We’re excited to announce the first public release candidate of Meteor 1.2, which is now ready for early testing. We have some more QA to do, but we wanted to get it in your hands as soon as possible. You can upgrade your app using:
meteor update --release METEOR@1.2-rc.11
Meteor 1.2 is the biggest new release of Meteor ever! Highlights include:
- Faster application rebuild times, thanks to a new plugin architecture
- Cross-package LESS and Stylus imports
- Upgrades to Cordova mobile support
- Official support for React and Angular as view layer alternatives to Blaze
The biggest things to keep in mind with the upgrade process are:
Upgrading to a 1.2 RC will modify your .meteor/packages file. When switching back to a previous version of Meteor, you’ll need to revert this change in your source control.
Package authors: Packages that depend on Meteor 1.2’s versions of coffeescript, less, stylus, or templating, or that use the new ecmascript or static-html packages, will only work with Meteor 1.2 or later, which is enforced by the constraint solver. In addition, we had to bump the major versions of less and stylus in order to enable cross-package imports, so if your package contains LESS or Stylus files, you’ll have to re-publish using the 2.x versions of these packages to make your package 1.2-compatible (breaking compatibility with previous versions of Meteor).
See the Meteor 1.2 Upgrade Guide for more details. We will continue to revise the Upgrade Guide between now and final release.
Release-blocking bugs will be tracked in the Release 1.2 milestone.
Thanks everyone! Reply with feedback in the GitHub thread.
