SparkClean v1.1.0

What's New in v1.1.0

Critical Memory Leak Fix

• Fixed 34GB RAM consumption crash caused by missing autoreleasepool in directory size calculations and full-resolution image loading in duplicate finder
• Added memory pressure monitoring that auto-cancels scans when system memory is critically low

Safety Hardening

• Protected path blocklist (30+ paths) prevents deletion of critical system and user directories
• Deletion audit log written to ~/Library/Logs/SparkClean/ on every cleanup
• Trash failure no longer silently falls back to permanent deletion
• isOwnedByUser check wired into deletion pipeline
• Path depth guard rejects shallow paths

Scan Accuracy Improvements

• Docker double-counting fixed — was showing ~64GB instead of actual ~29GB by counting VM disk + CLI-reported sizes
• Old Downloads now checks newest file date inside directories instead of directory modification date (prevents flagging active projects)
• Large Files scanner checks if parent directory already scanned by other phases
• Tightened orphaned app data matching to reduce false positives

New Cleanup Categories (10 added)

• HuggingFace Models, Ollama Model Cache, LM Studio Models
• Bazel Cache, Deno Cache, Poetry Cache
• Font Caches, Speech Data Cache
• Xcode Playground Cache, Provisioning Profiles

Performance

• Static ByteCountFormatter/DateFormatter (was allocating on every call)
• SHA256 buffer increased from 64KB to 256KB
• DuplicateGroup.wastedSize pre-computed at init
• autoreleasepool added to all tight enumeration loops
