Sigil

Sigil is a free, open source, multi-platform ebook editor that uses Qt (and QtWebEngine). It is designed to edit books in ePub format (both ePub 2 and ePub 3).

For the impatient, the installer files (and source) can be found as assets at the bottom of the Sigil Github Release page.

Sigil-0.9.18 represents a mix of new features and bug fixes.

Bug Fixes:

• fix bug in macOS that caused spurious warnings about missing file in the manifest
• hopefully fix macOS bug about launching files using open-with from Desktop
• make sure JQuery gets loaded before starting to use Preview javascript functions
• fix local links during split that incorrectly used target filename for internal link
• create GetEnvironmentVar to make access to environment variables more cross-platform
• fix macOS bug when hitting close on the title bar of MainWindow causing strange window behaviour
• hopefully fix macOS segfault on close by disabling Preview timer immediately
• fix Windows 7 issues when running batch (.bat) files via OpenExternally (open with)
• all error messages are now properly logged
• fix improperly disabled open-with menu in Image Tabs popup context menu
• removed use of Qt obsolete methods in About and Error Dialogs

New Features

• enable use of SIGIL_DEBUG_LOGFILE environment var to control saving debug output to a file
• properly update the ncx after merging xhtml files
• properly warn users if a multiple rendition epub (multiple OPF files) has been loaded
• make Sigil’s external XHtml editor work to pass an OPF file (see PageEdit new features)
• Allow epub3 metadata editor to edit primary meta tags
• Replace buggy cssutils module used in plugins with our own drop-in replacement fork: css-parser
• Updated Mac, Windows, and Linux build documentation

Be aware that Sigil-0.9.18 no longer enforces the need for epub3 to have and support an NCX for the purposes of backward compatibility with epub2 reading systems. There are, however, built-in tools to allow users to add backward compatibility features such as the NCX to their epub3.
