Event Timeline
Note that this is not entirely accurate due to the bug mentioned in T195546#10074921. In some lines, both parentheses contain the old namespace number, instead of the first one containing the old and the second one containing the new one. Unfortunately, I don’t think there’s any way to automatically find out the new namespace number other than querying them one by one, which is impractical.
However, you don’t need to know the namespace to access the page: you can use the curid index.php parameter instead, passing the very first number in the given line to it. For example, if the line you’re interested in is
angwiki: renaming 8321 (1,'Ƿicipǣdia:Ȝemǣnscipe_Ingang') to (1,'Ȝemǣnscipe_Ingang')
you can access the concerned page at https://ang.wikipedia.org/w/index.php?curid=8321 – MediaWiki will figure out what the correct namespace is.
