Marco Cantù has published a new book, the Delphi 2007 Handbook. Unlike the previous books in the "Mastering Delphi" series, this book is more aimed to actual Delphi programmers needing a guidance to update their skill and applications to the latest release of Delphi and Windows operating systems. This book covers the "Win32 personality" of Delphi/Developer Studio only - no .net here :)
And unlike previous books, this one has been published using the "print-on-demand" service offered by lulu.com, following the path opened by Bucknall and Swart. You won't be able to find it at your local bookstore maybe, but IMHO that's the right way to write and sell more books about Delphi - and many more topics - hope we will see a new flow of good printed documentation - search engines and dreadful help systems are not useful to discover what you could do.
I am planning to install and test the new Developer Studio 2007 as soon as I will have some time to really test it before the trial run expires - fourteen days are not much when you're nearby a new release of your software.
