Bump QuestPDF from 2025.4.0 to 2026.8.0

[dependabot]

Updated QuestPDF from 2025.4.0 to 2026.8.0.

Release notes

Sourced from QuestPDF's releases.

2026.8.0

🚀 This release is dedicated to performance, parallelism, and use of available resources. 🚀

Documents render faster, allocate a fraction of the memory they used to, and scale across all available CPU cores. No code changes are required — existing documents benefit simply by upgrading the package.

The numbers below were measured on a MacBook Pro M5 (18-core CPU), using the invoice document from the Getting Started tutorial, across various levels of parallelism, over a sample of 5,000 documents.

• Reduced allocated memory amount and allocated object count by 85%.
• Improved single-threaded performance by around 15%.
• Substantially improved parallel scaling: throughput previously peaked at 4 threads and flattened beyond that, and now scales with available CPU cores — with around 4x better scaling.
• Improved performance and scalability for text-heavy documents.
• Improved cache usage (mainly for fonts) and significantly reduced locking.

✨ Other improvements:

• Added support for soft hyphens: the library does not hyphenate text automatically, but soft hyphen characters (U+00AD) are now correctly interpreted as optional break points and rendered as hyphens when a line breaks.
• Added the TextStyle.BreakAnywhere API, which allows a text span to break between any two characters, not only at word boundaries such as spaces or hyphens. Useful for content without natural break points, e.g. long URLs, identifiers, hashes, or file paths.
• Improved the visual position of the underline and double underline text decorations.
• Improved reliability of the Companion App integration: document previews are now refreshed from a consistent snapshot, and rendered pages are transferred more efficiently.
• Increased the zlib compression level used for PDF generation from 1 to 3, which produces significantly smaller files (for text-heavy documents) with a minimal increase in generation time.
• Updated the Skia native dependency to version m152.

⚠️ Breaking change

XPS generation has been removed. The format was supported only on Windows, had several rendering issues that could not be reliably resolved, and had negligible adoption. The GenerateXps and GenerateXpsAndShow methods are still present, but calling them now results in a compilation error, and code compiled against an earlier version throws an exception at runtime. Please use PDF generation instead.

2026.7.3

• Breaking change: The Rotate API now rotates elements around their center instead of the top-left corner. Center-origin rotation is the expected behavior in virtually all use cases.
• Behavioral change: Generated images now use a white background by default, so the output matches how the document appears in a PDF viewer. Previously, PNG and WEBP images had a transparent background. To restore the old behavior, enable ImageGenerationSettings.UseTransparentBackground (applies only to formats supporting transparency: PNG and WEBP).
• Automated table semantic tagging is now applied whenever a Table element is placed inside a SemanticTable container, even indirectly. Nested semantic captions are now supported as well.
• Image elements now emit the /BBox attribute, improving PDF/UA-1 compliance with validators that require it.
• Improved the stability and speed of the QuestPDF Companion integration. The integration now requires .NET 8 or newer.
• Improved the developer experience of the GeneratePdfAndShow and GenerateXpsAndShow methods.
• Deprecated AsSemanticHorizontalHeader in favor of SemanticHorizontalHeader for API naming consistency.
• Deprecated RotateLeft and RotateRight in favor of RotateLayoutCounterclockwise and RotateLayoutClockwise, which better describe what these methods do.

2026.7.2

• Fixed a rare Windows x64 concurrency issue where generated PDF documents appeared correct in viewers, but selected and copied text was corrupted.
• Improved text rendering representation to resolve rare compatibility issues in certain PDF viewers that could cause incorrect results when selecting or copying text.
• Improved compatibility for complex glyphs, such as ligatures, by annotating them with the /ActualText tag. This improves text selection, copying, extraction, and screen-reader accessibility. Ligatures remain disabled by default.
• Added support for the AllowModification permission in DocumentOperations when encrypting PDF documents with 128-bit or 256-bit keys.
• Added minor fixes and expanded test coverage for the DocumentOperations API.

2026.7.1

Improved performance

PDF generation is now significantly faster. The Skia native dependency has been recompiled with speed-oriented optimizations (favoring performance over binary size) and with SIMD instructions enabled.

The impact depends on document content and platform. For example, generating image-heavy documents that require image rescaling can be several times faster on Windows x64 🎉

Note: this change slightly increases the size of the native dependency by around 20%.

Continuous performance monitoring

We have also built a solid foundation for measuring library performance going forward. A new GitHub Actions workflow benchmarks QuestPDF across all supported operating systems, processor architectures, and .NET releases.

This infrastructure helps us ensure that performance remains stable and consistent across all platforms, and allows us to detect regressions early — before they ever reach a release.

For more details on both features, please see: QuestPDF/QuestPDF#1177

2025.7.4

• Fixed the DocumentOperation.ExtendMetadata operation to preserve /Metadata tag attributes (/Subtype /XML) and improve compatibility with the Mustang validation tool for ZUGFeRD files.

2025.7.3

• Fixed an issue that caused the PDF generation process to fail when the application lacked file access permissions to the default temporary folder.
• Added support for specifying a custom temporary storage path through the QuestPDF.Settings.TemporaryStoragePath property.

2025.7.2

• Disabled standard ligatures by default, as they often interfere with text copying and may pose accessibility issues,
• Performance has been improved when generating multiple text-heavy documents at the same time. The more concurrent operations and text elements involved, the more noticeable the benefit,
• Improved the developer experience by updating the behavior of the GeneratePdfAndShow method to always create a uniquely named file. It ensures that certain PDF viewers automatically refresh the preview,
• Fixed exception triggered when generating a PDF without defining a Page in the Fluent API,
• Increased test coverage,
• Minor bug fixes and improvements.

2025.7.1

• Fixed a significant memory leak in document operations involving overlay or underlay,
• Fixed a minor memory leak in general document operations (e.g., merge, save with password),
• Updated the Skia dependency to M140,
• Removed unnecessary dependencies on Linux and macOS (OpenSSL, libjpeg-turbo) to improve compatibility across more platforms.

2025.7.0

• Line element: Added gradient and dashed pattern support
• Background element: Added linear gradient (multiple colors, arbitrary angle) and rounded corners
• Border element: Added linear gradient (multiple colors, arbitrary angle), rounded corners, and alignment options (inside, outside, center)
• Shadow element (new): Added blur, color, offset, and spread support
• Internal: Introduced visual snapshot testing for the generation process
• Updated Skia dependency to M138

2025.6.0-rc0

• Line element: Added gradient and dashed pattern support
• Background element: Added linear gradient (multiple colors, arbitrary angle) and rounded corners

• Reduced peak memory usage when generating PDF files by properly implementing a stream-based API,
• Fixed the exception message displayed when the library cannot successfully parse the provided text as a color.

2025.5.0

• Feature: Added the CaptureContentPosition API, allowing developers to inspect the exact position and size of arbitrary content. This enables the generation of dynamic, related content within the DynamicComponent, enhancing flexibility for complex layout requirements.
• Enhancement: Changed the default page background color from white to transparent, which reduces developer confusion during document operations such as content overlaying. Only JPEG images are rendered with a white background.
• Fix: ShowIfContext.TotalPages is now set to null during the initial rendering phase to avoid confusion when using the ShowIf API.
• Fix: Improved memory management in the Companion App workflow by immediately disposing of native resources.
