4.0.1

• Read & use pre-upgrade state of the html, href, and model attributes.

Dropped support for content attribute

• content attribute is no longer supported, use href or html if needed #38

2.0.3

Compatibility fix for WCv0 and Polymer 1 to assign data model properly to <template is="dom-bind"> that is wrapped in Polymer 2 <dom-bind>. This allows using Polymer 1 in a way that is future compatible with Polymer 2 (#37)

Autonomous Custom Element v1

• migrated to Custom Elements v1 spec,
• made autonomous - due to lack of browser & polyfill support for "is attribute

Bug fix

It used to issue an /undefined request when the URL is set to undefined. Fixed in #34

Non-functional changes

Just a few updates for:

• README,
• package.json/bower.json,
• tests

Content tag split, property setters

• We split content attribute with heuristic detection of URLs vs. inline HTML, to more explicit separate attributes:
  • href for URL,
  • html for inline HTML content
• Thanks to above, we could now have property setters (reflected into the attributes) for those properties - Plays well with many data-binding systems.

Skip pending request when new content is set

Starting from now, once new content is set pending request (if any) will be skipped - no action will be taken once response comes.

Also, we will notify in console if empty file was fetched.

Clear content

Now, stamped nodes will get cleared after content attribute is removed/set to null.

1.0.1

Fix clear method to remove only those nodes, which are not yet removed.
