Release 2.4

[filipenevola]

As we have many big PRs right now in progress we are grouping them in this branch.

This branch was started from hot-module-replacement branch.

Beta

beta.3 is out. Our goal is to have beta.3 as our latest beta.

How to test 2.4

meteor add blaze-html-templates@1.2.0-beta.3

How to test 2.4 with HMR

You can try this integration in apps using Meteor 2 or newer by running:

meteor add hot-module-replacement blaze-html-templates@1.2.0-beta.3

To also use HMR for javascript files that use the Template api, run

meteor add blaze-hot

Hi @nathan-muir @brucejo75 @zodern could you help me with the https://github.com/meteor/blaze/blob/master/HISTORY.md updates for 2.4?

As we have many changes here would be important to highlight first important changes that could affect app behavior.

Thanks

submitted #325

[nathan-muir]

#319 Fixed a few situations where the template compiler wouldn't optimise it's output javascript.

Should make rendering faster (if the initial optimisation reasoning holds true)

#321 Just source code modernisation, making it easier to read. Shouldn't change any API's; except may need explicit import if other packages are using directly.

#324 Add a whitespace="strip" option to templates, which removes any whitespace that crosses newlines.

I added the hmr and the beta, actually get the following message in a constant interval:

@jankapunkt are you running Meteor 2 or newer?

cc @zodern

[zodern]

@jankapunkt you need to restart Meteor after adding the hot-module-replacement package so Meteor starts the HMR Server.

[jankapunkt]

@zodern thx that works, didn't read carefully enough and just added the packages via editing .meteor/packages besides that there are no issues found yet. However, I have another app where I intercept/override lots of Template.prototype functions so I will check this out as well.

[jankapunkt]

@filipenevola is there something left that needs to be done to move forward 2.4? Anywhere where we can help? The HMR is working really smooth so far, still no errors, even with my packages that hook deeply into the Templates.

There is nothing left. We are going to release in the next days. 💪
