# Changelog

## [2.1.1] - 2026-08-11
### Added
- Stable setup/uninstall phase codes, environment and file metadata, complete self-test output, exception chains with HRESULT/stacktrace, and per-step rollback diagnostics.
- Installer-log fallback from ProgramData to Temp plus a setup button for opening diagnostic logs.
- Post-write verification of shortcuts, uninstall executable and essential uninstall-registry values.
- Regression coverage for pre-mutation rollback wording, diagnostic context, log fallback and UI-report isolation.

### Changed
- Pre-mutation failures now explicitly report that no rollback was required; completed rollbacks are only reported as successful when every restoration step succeeded.
- Self-test timeout handling is bounded after termination is requested and records kill/capture status.
- Technical installer acceptance is explicitly separated from BizTalk WMI/environment validation.
- Setup and uninstall preserve undeletable backup/quarantine data and record a successful completion with a cleanup warning.

## [2.1.0] - 2026-08-11
### Added
- Transactional Windows setup/updater with SHA-256 payload manifest, isolated staging, pre/post activation self-tests, rollback, shortcuts and uninstall registration.
- Certutil-compatible installer ZIP as Base64 TXT plus separate ZIP SHA-256 file.
- WMI-free application self-test and regression test project covering persistence, diffs, restore safety, CSV hardening and installer rollback.
- UAC manifest and single-instance protection for the management application.

### Changed
- Snapshot and plan JSON writes now replace files atomically and keep BOM-tolerant reads.
- Snapshot diffs identify artifacts by application and name.
- Restore planning rejects snapshots from a different target server.
- Real shutdown/restore requires confirmation of the fully prepared and saved plan.
