abicheck v0.2.0

abicheck v0.2.0

This release delivers major improvements in cross-platform ABI analysis, report quality, and package-level workflows.

Highlights

• Cross-platform binary support: Windows (PE/COFF) and macOS (Mach-O) metadata analysis alongside Linux (ELF).
• PDB support for Windows debug/type analysis.
• Package extraction layer for ABI checks directly from RPM, DEB, tar, conda, and wheel packages.
• DWARF-only snapshot mode (headerless ELF analysis).
• Report filtering and deduplication:
  • --show-only
  • --stat
  • --report-mode leaf
  • --show-impact
• Suppression model enhancements:
  • label
  • source_location
  • expires
• MCP server support for agent/tool integration.
• GitHub Action integration (napetrov/abicheck@v1).

Notable fixes in release window

• compare-release: ignore non-ABI files during directory scans (e.g. .cdx.json, .tpl, .parquet) to prevent false matches.
• Architecture refactor stabilization and diagnostics hardening (PR #192).

Compatibility / behavior notes

• Redundancy filtering is enabled by default for cleaner reports; use --show-redundant to include derived changes.
• --show-only affects displayed output, not verdict/exit behavior.
• ABICC XML output includes redundancy annotations, but does not support --show-only.

Deferred to next release

• PR #158 (claude/implement-btf-ctf-formats-1gWOC) is intentionally deferred.
