+## 0.9.2 (pending)
+
+* Let `braket()` take an optional third argument to render `braket(u,A,v)` as
+`⟨u|A|v⟩`. The one argument case `braket(a)` is still rendered as `⟨a|a⟩` and
+the two argument case `braket(u,v)` is still rendered as `⟨u|v⟩`.
+* Let `expval()` take an optional second argument to render `expval(A,a)` as
+`⟨a|A|a⟩`. The one argument case `expval(A)` is still rendered as `⟨A⟩`.
+* **(breaking)** Differentiated big-O `Order(...)` and little-o `order(...)`.
+* Let Taylor series term `taylorterm(...)` automatically add parenthesis, so
+that e.g. `tarlorterm(f,x,1+a,n-1)`'s `1+a` and `n-1` can be put inside
+parenthesis when needed.
+* Fixed a rendering issue of `Set(...)` when it contains tall contents.
+* Removed the `box(..)` layer from `tensor(...)`'s phantom index.
+* Added 2D and 3D rotation matrix `rot2mat(...)` and `rot3mat(...)`.
+* Added Gram matrix `grammat(...)`.
+* Removed `gradient` and `divergence`, since most users will use the abbreviated
+names `grad` and `div`. This prevents name collisions when users do wildcard
+importing, especially with Typst's built-in `gradient` that shows color
+gradients on texts.
+
+## 0.9.1
+
+* Added show rules `super-T-as-transpose` and `super-plus-as-dagger`, so that
+`..^T` and `..^+` can be rendered as a transpose operator and a dagger
+(i.e. conjugate transpose) operator, respectively, just like handwriting.
+* Adjusted spacing for `dd()`, following advice in TeXBook Chapter 18. The
+intra spacing can be disabled by a new optional argument `compact:#true`.
+* Fixed a spacing issue of `vecrow(..)`.
+* **(breaking)** Let `iprod(..)` be rendered in the more familiar inner
+product `⟨a,b⟩`, instead of `⟨a|b⟩`--that can be done with `braket(a,b)`.
+* Added optional argument `big:#true` to Jacobian matrix and Hessian matrix, so
+that the fractions can be rendered in an "uncramped" form. The default is the
+"cramped" form just like LaTeX.
+* Added `taylorterm(...)` to display terms in the Taylor series.
+
+## 0.9.0
+
+Changed the minimum Typst version to 0.10.0.
+
+* Fixed the appearance of `braket`, `ketra`, and `mel`.
+* Fixed Hessian matrix `hmax(...)`.
+
+## 0.8.1
+
+## 0.8.0
+
+* Added CI.
+* **(breaking)** Let `va(...)` (vector arrow) be not bold, according to the ISO
+standard.
+
+## 0.7.5
+
+* First appeared in the official package collection
+[typst/packages](https://github.com/typst/packages).
+
+## 0.7.4
+
+* Renamed from `physics` to `physica`, meaning _natural sciences_.
