Release notes

Sourced from fpdf2's releases.

Improved PDF standards compliance, page number alias substitution, and rendering, plus other bug fixes

[2.8.9] - 2026-09-29

Added

• align parameter for FPDF.alias_nb_pages() to control horizontal alignment (Align.L, Align.C, Align.R) of substitution text inside reserved alias space - cf. [issue #1926](py-pdf/fpdf2#1926) - thanks to @​prateek-dagar
• support for page number alias substitution with bidirectional / RTL text shaping - cf. [issue #1925](py-pdf/fpdf2#1925) - thanks to @​prateek-dagar
• appearance parameter for FPDF.file_attachment_annotation(), accepting FileAttachmentAppearance.HIDDEN to give the annotation an empty appearance stream so its default icon is not displayed while the file stays embedded and reachable - cf. [issue #561](py-pdf/fpdf2#561) - thanks to @​ChrisJr404
• Turkish translation of the Tuto 7 - Creating PDF/A Documents tutorial section, along with fixes for duplicated clauses and mistranslations in the Tuto 2, 4 & 6 descriptions - cf. [PR #1951](py-pdf/fpdf2#1951) - thanks to @​ihsandeniz

Fixed

• escaped Markdown markers adjacent to emphasis markers in link labels no longer lose literal characters or apply unintended styling
• PDF serialization of boolean and null values: booleans in arrays and dictionaries now use lowercase true and false, including in mixed numeric/boolean arrays; None in arrays is serialized as null; and filtering empty dictionary fields preserves False and numeric zero values - thanks to @​agustin18
• SVG percentage width and height values with surrounding whitespace (e.g. width="100% ") no longer raise ValueError - thanks to @​Anai-Guo
• PDF/A-1 documents using TrueType or CFF-based CID fonts now include a /CIDSet stream in each font descriptor, as required by ISO 19005-1 (veraPDF rule 6.3.5-3) - cf. [issue #88](py-pdf/fpdf2#88)
• split font /ToUnicode and /Encoding CMap mappings into blocks of at most 100 entries, as required by the PDF specification - cf. [issue #1952](py-pdf/fpdf2#1952)
• visual gap in rendering subsequent text after {nb} page alias when text shaping is enabled - cf. [issue #1090](py-pdf/fpdf2#1090) - thanks to @​prateek-dagar
• FPDF.write_html() no longer raises IndexError: pop from empty list when a <ul> or <ol> element carries a line-height that is not a bare number (e.g. line-height: normal or line-height: 1.5em); such values are now ignored, and the default line height is used, consistently with <p line-height="x"> - thanks to @​Anai-Guo
• FPDF.write_html() now renders list bullets with correct font styling instead of inheriting preceding heading (e.g. <h1>) styles - cf. [issue #1921](py-pdf/fpdf2#1921) - thanks to @​prateek-dagar
• table cells landing in the wrong column when a row was covered by several rowspans that did not start in column order - cf. [issue #1948](py-pdf/fpdf2#1948)
• Padding.new() now accepts 1-element sequences per CSS shorthand rules and preserves existing Padding instances without redundant allocations

Changed

• Refactored _tt_font_widths to reuse _cid_font_widths glyph interval compression logic - thanks to @​agustin18
