I won't list everything but here are the most important improvements:
- The publishing process
- Templates & the architecture of views
- Primary views customizations (including use of the uicfg module)
- Hooks & Operations
- Proper usage of the ORM
- Unit tests
- URL rewrite
Last but not least, a whole new tutorial based on Sylvain's great series Building my photos Web site has been included. It covers some advanced topics such as Operations and sophisticated security settings.
The visual style has been enhanced a bit to have better readability.
As always, patches are welcome !
