[wp-hackers] Is there a plugin-writers guide that discusses security and other recent changes?

[David Chait]

With concepts like:
- the right way to do user access checks (preventing access to a 
particular plugin, or plugin's options, for example)
- when and how to use Nonces for admin panel security (for people like 
me with extensive custom plugin management pages, forms, etc...)
- how to best implement simple options (a few checkboxes) versus custom 
options (like my cg-amazon management interface, search, add, remove, etc.).

I need to update all my plugins, would like to make sure I'm hitting ALL 
the 2.0.x and 2.1.x enhancements to security (and any other 
functionality).  I've seen docs with some mention of what plugins need 
to do to support the newest WP releases (table name changes, global 
changes, etc.), but certainly not wide enough coverage of bringing 1.x 
plugins fully up to spec with say 2.1... ;)

Not to mention that I should change some of my plugins from storing 
on-disk to saving into the db options field (which will remove some 
headaches from install, I think...).

Thanks,
