3.0.0

Features

• Added support for configuring the FCM service-account key path with FCM_SERVICE_ACCOUNT_KEY_PATH.
• Added JSON-formatted responses for 503 Service Unavailable errors.

Bug fixes and security

• Fixed Redis authentication handling, including URL-encoding credentials and supporting rediss:// TLS URIs.
• Improved Redis and FCM error handling so partial failures, missing tokens, and missing date fields are logged or surfaced correctly instead of being silently ignored.
• Prevented credential leaks by redacting Redis secrets from logs/debug output and removing hardcoded secrets from source configuration and Docker image layers.
• Improved runtime robustness by avoiding response-handler panics, overflow-prone timeout math, and unmanaged background notification tasks.

Code quality

• Cleaned up Rust code to use more idiomatic error handling, fallible constructors, stronger types, and fewer unnecessary clones or allocations.
• Removed dead code, unused configuration, unused variants, and redundant helpers.

Tests

• Improved testability by removing direct environment reads from Redis helpers.
• Write new unit and integration tests increasing a lot code coverage
• Cleaned up duplicate test attributes.
