Ghostscript full changelog

The old, PostScript based PDF interpreter has been removed, it is no longer available.
We've continued to improve the performance of the PDF interpreter written in C and improve it's behaviour in edge and out-of-specification cases.
Our efforts in code hygiene and maintainability continue, with a particular focus on fuzz testing.
The usual round of bug fixes, compatibility changes, and incremental improvements.

This release (10.02.0) marks the final demise of the PostScript based PDF interpreter.

Old PDF Interpreter deprecated, and we will no longer maintain that code.

Highlights in this release include:
Overprint simulation is now available to all output devices, allowing quality previewing/proofing of PostScript and PDF jobs that rely on overprint. See the -dOverprint option documentation in: Overprint
The "docxwrite" device adds the ability to output to Microsoft Word "docx" (it currently only handles text). See: docxwrite
The pdfwrite device is now capable of using the Tesseract OCR engine when it is built into Ghostscript to improve searchability and copy and paste functionality when the input lacks the metadata for that purpose. See: UseOCR
Ghostscript/GhostPDL now includes a "map text to black" function, where text drawn by an input job (except when drawn using a Type 3 font) can be forced to draw in solid black. See: BlackText
Ghostscript/GhostPDL now supports simple N-up imposition "internally". See: NupControl
Our efforts in code hygiene and maintainability continue.
