Depractions while upgrading ember-js to 1.12.0 and ember-cli to 0 0.2.5

Question

I am upgrading my Emberjs => from 1.10.0 to 1.12.0 Ember-cli => from 0.1.12 to 0.2.5

While i am figuring out most of the deprecations there are few which i am not able to understand. PFB the same

DEPRECATION: Ember.required is deprecated as its behavior is inconsistent and unreliable. Where is this used and how to change it?
DEPRECATION: lookupFactory was called on a Registry. The initializer API no longer receives a container, and you should use an instanceInitializer to look up objects from the container.
I do understand this issue but my initializer does not use lookup at all. PFB the code of my initializer.

//app/initializer/abc

initialize: function(registry, app) {
  app.register('store:main', Store);
  // Inject into each route a store property with an instance of store:main
  app.inject('route', 'store', 'store:main');
  // Inject into each controller a store property with an instance of store:main
  app.inject('controller', 'store', 'store:main');
}

//app/initializer/def

initialize: function(registry, app) {
        // Register the session object.
        app.register('session:main', Session);

        // Inject the session object into all controllers.
        app.inject('controller', 'session', 'session:main');
    }

DEPRECATION: Using the context switching form of {{each}} is deprecated. Please use the block param form ({{#each bar as |foo|}}) instead. See http://emberjs.com/guides/deprecations/#toc_more-consistent-handlebars-scope for more details.
I understand here that {{#each foo in bar itemController="abc"}} should be changed to {{#each bar itemController="abc" as |foo|}}. But my code is as below and does not have "in", meaning using this context!

{{#each paged itemController="class.adm.man.stop-term"}} How can i change this?

These deprecation notes doesn't always mean that it's your fault - troubles can be in any of ember addon which you use. For example, I got the note like your second one because of using of ember-simple-auth (see this issue ) — Tim Tonkonogov

Following your list:

Seems like it's an ember-data related issue. If not, I'm sure there is another addon which use it, but not you. Thus nothing you can do.
The same thing. I've already introduced an example as a comment. You code looks good for me, so, I believe, nothing you can do there as well.
Ember tries to make more consistent and explicit scopes. in part is not deprecated for now, so the simplest solution is to add dummy in part, for example {{#each page in paged itemController="class.adm.man.stop-term"}}. But in general I'd recommend to use more complex solution - to create an ItemList component and refactor it as:

{{#each paged as |page|}}
  {{item-list model=page}}
{{/each}}
