1.0.0 - 2026-08-13

Added

• First stable release of the pure-Dart Handlebars template engine.
• Variable substitution with dot and slash path access, parent context (../), and the this/. current-context reference.
• HTML escaping by default, with unescaped output via {{{ }}}, {{& }}, and SafeString.
• Built-in block helpers: if, unless, each, with, including {{else}} and inverse ({{^}}) sections.
• Iteration data variables @index, @key, @first, @last, @root, and block parameters (as |item index|).
• Custom helpers with positional and hash arguments, block helpers with fn and inverse callbacks, and subexpressions.
• Built-in lookup and log helpers.
• Partials, partial blocks ({{#> }}), and inline partials ({{#*inline}}).
• Comments ({{! }} and {{!-- --}}), literals, raw blocks ({{{{raw}}}}), whitespace control ({{~ ~}}), and the \{{ escape sequence.
• Strict mode that throws StrictModeException on undefined variables.

Changed

• The ANTLR4-based parser and its generated grammar are now test-only. The published library ships the hand-written parser exclusively and no longer depends on the antlr4 runtime.
