v0.11.0

Features

• Checkpoint and rollback: Automatically create checkpoints before session execution, enabling rollback to restore files to their pre-execution state
  • Original file content stored as blob files in ~/.local/share/shannot/sessions/{id}/checkpoint/
  • Conflict detection via post-exec hash comparison (bypass with --force)
  • Support for both local and remote (SSH) rollback
  • Large directory handling with limits (100 files / 50MB) and partial checkpoint warnings
  • New session status: rolled_back

CLI

• Add shannot rollback <session_id> command with --force and --dry-run options
• Add shannot checkpoint list to list sessions with available checkpoints
• Add shannot checkpoint show <session_id> to display checkpoint details

v0.10.3

Bug Fixes

• Fix self-test creating pending session on macOS (avoid uname -p subprocess)
• Fix self-test output showing summary message instead of script output

v0.10.2

Bug Fixes

• Fix SSL certificate verification for Nuitka binaries on macOS
• Fix macOS stdlib download URL (use PyPy 3.8 v7.3.11)

v0.10.1

Enhancements

• Auto-download sandbox binary: shannot run now automatically downloads the PyPy sandbox binary on first run (with graceful failure for unsupported platforms)
• macOS runtime support: Platform-specific PyPy versions (Linux: PyPy 3.6, macOS: PyPy 3.8) with automatic detection and download

v0.10.0

Features

• Deletion tracking: shutil.rmtree() and file deletions are now queued for approval
  • Full support for fd-based directory operations (fdopendir, dirfd, unlinkat)
  • Deletions displayed in approve TUI with file/directory counts
  • Audit logging for deletion events
• Add PyPy sandbox support for macOS ARM64
• Mount home directory read-only in sandbox VFS

Enhancements

• Add SHANNOT_SANDBOX=1 environment variable for sandbox detection by scripts
• Add darwin/arm64 struct sizes to validation
• Add check_output to subprocess stub for platform.node() support
• Add pwd stub and populate environ with HOME/USER for expanduser() support
• Add _bootlocale stub for text I/O encoding support
• Add missing syscall signatures (W* macros, dirfd, sendfile, mach_absolute_time, ftime)

Bug Fixes

• Fix misleading sandbox binary path in status message
• Fix Unicode output handling - preserve UTF-8 characters in sandbox output

v0.9.4

Enhancements

• Improve startup speed with lazy version loading (~88ms savings per CLI invocation)

v0.9.3

Bug Fixes

• Fix self-test regression: use --code instead of removed -c flag

v0.9.2

Enhancements

• Improve CLI help with quick start guide and clearer description
• Remove -c alias for --code flag (avoids Nuitka conflict, more self-documenting)

v0.9.1

Bug Fixes

• Use absolute path for shannot-mcp in Claude Desktop config (fixes PATH resolution issues)

Enhancements

• Improve devcontainer post-create experience
  • Use explicit shannot setup runtime command
  • Add shannot status verification step
  • Auto-activate venv in shell rc files for direct shannot access
  • Replace generic welcome with step-by-step "Try it out" tutorial

v0.9.0

Features

• Overlay commit model for file writes: File writes are now captured during dry-run and committed to the filesystem after approval, rather than being blocked
• Execution tracking: Commands and file writes are tracked during execution with per-item success/failure status
• Colorized execution summary: After execution, shows what commands ran and what files were written with ✓/✗ indicators
• Conflict detection: SHA256 hash of original file content is stored; commits fail if file was modified between dry-run and execution
• Large file handling: 50MB hard limit blocks excessive writes at capture time; 5MB threshold shows ⚠ warning in approval TUI
• Remote SSH file writes: commit_writes_remote() writes approved files to remote filesystem via SSH with conflict detection
• Conflict warnings in TUI: Show write conflicts prominently on Results view after execution

Changed

• Consolidated CLI commands: Merged shannot execute into shannot run --session=ID
• shannot run script.py now always uses dry-run mode (removed explicit --dry-run flag)

Bug Fixes

• Fix session execution for Nuitka binary by calling directly instead of subprocess
• Fix sandbox exit code by waiting for natural process exit before terminating
• Fix bytes/str type mismatch in remote conflict detection
• Fix fstat64 handling for write-mode files in VFS
• Fix basedpyright type errors in cli.py and mix_subprocess.py
