[v2.6.3] - 2026-04-22

Fixes

• CC3 / iClone import caches: Scene['CC3ImportProps'] (e.g. pbr_material_cache) no longer blocks unused detection—when material_all() is empty, cache-only refs (including Blender’s 2× users per cell) are ignored for clean and RNA material scans (stats/ghost_users.py).

[v2.6.2] - 2026-04-06

Fixes

• Clean / unused materials: if Material.users > 0 (and not only a fake user) but material_all() finds no references, the material is no longer treated as unused—avoids false positives when a local material shares a name with a linked one or Blender holds other unmodeled refs. The same rule applies to RNA / Smart Select scans (the unified scanner uses analyze_unused_from_graph, not only materials_deep).

[v2.6.1] - 2026-03-27

Fixes

• Stats → Storage: action byte estimates include layered/slotted actions (Blender 4.4+): keyframes in channel bags on strips are counted, so values are no longer stuck at the 256 B minimum when Action.fcurves is empty.

[v2.6.0] - 2026-03-27

Features

• Stats for Nerds — Storage: local blend storage estimates (bytes per datablock type, largest IDs with type + library-override icons and names), including collections; packed totals on Overview. Implementation lives in utils/compat for reliable bl_ext loading.
• Smart Select / Clean (issue #15): materials and images used in Geometry Nodes are detected on library override objects (not only pure locals); pure linked objects are still skipped via is_object_linked_without_override.
• Clean: before removing rig objects, unparent scene objects that would be orphaned (keep transform) and remove Armature modifiers targeting deleted objects, with info reports.

[v2.5.0] - 2026-01-28

Features

• Missing file tools:
  • Finalized Relinker and Linked Library Replacer features.
    • Add “Relink All” button to Relinker

Fixes

• Missing file UI: fix text field paste + layout/truncation issues; center the detect-missing popup; refine replacement path handling (better dir vs file behavior).
• RNA analysis: expand datablock coverage and refine dependency tracking to reduce false “unused” results.

Internal

• Maintenance: remove deprecated recovery option; improve ignore rules for hidden dot-directories.

[v2.4.1] - 2026-01-14

Fixes

• Fixed indentation errors that prevented RNA dump from processing most data-blocks
• Fixed compositing nodetree detection by adding scenes as root nodes in dependency graph
• RNA dump JSON file now always generated regardless of debug print settings
• Refactored repetitive snapshotting code into _safe_snapshot() helper function

[v2.4.0] - 2026-01-13

Features

  • Increased dialog width to 1000px for better visibility
  • Items now display in 4-column grid layout to reduce vertical scrolling

Fixes

• Fixed node groups used by objects via Geometry Nodes modifiers not being detected as used
• Fixed RigidBodyWorld and other scene-linked data-blocks incorrectly flagged as cleanable
• Fixed area lights and other object data-blocks in scene collections not being marked as used
• Added safety checks to prevent crashes during RNA extraction (recursion limits, data-block validation)
• Fixed RNA extraction handling for objects' modifier node groups

Performance

• Significantly faster scanning across all categories using RNA analysis
• Single-pass dependency graph building shared across all category scans

[v2.3.1] - 2026-01-13

Fixes

• Integrate proper UDIM detection

[v2.3.0] - 2026-01-06

Features

• Added "Enable Debug Prints" preference to control debug console output
  • Debug messages now only print when this preference is enabled (default: off)
  • All debug print statements use centralized config.debug_print() helper

Fixes

• Fixed preferences not displaying in Blender 5.0 extensions
  • Preferences now correctly match the full module path (bl_ext.vscode_development.atomic_data_manager)
  • Added safe property setter to handle read-only context errors during file loading
• Fixed node groups used only by unused materials/objects not being detected as unused (#5)
  • Node groups now recursively check if parent node groups are unused
  • Fixed compositor node tree detection to use reference comparison instead of name
  • Fixed missing import error in node_group_compositors()
• Made Clean execute deletion synchronous for faster performance
• Fixed callback-initiated scan state not being preserved, causing scans to fail
• Fixed instanced collection usage detection

[v2.2.0] - 2026-01-05

Features

• Add loading bars; non-blocking timer-based UI (#10)
  • Operations no longer freeze the UI during scanning
  • Real-time progress updates with cancel support at any time
  • Descriptive status messages showing current operation details
• Unified Smart Select and Clean scanning logic
  • Eliminated code duplication between operations
  • Clean now only scans selected categories (more efficient)
  • Both operations use consistent incremental scanning for images and worlds
• Added manual cache clear operator for testing and debugging

Performance

• Optimized deep scan functions with caching and fast-path checks
  • Image scanning now uses cached results to avoid redundant scene scans
  • Early exit for clearly unused images using Blender's built-in user count
• Incremental processing for large datasets
  • Images processed in batches (5 per callback) to maintain UI responsiveness
  • Worlds processed one at a time incrementally

Fixes

• Fixed images used only by unused objects being incorrectly flagged as unused (#5)
• Fixed material detection in brushes and node groups (#6, #7)
• Fixed Clean operator not showing dialog when invoked programmatically (#8)
• Improved material detection in inspection tools (brushes, node groups)

Internal

• Refactored scanning architecture for maintainability
• Added comprehensive debug output for troubleshooting

[v2.1.0] - 2025-12-18

Features

• Added support for detecting unused objects and armatures (#1)
  • Objects not present in any scene collections are now detected as unused
  • Armatures not used by any objects in scenes (including direct use, modifiers, and constraints like "Child Of") are detected as unused
  • Smart Select and Clean operations now support objects and armatures

Fixes

• Fixed material detection in Geometry Nodes Set Material nodes
  • Materials used in Geometry Nodes' "Set Material" nodes are now correctly detected as used
  • Fixed legacy issue where materials in node groups (e.g., "outline-highlight" in "box-highlight" node group) were incorrectly flagged as unused
  • This was a hangover from Atomic never being developed past Blender 2.93, where Geometry Nodes Set Material nodes use input sockets rather than direct material properties
• Performance optimizations for Smart Select and Clean operations (#3)
  • Removed inefficient threading implementation that was causing poor performance
  • Implemented short-circuiting logic in Smart Select to exit early when unused items are found
  • Fixed UI operators to use cached values instead of recalculating on every draw call
  • Note: Further performance improvements are limited by Blender's Python API being single-threaded and requiring sequential access to bpy.data collections, making true parallelization impossible without risking data corruption

Internal

• Removed incorrect "Remington Creative" copyright notices from newly created files
• Updated repository configuration in manifest

[v2.0.3] - 2025-12-17

Fixes

• Fixed missing import error in missing file detection
