Edits made while a save or autosave is in progress are no longer incorrectly marked as saved.
Older open, import, and history-restore requests can no longer replace the manuscript in a newly selected workspace.
Moving or converting parts and chapters now keeps navigation order aligned with EPUB reading order.
Improved keyboard access for chapter navigation and block controls.

Import and export

Fixed Markdown headings and path characters inside code fences from damaging manuscript structure.
Code blocks are now preserved in EPUB and DOCX exports.
Improved round-trip handling for EPUB chapter links, footnote anchors, images, and table widths.

Known issues

Beta

The beta candidate focuses on writing, saving, reopening, version recovery, importing, EPUB/DOCX export, and issue reporting.

Complex manuscripts may look different across EPUB readers and word processors, especially tables, image placement, and footnotes.
Older project files may reorganize their recovery-history storage the first time they are opened. Manuscript content should remain intact.

PDF export is not part of this beta candidate scope.
