Changelog

Sourced from mustache's changelog.

[3.0.1] / 11 November 2018

• [Zoom in then out moves slide transition controls out of browser window hakimel/reveal.js#679]: Fix partials not rendering tokens when using custom tags, by @​stackchain.

[3.0.0] / 16 September 2018

We are very happy to announce a new major version of mustache.js. We want to be very careful not to break projects
out in the wild, and adhering to Semantic Versioning we have therefore cut this new major version.

The changes introduced will likely not require any actions for most using projects. The things to look out for that
might cause unexpected rendering results are described in the migration guide below.

A big shout out and thanks to [@​raymond-lam] for this release! Without his contributions with code and issue triaging,
this release would never have happened.

Major

• [Add editorconfig.org configuration file hakimel/reveal.js#618]: Allow rendering properties of primitive types that are not objects, by [@​raymond-lam].
• [Cancel hakimel/reveal.js#643]: Writer.prototype.parse to cache by tags in addition to template string, by [@​raymond-lam].
• [Add details to README on creating themes. hakimel/reveal.js#664]: Fix Writer.prototype.parse cache, by [@​seminaoki].

Minor

• [Provide workarounds for local files (offline mode) hakimel/reveal.js#673]: Add tags parameter to Mustache.render(), by [@​raymond-lam].

Migrating from mustache.js v2.x to v3.x

Rendering properties of primitive types

We have ensured properties of primitive types can be rendered at all times. That means Array.length, String.length
and similar. A corner case where this could cause unexpected output follows:

View:

{
  stooges: [
    { name: "Moe" },
    { name: "Larry" },
    { name: "Curly" }
  ]
}

Template:

{{#stooges}}
  {{name}}: {{name.length}} characters
{{/stooges}}

... (truncated)
