I’m planning to use develop an app targeting Meteor 1.2, is there a Meteor 1.2 early build available?
You can always use the current dev build from github:
Just follow the instructions at “slow start for developers”.
Is it possible that I can use two versions of Meteor at the same time? I have an another app developed in current stable version.
Using a Meteor binary that you’ve built from source (“slow start for developers”) doesn’t affect your regular, installed Meteor version. So you can have both in parallel.
a new core ecmascript package which uses Babel to let you write Meteor code in ES2015 (similar to grigio:babel)
Try it out with
meteor --release PLUGINS-PREVIEW@2.
