Code Review - PR #585

This PR correctly prepares the release notes and public API surface for v5.0.0. The changes are well-structured and follow the project's release management conventions.

Summary of Changes

1. CHANGELOG.md ✅

• Updated header from "Unreleased changes" to "v5.0.0" with proper version comparison link
• Added 6 missing contributor references (alphabetically sorted):
  • @Chris-Wolfgang
  • @dependabot (app link)
  • @magneticflux-
  • @robertmclaws
  • @sensslen
  • @tlogik

2. PublicAPI.Shipped.txt ✅

• Moved 165 source generation API entries from Unshipped to Shipped
• All entries are from the McMaster.Extensions.CommandLineUtils.SourceGeneration namespace
• Entries cover the complete source generation system:
  • Metadata classes: ArgumentMetadata, CommandMetadata, OptionMetadata, etc.
  • Provider interfaces: ICommandMetadataProvider, IMetadataResolver
  • Handler interfaces: IExecuteHandler, IValidateHandler, IValidationErrorHandler
  • Factory interfaces: IModelFactory
  • Registry: CommandMetadataRegistry
  • Resolver: DefaultMetadataResolver

3. PublicAPI.Unshipped.txt ✅

• Confirmed empty (only contains #nullable enable)
• All APIs correctly moved to Shipped

4. Hosting.CommandLine/releasenotes.props ✅

• Added v5.0.0 release notes with proper XML escaping (< for <)
• Documents breaking changes: dropped .NET Standard 2 and < .NET 6 support
• Notes dependency updates to latest .NET 8 libraries
• Proper version prefix condition check

Verification

All changes align with the release preparation requirements:

• ✅ Public APIs properly transitioned from Unshipped to Shipped
• ✅ CHANGELOG header updated to v5.0.0
• ✅ All contributors properly credited
• ✅ Release notes added for both packages
• ✅ Conventional commit format used: chore: prepare release notes and public API for v5.0.0

Recommendation

LGTM - This PR is ready to merge. All changes are correct and follow the project conventions outlined in CLAUDE.md.

The only remaining validation is to run ./build.ps1 as noted in the test plan to ensure no breaking changes were introduced, but given the nature of these changes (documentation and API surface tracking only), no issues are expected.
