# Version 0.8.0 (September 13, 2023)

## Scripting
- Plugins (thanks to [@astrale-sharp](https://github.com/astrale-sharp) and
  [@arnaudgolfouse](https://github.com/arnaudgolfouse))
  - Typst can now load [plugins]($plugin) that are compiled to WebAssembly
  - Anything that can be compiled to WebAssembly can thus be loaded as a plugin
  - These plugins are fully encapsulated (no access to file system or network)
  - Plugins can be shipped as part of [packages]($scripting/#packages)
  - Plugins work just the same in the web app
- Types are now first-class values **(Breaking change)**
  - A [type] is now itself a value
  - Some types can be called like functions (those that have a constructor),
    e.g. [`int`] and [`str`]
  - Type checks are now of the form `{type(10) == int}` instead of the old
    `{type(10) == "integer"}`. [Compatibility]($type/#compatibility) with the
    old way will remain for a while to give package authors time to upgrade, but
    it will be removed at some point.
  - Methods are now syntax sugar for calling a function scoped to a type,
    meaning that `{"hello".len()}` is equivalent to `{str.len("hello")}`
- Added support for [`import`]($scripting/#modules) renaming with `as`
- Added a [`duration`] type
- Added support for [CBOR]($cbor) encoding and decoding
- Added encoding and decoding functions from and to bytes for data formats:
  [`json.decode`]($json.decode), [`json.encode`]($json.encode), and similar
  functions for other formats
- Added [`array.intersperse`]($array.intersperse) function
- Added [`str.rev`]($str.rev) function
- Added `calc.tau` constant
- Made [bytes] joinable and addable
- Made [`array.zip`]($array.zip) function variadic
- Fixed bug with [`eval`] when the `mode` was set to `{"math"}`
- Fixed bug with [`ends-with`]($str.ends-with) function on strings
- Fixed bug with destructuring in combination with break, continue, and return
- Fixed argument types of [hyperbolic functions]($calc.cosh), they don't allow
  angles anymore **(Breaking change)**
- Renamed some color methods: `rgba` becomes `to-rgba`, `cmyk` becomes
  `to-cmyk`, and `luma` becomes `to-luma` **(Breaking change)**

## Export
- Added SVG export (thanks to [@Enter-tainer](https://github.com/Enter-tainer))
- Fixed bugs with PDF font embedding
- Added support for page labels that reflect the
  [page numbering]($page.numbering) style in the PDF

## Text and Layout
- Added [`highlight`] function for highlighting text with a background color
- Added [`polygon.regular`]($polygon.regular) function for drawing a regular
  polygon
- Added support for tabs in [`raw`] elements alongside
  [`tab-width`]($raw.tab-size) parameter
- The layout engine now tries to prevent "runts" (final lines consisting of just
  a single word)
- Added Finnish translations
- Added hyphenation support for Polish
- Improved handling of consecutive smart quotes of different kinds
- Fixed vertical alignments for [`number-align`]($page.number-align) argument on
  page function **(Breaking change)**
- Fixed weak pagebreaks after counter updates
- Fixed missing text in SVG when the text font is set to "New Computer Modern"
- Fixed translations for Chinese
- Fixed crash for empty text in show rule
- Fixed leading spaces when there's a linebreak after a number and a comma
- Fixed placement of floating elements in columns and other containers
- Fixed sizing of block containing just a single box

## Math
- Added support for [augmented matrices]($math.mat.augment)
- Removed support for automatic matching of fences like `|` and `||` as
  there were too many false positives. You can use functions like
  [`abs`]($math.abs) or [`norm`]($math.norm) or an explicit [`lr`]($math.lr)
  call instead. **(Breaking change)**
- Fixed spacing after number with decimal point in math
- Fixed bug with primes in subscript
- Fixed weak spacing
- Fixed crash when text within math contains a newline

## Tooling and Diagnostics
- Added hints when trying to call a function stored in a dictionary without
  extra parentheses
- Fixed hint when referencing an equation without numbering
- Added more details to some diagnostics (e.g. when SVG decoding fails)

## Command line interface
- Added `typst update` command for self-updating the CLI
  (thanks to [@jimvdl](https://github.com/jimvdl))
- Added download progress indicator for packages and updates
- Added `--format` argument to explicitly specify the output format
- The CLI now respects proxy configuration through environment variables and has
  a new `--cert` option for setting a custom CA certificate
- Fixed crash when field wasn't present and `--one` is passed to `typst query`

## Miscellaneous Improvements
- Added [page setup guide]($guides/page-setup-guide)
- Added [`figure.caption`]($figure.caption) function that can be used for
  simpler figure customization (**Breaking change** because `it.caption` now
  renders the full caption with supplement in figure show rules and manual
  outlines)
- Moved `caption-pos` argument to `figure.caption` function and renamed it to
  `position` **(Breaking change)**
- Added [`separator`]($figure.caption.separator) argument to `figure.caption`
  function
- Added support for combination of and/or and before/after
  [selectors]($selector)
- Packages can now specify a
  [minimum compiler version](https://github.com/typst/packages#package-format)
  they require to work
- Fixed parser bug where method calls could be moved onto their own line for
  `[#let]` expressions in markup **(Breaking change)**
- Fixed bugs in sentence and title case conversion for bibliographies
- Fixed supplements for alphanumeric and author-title bibliography styles
- Fixed off-by-one error in APA bibliography style

## Development
- Made `Span` and `FileId` more type-safe so that all error conditions must be
  handled by `World` implementors
