I do recommend using rustup to all Rust developers now, despite still having reservations about its done-ness, and not being ready to commit to putting it on the main website (I guess that&#x27;s something of a contradiction).<p>This blog post marks the beginning of the phase where we will seriously try not to break things on upgrade - I consider it &#x27;in production&#x27; now.<p>Even now I think it provides the best installation experience and I have much higher confidence in its reliability than the older multirust shell script.<p>That said, if you are on Windows you might want to be more cautious. Just this week I broke rustup&#x27;s networking on Windows, and there are periodic reports of intermittent self update failures (though these don&#x27;t cause data corruption).
