Thanks for the submission @hahaschool! Can you merge main in - it needs the updates to set which test versions to run

Hi @TomDonoghue ,

Rebased, all tests passed locally.

Thanks.

Hey @hahaschool - sorry for the delay!

When returning a large number articles, you should really be using history (usehistory=True), as this stores the set of article IDs on the remote server, and then collects them in groups. This should in general avoid any issues with hitting URL limits, and is the general suggestion to collecting large numbers of articles.

That said, I think this still seems like a totally reasonable addition, and avoids any potential failures to collect a large number of articles when not using history. I did a quick check and direct refactor, but otherwise, I think we might as well add this - so I'm going to merge it in now!
