Version 0.9.0 (October 31, 2023)

Bibliography management

New bibliography engine based on CSL (Citation Style Language). Ships with about 100 commonly used citation styles and can load custom .csl files.
Added new form argument to the cite function to produce different forms of citations (e.g. for producing a citation suitable for inclusion in prose)
The cite function now takes only a single label/key instead of allowing multiple. Adjacent citations are merged and formatted according to the citation style's rules automatically. This works both with the reference syntax and explicit calls to the cite function. (Breaking change)
The cite function now takes a label instead of a string (Breaking change)
Added full argument to bibliography function to print the full bibliography even if not all works were cited
Bibliography entries can now contain Typst equations (wrapped in $..$ just like in markup), this works both for .yml and .bib bibliographies
The hayagriva YAML format was improved. See its changelog for more details. (Breaking change)
A few bugs with .bib file parsing were fixed
Removed brackets argument of cite function in favor of form

Visualization

Gradients and colors (thanks to @Dherse)
- Added support for gradients on shapes and text
- Supports linear, radial, and conic gradients
- Added support for defining colors in more color spaces, including Oklab, Linear RGB(A), HSL, and HSV
- Added saturate, desaturate, and rotate functions on colors
- Added color.map module with predefined color maps that can be used with gradients
- Rename kind function on colors to space
- Removed to-rgba, to-cmyk, and to-luma functions in favor of a new components function
Improved rendering of rectangles with corner radius and varying stroke widths
Added support for properly clipping boxes and blocks with a border radius
Added background parameter to overline, underline, and strike functions
Fixed inaccurate color embedding in PDFs
Fixed ICC profile handling for images embedded in PDFs

Text and Layout

Added support for automatically adding proper spacing between CJK and Latin text (enabled by default)
Added support for automatic adjustment of more CJK punctuation
Added quote element for inserting inline and block quotes with optional attributions
Added raw.line element for customizing the display of individual lines of raw text, e.g. to add line numbers while keeping proper syntax highlighting
Added support for per-side inset customization to table function
Added Hungarian and Romanian translations
Added support for Czech hyphenation
Added support for setting custom smart quotes
The default figure separator now reacts to the currently set language and region
Improved line breaking of links / URLs (especially helpful for bibliographies with many URLs)
Improved handling of consecutive hyphens in justification algorithm
Fixed interaction of justification and hanging indent
Fixed a bug with line breaking of short lines without spaces when justification is enabled
Fixed font fallback for hyphen generated by hyphenation
Fixed handling of word joiner and other no-break characters during hyphenation
Fixed crash when hyphenating after an empty line
Fixed line breaking of composite emoji like 🏳️‍🌈
Fixed missing text in some SVGs
Fixed font fallback in SVGs
Fixed behavior of to argument on pagebreak function
Fixed set align(..) for equations
Fixed spacing around placed elements
Fixed coalescing of above and below spacing if given in em units and the font sizes differ
Fixed handling of extent parameter of underline, overline, and strike functions
Fixed crash for floating placed elements with no specified vertical alignment
Partially fixed a bug with citations in footnotes

Math

Added gap argument for vec, mat, and cases function
Added size argument for abs, norm, floor, ceil, and round functions
Added reverse parameter to cases function
Added support for multinomial coefficients to binom function
Removed rotation argument on cancel function in favor of a new and more flexible angle argument (Breaking change)
Added wide constant, which inserts twice the spacing of quad
Added csch and sech operators
↼, ⇀, ↔, and ⟷ can now be used as accents
Added integral.dash, integral.dash.double, and integral.slash symbols
Added support for specifying negative indices for augmentation lines to position the line from the back
Fixed default color of matrix augmentation lines
Fixed attachment of primes to inline expressions
Math content now respects the text baseline setting

Performance

Fixed a bug related to show rules in templates which would effectively disable incremental compilation in affected documents
Micro-optimized code in several hot paths, which brings substantial performance gains, in particular in incremental compilations
Improved incremental parsing, which affects the whole incremental compilation pipeline
Added support for incremental parsing in the CLI
Added support for incremental SVG encoding during PDF export, which greatly improves export performance for documents with many SVG

Tooling and Diagnostics

Improved autocompletion for variables that are in-scope
Added autocompletion for package imports
Added autocompletion for labels
Added tooltip that shows which variables a function captures (when hovering over the equals sign or arrow of the function)
Diagnostics are now deduplicated
Improved diagnostics when trying to apply unary + or - to types that only support binary + and -
Error messages now state which label or citation key isn't present in the document or its bibliography
Fixed a bug where function argument parsing errors were shadowed by function execution errors (e.g. when trying to call array.sorted and passing the key function as a positional argument instead of a named one).

Export

Added support for configuring the document's creation date. If the date is set to auto (the default), the PDF's creation date will be set to the current date and time.
Added support for configuring document keywords
Generated PDFs now contain PDF document IDs
The PDF creator tool metadata now includes the Typst version

Web app

Added version picker to pin a project to an older compiler version (with support for Typst 0.6.0+)
Fixed desyncs between editor and compiler and improved overall stability
The app now continues to highlight the document when typing while the document is being compiled

Command line interface

Added support for discovering fonts through fontconfig
Now clears the screen instead of resetting the terminal
Now automatically picks correct file extension for selected output format
Now only regenerates images for changed pages when using typst watch with PNG or SVG export

Miscellaneous Improvements

Added version type and sys.version constant specifying the current compiler version. Can be used to gracefully support multiple versions.
The U+2212 MINUS SIGN is now used when displaying a numeric value, in the repr of any numeric value and to replace a normal hyphen in text mode when before a digit. This improves, in particular, how negative integer values are displayed in math mode.
Added support for specifying a default value instead of failing for remove function in array and dictionary
Simplified page setup guide examples
Switched the documentation from using the word "hashtag" to the word "hash" where appropriate
Added support for array.zip without any further arguments
Fixed crash when a plugin tried to read out of bounds memory
Fixed crashes when handling infinite lengths
Fixed introspection (mostly bibliography) bugs due to weak page break close to the end of the document
