0.14.0 - 2026-08-29

Added

  • Added cross-platform installed-font discovery through Fontconfig on Linux, Core Text on macOS, and DirectWrite on Windows.
  • Added host resolution for named and generic CSS font families, including serif, sans-serif, monospace, and system-ui. Explicitly configured fonts and @font-face sources retain precedence, and bundled DejaVu Sans is the final fallback.
  • Added the :system_font_discovery HTML-to-PDF option. It defaults to true and can be disabled when identical output across hosts is more important than matching locally installed fonts.
  • Added bounded caching for successful and unsuccessful system font lookups through the max_system_font_cache_entries resource limit.
  • Added browser parity coverage for inherited system fonts.

Changed

  • Changed the default HTML-to-PDF font from a built-in PDF font to bundled DejaVu Sans so text measurement and embedded output use the same face.
  • Updated elixir_font_discovery to 0.2.0 for explicit unavailable-service and variable-font results.
  • System and configured font loading now respects font embedding restrictions exposed by OpenType metadata.

Fixed

  • Fixed variable OpenType fonts being embedded as their default instance. Configured variable fonts now return an actionable diagnostic, while system lookup continues through the CSS fallback list. A static font instance is required for embedding.
  • Fixed scanned PDF streams treating endstream prefixes inside stream data as the end of the stream. Both sides of the keyword must now be valid PDF token boundaries.
  • Fixed font loading stopping at an empty preferred cmap subtable instead of continuing to a later usable subtable.

0.13.0 - 2026-08-27

Added

  • Added NativeElixirPdfUtilities.Info for reading and updating the common PDF information fields title, author, subject, keywords, producer, creation_date, and modification_date.
  • Added Info.page_count/1, Info.page_sizes/1, and Info.encrypted?/1 for validated page counts, effective rotated MediaBox geometry, and encryption detection without attempting decryption.
  • Added incremental information updates through Info.put/2. Updates preserve the original PDF bytes, unspecified fields, unknown information dictionary entries, and the permanent trailer identifier. Passing nil removes a common field.
  • Added :producer to HTML-to-PDF metadata and added max_pdf_info_value_bytes and max_pdf_info_total_bytes resource limits for HTML-to-PDF metadata and information updates.
  • Added a local manual testing application under dev/manual_web with a browser interface and OpenAPI document for rendering, merging, text extraction, information inspection and updates, and tokenization.

Fixed

  • Fixed PDF merging dropping inherited page resources when a page declared /Resources null.
  • Fixed indirect-reference depth and aggregate-work limits being bypassed by stream aliases, cached reference suffixes, or separate page chains.
  • Fixed body content and repeated page furniture receiving separate image budgets instead of sharing the render-wide limits.
  • Fixed merged PDFs and incremental information updates being able to emit an object count that the configured reader limit would reject.
  • Fixed embedded fonts losing Unicode distinctions when two characters mapped to the same glyph. The writer now assigns distinct CIDs and emits an explicit CID-to-glyph map so text extraction preserves both characters.
  • Fixed Type 0 text extraction applying PDF word spacing to a decoded CID or Unicode value instead of only a one-byte source code 0x20.
  • Fixed generated ToUnicode CMaps writing more than 100 entries in one beginbfchar section.
  • Fixed the HTML parser treating > inside quoted attributes as the end of a tag, treating < inside <style> as markup, and mishandling RCDATA in <title> and <textarea>.
  • Fixed Liberation Sans lookup across common Linux installation paths, which restores requested font metrics for right alignment and narrow table headers.

0.12.0 - 2026-08-20

Added

  • Added relative and absolute positioning with top, right, bottom, left, percentage insets, positioned containing blocks, removal of absolute boxes from normal flow, and integer z-index paint ordering.
  • Added object-fit and object-position for replaced images, including fill, contain, cover, none, and scale-down fitting.
  • Added CSS background images with explicit sizes, cover, contain, positioning, and repeat modes.
  • Added :assets and :asset_resolver rendering options. Callers can supply approved bytes or local files without giving the renderer network access.
  • Added browser parity fixtures for positioning, image fitting, background images, and realistic invoice, statement, and multi-page report documents.

Changed

  • Tightened the Chromium changed-pixel thresholds for HTML-to-PDF browser parity fixtures to approximately 5%, with stricter geometric coverage for absolute positioning.
  • Reworked inline, block, table, image, and pagination layout so all 38 synthetic fixtures and 8 realistic documents pass their configured browser parity thresholds.
  • Rewrote the public guides for clearer API contracts, examples, compatibility limits, diagnostics, and browser parity coverage.

