[snyk-io]

This upgrade of jackson-datatype-jsr310 from version 2.10.1 to 2.21.2 is a series of minor updates within the same major version. While it consists mostly of bug fixes and improvements, it introduces a behavioral change that requires verification.

Key Changes:

• Behavioral Change in Duration Serialization: Starting with version 2.10.0, the serialization of java.time.Duration objects now correctly respects the SerializationFeature.WRITE_DURATIONS_AS_TIMESTAMPS setting. Previously, this setting was ignored. If your application enables this feature, Duration objects will now be serialized as a numeric timestamp instead of the default ISO-8601 string format. [11]
• Stricter Compile-Time Type Checking: Version 2.10.0 introduced stricter generic type assignment checks for mapper.readValue() when used with a TypeReference. This improves type safety and may lead to compile-time errors in code that was previously accepted but incorrect, preventing potential runtime failures. [11]
• Long-Term Support (LTS): Version 2.21 is designated as an LTS release, which means it will receive security and bug fixes for an extended period. [10]

Recommendation:
Verify any logic that serializes java.time.Duration objects, especially if SerializationFeature.WRITE_DURATIONS_AS_TIMESTAMPS is enabled, to ensure the change in output format does not break downstream consumers. Review any new compile-time errors related to TypeReference usage.
