Prepares the 1.3.0 release.

Why 1.3.0

The unreleased changes add features (problem details, retry policy, exception handler, compression, authentication, new host and client options), so a patch release is out. The public API compared with the 1.2.1 tag has only additions, so code compiled against 1.2.1 keeps working. Several changes alter behaviour, but each makes an already-wrong setup fail earlier or tightens an edge case; they are marked in the changelog rather than treated as a major version.

Changes

• CHANGELOG.md: [Unreleased] becomes [1.3.0] - 2026-10-11, with a new empty [Unreleased] above it and updated compare links.
• CHANGELOG.md: [Fix] Answer only request-format violations with 400 (ArgusProtocolException) #63, [Fix] Percent-encode routes and validate header names and values #69, [Fix] Validate route templates at registration (#41) #73, [Fix] Negotiate the response serializer from the Accept header (#42) #75, [Feature] Return problem details from the host's built-in 400/406/503 responses (#53) #77 and [Feature] Validate the protocol version in request and status lines (#52) #81 now start with **Behavior change:** and say what changes. The [Fix] Negotiate the response serializer from the Accept header (#42) #75 line also records that a new ArgusRequest no longer sets Accept: text/plain, which was not mentioned before.
• ArgusTransfer.csproj: Version is 1.3.0 and PackageReleaseNotes is written from the changelog section. The README restructure ([Update] Restructure README into a landing page with a getting-started guide #61) and the file header corrections ([Fix] Correct stale file headers and Argus Health wording, add a header check (#58) #83) are left out of the package notes because they do not affect the package's behaviour.

CITATION.cff is not changed here; the release workflow updates it.

Verification

• dotnet build ArgusTransfer.sln -warnaserror: 0 warnings, 0 errors
• dotnet test ArgusTransfer.sln: 723 passed
• dotnet format ArgusTransfer.sln --verify-no-changes: no changes
• dotnet pack produces ArgusTransfer.1.3.0.nupkg

Before releasing

If the release is cut on a later day, change the date in the changelog heading.