Fixed

  • Fixed repeated backgrounds allocating tile coordinates before enforcing the tile limit, and stopped zero-sized background tiles from reaching the PDF writer.
  • Fixed valid background-size: min(...) declarations raising from the public render API.
  • Fixed the background shorthand retaining an earlier background-image when the shorthand omitted an image.
  • Fixed root-positioned boxes moving to later pages during pagination.
  • Fixed collapsed-table background images being painted again after cell content.
  • Fixed positioned inline elements losing their positioned descendants or using the wrong containing block.
  • Fixed mixed inline-block and block children failing layout.
  • Fixed resolver-backed @font-face declarations losing the ordered source candidates needed for fallback.
  • Fixed style diagnostics splitting declarations at semicolons inside URLs.

0.11.0 - 2026-08-17

Added

  • Added static rendering for text inputs, checkboxes, radio buttons, selects, textareas, and buttons. Form state is rendered as deterministic visible PDF content without creating interactive AcroForm fields or widget annotations.
  • Added support for the form type, value, name, checked, selected, and disabled attributes, including valueless and quoted Boolean attributes, selected-option defaults, textarea and button value fallbacks, and strict form-structure validation.
  • Added configurable process-wide resource limits through NativeElixirPdfUtilities.Limits, including validated application startup configuration for HTML, image, SVG, layout, PDF reader, merge, text extraction, CMap, Form XObject, and font-cache workloads.
  • Added a configurable resource-limits guide and browser parity coverage for a static form-control matrix and a realistic government application form.
  • Added a PDF tokenizer guide covering tokens, byte spans, stream-length hints, lexical errors, and the boundary between tokenization and document parsing.

Changed

  • Changed base_url into an explicit authorization root for document-selected images and fonts. Relative and absolute resources must remain beneath the configured root, and traversal and symlink components are rejected; explicitly configured stylesheet files retain trusted local font resolution relative to their own directory.
  • Changed text extraction to cache decoded streams and parsed instructions for the duration of one extraction while still charging every stream use, Form expansion, and executed instruction against aggregate work limits.
  • Changed sparse PDF merging to preflight input count and aggregate bytes and densely renumber reachable source objects before writing the merged cross-reference table.
  • Changed image rendering, complex grid/table layout, PDF reference validation, object-stream parsing, and nested PDF value traversal to enforce their limits before expensive allocation or recursive work begins.
  • Changed the generated ExDoc navigation to keep the changelog prominent, consolidate all license texts under one expandable page, organize the guides by subject, and group public, low-level PDF, HTML pipeline, and validation modules in the API reference.

Fixed

  • Fixed oversized or malformed SVG raster dimensions reaching the native rasterizer before source-byte, per-axis, and total-pixel limits were checked.
  • Fixed repeated images allowing excessive source counts, encoded bytes, or decoded PNG allocation across one HTML render.
  • Fixed complex grid definitions, placements, and table spans performing unbounded work before layout cardinality validation.
  • Fixed shared PDF streams being repeatedly decoded and tokenized during text extraction. A 500-page shared-stream benchmark improved from approximately 3.26 seconds to 28 milliseconds while preserving per-use safety accounting.
  • Fixed PDF object streams scanning oversized headers before their entry count was validated.
  • Fixed sparse PDF inputs causing merge work and output size to scale with high source object numbers instead of the reachable object set.
  • Fixed repeated page-parent and indirect-reference chains being revalidated without request-scoped caching or an aggregate reference-resolution budget.
  • Fixed deeply nested PDF arrays and dictionaries entering recursive descent before the shared value-depth limit was enforced.
  • Fixed local HTML images and document-selected fonts accepting paths outside base_url, including absolute paths, parent traversal, and symlink escapes.

0.10.0 - 2026-08-14

Added

  • Added layered validator modules for shared PDF structure, text extraction, merging, HTML rendering, and PDF writing, with prepared contexts that keep validation separate from execution and serialization.
  • Added NativeElixirPdfUtilities.Pdf.Reader.read_validated/1 for consumers that need the complete shared PDF validation context while preserving the existing read/1 document projection.
  • Added recoverable unsupported-glyph rendering. Missing glyphs now use the Unicode replacement character by default, while unsupported_glyphs: :error retains strict failure behavior with an actionable diagnostic.
  • Added HTML table column definitions through colgroup and col, including column spans, percentage widths, fixed table layout, and separate and collapsed border-spacing behavior.
  • Added documentation for the layered PDF validation pipeline and browser parity fixtures for table column layout, repeated headers near page breaks, border-box sizing, and unsupported-glyph replacement.

