CHDSharp v1.6.0 - What's New

Released: 2026-10-29 - Full changelog - NuGet

CHDSharp v1.6.0 is a reliability and supply-chain release: read-ahead teardown no longer blocks on
in-flight I/O, truncated CD sources report exactly where the layout ran out, and the repository
gained a full CI gate with CodeQL, Dependency Review, OpenSSF Scorecard, Dependabot, NuGet audit,
SHA-pinned actions and provenance-attested release assets.

Platform Bundle
Windows x64 CHDSharp_win-x64_v1.6.0.zip
Windows ARM64 CHDSharp_win-arm64_v1.6.0.zip
Linux x64 CHDSharp_linux-x64_v1.6.0.zip
Linux ARM64 CHDSharp_linux-arm64_v1.6.0.zip
macOS Intel CHDSharp_osx-x64_v1.6.0.zip
macOS Apple Silicon CHDSharp_osx-arm64_v1.6.0.zip

Every bundle contains a framework-dependent single-file CHDSharp / CHDSharp.exe
build (the .NET runtime is not embedded) plus LICENSE.txt, README.md, README.txt
and this document. The .NET 10 runtime
is required.

Fixed: read-ahead disposal no longer blocks or leaks permits

ChdFile.Dispose() and ConfigureReadAhead(0) used to wait for every in-flight read-ahead read.
A stream that ignored cancellation could stall teardown indefinitely. The manager now cancels,
returns immediately, and lets the last background task dispose its semaphore and token source.
In-flight hunks are deduplicated, so two tasks can no longer race to cache the same hunk and leak a
permit. Shutdown cancellation is no longer logged as a decompression failure (important because
Warning+ events are forwarded to the CLI bug-report sink).

Fixed: truncated CD sources are diagnosable

A short read while encoding a CD now reports the track, frame within the track, logical frame,
source offset (hex and decimal), sector size, bytes needed/read and the file length. Split-pregap
reads name the next track's file only when that file was actually used.

Full CI and security (new in v1.6.0)

  • CI gate - three-OS build/test across .NET 8/9/10, InspectCode, NuGet packaging, merged
    coverage, a Jekyll docs build and a quick chdman parity battle.
  • CodeQL for C# and GitHub Actions, Dependency Review on pull requests, and
    OpenSSF Scorecard results published to code scanning.
  • Dependabot alerts, security updates and grouped version updates; NuGet audit of direct
    and transitive packages, with -warnaserror in CI.
  • Secret scanning with push protection, private vulnerability reporting, read-only default
    workflow permissions, mandatory full-SHA action pinning and artifact provenance attestations on
    releases.
  • SECURITY.md documents the reporting process and how to verify a release.

Verification

  • dotnet test across net8.0/net9.0/net10.0: 14,013/14,013 passed
    (4,216 library tests + 455 encoder tests per target framework).
  • Full battle harness: 3,174/3,174 checks, byte-identical chdman output.
  • jb inspectcode CSharp_CHDSharp.sln --severity=WARNING: 0 findings.
  • No public API changes - behavior fixes and repository infrastructure only.
