Scripting

• Extended hint when built-in definitions are shadowed to set and show rules
• Added hint when trying to spread one or multiple dictionaries into an array
• Improved diagnostics for invalid method calls
• Improved hint for unknown variables in math that are available in std
• Fixed a misleading error message when trying to assign to a temporary return value

Library

Foundations

• Added file path type that is now accepted in all places where paths were previously only represented as strings
  • A path constructed in one file can be used in another file, but will be resolved relative to its original file
  • Likewise, paths can be passed across package boundaries
  • The initial path type is very minimal, but additional features like file existence checks or directory walking are planned
• Collections
  • Added map and filter functions on dictionaries and arguments
  • Named arguments on arguments values are now accessible with field access syntax
  • The slice functions on strings and arrays will now error if passing both an end and a count (Minor breaking change)
  • Added inclusive parameter to range function
• Calculation
  • Added asinh, acosh, atanh, and erf functions to calc module
  • Added int.min and int.max constants for the minimum and maximum representable integer, respectively
  • Fixed behavior of quo for negative integers
  • Fixed potential overflows in norm, abs, gcd, and lcm
  • Floating-point calculations are now consistently deterministic across platforms
• Date & time handling
  • The offset parameter of datetime.today now accepts durations as an alternative to integers, allowing for sub-hour precision offsets
  • Addition and subtraction of datetimes and durations now retains precision instead of clamping to full days in some cases
  • The datetime constructor now emits more precise errors when components are missing
• Conversions
  • Added base parameter to int constructor to configure in which base to parse a string
  • Fixed that the base parameter of the str constructor was accepted for non-integer values if its value was 10 (Minor breaking change)
  • Added hint when trying to construct a string with base 1
• The panic function now displays strings as-is instead of showing their repr, making it more suitable for friendly, user-facing messages
• Changed repr of styles and locations to be more distinct

Model

• Added divider element representing a thematic break that templates can style
• Bundle-related elements
  • The document element can now be constructed to produce individual documents in bundle export
  • Added path and format parameters to document element
  • Added experimental asset element
• Bibliography management
  • A single document can now contain multiple bibliographies
  • Added target parameter to bibliography element to configure which citation is picked up by which bibliography
  • Added group parameter to bibliography element to configure how numbers are shared/reset across bibliographies
  • Added support for numeric values for the month key in .bib files
  • Added support for BibLaTeX name options in .bib files
  • Added support for propagating non-numeric volume fields in .bib files to bibliographies
  • Improved sorting in bibliographies to take into account language conventions
  • Improved interoperability with CSL styles; for a full listing of changes, review the Hayagriva 0.10.0 changelog
  • Added support for setting directors on videos without a parent in Hayagriva YAML files
  • Improved handling of Anthos entries in Hayagriva YAML files by treating them as chapters in CSL
• Footnotes
  • The link of a footnote is now within the superscript instead of around it, improving PDF tagging and HTML output
  • The thickness of the default footnote separator is now specified in font-relative instead of absolute units
• Numbering
  • Added numbering support for Armenian numerals , Arabic Abjad numerals , and Tibetan numerals
  • Greek numbering now uses the modern Greek style
• The par.first-line-indent property will now fold, meaning that partial dictionaries across different set rules or par calls are combined
• Added list.marker-align property for defining how to align list markers
  • When omitted, it will default to the new baseline alignment (vertically), combined with end alignment (horizontally)

Text

• Added support for variable fonts
  • The well-known variation axes ital, slnt, wght, wdth, and opsz are automatically set based on text weight, stretch, style, and size
  • Custom variations can be configured via the new variations parameter of the text function
  • When using a variable font with Typst, the suffixes "Variable", "Var", and "VF" should be omitted as Typst trims them to unify static and variable fonts into a single family (Minor breaking change)
• Font features
  • The text.alternates parameter now accepts an integer in addition to a boolean to select stylistic alternates other than 0 and 1
  • Parsing of tag names in text.features is now more strict (Minor breaking change)
• Fixed that context text.font did not reflect the covers field
• Fixed uneven CJK-Latin spacing in justified paragraphs
• Fixed a bug where the lorem function would not produce the exact number of requested words
• Improved translations for Swedish , Portuguese , Czech , Latvian , Slovak , Polish , Vietnamese , Finnish , and Welsh
• Added font exception to avoid SimSun-ExtB being incorrectly merged with SimSun
• Updated New Computer Modern fonts to version 8.1.0
  • This update changes the default look of calligraphic letterforms in the math font; the previous style can be restored through show math.equation: set text(stylistic-set: 6)
• Updated Unicode components
  • In particular, this fixed an issue with linebreaking of guillemets