Changed

  • Centralized caller input, option, document-structure, and semantic validation in dedicated validators. PDF reading, text extraction, merging, HTML layout, pagination, font fallback, and writing now consume validated and normalized data instead of repeating validation rules in execution code.
  • Separated normalization from validation throughout the HTML renderer so downstream layout and writing stages can rely on stable normalized values.
  • Changed text resource preparation to validate only fonts, encodings, CMaps, graphics states, and Form XObjects reached by executable page content.
  • Changed the HTML renderer and text extraction APIs to reject unknown options with the shared actionable diagnostics contract.

Fixed

  • Fixed PDF validation for page-tree depth limits, /Parent relationships, page aliases, null-valued optional entries, malformed object records, and the required free object-zero cross-reference entry.
  • Fixed stream loading for indirect lengths in ordinary and cross-reference streams, including compressed length objects and stream-boundary ambiguity.
  • Fixed text extraction from ExtGState font selections and Form XObjects with indirect transformation matrices, and rejected unbalanced graphics or text scopes with diagnostics instead of unsafe execution.
  • Fixed merge validation for page resources, terminal page references, top-level page rewrites, exact object generations, and complete indirect reference remapping.
  • Fixed resource bounds for predictor row allocation, CID font width expansion, and page-tree traversal.
  • Fixed repeated table headers overflowing page bounds and page furniture bounds omitting line height.
  • Fixed auto-sized border-box elements losing horizontal padding and bounded emitted PDF color channels to their valid range.

0.9.0 - 2026-08-07

Added

  • Added generated CSS content for ::before and ::after, including quoted content fragments and attr(...) values.
  • Added attribute-presence and attribute-equality selectors, :not(...), odd/even :nth-child(...), and :first-of-type and :last-of-type selectors for document templates.
  • Added named CSS counters through counter-reset, counter-increment, and counter(name), including multiple counters and explicit integer values.
  • Added browser-parity fixtures for generated content, counters, the expanded selector set, and white-space: pre-line rendering.
  • Added a local quality matrix and matching GitHub Actions coverage for the supported Elixir 1.19 and 1.20 runtimes. The matrix checks compilation, formatting, unused dependencies, 100% test coverage, Dialyzer, and Chromium browser parity.
  • Added code-style regression checks for the library's documented public API and function-head conventions.

Changed

  • Changed the minimum supported Elixir version from 1.18 to 1.19.
  • Changed inline whitespace layout to collapse ordinary HTML whitespace across element boundaries, preserve normalized CRLF, CR, and LF line breaks with white-space: pre-line, retain explicit <br> breaks, and treat literal escaped newline sequences as text.
  • Updated GitHub Actions dependencies to Node 24-compatible releases.
  • Refactored HTML-to-PDF parser, style, layout, pagination, page-geometry, page furniture, and PDF visual-comparison internals without changing their public APIs.

Fixed

  • Fixed rgba(), eight-digit hexadecimal, and transparent CSS colors losing their alpha values. Text, backgrounds, and borders now write the required PDF transparency graphics states, including shaded border variants.
  • Fixed PDF merging misclassifying an object as a page when /Type /Page appeared only in a nested dictionary. Page-tree traversal now uses the shared reader's semantic dictionaries and resolves indirect /Kids and /Count values.
  • Fixed stream tokenization allowing a nested dictionary's /Length to replace or leak into the enclosing stream dictionary's length.
  • Fixed source-order text extraction inserting spaces between consecutive PDF text-showing operations. Operator-defined continuity is now preserved across Tj and TJ operands and exposed through each span's joins_previous? field, while positioning, text-object, Form XObject, and graphics-matrix boundaries still begin separate segments.

0.8.0 - 2026-07-30

Added

  • Added opt-in running page furniture through :page_furniture, with independently configured headers and footers, :default, :first, :odd, and :even variants, first-page-only and except-first-page behavior, and {{page}} and {{pages}} tokens.
  • Added complete supported page geometry shared by renderer options and bare @page rules: named and explicit page sizes, portrait and landscape forms, one-to-four-value margins, margin longhands, asymmetric layout, and explicit renderer-option precedence.
  • Added bundled DejaVu Sans regular, bold, oblique, and bold-oblique fonts for deterministic Unicode glyph fallback after requested and configured font families.
  • Added browser-parity coverage for page furniture, page-number tokens, asymmetric page geometry, paragraph fragmentation, border variants, flex and grid constraints, HTML character references, and multi-row table headers.

