Worked on the palantir/foundry-platform-typescript repository to implement versioning for function templates by introducing an optional funcVersion field to the FunctionTemplateStrings type. This addition enables safer and more auditable deployments by allowing templates to evolve in a controlled manner across different environments. The approach focused on enhancing traceability and compatibility, ensuring that template changes can be tracked and managed effectively. Utilized TypeScript for type definition updates and maintained clear documentation throughout the process. Leveraged version control best practices to deliver the feature, laying the foundation for future improvements in template management and deployment safety within the codebase.
