Hi Juan,
it's becoming difficult to find documentation for all the new features in the new PI releases. 'Documentation' in the forums really won't scale because the posts contain links to other threads which makes it confusing. I have two suggestions:
1) create a single release notes page outside of the forum that grows upward (ie. add new releases at the top of the page). When a new release gets added, copy the release notes there. Make sure these release notes are fully inclusive, containing only links to images, not to text elsewhere. Links to forum threads are ok for context but shouldn't be like "read this to find out how to use this new process". Each new process/script and radical change should have a paragraph to describe the changes.
2) include the text for each process inside PI with the process. Assume you module 'Debayer-pxm.dll' then there should be a file 'debayer-pxm.htm' somewhere that can be opened with a simple action. The first version of the htm file can contain the text from the release notes.
Using this tactic you'll have optimum use of the text you're typing anyway and people will be able to find it more easily.
