+    function
+  - Added Hungarian and Romanian translations

+  - Fixed font fallback in SVGs
+  - Fixed `{set align(..)}` for equations
+  - Fixed spacing around [placed]($place) elements

+  - Fixed crash for [floating placed elements]($place.float) with no specified
+    vertical alignment

+- Math
+  - Added `gap` argument for [`vec`]($math.vec.gap), [`mat`]($math.mat.gap), and
+    [`cases`]($math.cases.gap) function
+  - Added `size` argument for [`abs`]($math.abs), [`norm`]($math.norm),
+    [`floor`]($math.floor), [`ceil`]($math.ceil), and [`round`]($math.round)
+    functions
+  - Added [`reverse`]($math.cases.reverse) parameter to cases function
+  - Added support for multinomial coefficients to [`binom`]($math.binom)
+    function
+  - Removed `rotation` argument on [`cancel`]($math.cancel) function in favor of
+    a new and more flexible `angle` argument (**Breaking change**)
+  - Added `wide` constant, which insert twice the spacing of `quad`
+  - `↼`, `⇀`, `↔`, and `⟷` can now be used as [accents]($math.accent)
+  - Added `integral.dash`, `integral.dash.double`, and `integral.slash`
+    [symbols]($category/symbols/sym)

+    [augmentation]($math.mat.augment) lines to position the line from the back
+  - Fixed default color of matrix [augmentation]($math.mat.augment) lines
+  - Fixed attachment of primes to inline expressions
+  - Math content now respects the [baseline]($text.baseline) configuration
+
+- Performance
+  - Fixed a bug related to show rules in templates which would effectively
+    disable incremental compilation in affected documents
+  - Micro-optimized code in several hot paths, which brings substantial
+    performance gains, in particular in incremental compilations
+  - Improved incremental parsing, which affects the whole incremental
+    compilation pipeline
+  - Added support for incremental parsing in the CLI
+  - Added support for incremental SVG encoding during PDF export, which greatly
+    improves export performance for documents with many SVG
+
+- Tooling and Diagnostics
+  - Improved autocompletion for variables that are in-scope
+  - Added autocompletion for package imports
+  - Added tooltips that show which variables a function captures
+  - Diagnostics are now deduplicated
+
+- Command line interface
+  - Now clears the screen instead of resetting the terminal
+  - Now automatically picks correct file extension for selected output format
+  - Now only regenerates images for changed pages when using `typst watch` with
+    PNG or SVG export
+
+- Miscellaneous Improvements
+  - Added `sys.version` specifying the current compiler version. Can be used to
+    gracefully support multiple versions.
+  - The U+2212 MINUS SIGN is now used when displaying a numeric value, in the
+    [`repr`]($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 configuring document [`keywords`]($document.keywords) and
+    the document's creation [`date`]($document.date)
+  - PDF creator tool metadata now includes the Typst version
+  - Added support for specifying a default value instead of failing for
+    [`remove`] function in [array]($array.remove) and
+    [dictionary]($dictionary.remove)
+  - Simplified page setup guide examples
+  - Switched the documentation from using the word "hashtag" to the word "hash"
+    where appropriate
+  - Fixed crash when a plugin tried to read out of bounds memory
+  - Fixed crashes when handling infinite [lengths]($length)
+  - Fixed introspection (mostly bibliography) bugs due to weak page break close
+    to the end of the document
+
+- Development
+  - Extracted `typst::ide` into separate `typst_ide` crate
+  - Removed a few remaining `'static` bounds on `&dyn World`
+  - Removed unnecessary dependency, which reduces the binary size
+  - Fixed compilation of `typst` by itself (without `typst-library`)
+
