**Enhanced Compatibility & Migration Support**\
The minimum supported Android version has been upgraded from 5.0 (Lollipop) to 6.0 (Marshmallow), ensuring better security and performance optimization for modern Android devices while phasing out legacy OS support.

**Media3 Library Update**\
Updated the underlying media3 library to version 1.8.0, providing improved streaming stability, enhanced error handling, and better compatibility with the latest Android media framework specifications.

**Legacy SDK Migration Enhancement**\
Introduced the `localFileUrl` parameter in the ContentData class to enable seamless playback of content downloaded using the 2.x SDK version, facilitating smooth migration paths for customers upgrading from previous SDK versions.

**Modernized Authentication Architecture**\
Added the `authData` parameter to DrmConfiguration as a unified authentication mechanism, replacing the previous `token` and `customData` parameters for cleaner, more flexible DRM license authentication workflows.
