+## [2.0.9](https://github.com/pinecone-io/pinecone-python-client/compare/v2.0.8...v2.0.9)
+### Changed
+- Added [update](https://www.pinecone.io/docs/api/operation/update/) API. Allows updates to a vector and it's metadata.
+- Added ```state``` to index status. Allows the user to check what state the index is in with the ```describe_index``` call. An index can be in one of the following states:
+  - ```Initializing```: Index is getting ready
+  - ```Ready```: Index is ready to receive requests
+  - ```ScalingUp```: Index is adding replicas, it can still take requests.
+  - ```ScalingDown```: Index is scaling down replicas, it can still take requests.
+  - ```Terminating```: Index is in the stage of getting deleted.

 ### Changed
 - Changed the spec to add  ```pods``` and ```pod_type``` fields to ```create_index``` and ```describe_index```.
 - ```pod_type``` is used to select between ```'s1'``` and ```'p1'``` pod types during index creation.
 - The field ```pods``` means total number of pods the index will use, ```pods = shards*replicas```.
