# Changelog

## 0.2.0 - 2026-09-02

- Added bounded, deterministic UTF-8 HTML/XHTML, Markdown and plain-text import
  adapters that create an explicit one-chapter EPUB workspace with loss
  evidence and no network resource fetching.
- Synchronized safe-reader backgrounds and text with explicit Toolbox light, dark, and system themes.
- Added visible, accessible phase and item-count progress while an EPUB opens and its first chapter is prepared.
- Resolved and validated both modern SVG `href` and legacy namespaced `xlink:href` image references, including standalone SVG title pages.
- Disabled namespaced SVG navigation links, reused object URLs for repeated images, and bounded unique/cumulative chapter image extraction.
- Added unit and cross-browser regression coverage for opening progress, dark reader contrast, SVG cover rendering, broken XLink resources, and repeated-image caching.
- Hardened standalone HTML export with a strict DOMPurify element/attribute
  allowlist so publication meta refreshes, base URLs, templates, frames and
  other active or network-capable structures cannot survive into the result.
