Replaced outdated ShortMessage functionalities with Symfony's Notifier component for handling SMS messages. Deprecated legacy `ShortMessage` components and introduced a transition layer for existing OVH configurations. Updated dependencies and environment setup to support the new implementation.
Introduced a new event subscriber to log SMS sent events with details such as recipient and message IDs. This enhances monitoring and debugging of SMS delivery.
Switched the entire short message notification system to leverage Symfony's Notifier component and its TexterInterface with SmsMessage. This update simplifies the implementation, removes custom short message handling, and aligns with Symfony's standardized approach.
Integrated Symfony Notifier into the project by adding it to `composer.json` and creating a configuration file `notifier.yaml`. Updated `symfony.lock` to include the recipe configuration for Notifier. Minor documentation formatting issues were also fixed in `index.rst`.