Changed

  • Changed :stylesheets entries to require explicit {:css, css} or {:file, path} tags. Bare strings are rejected so empty or comment-only CSS cannot be mistaken for a path and file access is always explicit.
  • Changed font loading to reuse successful parsed font files through a supervised, bounded, process-wide cache. Cache entries invalidate when file metadata changes, concurrent cold loads are deduplicated, failed parses are not retained, and no host-application configuration is required.
  • Changed the package metadata and documentation to identify the MIT, Bitstream Vera, and BSD 3-Clause licenses used by the source, bundled DejaVu fonts, and generated WHATWG character-reference data.
  • Documented that repeated page furniture uses the explicit renderer option; CSS position: fixed remains deferred until positioned layout can remove elements from normal flow and apply offsets correctly.

Fixed

  • Fixed CSS cascade precedence so stylesheet !important declarations beat normal inline declarations, while inline !important declarations retain priority over important stylesheet declarations.
  • Fixed table rowspan layout to reserve occupied columns and span the combined height of all covered rows.
  • Fixed paragraphs taller than the remaining or complete printable page being clipped or kept together indefinitely; pagination now fragments them at complete visual lines, including oversized break-inside: avoid paragraphs.
  • Fixed paginated tables repeating only one header row; all <thead> rows now repeat together when the table body continues.
  • Fixed Unicode text being rejected or encoded with the wrong face by resolving each grapheme through the selected, requested, configured, and bundled fallback fonts before layout.
  • Fixed text extraction across nested q and Q operators so saved graphics and text state is restored in LIFO order.
  • Fixed Type 0 text width calculation by mapping source codes through the Encoding CMap before applying descendant CID widths, with strict diagnostics and resource limits for unsupported or malformed CMaps.
  • Fixed merging pages with inherited or indirect MediaBox, CropBox, Resources, Rotate, BleedBox, TrimBox, ArtBox, and UserUnit values by materializing the nearest effective page-tree values.
  • Fixed the shared reader accepting duplicate page-tree references or inconsistent descendant /Count values.
  • Fixed ASCII85 decoding of delimiters, whitespace, z groups, partial final groups, and values that overflow the 32-bit group range.
  • Fixed HTML named and numeric character references using the complete WHATWG table, including legacy semicolon rules, invalid numeric normalization, multi-code-point references, non-breaking spaces, and decode-once behavior.
  • Fixed CSS custom properties being resolved before their cascade completed; ordinary declarations now use the final winning custom-property values.
  • Fixed none, hidden, dotted, dashed, solid, double, groove, ridge, inset, and outset borders, including independent side styles and transparent border spacing.
  • Fixed valid page-context declarations being rejected and malformed size, margin, orientation, marks, bleed, unknown, and incomplete declarations lacking actionable CSS diagnostics.
  • Fixed zero, negative, or excessive margins being accepted when they leave no positive printable page area.
  • Fixed merged output corrupting PDF names that require #xx escaping, including whitespace, delimiters, literal #, control bytes, and non-printable bytes.
  • Fixed unsupported named or pseudo-page selectors and misspelled @page at-rules being silently applied to every page; they now return strict diagnostics.
  • Fixed declaration-order-dependent computed CSS values by resolving em, rem, currentColor, relative semantic margins, custom properties, and inherited line heights against the element's final computed style.
  • Fixed grid minmax() tracks discarding their minimum and added redistribution when fractional tracks reach a minimum bound.
  • Fixed flex grow and shrink distribution overwriting item min-width, max-width, min-height, and max-height constraints.
  • Fixed text extraction rejecting valid inherited indirect page /Rotate values.
  • Fixed merge failures replacing the reader's machine-readable reason and diagnostic stage; callers can again distinguish encryption, page-tree, resource-limit, malformed-input, and unsupported-feature failures.
  • Fixed valid empty or comment-only inline stylesheets and paths containing braces being misclassified by replacing content-based guessing with explicit stylesheet source tags.
  • Fixed the public :default_font typespec so its documented fallback-list form accepts [String.t()].
  • Fixed a severe CSS rem performance regression that recursively traversed complete font registries and decoded runtime payloads for every element. Runtime font and image data is now opaque to CSS length resolution, with a deterministic reductions-based regression test.

