One of the biggest barriers to upgrading from Drupal 4.6 to Drupal  
4.7 will be upgrading contributed modules.  We have found that many  
administrators write simple modules for their site but have trouble  
porting them forward.  The page that instructs them how to do this  
has 19 comments since September.  It's clear that the page needs to  
be edited as the steps for upgrading to new hooks and using the Forms  
API has changed of the last several months.  However, this page needs  
serious technical review from the development community.

Delete comments that are no longer valid

Delete comments that are off topic from the page
Upgrade the documentation on the page if the comment is valid.

Cheers,
