Release Date: January 15, 2026
Type: Patch Release

🐛 Critical Bug Fixes

Output Folder Validation

• Fixed: Users could accidentally set output folder inside data folder, risking data corruption
• Impact: Added comprehensive path validation with clear error messages
• Prevents circular dependencies and accidental data loss

Baseline Constraints Not Persisted

• Fixed: Changes to perpendicular/temporal baseline constraints weren't saved to configuration
• Impact: Constraint changes now properly trigger interferogram pair regeneration
• Configuration file properly tracks baseline threshold settings

Subswath-Specific Interferogram Generation

• Fixed: All subswaths (F1, F2, F3) generated identical F1 references instead of proper substitution
• Impact: Each subswath now correctly references its own files
• Targeted string replacement prevents unintended substring matches

Alignment Workflow Improvements

• Fixed: Simplified complex partial alignment logic
• Impact: More predictable behavior with clear user prompts and backup protection
• Enhanced method change detection and backup workflow