Math

• Layout
  • Improved layout of under/over elements like underbrace
  • Slightly improved spacing around math.op elements
  • In which situations cramped styles (with tighter spacing) are applied is now fully consistent with TeX and MathML Core
  • The size parameter of the lr function now consistently applies to middle delimiters in the same way it does to outer delimiters
  • The size parameter of the lr function now resolves relatively to the height of just the inner content; it does not take the delimiters into account anymore (Minor breaking change)
  • Glyph stretching is now always relative to the base glyph rather than a potentially already scaled version (e.g. due to display sizing) (Minor breaking change)
  • Fixed left/right alignment not being applied correctly due to spacing next to alignment points
  • The binom element now uses different OpenType constants for layout; though this does not lead to visible changes with most fonts
  • The default length and stroke width of math.cancel lines is now specified in font-relative instead of absolute units
  • Fixed potential misalignment in cases function
• Text handling
  • Improved handling of multi-character symbols in math
  • Fixed that some glyphs did not stretch correctly in script sizes
  • Fraction, root, and under/over lines now respect text.stroke
  • Accents in math are now always rendered in front of their base if they overlap
• The class function now applies the class only to its direct body rather than recursively (Minor breaking change)
• More delimiter symbols (e.g. chevron.l) are now callable to produce an lr element (Minor breaking change)
• Fixed various bugs with rendering of mathematical expressions that look like function calls but in reality aren't (e.g. $pi(1, 2)$, since pi is not a function)
• Fixed a bug with ordering of primes and nested attachments

Symbols

• Added many new symbols and variants. View the codex 0.3.0 changelog for a full listing.

Layout

• Baseline information is now retained in many more parts of the layout engine (Breaking change)
  • In particular, text contained in a box with an inset is now aligned with the text surrounding the box
  • This also fixes a bug where wrapping an inline equation in a box would shift its baseline
  • Similarly, using a block in an equation will keep the baseline intact
  • Last but not least, the marker/number and item of a list or enum are now properly baseline-aligned with the first line of the item even if the item is vertically larger than a normal line
• Centering something in a list now centers based on the full available width rather than based on the maximum width of other list content
• Page layout
  • Added bleed parameter to page element to set up bleed margins
  • Fixed the size of "us-executive" paper
  • Added warning for show page rules as they are unsupported
• Paragraph layout
  • Fixed a bug where justified text could accidentally protrude into the margin when it ends with certain kinds of characters (e.g. a zero-width space)
  • Fixed a bug where first-line indent was applied at the start of a column even if all: false is set
• Added support for spacing that is both weak and fractional

Visualize

• Added support for spot colors (also called separation colors)
• Tilings
  • Added offset parameter for shifting the starting position of a tiling
  • Fixed parent-relative placement for stack and polygon
• Gradients
  • Added color.map.coolwarm for use with gradients
  • Fixed interpolation of gradient stops in Oklab color space
  • Fixed gradient angle handling for negative-size shapes
  • Fixed gradient strokes for lines and curves
  • Fixed parent-relative placement for stack and polygon
• Fixed various bugs with rectangle strokes in combination with radii
• Fixed a potential deadlock with font fallback in SVGs
• Various improvements to SVG image handling (see the resvg 0.46 and 0.47 changelogs); in particular:
  • Added support for SVGs without top-level xmlns attribute
  • Added support for variable fonts in SVG using the font-variation-settings CSS property
• Various improvements to PDF image handling (see the commits between d0b540f and 3483462 on hayro); in particular:
  • Added support for JPEG2000 (JPXDecode) and JBIG2 (JBIG2Decode) images
  • Improved parsing robustness for non-compliant files
  • Added support for blend modes

Introspection

• Layout convergence issues now result in detailed diagnostics that help pin down the cause
• Added within selector that matches elements that are contained within any elements matching an ancestor selector
• Added at parameter to counter.display function
• Improved how counter.display auto-selects the numbering to use

