also applies to DNS lookups. The progress bar has been improved to show download speed over a recent period, rather than over the average speed of the entire download. Connecting to FTP sites through FWTK firewalls should now work. It is possible to turn off DNS caching. Characters in file names are no longer aggressively %-escaped.
Release Notes: SSL support, HTTP keep-alive support, ability to accept, load, and store cookies, recognizing non-Unix directory listings (specifically VMS and Windows NT), and rewriting internal tables for speed when mirroring huge sites.
