Version 1.8.2.1 - the last Delphi 6 version was released 29th August 2002. The download contains source code only. See my Delphi site for the latest compiled version of XanaNews.
To compile the Delphi 6 version you'll need to install the XanaNews component package (included in the download), together with my Miscellaneous Units package (make sure you've got the latest version). You'll also need Mike Lischke's excellent Virtual Tree View component, Anders Melander's superb GIF Image component, Indy 9.03 , Mike Lischke's Theme Manager component, and Gustavo Daud's comprehensive PngImage component.
