+# NautilusTrader 1.109.0 Beta - Release Notes
+
+The main thrust of this release is to refine and further bed down the changes
+to the identifier model via `Security`, and fix some bugs.
+
+Errors in the CCXT clients caused by the last release have been addressed.
+
+## Breaking Changes
+- `Security` now takes first class value object `Symbol`.
+- `Security` `asset_class` and `asset_type` no longer optional.
+- `SimulatedExchange.venue` changed to `SimulatedExchange.id`.
+
+## Enhancements
+- Ensure `TestTimer` advances monotonically increase.
+- Add `AssetClass.BETTING`.
+
+## Fixes
+- CCXT data and execution clients regarding `security` vs `symbol` naming.
+- `Security` equality and hashing.
+- Various docstrings.
+
+---
+
 # NautilusTrader 1.108.0 Beta - Release Notes
