I just pushed a 0.5.7 release. I've been working quite a bit to prepare version 0.6 (which will mainly enable updating rendered templates), rewriting things many times, and I decided to do another release before 0.6 because of some already useful changes.

On a user's perspective, here is what changed in this version:

• New directives are available. @dom enables inserting DOM nodes when rendering:

@dom someNode

template.render({ someNode: document.createElement("div"); });

• You can now create reusable "components" using @define and @use:

@define "article"
    .article
        h1 "{{ title }}"
        "{{ text }}"

@each articles
    @use "article"

• Rendering performance has been boosted quite a lot (around 30% faster in my not-scientific-at-all benchmarks). This is actually a quite welcome side effect of rewriting things to enable template updating.

For people defining directive helpers, here is a summary of what changed; please refer to the documentation for more details.

• Directive helper definition has changed a bit to prepare ground for 0.6; helpers defined before 0.5.7 are incompatible. The two main changes are that rendered nodes are now to be inserted into a document-fragment passed as a parameter, and that the outer and inner context objects are now both "real" parameters (no more using this).
• The pushEvalVar and popEvalVar methods on rendering context objects have been deprecated in favor of new pushScope and popScope. They will be removed in version 0.6.

More changes have happened under the hood, see the changelog for more details.
