Sorry, the blog has hiccups with large traffic... Yes, this is a book on Delphi 5 I made available for free... but with hundreds of notes indicating what has changed and what is still relevant. A lot of content is applicable to Delphi 12.3, released this month!

Yes: "I've been creating a free to download edition of my classic "Mastering Delphi 5" with footnotes indicating what is different today"
