Sigil 2.8.5 is a mixture of bugfixes and new features.

New Features

• remove outdated CSS parser and replace it with a modern spec-compliant Lexbor based css parser. See https://github.com/lexbor/lexbor. Note: Required upstream changes have been approved but are waiting to be merged until other changes requiring a major update are needed (ie size of parser and tokenizer structures needed to grow breaking the ABI). So do NOT replace our internal version of lexbor with a released lexbor version as it will currently not work. We will keep it internal with our own patches and statically linked to prevent dll issues until those requested changes are properly upstreamed.
• improve bulk addition speed of AddExisting/Drop Zone when replacing already existing images by directly using file write with truncation and thereby never touching the opf
• speed up Bookbrowser Refresh by bulk adding and removal items. (contributed by rinne1998)
• try to allow Sigil dock recent items on macOS platform
• allow multiple selection in the TOC Editor to speed larger changes.
• add image initial size to Sigil's Image tab.

• make svg cover images add href alongside xlink:href for Epub 3.4 spec changes
• make epub3 not add or use old epub2 cover metadata for Epub 3.4 spec changes
• allow epub3 Tools to control creation and removal of cover metadata to ease backwards compatibility

• add support for polyfilling jxl images in Preview using the URLSchemeHandler and jpeg format

• fix BookBrowser drag and drop errors with non-contiguous selections.

• detect malformed OPFs on initial epub load and warn user before auto repairing it
• fix bug in AdjustImage for handling gif Images that Qt can not write using python PIL to create them
• fix numerous user nits in the AdjustImage/Image Tab and make it safer for image types that are read only
• fix crash when adding a font and referencing it before its obfuscation type is set
• use QImageReader and QImageWriter supportedImageFormats to prevent AdjustImage bugs

Notes:

The Sigil Linux AppImage is built on Ubuntu Jammy (22.04) and is targeting glibc 2.35 and higher. Use ldd --version to see if your system at least has a shot at being able to use the AppImage. Don't forget to make sure the AppImage is executable after downloading. Trouble is not expected but be safe and backup your existing Sigil preferences (if you have any) before trying the AppImage.

The latest version of the Sigil User Guide can always be downloaded from the Sigil website, or from its own GitHub repository.
