.meteor/packages in new apps now contains "standard-app-packages", which implies
the standard set of packages like mongo-livedata. There is no special-casing in
initFromAppDir. This line has been added to all the examples, etc.
There's a new concept of "upgraders". "meteor run-upgrader app-packages" will
add standard-app-packages to the app, as well as all of the package in the app's
packages/ directory (an unrelated change since 0.6.4). This will be integrated
soon with "meteor update"; run-upgrader is essentially for testing.
project.add_package no longer adds packages that are already there.
This package was always included in apps, and even if it was possible to remove,
there wasn't a compelling story about when users would remove and replace
it. Plus, not all backwards-compatibility code could even live in it (eg, field
names of objects), so it was incomplete. It also introduced odd load order
constraints.
Instead, we introduce two conventions for backwards-compatibility code:
- Special comments of the form "// XXX COMPAT WITH 0.6.4"
- When feasible, put backwards-compatibility code in a file called
"deprecated.js" in the relevant package.
This is documented at:
https://github.com/meteor/meteor/wiki/Meteor-Style-Guide#deprecated-code-and-backwards-compatibility
Additionally, removed some symbols that existed for backwards compatibility with
Meteor 0.4.0 (changes made 10 months ago): Meteor.is_client, Meteor.is_server,
and (in a method) this.is_simulation.
As part of the release process we'll update docs and all active
examples (other/unfinished examples can be updated as necessary). eg, first to
0.6.1-rc1, etc, and then to 0.6.1 when that is tagged from rc.
