It isn’t possible to access the old site, but the content isn’t missing. It’s here[1]. There are links that point to old version generated content which isn’t on the new one. There’s an issue open for it[2].
I’ve generated a lot of links to whichever version of that document Google found at the time on the forums, so there will be a lot of broken links from the forums.
You can now create links to “/latest_api’” instead of “/Asterisk_XX_Documentation” and it’ll autoimatically follow the latest release. That’s what I’ll be converting all the broken links on the new docs site to.
Correct. It only applies to the dynamic documentation under “Asterisk XX Documentation/API Documentation”. We’ll be working our way through the user content shortly.
Another page that I rely on a lot is Asterisk Versions - Asterisk Project - Asterisk Project Wiki for which I’m now having to use the Wayback Machine. There wasn’t any obvious in the new index, and Google hasn’t yet found the replacement with enough page rank to be able to find it.
