The speed of the crawling process has been increased. Proxy functionality, bandwidth limiting, and a man page have been added. The GUI look has been improved. The entire project has been converted to use pthreads. Several bugs related to memory leaks, handling of threads, the GUI, crawler, and GUI shutdown have been fixed.
Use of cURL with threads, rewriting the archiver to use MetaKit, tons of bugfixes, a new UIFace Class for a Windows GUI, fixes to the status information class, new per run features and nice kill handling, and bad or down host detection.
Lots of new features, including a text GUI with stats, better bandwidth limiting, host protection, a completely rewritten crawler class, and an order of magnitude increase in crawling capabilities. The new crawler displays your daily ranking, so you can see where stand in comparison to the other Grubsters.
