For T163429: Provide UI for paging through Watchlist and Recent Changes results in the JS-enhanced UI, we will need backend support for paginating through RecentChanges / ChangesList. There already is a from parameter which might be able to be used for this, but it's only used by the "Show new changes since" link, and that might not allow us to page backwards. We will also need reverse sorting for the "sort by oldest first" feature in T162786: Integrate 'Number of Changes Selector' in the new filters for edit review, and the ability to specify both "from" and "to" timestamps for the date selector in T162784: Integrate 'Time Period Selector' into the new filters for edit review.
