         <releaseNotes>
-            Version 4.4.9:
-              - Optimize parser property lookup with last property hinted linear scan
-              - Add hinted parse/try_parse/view_of overloads accepting a ULONG property index hint
+            Version 4.5.0:
+              - Add Provider.EnableTraceLoggingFullSchemaHashing() to distinguish TraceLogging events that reuse a name with different fields. Call it before enabling the provider; hashing is disabled by default.
+              - Bound underlying TraceLogging event-name reads and validate metadata lengths, including metadata within larger extended-data buffers.
+              - Fix underlying schema-key copy assignment recursion and preserve owned event names, including assignments from borrowed names.
