 ## [4.0.7](https://github.com/Ichinga-Samuel/aiomql/releases/tag/v4.0.7) - 2025-01-16
 
 ### Changed
+- 
 - Candles underlying DataFrame is now indexed by datetime.
 - Executor runs a strategy via the `run_strategy` method directly with `asyncio.run` without creating as a task.
 - `Strategy` class now has a initialize method that is called before the strategy is run.
 
 ### Added
+- 
 - `__add__` and `__iadd__` dunder methods for addition and inplace addition of dataframes or series objects to the Candles object.
 - `add` method for adding dataframes or series objects to the Candles object.
 
 ### Fixed
+- 
 - Candles timeframe attribute returns the correct TimeFrame object.
