v7.0.0

7.0.0 (2026-07-13)

• feat!: default to Matrix buffers with optional backing array type (dfd1e97)

Bug Fixes

• require PipeChannels 1.0.1 for the iterate/close race fix (a49755e)
• store matching buffers by reference in put! (zero-copy) (502e88b)

BREAKING CHANGES

• SignalChannel is now SignalChannel{T,N,M}; the default eltype
  is Matrix{T} instead of FixedSizeMatrixDefault{T}. Code relying on take!
  returning a FixedSizeMatrixDefault must construct channels with the explicit
  backing type SignalChannel{T,N,FixedSizeMatrixDefault{T}} or adapt to Matrix{T}.

v6.2.2

6.2.2 (2026-02-17)

Bug Fixes

• return input channel directly when rechunk size matches (89f2ba6)

v6.2.1

6.2.1 (2026-02-10)

Bug Fixes

• use eager value reading in channel_combine tests (92dae31)

v6.2.0

6.2.0 (2026-02-10)

Features

• add mux and add functions for combining SignalChannels (83a47fb)

v6.1.0

6.1.0 (2026-01-23)

Features

• add Val{N} parameter to tee for N-way channel splitting (38a9f0a)

v6.0.0

6.0.0 (2026-01-08)

• refactor!: make SignalChannel{T,N} with compile-time channel count (afdebd7)

Bug Fixes

• update soapysdr_ext.jl test to use new SignalChannel{T,N} API (ebd2b52)

Features

• integrate rechunk into stream_data for flexible chunk sizes (b385343)

BREAKING CHANGES

• SignalChannel API changed from runtime to compile-time
  channel count parameter.

Before: SignalChannel{T}(num_samples, num_channels, buffer_size)
After: SignalChannel{T,N}(num_samples, buffer_size)

This enables:

• Zero-allocation rechunking via compile-time loop unrolling
• Full type specialization throughout the signal processing pipeline
• ~2000 M samples/s throughput in benchmarks

Changes:

• SignalChannel{T} now defaults to SignalChannel{T,1}
• Added num_antenna_channels(chan) accessor function
• Updated RechunkState to use SignalChannel{T,N} type parameter
• Added compile-time API detection in benchmarks for backward compat
• Updated all tests and extensions for new API

v5.0.0

5.0.0 (2026-01-05)

• refactor!: use PipeChannel instead of Channel for lock-free performance (a151677)

BREAKING CHANGES

• SignalChannel now uses PipeChannel internally instead of
  Julia's built-in Channel. This provides zero-allocation performance in the
  hot path but requires exactly one producer and one consumer thread.

Changes:

• SignalChannel now wraps PipeChannel instead of Channel
• Default buffer size changed from 0 to 16 (PipeChannel requires positive capacity)
• Removed rechunk_lockfree (now redundant since rechunk is lock-free)
• Removed locking methods (lock, unlock, trylock) as PipeChannel is lock-free
• Updated all tests and benchmarks to use PipeChannel for generic channel tests
• Added PACKAGE_VERSION support in benchmarks for version-aware testing
• PipeChannel now subtypes AbstractChannel{T} for compatibility

v4.0.1

4.0.1 (2026-01-05)

Bug Fixes

• benchmark: use FixedSizeMatrixDefault to avoid put! conversion allocations (c002824)

v4.0.0

4.0.0 (2025-12-19)

• refactor!: remove put_or_close! in favor of bind for error propagation (24c4f3f)

BREAKING CHANGES

• put_or_close! is no longer exported. Use plain put!
  instead - bind() handles error propagation when downstream closes.

The put_or_close! function was redundant - bind(in, task) already
handles error propagation when a processing task fails due to a
closed downstream channel. Simplified tee, rechunk, and membuffer
to use plain put! calls.

Added test verifying that errors propagate upstream via bind when
a downstream channel is closed.
