CategoricalArrays v1.0.0

Diff since v0.10.8

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, #425).

• cut always closes the last interval on the right (#409).

• cut(x, breaks) rounds breaks to generate shorter labels (#422).

• cut(x, ngroups) takes breaks from actual values instead of using quantile estimates which are generally longer (#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).

• All deprecations have been removed (#419).

New features

• Support reading from and writing to Arrow files (#415).

• Improve performance of recode (#407).

• Support weighted quantiles in cut (#423).

Bug fixes

• Fix performance regression on Julia 1.11 and above (#418).

• Fix cut corner cases with duplicated breaks (#410).
