[0.16.1] - 2026-07-26

TypeDoc documentation generation (npm run docs).
AGENTS.md with project conventions and development guidelines for AI agents.
use config option in render() for specifying an alternate element source (config, HTML markup, or existing Element).
untrack() function for non-reactive reads.
typecheck script for standalone type checking.

The effect() function is now debounced and simplifies subscription management.
Computed signal properties now use getter syntax (get) instead of callback functions.
render() signature has been simplified to accept a single config object; the HyperScript-style multi-argument syntax is removed.
classList option has been renamed to className for consistency with the DOM API; classList still works as a backwards-compatible alias.
The l10n() function has been renamed to i18n().
Rewritten to TypeScript (strict mode, TypeScript 6).
Build system migrated from Rollup to Vite (ESM + UMD).
Tests moved from tests/ to co-located src/**/*.test.ts files, run via tsx.
TypeScript declarations are now emitted to dist/ instead of a separate types/ directory.
Lifecycle events now dispatch directly on elements, no longer relying on MutationObserver.
README examples updated to reflect the new render() API.
Commit messages now follow the Conventional Commits specification.

Nested reactivity via the $ property prefix; use plain property names instead.
The mount() function; render() now accepts an optional second argument (target element, DocumentFragment, or CSS selector) and mounts automatically.
The changed lifecycle event; attribute changes from external sources are no longer observed.
The $$on(), $$once(), $$off(), and $$emit() helpers on signal proxies.
The tag property in element config; use tagName or use instead.
The ref callback in element config; use the mounted event handler instead.
Signal computed callbacks no longer receive (obj, prop) arguments; use this and getter syntax instead.
Internal helper modules context.js, emitter.js, and utils.js; functionality was inlined.
Legacy JavaScript source and test files.
Manually maintained types/*.d.ts declaration files.
