Grammar fix: easier use of dictionaries in assignment blocks, no conflict with embedding syntax.
...

Non-standard operator <> can be used as an alternative for != to avoid ambiguity with a verbatim block mark (!) inside if blocks.
Shortcut attributes .CLS and #ID no longer need spaces around, so div#main.left.top is now a correct tag occurrence.
The if-else operator returns "" (empty string) rather than None when the else branch is missing.
Grammar extended to support expression blocks ($ EXPR) without an assignment. Can be used for method calls, like in $myList.append(3).
Fixed html-escaping of special symbols inside HTML attribute values.
Built-in tag/function dedent accepts now an optional argument full.
Built-in tag/function inline renamed to merge.
New built-in tag and function, inline, converts all newline characters to HTML entities 
 for safe inclusion in indentation-sensitive blocks like <pre> or <textarea>.
New built-in functions: $crop(), alias $truncate().
New built-in tag, doctype, to produce a DOCTYPE declaration at the beginning of a page.
New built-in tag, custom "NAME" in HyperHTML runtime. It outputs non-standard HTML tag names, so that HTML Custom Elements (Web Components) can be used inside target documents.

Bug fix: exception raised in a "try" block caused "dedent" operations to be skipped, leading to incorrect calculation of indentations of subsequent blocks. Changed to always revert to an initial indentation when translating a body node.
Bug fix: post-translation state of an imported module included only output symbols. Changed to include all symbols (slots), since they can also be needed for hypertag expansion.

Syntax extended: loops may have an else clause.
Syntax extended: tags can be referenced inside expressions using the tag embedding operator %.

Added Django integration: a Hypertag backend (hypertag.django.backend.Hypertag) that can be plugged into a Django application.
Changed syntax for importing from dynamic context: added "context" blocks in place of "from ~ import ..." syntax.
Fixed and improved the import mechanism, classes: Runtime, Loader, Module.

Initial release.
