The Ember.js Times - Issue #20
добры дзень Emberistas!

This week’s news: free ideas for your EmberConf talk, a heads-up that qunitjs has been renamed to qunit, a notification that Glimmer is asynchronously shiny, and an inspiring view into exactly how some patient, smart people have fixed some strange bugs.
EmberConf Call for Proposals - All you need to know from the CfP Brainstorming Session
On Thursday, the program committee hosted an online brainstorming session for the EmberConf 2018 CfP.  You can find the full audio recording of it on here, as well as the recordings from the two previous years. Committee members, core team members, and past speakers shared their perspective on audience questions, including: 
  • How to write a well-formed and detailed proposal
  • How to target a wide audience range 
  • Which topics might be interesting and engaging
  • and many more! 
The recipe for another great conference includes a variety of topics and levels of depth! If you have more questions, you can drop them in the #conf-emberconf channel on the Ember Community Slack. Remember to remove details that would get in the way of the CFP blind review. A warm thank you to @wifelette for organizing, publicizing, and facilitating, and to @wycats, @dgeb, @serenaf, @chancancode, @melsumner, @rwjblue, @jenweber, and many others for participating.
Listen to the Brainstorming Session
This week, efforts went into a beta bugfix for an issue around setting properties on a previously submitted, invalid model. Also, several assertions and warnings have been updated to use the respective, correct urls to the Guides for further info.

We’d like to thank @knownasilya, @raido, @pangratz and @sandstrom for either working on these improvements or reproducing bugs which were fixed this week.
Async Ember-Qunit Testing API Updates, Beta Bugfixes, Linting and more for Ember 🐹
Two new Ember-related RFCs have been created this week: First, an adaptation of the API for acceptance tests leaning to the new QUnit testing API has been proposed. You can read more about the changes here.
The second RFC aims to deprecate the {{link-to}} helper’s disabledWhen property in favor of disabled to unify its usage with that of other built-in components.
Two beta bugfixes landed, including a fix for the Array.replace method (you can read more on the quirky bug here) and for the extraction of route arguments in several Router service methods.
Apart from that, contributors to the Ember package applied the semicolon ES linter rule to the full repo, the accepted parameter types for the escapeExpression String util have been adapted, unneeded JSCS rules have been removed in favor of the already-adopted ESLinting, and more linter related updates landed (1, 2,3). Tests have been improved (1, 2, 3,4, 5,6) and another improvement prevents memory leaks stemming from the meta module.
Also, the qunitjs dependency has been migrated to its new nomenclature qunit in ember-qunit, the methods for setting up tests according to the new QUnit testing API are now async, and both the pauseTest and resumeTest helpers are available through this testing API.
Even more improvements landed here and there this week .For the Ember Inspector Plugin, a changelog update and another bug fix came in.

Many thanks to  @teddyzeenny, @lifeart, @bekzod,@Serabe, @Turbo87, @kellyselden, @krisselden and @rwjblue for working on all of these fixes and improvements.
The addon blueprint has been updated to make use of one of ember-try’s latest features - the useYarn flag to configure whether dependencies should be installed with npm or yarn during testing scenarios. Furthermore, a recursion issue has been fixed related to the detection of ember-cli-shims. Also, documentation about Ember CLI’s experiments has been created, cleanup work on leftovers from the earlier days of the web has been done, and the hamster emoji alias for ember has been removed. RIP. Finally, a few more support improvements and fixes, landed here, here and there.

Many thanks to @MiguelMadero, @Turbo87, @cibernox, @tristanpemble, @sangm, @sandstrom and @rwjblue for working on these features and fixes.
This week’s efforts around learning resources focused heavily on the Ember Guides; these included updates to code examples to reflect module imports according to the RFC#176 JavaScript Modules API (1, 2,3), and some other inconsistency fixes (1,2), as well as an illustration update

We appreciate the contributions of @staceyastewart, @woprandi, @williamhaley, @asizer, @SinghChandrabhan and @adamfeldman  for the learning resources this week.
Module & Template Locators, Test Updates and More Glimmer ✨
Work in Glimmer went into updating the way template metadata is passed in both eager and lazy compilation modes. You can read more about the characteristics of template metadata and the motivation of this PR in its detailed description and on another related PR here. Another change to the glimmer.js package makes use of this newly introduced system for looking up modules and templates to optimize bytecode compilation
Furthermore, the application’s boot method has been updated to be asynchronous, supporting async rendering paths and incremental rendering. 

Must go faster.”  -Dr. Ian Malcolm

Other updates included the @glimmer/test-helpers package being re-marked as private and removing it as a dependency from the glimmer.js package, moving tests for the {{#each}} helper to the VM, and increasing test coverage around data segment generation. Finally, several updates to the glimmer-blueprint package have landed this week, including linting the blueprints with TSLint, another change ensuring the blueprints are published consistently, and other updates (1, 2, 3,4).

We appreciate the work from @kellyselden, @chadhietala, @tomdale, @rwjblue and @t-sauer which went into improvements for Glimmer this week.
A bug for allowing the extension of the host application's FastBoot config from the fastbootConfigTree addon hook was fixed with an update to the way configurations are merged in. 
Also a linting error in ember-cli-fastboot has been fixed.

A thank you goes to @SergeAstapov and @kellyselden who worked on these improvements this week.
✨ That's a wrap up! See you again next week ✨

Be kind,
Jen Weber, Jessica Jordan and the Learning Team
Until the next issue, happy Embering :)
