Tag or label releases (e.g., “Blocks_v2.1_2026-04-09.dwg”).

Layer conflicts: Updated blocks may use different layers, causing unexpected visibility, color, or plotting changes in host drawings.
Attribute mismatches: Adding, removing, or renaming attributes can break data extraction, schedules, or scripts that expect specific attribute tags.
Scale/Insertion point shifts: Changes in insertion point or geometry alignment can displace blocks in existing drawings.
Block name collisions: Different block definitions with the same name can overwrite desirable local definitions when reloading.
Loss of local overrides: Users who edited block instances locally (exploded, modified entities) may lose those changes if they reload/redefine blocks.
Compatibility problems: Blocks created in newer AutoCAD versions or using advanced features may not function correctly in older installations.