Data Loading

• Added support for namespaces to xml function
• Added hint when trying to read from a path that looks like a URL
• Diagnostics for binary file loading failures now include file paths
• The json function now emits a friendly error when the loaded JSON has a leading UTF‑8 BOM

Export

Bundle

• Added new, experimental bundle export target
  • With bundle export, you can emit multiple output files from a single Typst project
  • Bundles can contain any combination of HTML pages, PDFs, PNGs, SVGs, and arbitrary assets

HTML

• Mathematical equations are now automatically exported to MathML (thanks to @mkorje)
  • MathML defines how to render an equation, but also preserves its semantics
  • If you've previously relied on show rules that use html.frame to render equations to SVG, try MathML output. Switching to it will improve the accessibility of your document (though rendering will be somewhat less consistent across browsers).
• The box and block elements' purpose is now aligned with paged export (Breaking change)
  • box is used to bring block-level content inline
  • block ensures inline-level content becomes block-level
  • Depending on the contained content, this may be achieved by setting the CSS display property or by wrapping in an additional <span> or <div>.
• The rules of how paragraphs are grouped in HTML have been adjusted to fix cases where paragraphs would appear unexpectedly (Breaking change)
  • The list of HTML elements that can be grouped into paragraphs was tweaked (it now includes all phrasing content with the exception of elements that default to display: none)
  • This default can be controlled by wrapping an element in a box or block as appropriate
  • HTML elements that cannot be part of paragraphs (like a <div>) do not immediately force adjacent inline-level Typst content to be wrapped in a paragraph; rather, they are considered neutral for paragraph grouping
  • Paragraph creation is only forced by block-level Typst elements (as opposed to HTML elements). Built-in block-level elements like headings or images wrap the HTML elements they create in block elements to force adjacent inline content into paragraphs. Package authors should do the same to ensure paragraph creation is consistent between HTML and paged export.
• The target function can now be used without the html feature flag (the rest of HTML export remains feature-flagged)
• DOM structure and built-in show rules
  • The root <html> element now receives a lang attribute respecting what was configured for text.lang
  • The Typst image element now always emits width and height attributes on the generated HTML <img> element
  • Code in <pre> tags will now prefer raw newlines over <br> elements to encode line breaks
  • Fixed generated HTML for quote attributions
  • Fixed table cell show rules not working in HTML export
• Serialization
  • HTML is now minified by default; use the --pretty CLI flag or the checkbox in the web app to pretty-print it
• HTML elements
  • The attrs parameter on html.elem will now fold, meaning that partial attributes across different set rules or html.elem calls are combined
  • html.script and html.style only accept a string and not arbitrary content anymore (Breaking change)
• Whitespace handling
  • HTML <br> elements now collapse adjacent Typst spaces
  • Fixed spans being emitted to protect whitespace from collapsing unnecessarily in some cases

PDF

• Typst can now target multiple (compatible) PDF standards at once, e.g. PDF/UA-1 and PDF/A-2a
• PDFs are now a bit more space-optimized at the cost of being harder to inspect with a text editor; use the --pretty CLI flag or the checkbox in the web app to pretty-print them
• Labelled headings now result in named destinations even if they are not referenced
• Graphics
  • Added support for more compositing features of COLRv1 fonts
  • Fixed rendering of gradients in LinearRGB, CMYK, and Luma color spaces
  • Fixed excessive sampling of linear gradients
• Tagging
  • Added support for more specific artifact kinds in pdf.artifact; these are now internally used when appropriate
  • Fixed "invalid document structure" errors with complex list markers
  • Fixed wrong PDF tagging order for inline content outside of paragraphs
  • Fixed bounding box computations for stroked shapes in tagged PDFs
• Standards compliance
  • Fixed potentially incompliant PDF files by emitting an error when PDF/UA-1 is requested but complying with PDF/UA-1 would require newer features than available in the current PDF version
  • Fixed potentially incompliant PDF 1.4 files by emitting errors when implementation limits are exceeded

