2026.5.2 버젼 업데이트

기능

• Added SignerCertificate and CertificateChain properties to VerifiedSignature, exposing full X.509 certificate details including Subject DN, Issuer, Serial Number, validity period, and raw DER bytes from digitally signed PDFs.
• Added LinkAnnotation class for creating clickable links within PDF documents that navigate to specific pages and positions.
• Added LinearizePdfToBytes and LinearizePdfToStream methods, enabling fully in-memory PDF linearization without disk I/O, ideal for cloud-based and sandboxed environments.
• Added automatic PDF bookmark generation from HTML headings (h1–h6) during rendering, including correct hierarchy, page mapping, and optional filtering by heading level or CSS selector.
• Rebuilt qpdf 12.3.2 with statically linked libjpeg and zlib, removing dependency on system libjpeg.so.62 for IronPdf.Linux and ensuring compatibility with modern Linux distributions such as Rocky 9/10 and Debian 13.
• Updated internal dependencies.

수정사항

• Fixed an issue where HTML headers and footers did not scale correctly when using UseFitToPageRendering() or UseScaledRendering() with non-default zoom levels.
• Fixed intermittent IronPdfInputException when rendering headers/footers with FragmentHeight on custom paper sizes.
• Fixed intermittent SEGFAULT during process teardown and improved tab pool stability to prevent concurrent rendering issues and log spam.
