CHDSharp v1.6.3

CHDSharp v1.6.3 - What's New

Released: 2026-11-03 - Full changelog - NuGet

CHDSharp v1.6.3 is a small diagnostics release. createcd now keeps expected malformed-input
failures out of the Bug Report API while preserving the exact chdman-compatible console text and
exit codes. The vendored codec libraries are explicitly documented as frozen, and no encoder output
changed.

Fixed: expected createcd input errors no longer become bug reports

A report showed --createcd failed: "Unrecognized ISO sector size (...)" being filed as an
application defect. That input is rejected by chdman too (cdrom.cpp:2078, parse_iso): a
raw ISO must be a multiple of 2048, 2336 or 2352 bytes.

• createcd now logs InvalidDataException (malformed ISO/CUE/GDI/TOC, truncated BIN/WAV,
  invalid source layout) and FileNotFoundException (missing referenced file) through
  logger.UserError(...). The event stays at warning level in the console and rolling file logs,
  and the console text and exit code are unchanged, but it is no longer POSTed to the Bug Report
  API.
• Other ArgumentException / IOException / UnauthorizedAccessException failures still use
  logger.Warning(...) and are still reported.
• Regression test Createcd_rejects_iso_size_that_is_not_sector_aligned covers the reported
  non-sector-aligned ISO path.

Documentation: vendored codecs are frozen

AGENTS.md now has a Vendored codecs (frozen) section: VendoredFlac, VendoredLZMA,
VendoredZLib and VendoredZSTD are kept byte-for-byte verbatim for chdman parity and may only
be edited when strictly necessary - never to satisfy an analyzer, formatter or InspectCode finding.
The existing InspectCode and .editorconfig exclusions remain in place.

Verification

• dotnet build -c Release: 0 warnings, 0 errors.
• jb inspectcode --severity=WARNING --exclude="Vendored*/**": 0 findings; no vendored sources
  were modified.
• Library tests: 4,220 passed and encoder tests: 455 passed on each of net8.0, net9.0
  and net10.0.
• Quick chdman parity battle: 905/905 checks passed, byte-identical output.
• No public API changes and no encoder output changes.
