This is a minor version upgrade for @twilio/flex-ui from 1.19.0 to 1.26.3. After reviewing the release notes for the intermediate versions, no breaking changes have been identified. The updates primarily consist of new features, performance improvements, and bug fixes.

Key Changes:

• New Features: The new versions introduce several features, including browser notifications, markdown support, improved error reporting, and hidden filters for the agent transfer directory.
• Dependency Upgrade: Version 1.19.0 included an upgrade to Handlebars v4.7.3. This was noted as a potential breaking change only for users of undocumented Handlebars features. As the starting version is 1.19.0, this should not impact the upgrade.
• No Breaking API Changes: The releases between 1.19 and 1.26 are backward-compatible in accordance with Twilio's semantic versioning for minor releases.

No developer action is expected to be required for this upgrade.