0.7.0 - 2026-07-23

Added

  • Added local CSS @font-face support for embedded and configured stylesheets, including font-family, ordered src: url(...) fallbacks, font-weight, font-style, and supported font-display values.
  • Added TrueType font loading from .ttf files and .otf files that use TrueType outlines. Relative font URLs resolve against the configured stylesheet directory or renderer :base_url.
  • Added print media handling for @media print, @media only print, @media all, and @media only all, while non-print media rules are omitted from the active print cascade.
  • Added PDF document metadata through the HTML renderer's :metadata option for title, author, subject, keywords, creation date, and modification date. Metadata dates accept Date, NaiveDateTime, DateTime, and ISO 8601 strings, and non-ASCII values are written as Unicode PDF strings.
  • Added automatic PDF title metadata from the first non-empty HTML <title> when no explicit metadata title is provided.
  • Added Chromium parity coverage for CSS-declared fonts and print media, plus examples and compatibility documentation for fonts, print CSS, metadata, supported formats, URL resolution, and conversion boundaries.

Changed

  • Changed configured stylesheet handling to preserve each file's directory for relative assets and to apply configured @page rules when deriving default page options.
  • Changed explicit and CSS-declared font registration to try ordered local source candidates until a supported font loads.
  • Changed PNG decoding to stream decompression, require the exact expected decoded size, and reject images whose decoded scanlines exceed 100 MB.
  • Changed RunLengthDecode to operate on binaries and enforce the PDF reader's decoded-stream and decompression-ratio limits.
  • Changed text extraction to accumulate spans and output text without repeated list or binary copying, and capped extraction at 25,000 text spans per page with a :resource_limit_exceeded diagnostic.
  • Changed merge failures to retain the PDF reader's reason and stage in the actionable merge diagnostic.

Fixed

  • Fixed merging PDFs that contain unrelated or stale catalog objects by resolving the active catalog from the trailer's /Root reference.
  • Fixed hexadecimal strings with non-hexadecimal bytes being silently sanitized; the tokenizer now emits :invalid_hex_string with the offending byte position.
  • Fixed PDF DateTime metadata formatting so UTC and non-UTC offsets are encoded correctly.
  • Fixed CSS @font-face parsing for quoted URLs containing commas, ordered fallback sources, invalid or missing descriptors, unsupported formats, and malformed declarations.
  • Fixed CSS diagnostics for malformed font and media rules so rendering returns actionable :invalid_css details with source, line, and column context.

0.6.0 - 2026-07-20

Added

  • Added NativeElixirPdfUtilities.Pdf.Reader, a shared PDF document layer with classic cross-reference tables, cross-reference streams, object streams, incremental and hybrid revision chains, recursive indirect resolution, supported stream filters, page-tree validation, and resource limits.
  • Added committed reader fixtures for classic, xref-stream, object-stream, hybrid, incremental, encrypted, and malformed PDFs.
  • Added Text.extract_spans/2 and Text.extract_file_spans/2 for page-preserving decoded text operations with source indexes, baseline coordinates, font and matrix context, and text rendering-mode metadata.
  • Added strict Unicode decoding for standard simple-font encodings, font-specific Differences, Adobe glyph names, Type 0 fonts, and ToUnicode CMaps.
  • Added PDF reader, text extraction, and merging guides covering supported structures, public behavior, diagnostics, limits, and known boundaries.
  • Added GitHub Actions checks for compilation warnings, formatting, unused dependencies, tests, 100% coverage, Dialyzer, and Chromium browser parity.

Changed

  • Changed text extraction and PDF merging to consume the shared reader model so both utilities honor active revisions, generations, free entries, compressed objects, and the validated page tree.
  • Changed text extraction to reject malformed content and unreliable font encodings with actionable diagnostics instead of guessing or returning partial text.
  • Changed string extraction to project from the same positioned page spans while preserving the existing layout: true and layout: false output.

Fixed

  • Fixed merging pages with malformed inherited /MediaBox values by applying the default page box.
  • Fixed valid cross-reference offsets that point to PDF whitespace immediately before an indirect object header being rejected.
  • Fixed tokenizer comments ending at end-of-input being emitted as tokens.

