Broken links to motoko base documentation

I used to access the motoko base libs at or, but that’s now a 404.

It seems that they are now at

Not sure when that changed, but may I kindly suggest to not break URLs so easily? They are in bookmarks, browser history and (worst) linked from documentation, possibly even in blackholed canisters.

If you have to change URLs, please leave redirects in place.


Also, it it kept up to day? Internet Computer Content Validation Bootstrap misses subArray, included sinceversion 0.8.4. Maybe the page should include a version annotation.

Right now, we try to have the Motoko documentation in sync with the latest version bundled with dfx. I’ll see what I can do to make it more clear

I added IIRC but it would be great if every page had some version indicator.
