.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.
ie, they can use arbitrary selectors on the server and in client stubs, but not
in other client contexts. This is to prevent clients from executing arbitrary
selectors against the DB.
Because of this, the update and remove allow/deny callbacks can only ever get
one doc, so switch them from getting an array to just getting the doc (like
insert).
