As a developer, it is nearly impossible to access the site and page changelogs that were present in the previous wiki site.
If this issue gets resolved, it would help developers not only browse for new/updated APIs (that helped me discover the useful UTF-8 library), but it would also provide a layer of transparency that had been nonconsciously removed.
If you decide to reimplement global and page changelogs, please make sure they’re as functional as were the original.
