The Quasar team now have their own upgrade notes as well.
Some simple notes of changes I found during migration from v0.17 to v1.0-beta. I used a fresh app directory created using quasar create <folder> -b dev and copied my components/routes/etc to the new folder.
For the most part all folders are the same except for src/plugins. This folder has been renamed to src/boot. They currently function in the same way as before however boot plugins can now by asyncronous.
