Perfolizer

This is a maintenance release: one pairwise-estimator bug fix plus dependency and tooling modernization. There are no public API changes, and the library keeps targeting netstandard2.0 and net6.0.

Bug Fixes

• Fix a NullReferenceException in the two-sample pairwise estimators when one sample is weighted and the other is not. The unweighted sample is now treated as having unit weights.

Dependencies

• Bump System.Memory 4.5.5 → 4.6.3 (netstandard2.0 target).

Internal

• Migrate the test suite from the deprecated xunit v2 to xunit.v3 (with Microsoft.NET.Test.Sdk 18.7, xunit.runner.visualstudio 3.1.5, coverlet.collector 10.0.1, and Verify.XunitV3).
• Adopt the .NET 10 SDK and C# 14 for the test and tooling projects; the library target frameworks are unchanged.
• Bump GitHub Actions and mise-action to their current majors.
• Clear the outstanding nullable-reference and obsolete-usage compiler warnings.
• Run the full test suite in CI, not just the core project.

Full Changelog: v0.7.2...v0.7.3

Upgrades the Pragmastat dependency to 13.0.1. No public perfolizer API changed.

Internal

• Upgrade Pragmastat from 12.0.0 to 13.0.1, migrating off the removed Probability.Half/Probability.NaN members.

Pragmastat 13.0.0 is a major release with public API changes across its bindings. If you use Pragmastat types directly alongside perfolizer, review its release notes.

Full Changelog: v0.7.1...v0.7.2

This release deprecates scale estimators and significance testing APIs in favor of their Pragmastat replacements, and upgrades the Pragmastat dependency to 12.0.0.

Deprecations

• Scale estimators: IScaleEstimator, MedianAbsoluteDeviationEstimator, QuantileAbsoluteDeviationEstimator, and ShamosEstimator are now obsolete. Migrate to Pragmastat.Estimators.SpreadEstimator.
• Significance testing: All types in Mathematics.SignificanceTesting are now obsolete, including base interfaces/classes (ISignificanceOneSampleTest, ISignificanceTwoSampleTest, IEquivalenceTest, etc.), and all implementations (BrunnerMunzelTest, WelchTest, StudentTest, SimpleEquivalenceTest, MannWhitneyTest). Migrate to Pragmastat.Toolkit.Compare1 (one-sample) or Pragmastat.Toolkit.Compare2 (two-sample).

Bug Fixes

• Resolve Threshold namespace ambiguity between Perfolizer.Metrology.Threshold and Pragmastat.Threshold introduced by the Pragmastat 12.0.0 upgrade.

Internal

• Upgrade Pragmastat dependency from 11.1.0 to 12.0.0.
• Suppress obsolete warnings in internal types (DoubleMadOutlierDetector, MadOutlierDetector, GammaEffectSizeFunction) and test files that still exercise deprecated APIs.

Breaking Changes

• Upgraded Pragmastat dependency from 10.0.0 to 11.1.0; several adapter changes were required:
  • MeasurementUnit constructor now requires a family parameter; updated FrequencyUnit, SizeUnit, PercentUnit, TimeUnit
  • NumberUnit/RatioUnit/DisparityUnit subclasses removed; use MeasurementUnit.Number/.Ratio/.Disparity static fields instead
  • NumberValue/RatioValue/DisparityValue wrappers removed; ToThreshold(double) replaces ToThreshold(NumberValue)
  • AbbreviationAscii removed; use Abbreviation everywhere
  • UnitPresentation parameter dropped from MeasurementFormatter.Format
  • SampleFormatter/MeasurementFormatter/MeasurementUnitFormatter base classes removed; PerfolizerMeasurementFormatter, PerfolizerMeasurementUnitFormatter, and PerfolizerSampleFormatter rewritten as standalone classes
  • Estimator.Estimate() now returns Measurement instead of double
  • TimeUnit.Microsecond abbreviation changed from μs to us
• ShamosEstimator is now marked [Obsolete]; use SpreadEstimator instead

Improvements

• ShamosEstimator now delegates its raw spread computation to SpreadEstimator (backed by FastSpread), replacing an O(n²) pairwise helper with an O(n log n) implementation; bias correction factors are preserved

Internal

• Removed LocationEstimatorSimulation and EfficiencySimulation; this coverage is provided by pragmastat's own Rust simulation (rs:sim avg-drift)
• CI workflow now triggers on all branches

Full Changelog: v0.6.7...v0.7.0

Release notes generated by herald v1.0.4

Breaking Changes

• Upgraded Pragmastat dependency from 8.0.0 to 10.0.0 with the following migration changes:
  • Rng.Uniform() and Rng.Uniform(a,b) renamed to UniformDouble() and UniformDouble(a,b)
  • Probability.Median replaced with Probability.Half (alias removed)

Internal

• Removed a Measurement-level round-trip test case for "16x" values due to an undocumented breaking change in Pragmastat v10.0.0 where RatioUnit.Abbreviation changed from "x" to ""

Full Changelog: v0.6.6...v0.6.7

Dependency maintenance release: upgrades Pragmastat from 7.0.0 to 8.0.0.

Internal

• Upgrade Pragmastat dependency from 7.0.0 to 8.0.0 (major version bump with no code changes required)

Full Changelog: v0.6.5...v0.6.6

Release notes generated by herald v1.0.4

Modernize build infrastructure: migrate from Cake Frosting to mise, replace CI/CD workflows with tiered pipelines, and bump Pragmastat to 7.0.0.

Breaking Changes

• Pragmastat dependency upgraded from 6.0.1 to 7.0.0 (major version bump)

Improvements

• Migrate build system from Cake Frosting to mise tasks (build, test, check, clean, restore, pack, ci)
• Version now read from a single VERSION file instead of hardcoded MSBuild properties in Directory.Build.props
• Replace GitHub Actions workflows (build.yml, publish-nightly.yml, publish-release.yml) with tiered ci.yml (format check, cross-platform test matrix, pack, gate) and manual publish.yml (test, pack, tag, GitHub release, NuGet push)
• Remove nightly MyGet publishing
• Apply dotnet format whitespace fixes across 121 files
• Remove deprecated PackageIconUrl from package metadata (icon already embedded via PackageIcon)

Documentation

• Rewrite README project description with three paragraphs covering Perfolizer's purpose, BenchmarkDotNet origins, and Pragmastat migration
• Update README badges: remove MyGet and CI badge, update build badge URL

Internal

• Delete Cake Frosting build project (build/), shell scripts (build.sh, build.ps1, build.bat)
• Clean up .gitignore: remove Mercurial directives, BenchmarkDotNet leftovers, Cake entries, and legacy C++ patterns; add nupkg/
• Update branch references from master to main in CI workflow and package metadata

Full Changelog: v0.6.4...v0.6.5

Release notes generated by herald v1.0.3

A maintenance release that updates the Pragmastat dependency to v6.0.1 and removes redundant code.

Internal

• Dependency update: Bumped Pragmastat from 5.2.0 to 6.0.1, which includes a redesigned ratio estimator using geometric interpolation and a new RatioBounds estimator
• Code cleanup: Removed redundant RngExtensions class as Pragmastat.Randomization.Rng now provides the Uniform(double min, double max) method directly

Full Changelog: v0.6.3...v0.6.4
