+###  0.0.21200 [Jan 17 2025]
+
+* Support for Microsoft Azure Blob Storage using [`azure_location`](./sql/external/location.md#microsoft-azure-blob-storage) was added.
+* Documented [`starts_with`](./sql/scalar_func/string.md) and [`ends_with`](./sql/scalar_func/string.md), as well as negative field positions for [`split_part`](./sql/scalar_func/string.md).
+* Fixed double free bug in Java Hyper API (reported in GitHub Issue [#133](https://github.com/tableau/hyper-db/issues/133)).
+* Improved performance of distinct aggregates (e.g., `SELECT COUNT(DISTINCT a) from t`).

 ###  0.0.20746 [Nov 7 2024]
 
 * Support for `array_contains`, `array_position` and `array_positions` was added

+
+To access data stored on Microsoft Azure Blob Storage, you can use the
+`azure_location` syntax. Hyper supports the `DFS` and `BLOB` endpoints and
+recognizes all of the following Azure URL formats:
+* `abfss://[email protected]/...`
+* `https://account.dfs.core.windows.net/container/...`
+* `https://account.blob.core.windows.net/container/...`
+
+Hyper also allows you to enter the non-SSL version of the URLs (`http://` and `abfs://`),
+however it will always establish SSL encrypted connections.
+
+Hyper's Azure support is highly optimized by using techniques such as concurrent
+requests, request hedging and prefetching. For maximum performance, ensure that you
+have a high network bandwidth to Azure Blob Storage, e.g. by running HyperAPI directly
+on Microsoft Azure compute.
