+## [1.3.3] - 2024-10-03
+
+### Fixed
+
+- Fixed an issue where `pendulum.DateTime` objects were not properly serialized by `JsonSerializationWriter`. Now, `pendulum.DateTime` objects are correctly recognized as subclasses of `datetime.datetime` and serialized accordingly.
+
+## [1.3.2] - 2024-09-10
+
+### Added
+
+- Fixed numeric strings from being parsed as Datetime objects to being parsed as strings.
+- Only parse to Datetime objects that conform to ISO 8601 format.

 # Microsoft Kiota Serialization library for JSON
-[![PyPI version](https://badge.fury.io/py/microsoft-kiota-serialization-json.svg)](https://badge.fury.io/py/microsoft-kiota-serialization-json)
-[![CI Actions Status](https://github.com/microsoft/kiota-serialization-json-python/actions/workflows/build_publish.yml/badge.svg?branch=main)](https://github.com/microsoft/kiota-serialization-json-python/actions)
-[![Downloads](https://pepy.tech/badge/microsoft-kiota-serialization-json)](https://pepy.tech/project/microsoft-kiota-serialization-json)
 
-The Microsoft Kiota Serialization Library for JSON is a python implementation to serialize/deserialize JSON.
-
-A [Kiota](https://github.com/microsoft/kiota) generated project will need a reference to a json serialization package to handle json payloads from an API endpoint.
-
-Read more about Kiota [here](https://github.com/microsoft/kiota/blob/main/README.md).
-
-## Using the Microsoft Kiota Serialization JSON library
-
-In order to use this library, install the package by running:
-
-```cmd
-pip install microsoft-kiota-serialization-json
-```
