Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

  • BLD: allow selecting arbitrary (supported) Python target ABIs at build time
  • DEP: drop support for Python 3.10, require 3.11 or newer
  • DEP: upgrade MSRV to 1.83
  • DEP: bump rust-numpy and pyo3 to 0.29
  • WHL: drop win32 support (stop distributing wheels)

0.5.3 - 2025-11-15

  • BLD: warning free builds in any configuration
  • BUG: fix bugs in time_to_next_pixel internal computation with no-default build configurations. These bugs were introduced in version 0.5.2
  • WHL: re-enable fma on manylinux x86_64 wheels, and disable branchless execution, bringing this build's configuration in line with the equivalent macos target
  • WHL: build macos-x86_64 wheels natively again, and ensure they are tested

0.5.2 - 2025-11-14

  • WHL: add support for Windows-arm64 targets
  • DOC: document stability guarantees and free-threading support
  • ENH: enable FMA for x86_64 targets on macOS and Windows (performance wasn't measured on Windows)
  • BLD: add opt-out build options for FMA and branchless optimizations
  • WHL: disable branchless execution for macOS x86_64 wheels

0.5.1 - 2025-07-18

  • BLD: fix a build-time error when building from source with maturin >=1.9 this error prevented packaging versions 0.4.0 and 0.5.0 to conda-forge

0.5.0 - 2025-07-17

  • DEP: drop support for Python 3.9, require 3.10 or newer
  • FEAT: support periodic boundaries and fine-grained boundary conditions selection

0.4.0 - 2025-07-10

  • DOC: consistently indicate argument types (positional-only and keyword-only) in rlic.convolve's docstring
  • DOC: fix invalid example code and re-generate output image
  • DOC: document memory usage
  • PERF: turn rust panics into fatal errors, improving performance and reducing binary size by 10% each
  • PERF: leverage Fused Multiply-Add (FMA) instructions on supporting architectures (including Apple Silicon and AMD processors). Except about 2 to 4% gain
  • PERF: avoid back-and-forth conversions between usize and i64 representations for image coordinates. Expect about 2% gain
  • DEP: drop support for NumPy 1.21.x, require 1.22.0 or newer
  • WHL: upgrade manylinux image from 2014 to 2_28, following NumPy

0.3.4 - 2025-04-09

  • BLD: declare compatibility with free-threaded CPython
  • DOC: fix an incomplete sentence in rlic.convolve's docstring
  • TYP: add array shape information to type hints
  • BLD: bump MSRV (1.64.0 -> 1.65.0)
  • ENH: report all exceptions instead of just the first one when validating inputs, on all supported Python versions (using the backport package exceptiongroup on 3.9 and 3.10)

0.3.3 - 2025-03-08

  • BUG: fix a typo in a user visible error message
  • ENH: report all exceptions instead of just the first one when validating inputs, on Python 3.11 and newer
  • BUG: always run all validators before returning

0.3.2 - 2025-03-07

  • DOC: prefer using a convex kernel shape in examples
  • ENH: terminate streamline integration when a NaN vector component is encountered
  • ENH: explicitly forbid non-finite values in kernel

0.3.1 - 2025-03-04

  • DOC: add example scripts and visualizations to README.md
  • ENH: allow negative values in kernels. It's still an unusual use case, but there is no strong argument for forbidding it.
  • ENH: Previously, only kernels with at least 3 elements and at most as long as the shortest dimension of the image were allowed. These restrictions are now lifted.
  • DOC: improve rlic.convolve's docstring. Add detail to the description of the texture and kernel arguments

0.3.0 - 2025-03-02

  • PERF: disable build parallelism to the benefit of runtime performance (expect about 5 to 10% gain)
  • PERF: avoid conditional branching in pixel traversal time evaluation (expect about 30 to 40% gain)
  • TST: test for regressions against reference implementation

0.2.2 - 2025-03-01

  • BUG: fix a defect in polarization mode

0.2.1 - 2025-02-27

  • BUG: fix incorrect implementation of infinite-time edge cases
  • TST: improve Rust and Python test coverage
  • TST: test against future versions of direct rust dependencies
  • BLD/TST: fix incorrect Minimal Supported Rust Version (MSRV) (bumped from 1.63 to 1.64) and check it in CI

0.2.0 - 2025-02-25

  • WHL: build and publish abi3 wheels for all platforms + architecture combos supported by NumPy as of 2.2.3
  • API: rename the first argument to rlic.convolve from image to texture, and make it positional-only.

0.1.2 - 2025-02-24

  • ENH: add support for single precision (float32) input data

0.1.1 - 2025-02-23

  • DEP: add support for numpy 1.x
  • REL: ensure source distribution is testable and enable auto-publishing

0.1.0 - 2025-02-23

This is the first release. It's missing wheels and documentation. Only source distribution is published on PyPI.
