+# CategoricalArrays.jl v1.0.0 Release Notes
+
+## Breaking changes
+
+* `unique(::CategoricalArray)` and `levels(::CategoricalArray)` return
+  a `CategoricalArray` instead of unwrapping values, consistent with
+  `unique(::AbstractArray)` in Base and `levels(::AbstractArray)` in DataAPI
+  ([#358](https://github.com/JuliaData/CategoricalArrays.jl/pull/358),
+  [#425](https://github.com/JuliaData/CategoricalArrays.jl/pull/425)).
+
+* `cut` always closes the last interval on the right
+  ([#409](https://github.com/JuliaData/CategoricalArrays.jl/pull/409)).
+
+* `cut(x, breaks)` rounds breaks to generate shorter labels
+ ([#422](https://github.com/JuliaData/CategoricalArrays.jl/pull/422)).
+
+* `cut(x, ngroups)` takes breaks from actual values instead of using
+  quantile estimates which are generally longer
+  ([#416](https://github.com/JuliaData/CategoricalArrays.jl/pull/416))
+  This only changes group labels, not their contents.
+
+* `T(::CategoricalArray{U})` and `convert(T, ::CategoricalArray{U})`
+  now consistently return an `Array{U}` for `T` in `Array`, `Vector`, `Matrix`.
+  This avoids creating `Array{<:CategoricalValue}` objects unless explicitly requested
+  ([#420](https://github.com/JuliaData/CategoricalArrays.jl/pull/420)).
+
+
+* All deprecations have been removed
+  ([#419](https://github.com/JuliaData/CategoricalArrays.jl/pull/419)).
+
+## New features
+
+* Support reading from and writing to Arrow files
+  ([#415](https://github.com/JuliaData/CategoricalArrays.jl/pull/415)).
+
+* Improve performance of `recode`
+  ([#407](https://github.com/JuliaData/CategoricalArrays.jl/pull/407)).
+
+* Support weighted quantiles in `cut`
+  ([#423](https://github.com/JuliaData/CategoricalArrays.jl/pull/423)).
+
+## Bug fixes
+
+* Fix performance regression on Julia 1.11 and above
+  ([#418](https://github.com/JuliaData/CategoricalArrays.jl/pull/418)).
+
+* Fix `cut` corner cases with duplicated breaks
+  ([#410](https://github.com/JuliaData/CategoricalArrays.jl/pull/410)).
