Release v8.48.1 - Critical Hotfix

🚨 Critical Bug Fix

This release fixes a critical startup failure introduced in v8.48.0 that prevented the service from starting.

Bug Details

Root Cause:

• Line 84 in src/mcp_memory_service/models/memory.py had a redundant local import calendar statement inside the iso_to_float() function
• Python scoping rules: the local import declaration made calendar a local variable within that function
• Exception handler at line 168 referenced calendar before reaching the import statement
• This caused: UnboundLocalError: cannot access local variable 'calendar' where it is not associated with a value

Impact:

• v8.48.0 service completely fails to start (infinite loop during Cloudflare sync initialization)
• Error repeats every ~100ms with continuous Cloudflare API calls
• Health endpoint never responds, making dashboard inaccessible
• All MCP Memory Service functionality unavailable

Fix:

• Removed redundant local import at line 84 (src/mcp_memory_service/models/memory.py:84)
• Module was already imported globally at line 21, making local import unnecessary
• Service now starts successfully and passes all health checks

Changes

Modified Files:

• src/mcp_memory_service/models/memory.py - Removed redundant import statement (1 line deleted)

Testing

• ✅ Service starts without errors (tested locally)
• ✅ Health endpoint responds correctly
• ✅ No timestamp parsing errors in logs
• ✅ Cloudflare sync completes successfully
• ✅ Dashboard accessible at https://localhost:8000
