<contributors from="v0.11.0" to="v0.11.1" />

- Tables (thanks to [PgBiel](https://github.com/PgBiel))
- Tables are now _much_ more flexible, read the new
[table guide]($guides/table-guide) to get started
- Added [`table.cell`] element for per-cell configuration
- Cells can now span multiple [columns]($table.cell.colspan) or
[rows]($table.cell.rowspan)
- The [stroke]($table.cell.stroke) of individual cells can now be customized
- The [`align`]($table.align) and [`inset`]($table.inset) arguments of the
table function now also take `{(x, y) => ..}` functions
- Added [`table.hline`] and [`table.vline`] for convenient line customization
- Added [`table.header`] element for table headers that repeat on every page
- Added [`table.footer`] element for table footers that repeat on every page
- All the new table functionality is also available for [grids]($grid)
- Fixed gutter-related bugs

- Templates
- You can now use template packages to get started with new projects. Click
_Start from template_ on the web app's dashboard and choose your preferred
template or run the `typst init <template>` command in the CLI. You can
[browse the available templates here]($universe/search/?kind=templates).
- Switching templates after the fact has become easier. You can just import a
styling function from a different template package.
- Package authors can now submit their own templates to the
[package repository](https://github.com/typst/packages). Share a template
for a paper, your institution, or an original work to help the community get
a head start on their projects.
- Templates and packages are now organized by category and discipline. Filter
packages by either taxonomy in the _Start from template_ wizard. If you are
a package author, take a look at the new documentation for
[categories](https://github.com/typst/packages/blob/main/CATEGORIES.md) and
[disciplines](https://github.com/typst/packages/blob/main/DISCIPLINES.md).

- Context
- Added _context expressions:_ Read the chapter on [context] to get started
- With context, you can access settable properties, e.g. `{context text.lang}`
to access the language set via `{set text(lang: "..")}`
- The following existing functions have been made contextual: [`query`],
[`locate`], [`measure`], [`counter.display`], [`counter.at`],
[`counter.final`], [`state.at`], and [`state.final`]
- Added contextual methods [`counter.get`] and [`state.get`] to retrieve the
value of a counter or state in the current context
- Added contextual function [`here`] to retrieve the [location] of the current
context
- The [`locate`] function now returns the location of a selector's unique
match. Its old behavior has been replaced by context expressions and only
remains temporarily available for compatibility.
- The [`counter.at`] and [`state.at`] methods are now more flexible: They
directly accept any kind of [locatable]($location/locatable) selector with
a unique match (e.g. a label) instead of just locations
- When context is available, [`counter.display`] now directly returns the
result of applying the numbering instead of yielding opaque content. It
should not be used anymore without context. (Deprecation planned)
- The [`state.display`] function should not be used anymore, use [`state.get`]
instead (Deprecation planned)
- The `location` argument of [`query`], [`counter.final`], and
[`state.final`] should not be used anymore (Deprecation planned)
- The [`styles`]($measure.styles) argument of the `measure` function should
not be used anymore (Deprecation planned)
- The [`style`] function should not be used anymore, use context instead
(Deprecation planned)
- The correct context is now also provided in various other places where it is
available, e.g. in show rules, layout callbacks, and numbering functions
in the outline

- Styling
- Fixed priority of multiple [show-set rules]($styling/show-rules): They now
apply in the same order as normal set rules would
- Show-set rules on the same element
(e.g. `{show heading.where(level: 1): set heading(numbering: "1.")}`) now
work properly
- Setting properties on an element within a transformational show rule (e.g.
`{show heading: it => { set heading(..); it }}`) is **not** supported
anymore (previously it also only worked sometimes); use show-set rules
instead (**Breaking change**)
- Text show rules that match their own output now work properly
(e.g. `` {show "cmd": `cmd`} ``)
- The elements passed to show rules and returned by queries now contain all
fields of their respective element functions rather than just specific ones
- All settable properties can now be used in [where]($function.where)
selectors
- [And]($selector.and) and [or]($selector.or) selectors can now be used with
show rules
- Errors within show rules and context expressions are now ignored in all but
the last introspection iteration, in line with the behavior of the old
[`locate`]
- Fixed a bug where document set rules were allowed after content

- Layout
- Added `reflow` argument to [`rotate`]($rotate) and [`scale`]($scale) which
lets them affect the layout

properly

block for just itself

counter update) directly at the start of a paragraph

- Fixed Finnish translation of "Listing"
- Fixed Z-ordering of multiple text decorations (underlines, etc.)
- Fixed a bug due to which text [features]($text.features) could not be
overridden in consecutive set rules

- Model
- Added [`depth`]($heading.depth) and [`offset`]($heading.offset) arguments to
heading to increase or decrease the heading level for a bunch of content;
the heading syntax now sets `depth` rather than `level`
(**Breaking change**)
- List [markers]($list.marker) now cycle by default
- The [`quote`] function now more robustly selects the correct quotes based on
language and nesting

- 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

angles anymore (**Breaking change**)

`to-cmyk`, and `luma` becomes `to-luma` (**Breaking change**)

polygon

call instead. (**Breaking change**)
- Fixed spacing after number with decimal point in math
- Fixed bug with primes in subscript

(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

- Miscellaneous Improvements
- Added [page setup guide]($guides/page-setup-guide)

simpler figure customization (**Breaking change** because `it.caption` now
renders the full caption with supplement in figure show rules and manual

- Fixed supplements for alphanumeric and author-title bibliography styles
- Fixed off-by-one error in APA bibliography style

- Development

- Added `typst query` subcommand to execute a
[query]($reference/meta/query/command-line-queries) on the command line
- The `--root` and `--font-paths` arguments cannot appear in front of the
command anymore (**Breaking change**)
