If you don&#x27;t skip versions, you get deprecation warnings for most changes before the breaking change in a subsequent version... jumping 3 versions was the bigger issue, second being that 3 versions in 1.5 years... but that is the JS ecosystem in general right now.<p>Beyond this, tfa is fighting with build tools that are a bit of a mismatch, which is a separate problem...  That it only took a day isn&#x27;t such a big deal really, and surprisingly good... it could have been integrated a couple of times over the course of that 1.5 years, instead of being left to rot.