0.5.1 - 2026-07-10

Changed

  • Merge.merge/1 now rejects malformed classic PDF input with an :invalid_pdf_input diagnostic rather than producing an empty PDF or raising.
  • NativeElixirPdfUtilities.Tokenizer now emits explicit error tokens for unterminated literal and hexadecimal strings.
  • Text.extract/2 rejects malformed token streams with an :invalid_pdf_input diagnostic. It also ignores unusually large ToUnicode CMaps to bound memory and CPU use during extraction.

Fixed

  • Fixed merge crashes caused by malformed tokens, incomplete streams, duplicate object identifiers, and invalid object identifiers.
  • Fixed merged PDFs losing inherited /MediaBox and /Resources values from intermediate /Pages tree nodes.
  • Fixed remapping of non-page /Parent references during a merge.
  • Fixed malformed TTF font input causing HTML-to-PDF rendering to crash.
  • Reduced avoidable repeated binary and list copying while writing larger PDFs.

0.5.0 - 2026-07-10

Added

  • Added NativeElixirPdfUtilities.Diagnostics as the shared public diagnostic contract.
  • Added standardized diagnostic details for merge, text extraction, HTML rendering, pagination, PDF writing, and file failures.
  • Added developer guidance for using the shared diagnostics contract in future public APIs.
  • Added a diagnostics guide under docs/.

Changed

  • Changed Merge.merge/1 to return diagnostic errors instead of raising for empty input.
  • Changed recoverable failures from merge, text extraction, HTML rendering, pagination, PDF writing, and file operations to return {:error, {reason, diagnostic}} with :stage, :reason, :message, :operation, :module, and :source context when available.

0.4.0 - 2026-07-09

Added

  • Added a Chromium-backed browser parity test suite for the supported HTML/CSS rendering surface.
  • Added browser parity fixtures for common layout, CSS cascade, tables, flexbox, grid, pagination, image, link, unit, and production-document scenarios.
  • Added browser parity coverage documentation so supported renderer behavior is tied to explicit fixtures.

Changed

  • Improved HTML-to-PDF browser accuracy for nested table, flexbox, and grid compositions.
  • Improved collapsed table border sizing and painting to better match browser output.
  • Improved @page handling in parity tests so native and Chromium renders use the same page size and margins.
  • Updated contribution guidance to require focused tests and browser parity coverage for visible HTML-to-PDF feature work.

Fixed

  • Fixed CSS custom property resolution inside supported compound values such as padding and side-specific borders.
  • Fixed box-sizing: border-box handling across block, flex, grid, table, and image layout paths.
  • Fixed table layout inside flex and grid items, and flex layout directly inside table cells.
  • Fixed declared table row heights and pagination metadata propagation for table rows.
  • Fixed pagination edge cases around first-page parent padding, overlapping parent/child groups, and zero-height metadata groups.

0.3.0 - 2026-07-08

Added

  • Added NativeElixirPdfUtilities.HtmlToPdf, a native HTML/CSS to PDF renderer for document-oriented templates.
  • Added support for common document HTML including text, headings, paragraphs, spans, lists, links, tables, images, and nested document structure.
  • Added support for common print-oriented CSS including cascade handling, box model sizing, text styling, borders, backgrounds, tables, flexbox, grid, page sizes, page breaks, and @media print behavior.
  • Added embedded image, SVG rasterization, and custom TTF font rendering support for generated PDFs.
  • Added multi-page pagination and PDF writing for rendered HTML documents.
  • Added detailed render diagnostics for invalid HTML, unsupported HTML, invalid CSS, invalid layout, and invalid document failures.
  • Added fixture coverage for purchase orders, material requisitions, stock stickers, and trim cards with realistic scrambled data.
  • Added dedicated HTML-to-PDF compatibility and examples documentation.

Changed

  • Updated the package description to include native HTML/CSS rendering.
  • Updated HexDocs metadata to include the HTML-to-PDF guides.

0.2.0 - 2026-07-03

Added

  • Added embedded text extraction so callers can consume readable text data from PDF binaries.

Changed

  • Refactored tokenizer, merge, and text internals to use explicit case/cond branching instead of guarded multi-head private functions.
  • Split tests into focused tokenizer, merge, and text suites.
  • Improved package documentation and HexDocs metadata for the release.

Fixed

  • Fixed page dictionary rewriting around empty arrays and MediaBox validation.
  • Added 100% test coverage across the current public library modules.

0.1.0 - 2025-09-08

Added

  • Initial PDF tokenizer.
  • Initial PDF merge utility.
