----------------------------------------
### **Summary**
The main changes include switching the default configurations to use zstd (ZStandard) compression, updating the J2735 specification to the 2024 version, and updating GitHub Actions workflows with the latest versions of third-party actions from external repositories to remove Node.js and other deprecation warnings.
The main updates include:
- Changing the default configurations to use ZStandard (zstd) compression.
- Updating GitHub Actions workflows with the latest versions of third-party actions from external repositories to eliminate Node.js deprecation warnings.
- Introducing partial compatibility with J2735 2024.

However, there is a limitation. Due to a bug in the ASN.1 Compiler, the VehicleEventFlags bitstring has been reverted to its 2020 version, omitting the
eventJackKnife bit introduced in the 2024 revision. As a result, the eventJackKnife bit will not appear in output BSMs until the issue is resolved.

### Breaking Changes
In the 2024 TIM message specification, the following fields in the `TravelerDataFrame` sequence have been renamed. This is a breaking change to the XML encoding, requiring an update to the ODE POJOs. However, the UPER encoding remains independent of these names and remains backward compatible.
