v2.0.1

[2.0.1] – 2026-05-08

🔧 Internal Architecture Changes

• Reworked partition restore handling architecture

• StringGrid no longer stores internal restore variables or partition state

• Introduced dedicated internal restore record structure for:

  • partition metadata
  • restore parameters

• StringGrid is now used strictly as:

  • display layer only
  • read-only visualization component
  • separation of UI and restore logic for improved reliability

• Reduced risk of:

  • UI-state desynchronization
  • accidental data corruption
  • invalid restore state caused by grid modifications

---

🛠 Restore & Boot Configuration Improvements

• Improved automatic adjustment of:

  • MBR
  • cmdline.txt
  • fstab

• More reliable handling of:

  • PARTUUID replacement
  • boot device migration
  • restored system consistency

• Improved detection and replacement logic during image restore process

---

⚠️ Safety Improvements

• Added confirmation dialog before writing images to target devices
• Prevents accidental overwrite of disks or partitions
• Additional safeguard before destructive write operations are executed

---

🔒 Stability Improvements

• Improved internal consistency between restore engine and UI
• Cleaner separation between runtime data and presentation layer
• Reduced hidden side effects caused by UI component state usage

---

v2.0.0

Changelog

All notable changes to this project are documented in this file.

[2.0.0] – 2026-05-02

🚀 Major Release – Unified Command System

• Introduced a unified delete command system with clear semantic commands:

  • file
  • fileintree
  • allintree
  • dir

• Clear separation between:

  • file operations
  • directory operations
  • recursive tree operations

• Improved readability and maintainability of exclude files

• Deterministic and simplified command behavior

• Strict command-based execution model without external dependencies

---

🔒 Security Critical Change

• ❗ Removed all shell command execution from exclude system

• The system no longer supports:

  • shell calls
  • external command execution
  • system() / exec() usage
  • shell expansion or chaining

• All operations are now:

  • internally parsed
  • executed via filesystem API only
  • strictly sandboxed within the MountPoint

• Eliminated attack vectors:

  • command injection
  • shell expansion exploits
  • environment variable injection
  • argument injection via exclude file

---

🔄 Syntax Changes

• Standardized exclude file format:

• No shell parsing

• No escaping or chaining

• Wildcards supported internally: *, ?

---

✨ Improvements

• Clear semantic behavior of commands:

• file → single file or wildcard match

• fileintree → recursive file pattern deletion

• allintree → deletes contents of a directory (keeps directory)

• dir → deletes directory including all contents

• Reduced ambiguity in destructive operations

• Consistent and predictable execution behavior

• Improved path handling relative to MountPoint

---

🛠 Engine Improvements

• Refactored delete engine into direct filesystem dispatcher
• Removed dependency on external tools and shell
• Optimized directory traversal logic
• Consolidated duplicate traversal implementations
• Improved recursive deletion reliability
• Simplified internal logic for maintainability

---

🧪 Editor Improvements

• ✅ Added syntax validation in Exclude Editor before saving
• Prevents invalid or unsafe entries at edit time
• Detects:
• invalid commands
• malformed syntax (COMMAND = PATH)
• illegal or ambiguous paths
• Improves user feedback and reduces runtime errors

---

🔒 Safety Enhancements

• Strong MountPoint boundary enforcement
• Guaranteed prevention of path escaping outside image root
• All exclude entries treated strictly as data (never executable)
• Improved validation of parsed entries

---

⚠️ Breaking Changes

• Removed all legacy and shell-based command support
• Old exclude files are no longer compatible
• Migration to new syntax required

---

🔒 Safety & Stability

• Improved handling of non-existent targets
• More predictable behavior during deletion operations
• Clear distinction between destructive and non-destructive actions

---

v1.8.0

[1.8.0] – 2026-04-29

🚀 Highlights

• Improved reliability and consistency of MBR and fstab handling
• Safer restore process with deterministic behavior
• New exclude file editor with built-in syntax validation

---

✨ Improvements

• Checkboxes deletepartition3 and deletepartition4 are now only displayed if the corresponding partitions exist
• The cancel function for Create Image and Write Image now prompts for confirmation
• Introduced an internal editor for exclude files

---

🛠 Validation & Processing

• Added syntax validation when processing exclude files

---

💽 Improved MBR and fstab handling

Reworked fstab generation logic:

• System partitions (p1/p2) are always taken from the image
• Additional partitions (p3+) are preserved from the target device when available
• Automatic fallback to image entries if device entries are missing, only if the fallback is mountable
• Introduced consistent PARTUUID handling
• Unified mapping between MBR, fstab, and cmdline

Improved MBR processing:

• Clear separation between image-defined structure and device-specific data
• Avoids unintended disk signature changes
• Ensures deterministic restore behavior

Increased robustness:

• Better handling of incomplete or broken existing fstab files
• More reliable restore process on systems with additional partitions
