At the end of the The Great Asterisk Migration of 2023 blog posting there is this:
Oh, if you’re wondering what happened to all the old issues from https://issues.asterisk.org, they could not be converted and are still there. We’re looking at ways to create a searchable archive of the issues for long term reference.
Has that ever materialized?
As an aside, this sort of switching of tools/deprecation/loss of information/history is exactly why I continue to resist various organizations coercive attempts at “paperless billing”, or “online statements”, etc. They are only “online” or otherwise available at the pleasure of the company providing them.
On the other hand, the paper copy that I insist (for as long as I possibly can) that they send me in the mail is in my filing cabinet and will always be there and available for as long as I want it to be.
