v2.0.0

PeriodicArrays v2.0.0

Diff since v1.1.1

Breaking changes:

• PeriodicArray type signature: {T,N,A,F} → {T,N,A,F,G} (adds imap type param G)
• Internal field renamed from .map to .fmap; new .imap field added
• Source split into types.jl, indexing.jl, broadcast.jl, vector_interface.jl,
  repeat.jl, circshift.jl, reverse.jl, mapped_ref.jl

New features:

• PeriodicArray now accepts an explicit imap for setindex! (defaults to
  NegatedShiftMap(fmap) when omitted, preserving previous behaviour)
• New MappedRef type and mapped_ref(arr, I...) for lazy mutable out-of-bounds
  element access, fixing iterated mutation (e.g. x[i][j] = v)

v1.1.1

PeriodicArrays v1.1.1

Diff since v1.1.0

• Replaces Broadcast.ArrayStyle{PeriodicArray{T,N,A,F}} with a new PeriodicArrayStyle{N} <: AbstractArrayStyle{N} carrying dimensionality with proper style promotion rules.
• Adds _find_pa helper to recover the PeriodicArray (and its .map) from anywhere in a broadcast argument tree, fixing the fragile bc.args[1].map assumption.
• Fixes scalar-first broadcasts (1 .+ pa), mixed-element-type PA operations, and PA-with-plain-array broadcasts that previously errored or silently returned a plain Array.
• Bumps version to 1.1.1 (bug fix).
