Released: Mar 31, 2026

Updates in 2026.4.1

Features

• Improved PDF rendering performance by reducing internal render calls and reusing browser tabs to minimize startup overhead.
• Added compressAndSaveAs() method to compress a PDF and save it directly to a file path.
• Deprecated compressImages() in favor of compressAndSaveAs(), compressPdfToBytes(), and compressPdfToStream().

Fixes

• Fixed memory leak in replaceText() where repeated calls caused increasing memory growth (93–97% reduction).
• Fixed buffer over-read in metadata retrieval that could cause crashes or data corruption.
• Fixed an issue where PDF/UA conversion removed CSS overflow:hidden clipping, ensuring clipped images render identically to standard PDF output.
• Fixed an issue where signatureName was always empty when verifying signatures created by external signers such as Adobe Reader.
