Release notes

Sourced from pdf_oxide's releases.

v0.3.55 | Ruby + PHP language bindings + multi-line heading reading-order fix

Added

• Ruby binding (9th language) — full PDF toolkit for Ruby. Install with gem install pdf_oxide. Prebuilt native gems for linux-x86_64, linux-aarch64, darwin-x86_64, darwin-arm64, windows-x64 plus a source gem. API mirrors the Java binding's 9-class shape (PdfDocument, Pdf, PdfPage, PdfPolicy, PdfSigner, PdfValidator, DocumentEditor, AutoExtractor, MarkdownConverter) so docs and examples are uniform across languages. Full feature parity with Python / Java including auto-extraction, PAdES B/T/LT signing, destructive redaction, office round-trip, and split-by-bookmarks. (#545)
• PHP binding (10th language) — full PDF toolkit for PHP. Install with composer require oxide/pdf-oxide. PHP 8.2 / 8.3 / 8.4 / 8.5 on Linux / macOS / Windows. Same 9-class API shape as Ruby and Java. Composer post-install hook fetches the matching prebuilt libpdf_oxide per platform with SHA-256 verification. Full feature parity with Python / Java. Requires ext-ffi. (#546)

Fixed

• #543 — Long subsection titles in multi-column academic papers no longer split when they wrap across column boundaries. Discovered while regression-testing v0.3.54 on a 75-PDF corpus.
• #537 (follow-up) — Markdown output now emits Unicode bidi-isolation markers around RTL runs detected by the v0.3.54 Hebrew / RTL detector, so extracted Hebrew / Arabic text renders correctly inside mixed-direction paragraphs. Original report by alexagr; this completes the markdown emission half deferred from v0.3.54.
• #535 (follow-up) — Type 1 built-in encodings, CFF charset, and /Differences-array glyph lookups now go through the same Adobe Glyph List fallback chain as v0.3.54's main extractor, with variant-suffix stripping (A.sc → A, bullet.alt → •, fi.001 → fi). Resolves replacement-character (�) leakage on PDFs using simple-font encodings without a ToUnicode CMap.

[0.3.54] - 2026-05-23

Text-extraction fidelity pass. Hebrew / RTL reads in correct reading order thanks to a new geometric visual-vs-logical detector that finally fires on Hebrew (Pass 0's Arabic-Presentation-Forms gate never matched Hebrew because Hebrew has no presentation forms in Unicode). Bullets and fi / fl ligatures decode to their canonical codepoints via a new ISO 32000-1 §9.10.2 fallback level — Type0 Identity-H fonts without a CIDToGIDMap now consult the embedded TrueType cmap + post tables before the