SVG

• SVGs are now minified by default; use the --pretty CLI flag or the checkbox in the web app to pretty-print them
• Somewhat reduced the size of generated SVGs
• SVG elements do not have the classes typst-frame, typst-doc, typst-group, typst-shape, and typst-text anymore (Minor breaking change)
• Graphics
  • Fixed a bug where tilings could be incorrectly reused in multiple places
  • Fixed rendering of gradients in LinearRGB, CMYK, and Luma color spaces
  • Fixed handling of conic gradient angles
  • Fixed excessive sampling of linear gradients
• Fixed positioning and sizing of color bitmap glyphs
• Fixed sources of non-determinism in SVG export

PNG

• Fixed handling of conic gradient angles
• Fixed positioning and sizing of color bitmap glyphs
• Fixed that negatively scaled text with equal x and y scale would turn invisible in PNG export

Command Line Interface

• Added new typst eval subcommand to evaluate a Typst code expression from the CLI; this command supersedes typst query
• Tracebacks for diagnostics are now more compact and readable
• Added --pretty flag for producing human-readable output; output is otherwise minified by default (applies to HTML, SVG, and PDF, but not PNG)
• Fonts
  • The output of typst fonts --variants is now more readable and informative; in particular, it also displays the paths of font files and, for variable fonts, variation axes
  • The CLI now discovers fonts lazily, saving time on operations that do not need fonts (like HTML export without frames)
  • Adobe Creative Cloud fonts are now discovered as system fonts
• Dependency output
  • When writing to stdout while using --deps-format make (which is incompatible and thus fails), no empty Make dependency file will be emitted anymore
  • The JSON dependency format now includes information about outputs in addition to inputs
• Path handling fixes on Windows
  • Reading from a path that contains a drive letter now results in an explicit error instead of the drive letter being silently ignored
  • Attempting to read from a path that contains a reserved filename (like COM1) now results in an explicit error
• Non-Unicode input paths are not supported anymore (Breaking change)
• The experimental --timings argument now requires an explicit file name instead of defaulting to record-{n}.json (Breaking change)
• Added colors to --help/-h and typst info output
• Fixed inconsistency in environment variable handling between typst info and typst compile
• Fixed a bug with the injection of a live reload script when using typst watch with HTML export
• Fixed a bug where local timezone information was taken into account even if a fixed date is set via --creation-timestamp or SOURCE_DATE_EPOCH, leading to irreproducible results

Tooling

• Syntax highlighting
  • In math, parentheses used for grouping are now highlighted differently than ones intended for display
• Autocomplete and tooltips
  • Autocompletion and tooltips are now aware of parameters of user-defined functions
  • Autocomplete descriptions and tooltips for font families are now more detailed and, for variable fonts, include variation axes
  • Function autocompletions in math mode now always prefer round parentheses over square brackets (which are not supported in math)
  • Fixed autocompletion and tooltips not working with argument lists in math mode

Deprecations

• Certain unclear/ambiguous ways to write a raw language tag; these will now emit a warning in anticipation of an upcoming change to how they are parsed
• Fallback to Arabic numerals for numbering systems that do not support the number zero (e.g. for "⓵")
• Various symbols were renamed, see the deprecation section in the dedicated changelog for a full listing
• Some citation styles that were renamed or superseded
  • council-of-science-editors is now called cse-citation-sequence-brackets-8th-edition
  • council-of-science-editors-author-date is now called cse-name-year
  • modern-language-association-8 / mla-8 is superseded by modern-language-association / mla
  • vancouver is now called nlm-citation-sequence
  • vancouver-superscript is now called nlm-citation-sequence-superscript
• Undocumented array forms of enum and terms items

Removals

• The path element, use curve instead (Breaking change)

• The pdf.embed element, use pdf.attach instead (Breaking change)
• The scoped functions cbor.decode, csv.decode, json.decode, toml.decode, xml.decode, yaml.decode, and image.decode; directly pass bytes to the top-level functions instead (Breaking change)
• Various previously deprecated symbols, see the removals section in the dedicated changelog for a full listing (Breaking change)

Development

• The typst-kit crate was completely reworked to make it easier to create a Typst World implementation
• Diagnostic hints can now have spans (though typically they will be detached, which just means there isn't a span)
• Increased minimum supported Rust version to 1.92
• Moved Nix flake from typst/typst to typst/typst-flake, where it is now maintained by the community as a best effort
