Please note, the design goal of Sigil 1.0.0 was to make minimal changes for users and ebook developers that still want to use Sigil as they did.

The python plugin interface has been extended to support all of this as documented in the new Sigil_Plugin_Framework_rev12.epub and online at MobileRead in our Plugin Development thread.

A “Rename” context menu item has been added to BookBrowser to enable renaming of the NCX and OPF resources.

A “Move” context menu item has been added to BookBrowser to enable moving of resources to where you want them to be.

A Tools menu item has been added to allow a user to design a custom “empty” epub layout.

A Tools menu item has been added to standardize any epub already loaded to Sigil’s old structure.

Duplicate file names (in different subfolders) will always show the longer path to be able to differentiate between them regardless of the new Appearance Preference. In either case, the BookBrowser tooltips will always show the file’s true book folder relative path.

A new Preferences setting has been added to the Appearance Preferences that will determine if the book folder relative path will be shown in the BookBrowser or its shorter unique name (filename) will be used instead.

The BookBrowser will still show the Text, Images, Styles, Fonts, Audio, Video, and Misc “folders” but these are now “virtual folders” that simply organize the existing resources by type but do not restrict their actual location within the epub.

Upon initial load, the epub structure that exists will be loaded and kept in its “as-is” state, moving and renaming nothing.

The major changes since Sigil-0.9.18 include the following:

Please read the following notes carefully to avoid confusion. Users can still manually choose to restructure epubs to the old Sigil standards if they choose, but it will no longer be done automatically upon opening. The requirement that all epubs must be restructured to meet Sigil’s long-held standard has finally been lifted. Sigil-1.0.0 represents a major milestone in Sigil’s history.
