 # Major Change Log: 
 
 
+
+# Sync Now Integrated & ApplicationVersion Model Transition  
+### August 4, 2026  
+Sync from the main app streamlines into the Connect module, to do async bulk sync.  Additionally ApplicationVersion was transitioned from manual SQL to the ORM, for easier compatibility with the newer sync system.  The side effect functions of this have been tested to be stable.  
+</br>
+
 # Connect Module & Async  
 ### August 3, 2026  
 Introduced Connect Module, which manages HTTPx Clients, solves network/DNS issues, and coordinates Tor Bootstraps.  Introduced async & single endpoint full workflows.  This version is stable and tested for DNS & Tor problems.  Also modified Configuration to be Pydantic, instead of @dataclass_json, and changed the connection type to enums.  Further, there's a new enum function to get the new enum types, but the legacy function exists for backwards compatability.
