 # Release History
 
-## 1.0.0 (Unreleased)
+## 1.0.0 (2025-07-28)
 
 ### Features Added
 
-- Initial release. This version includes the core functionality for querying metrics from Azure Monitor using the `MetricsClient`, which was originally introduced in the `azure-monitor-query` package.
+- **Initial release** of `azure-monitor-querymetrics` package with core Azure Monitor metrics querying functionality.
+- Includes the `MetricsClient` for querying metrics from Azure Monitor resources.
 
-### Breaking Changes
+**Migration from azure-monitor-query**
 
-### Bugs Fixed
+This package extracts the metrics functionality from the `azure-monitor-query` package to provide a focused solution for metrics querying.
 
-### Other Changes
+**For existing users of `MetricsClient`:**
+- Migration is straightforward - only import paths need to be updated.
+- The API surface remains unchanged.
+- **Before:** `from azure.monitor.query import MetricsClient`
+- **After:** `from azure.monitor.querymetrics import MetricsClient`
+
+**For users of `MetricsQueryClient`:**
+- This functionality is **not included** in this package.
+- **Recommended alternative:** Use `MonitorManagementClient` from the `azure-mgmt-monitor` package.
+- The management client provides comprehensive Azure Monitor resource management capabilities.
+
+For more details, see the [migration guide](https://aka.ms/azsdk/python/monitor/query/migration).

 # Azure Monitor Query Metrics client library for Python
 
-The Azure Monitor Query Metrics client library is used to execute read-only queries against [Azure Monitor][azure_monitor_overview]'s metrics data platform:
+The Azure Monitor Query Metrics client library enables you to perform read-only queries against [Azure Monitor][azure_monitor_overview]'s metrics data platform. It is designed for retrieving numerical metrics from Azure resources, supporting scenarios such as monitoring, alerting, and troubleshooting.
 
-- [Metrics](https://learn.microsoft.com/azure/azure-monitor/essentials/data-platform-metrics) - Collects numeric data from monitored resources into a time series database. Metrics are numerical values that are collected at regular intervals and describe some aspect of a system at a particular time. Metrics are lightweight and capable of supporting near real-time scenarios, making them useful for alerting and fast detection of issues.
+- [Metrics](https://learn.microsoft.com/azure/azure-monitor/essentials/data-platform-metrics): Numeric data collected from resources at regular intervals, stored as time series. Metrics provide insights into resource health and performance, and are optimized for near real-time analysis.
+
+This library interacts with the Azure Monitor Metrics Data Plane API, allowing you to query metrics for multiple resources in a single request. For details on batch querying, see [Batch API migration guide](https://learn.microsoft.com/azure/azure-monitor/metrics/migrate-to-batch-api?tabs=individual-response).

+# Azure Monitor Query Metrics client library Python samples
+
+## Samples
+
+The following code samples show common scenarios with the Azure Monitor Query Metrics client library.
+
+For examples on authenticating with the Azure Monitor service, see [sample_authentication.py](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/monitor/azure-monitor-querymetrics/samples/sample_authentication.py) and [sample_authentication_async.py](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/monitor/azure-monitor-querymetrics/samples/sample_authentication_async.py).
+
+### Metrics query samples
+
+- [Send a query to resources using MetricsClient](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/monitor/azure-monitor-querymetrics/samples/sample_metrics_query.py) ([async sample](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/monitor/azure-monitor-querymetrics/samples/sample_metrics_query_async.py))
+
+## Prerequisites
+
+- Python 3.9 or later
+- An [Azure subscription][azure_subscription]
+- Authorization to read metrics data at the Azure subscription level. For example, the [Monitoring Reader role](https://learn.microsoft.com/azure/role-based-access-control/built-in-roles/monitor#monitoring-reader) on the subscription containing the resources to be queried.
+- Azure resource of any kind (Storage Account, Key Vault, Cosmos DB, etc.).
+
+## Setup
+
+1. Install the latest version of the Azure Monitor Query Metrics library:
+
+  ```bash
+  pip install azure-monitor-querymetrics
+  ```
+
+2. Clone or download this sample repository.
+3. Open the *samples* folder in Visual Studio Code or your IDE of choice.
+4. To run the samples, you need `azure-identity`.
+
+  ```bash
+  pip install azure-identity
+  ```
+
+5. To run the async samples, you need an asynchronous HTTP framework like `aiohttp`:
+
+  ```bash
+  pip install aiohttp
+  ```
+
+## Run the samples
+
+1. Open a terminal window and `cd` to the directory that the samples are saved in.
+2. Set the environment variables specified in the sample file you wish to run.
+3. Follow the usage described in the file. For example, `python sample_metrics_query.py`.
+
+## Next steps
+
+To learn more about Azure Monitor, see the [Azure Monitor service documentation](https://learn.microsoft.com/azure/azure-monitor/).
