+List of changes in MuPDF 1.26
+
+	Removed PDF linearization support:
+
+		See https://artifex.com/blog/mupdf-removes-linearisation for
+		more information.
+
+	Object labels:
+
+		Write a comment before numbered objects listing the possible
+		ways it can be reached from the document root.
+
+		Enable with mutool show -L, mutool clean -L, and PDF write
+		option "labels".
+
+		Library functions pdf_load_object_labels and pdf_label_object.
+
+	Brotli compression:
+
+		Experimental feature from latest PDF specification proposal.
+
+	Optional barcode support:
+
+		Build with "make barcode=yes".
+		Uses zxing-cpp (zebra crossing) C++ as a third party dependency.
+		Adds mutool barcode sub-command.
+
+		To detect barcodes in a PDF:
+			mutool barcode -d barcode.pdf
+
+		To create barcode images as PNG file:
+			mutool barcode -c -o barcode.png -F qrcode "Hello, world!"
+
+		Library functions fz_new_barcode_image and
+		fz_decode_barcode_from_pixmap.
+
+	New Structured Text extraction passes:
+
+		Paragraph Breaking: Detect paragraphs from first-line
+		indentation and other heuristics.
+
+		Table Hunt: Scan text and try to assemble it into tables with
+		rows and columns.
+
+	New Structured Text extraction options:
+		- allow reading raw character or glyph index when unicode is not available
+		- collect styles to detect fake bold, underlines, strike-through, etc.
+		- clip-rect to only extract text inside the specified area
+		- accurate-ascenders to measure ascender data from font outline
+		- accurate-side-bearings to measure glyph widths from font outline
+
+	CSV output format (using "Table Hunt" pass on input document).
+
+	Core library additions:
+
+		JSON parser, object model, and printer.
+
+		Activity logger API.
+
+		Support "overlong null" characters in utf-8 (using "\xC0\x80"
+		to represent \x00 in C strings, without being misconstrued as a
+		string terminator).
+
+	Build system changes:
+
+		Cleaned up Makefile cruft and refactored how shared libraries
+		are built.
+
+		Removed bit-rotted sections of the Makefile that have not been
+		maintained and no longer work (primarily iOS and MinGW).
+
+		Don't build example tools muraster and mupdf-x11-curl by
+		default. These examples can be built with "make extra-apps".
+
+	Miscellaneous improvements and new behavior:
+
+		Include more data in structured text XML dumps.
+
+		Ignore junk at the start of a PDF file (such as PJL commands)
+		without needing to perform a full repair pass.
+
+		Support non-latin/greek/cyrillic/CJK languages in annotations
+		and widgets (requires HTML layout engine).
+
+		Use system font callback to look for missing fonts in HTML
+		layout.
+
+		Support CSS text fill and stroke properties:
+			-webkit-text-fill-color
+			-webkit-stroke-color
+			-webkit-stroke-width
+
+		Updated unicode line breaking (UAX 14) and upper/lowercase
+		tables to Unicode 16.0.

+
+		mutool show: new option -r (force repair)
+
+		mutool clean: --structure=keep to keep tagged content when
+		subsetting pages. WARNING: This option will prevent the file
+		from shrinking, because we must still keep all the objects from
+		deleted pages around.
+
+		mutool clean: -t option will always write compact objects
+		mutool clean: -tt option will always pretty-print objects
+
+	Useful new C functions and fields:

+		unreported errors will be automatically reported when a new
+		error is raised, or when closing the fitz context.
+
+
+	New formats:
+
+		Read Office (XML) files! We internally open and convert

+
+		fz_invert_bitmap to invert monochrome bitmaps.

+
+	Major bug fixes and improvements:
+
+		Support using Art, Bleed, Media, and Trim boxes for PDF page
+		size.
+
+		Support ActualText in PDF! No more strange text extraction when
+		the file uses ActualText to patch over bad font encodings.
+
+		Add special TrueType fallback encoding CMap for a specific
+		flavor of broken PDF files that use an "identity" encoding
+		without embedding the font.
+
+		Limited "transfer function" support in PDF. Transfer functions
+		are a deprecated legacy PDF feature that predates proper color
+		management. They were intended to provide limited color
+		management such as applying a gamma curve. Transfer functions
+		have often been (ab)-used to invert images, and many PDF
+		creators use them when writing softmask images. We have added
+		support for this case only.
+
+		Box drawing characters added to fonts for HTML and plain text
+		documents.
+
+		Write more compact PDF files (removed some unneccessary
+		whitespace).

+		Improved handling of CMYK JPEG files (which ones are inverted
+		and which are not).
+
+		Improved content type detection. Don't assume everything is PDF
+		when we can't recognize it.
+
+	Removed deprecated functions:
+		pdf_check_signature
