### Summary   
<!-- Insert your summary of changes below. Minimum 10 characters
required. -->
This pull request updates the package to version 0.13.1 and introduces
several reliability and stability improvements, particularly around
authentication, timezone handling, connection pooling, and type
processing. These changes are reflected in both the documentation and
the package configuration.

Release and documentation updates:

* Updated the package version to `0.13.1` in `setup.py` to reflect the
new release.
* Revised the "What's new" section in `PyPI_Description.md` to highlight
the main changes and improvements in v0.13.1.

Reliability and stability improvements:

* Fixed token handling for Microsoft Entra ID authentication to ensure
stable and reliable connections.
* Enhanced connection pool shutdown mechanism to prevent resource leaks
and ensure reliable cleanup.

Data handling improvements:

* Removed forced UTC conversion for `datetimeoffset` values, preserving
original timezone information in Python `datetime` objects.
* Refined UUID string parameter handling to prevent automatic type
coercion, ensuring predictable string processing.

-- **Enhanced Batch Operations:** Complete support for UNIQUEIDENTIFIER and DATETIMEOFFSET in `executemany()` operations with automatic type inference, enabling efficient bulk inserts of complex data types including UUIDs and timezone-aware datetimes.
-- **Streaming Large Values:** Robust handling of large objects (NVARCHAR/VARCHAR/VARBINARY(MAX)) in `executemany()` with automatic Data-At-Execution detection and fallback, supporting streaming inserts and fetches for massive datasets.
-- **Improved Cursor Reliability:** Enhanced `cursor.rowcount` accuracy across all fetch operations, including proper handling of empty result sets and consistent behavior for SELECT, INSERT, and UPDATE operations.
-- **Critical Stability Fixes:** Resolved memory leaks with secure token buffer handling, fixed resource cleanup to prevent segmentation faults during Python shutdown, and corrected type inference bugs in batch operations.
+- **Authentication Reliability:** Fixed token handling for Microsoft Entra ID authentication to ensure stable and reliable connections.
+- **Timezone Preservation:** Removed forced UTC conversion for `datetimeoffset` values, preserving original timezone information in Python `datetime` objects for accurate cross-timezone data handling.
+- **Connection Pooling Stability:** Enhanced pool shutdown mechanism with proper tracking to prevent resource leaks and ensure cleanup operations execute reliably.
+- **Predictable Type Handling:** Refined UUID string parameter handling to prevent automatic type coercion, ensuring strings are processed as intended.
