Version history for Sigil (Mac 64-bit)

<<Back to software description

Changes for v1.2.0 - v1.3.0

• Sigil-1.3.0 represents a mix of bug fixes and new features for both epub2 and epub3 users.
• Windows users please note that the installer will now allow Sigil to be installed for the current user only if desired. The installation of the included Visual Studio C++ runtime, however, will always require administrative privileges. You can provide those credentials for the runtime install portion only (if you install Sigil for the current user). The user can also skip the runtime check/install entirely if they desire. If they do so, however, it will be up to them (or their administrator) to make sure the proper Visual Studio C++ runtime is installed. Because of these changes, it recommended that Windows users uninstall the previous version of Sigil before installing this one. No settings, preferences, or plugins (or their configurations) will be lost by doing so.

Changes for v0.9.18 - v1.0.0a

• Sigil-1.0.0 represents a major milestone in Sigil's history. The requirement that all epubs must be restructured to meet Sigil's long-held standard has finally been lifted. 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. Please read the following notes carefully to avoid confusion.
• The major changes since Sigil-0.9.18 include the following:
• Upon initial load, the epub structure that exists will be loaded and kept in its "as-is" state, moving and renaming nothing
• 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.
• 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. In either case, the BookBrowser tooltips will always show the file's true book folder relative path. 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.
• A Tools menu item has been added to standardize any epub already loaded to Sigil's old structure
• A Tools menu item has been added to allow a user to design a custom "empty" epub layout
• A "Move" context menu item has been added to BookBrowser to enable moving of resources to where you want them to be.
• A "Rename" context menu item has been added to BookBrowser to enable renaming of the NCX and OPF resources.
• 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.
• 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 new Preference setting defaults to showing only the filename as before, and the default empty epub for creating new epubs is the same as before. The interface and functionality should stay almost exactly the same. Loading any epub previously saved by Sigil will still work exactly as before. Only editing new epubs that are in non-standard form will necessitate a use of the new Tool menu (see the fourth item above) to standardize it.

---

Changes for v0.9.18 - v0.9.991 (1.0 Pre-release)

• Before Sigil 1.0 can be released, we felt it was very important to remove the restriction that all epubs must be in Sigil standard form which included one OEBPS folder, specific names for the OPF, and NCX, only one folder for each type of resource (Text, Images, etc.).
• Therefore, over the last two months, we have had to tear out much of the internals of Sigil to teach it to not standardize epubs on initial load, not to rename the OPF, NCX, not to move files to our specific folders, etc. Then we had to teach Sigil how to properly work with files in any structure or locations, how to build the correct links between them. This included extending the Sigil plugin interface appropriately.
• To accomplish this over 4000 lines of code were added and over 2000 were deleted, touching almost every file in Sigil. All of this work has been very disruptive with the potential for lots of breakage and new bugs being introduced.
• Special thanks must be given to both BeckyEbook and Doitsu for regularly building and testing the changes as they were being made and reporting back any breakage or issues they found and providing feedback on ideas. Without their hard volunteer effort, Sigil would be in a much much worse condition.
• The work on Sigil-1.0 has now stabilized, and it is now ready for additional volunteers and testers to try and break it so that any final nits or issues can be tracked down and fixed before the upcoming Sigil 1.0 release.
• The main changes include the following:
• Upon initial load, the epub structure that exists will be loaded and kept in its "as-is" state, moving and renaming nothing
• 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.
• 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. In either case, the BookBrowser tooltips will always show the file's true book folder relative path. 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.
• A Tools menu item has been added to standardize any epub already loaded to Sigil's old structure
• A Tools menu item has been added to allow a user to design a custom "empty" epub layout
• A "Move" context menu item has been added to BookBrowser to enable moving of resources to where you want them to be.
• A "Rename" context menu item has been added to BookBrowser to enable renaming of the NCX and OPF resources.
• 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.
• Additional bug fixes include:
• handle javascript location.href style in Preview
• use CaseInsensitive sort in Plugins menu (Thank you BeckDTP)
• use Locale aware sort routines for AddMetadata, and MetaData Names (Thankyou Doitsu)
• recognize x-font-otf style media types

Changes for v0.8.7 - v0.8.900

• - Removed Tidy and replaced it with a combination of a specially modified Gumbo

• - Removed Xerces, XercesExtras, Boost, and unused bundles.
• - Updated the source code to be compatible with the latest clang compiler by replacing all
• "undefined - behaviour" use of "Null" References with proper pointers across entire codebase
• - Completely revamped the build process to embed the Python 3.4 Interpreter
• inside of Sigil and integrate it in, including as site-packages:
• [lxml, bs4, PIL, regex, six, html5lib]. This will allow plugins
• that use the internal Python 3.X engine access to all of these
• specialized packages by default with no additional action
• needed by end users of their plugin.
• - Created our own version of BeautifulSoup4-4.4.0 called sigil_bs4 that
• fixes lxml namespace bugs, fixes serialization/prettyprinting of
• inline xhtml tags, and modifies the bs4 codebase so that a single
• source code works equally well on both Python 2.7 and Python 3.X
• - Replaced internal opf and ncx xml processing and cleaning with a
• combination of embedded Python 3.4, sigil_bs4 / lxml
• - We now build Hunspell as a shared library and added a ctypes interface to allow
• plugins to spellcheck
• - We now build our modified gumbo html5 parser as a shared library
• and provide a bs4 ctypes interface to it for easy xhtml processing
• in plugins that use either Python 2.7 or Python 3.X
• - Allowed plugins to auto-fix "text/html" media-types to "application/xhtml+xml"
• - Began the transition to allow for both epub2 and epub3 editing
• (Note: epub3 editing is still incomplete)
• - Converted Flightcrew to become a Sigil plugin and replace it with
• a simple and fast internal sanity checker.
• - Updated Hunspell dictionaries to be actual dictionaries and not just word lists for en_US and en_GB
• - Updated other dictionaries to their most current version to match what is used in LibreOffice 5
• - Fix issue #54 modified date using local numerials when it should be
• using Arabic numerals per the spec.
• - Set the book to modified when font's are obfuscated.
• - Change FORCE_BUNDLED_COPIES build flag to USE_SYSTEM_LIBS. This flips
• the meaning of the flag. Now USE_SYSTEM_LIBS will enable using system
• libraries. Also, SYSTEM_LIBS_REQUIRED was added which will fail the
• cmake configure if any system libraries are not found instead of
• falling back to the bundled copy. Finally, this makes the build more
• consistent for Windows and OS X users.
