OpenWrite 1.0 release notes

7 October 2026

OpenWrite 1.0 is the first public native-office release of the AmigaOS 3.2
editor and libowf document stack.

Highlights

  • native m68020 AmigaOS 3.2 editor; no FPU required;
  • DOCX and ODT open/save with common formatting, headers/footers, simple tables,
    hyperlinks and inline images;
  • ProWrite, Final Writer/Final Copy-family SWRT, Wordworth, IFF FTXT, ANSI and
    plain-text import;
  • character and paragraph formatting, styles, lists and page setup;
  • native simple table insertion and row/column editing;
  • embedded image insertion and datatype-backed display;
  • clipboard cut/copy/paste, find/replace and grouped undo/redo;
  • automatic pagination, page navigation, scrolling and zoom modes;
  • bundled en_GB spelling dictionary and persistent user dictionary;
  • recovery autosave after interrupted sessions;
  • searchable PDF export and standard printer.device output;
  • ARexx port for scripted document/open/save/export/print/text/search commands;
  • C:OWConvert for scripted conversion on any 68000.

Release validation

The 1.0 candidate passed:

  • native core/editor tests;
  • spelling tests;
  • core and spelling AddressSanitizer/UndefinedBehaviorSanitizer runs;
  • 3,206 corrupt/cut-short format cases under the normal and sanitizer gates;
  • m68k AmigaOS cross-build with zlib;
  • AmigaOS 3.2.3 + OpenRTG/OpenLook SpeedLab smoke using the release binary and
    a multi-page document, with no release-blocking alert/fault reported.

Release binary sizes at qualification:

  • OpenWrite: approximately 302 KiB;
  • OWConvert: approximately 162 KiB.

Known 1.0 boundaries

OpenWrite 1.0 intentionally does not claim full desktop-publishing layout.

  • simple tables are supported; merged/nested/advanced Office tables may be
    approximated;
  • images are inline; floating/wrapped images are post-1.0 work;
  • advanced section layout, multi-column sections, footnotes/endnotes and
    generated TOCs remain post-1.0;
  • Word 97-2003 .doc, RTF, Markdown and AmigaGuide import are not 1.0 filters;
  • tracked changes are accepted on DOCX import rather than edited as revision
    objects;
  • unsupported advanced Office objects are reported rather than silently
    claimed as editable;
  • printer.device output is the standard system print path; a fully unified
    graphics/WYSIWYG print-display pipeline remains later work;
  • grammar checking is not included.
