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

Unreleased

• restore the README's Synopsis and Examples sections: a quick-start recipe plus real-world examples (primitive-union dispatch, a fallback, a property union narrowed by the tagged-union matcher, and a widening variant)
• document the public API in the README: the four factories, when to use each, what the W (widening) suffix means, and examples that bind the handler-map function once
• add TSDoc to the four public matcher factories

0.8.1 - 2026-09-23

• gate CI at 100% coverage: test:ci runs c8 with --all --100 over src/, and a test loads the index.ts barrel so it is measured
• pin the duplicate-tag union collapse (members sharing a tag dispatch through one handler) with tests

0.8.0 - 2026-09-23

• reject a universe that mixes a literal with a broad type (e.g. "a" | \x-${number}``), which the finite-literal gate let through
• narrow the tagged-union matcher's handler parameters for a union-valued or optional discriminant, and its fallback to the unhandled tags, instead of passing never

0.7.1 - 2026-09-23

• upgrade dependencies

0.7.0 - 2026-09-23

• reject broad universes (string, number, template literals) and value/stringification collisions (true | "true", 1 | "1") at the factory
• type handler parameters by the matched member, so a standalone "true" universe is typed "true" rather than true

0.6.0 - 2026-09-22

• add getTaggedUnionMatcher / getTaggedUnionMatcherW for discriminated unions
• rename the primitive matcher to primitive-union: getMatcher / getMatcherW → getPrimitiveUnionMatcher / getPrimitiveUnionMatcherW, and src/primitive.ts / src/primitive.test.ts → src/primitive-union.*

0.5.0 - 2026-09-21

• reject a fallback when the handler map already covers the universe
• allow boolean, null and undefined in the matcher universe

0.4.0 - 2026-09-20

• move the _ fallback out of handlers

0.3.0 - 2026-09-18

• condensed primitive matcher factories down to 2 from formerly 4
• house shared test helpers under src/util/__tests__/

0.2.0 - 2026-09-16

• allow ternaries and lowercase comments in oxlint
• switch src/primitive.ts prose from block comments to line comments
• remove the template's match/P example modules and their documentation, and point src/index.ts at the primitive matchers

0.1.8 - 2026-09-16

• upgrade dependencies
• ignore @types/node in maintain:outdated (misleading latest dist-tag)
• require extremely concise prose in development/

0.1.7 - 2026-09-16

• require a short summary under [Unreleased] in the changelog before a branch is finished
• let create:branch start from a main that is ahead of its upstream, so a finished merge no longer blocks the next branch until it is pushed

0.1.6 - 2026-09-15

• restructure the documentation: README.md for users, CONTRIBUTING.md for contributors, and development/ for the decisions, rejected alternatives and known issues
• document the decisions and known issues for CI, tooling, testing, publishing and the workflow

0.1.5 - 2026-09-15

• improve CI configuration

0.1.4 - 2026-09-14

• fix CI to node from custom image
• upgrade dependencies

0.1.3 - 2026-09-14

• change to custom image for CI

0.1.2 - 2026-09-14

0.1.1 - 2026-09-14

0.1.0 - 2026-09-14
