+# Contributing
+
+Thanks for your interest in contributing to this SDK! This document provides guidelines for contributing to the project.
+
+## Getting Started
+
+### Prerequisites
+
+- Java 11+
+- Gradle
+
+### Installation
+
+Install the project dependencies:
+
+```bash
+./gradlew build
+```
+
+### Building
+
+Build the project:
+
+```bash
+./gradlew build
+```
+
+### Testing
+
+Run the test suite:
+
+```bash
+./gradlew test
+```
+
+### Formatting
+
+Check and fix code style:
+
+```bash
+./gradlew spotlessApply
+```
+
+## About Generated Code
+
+**Important**: Most files in this SDK are automatically generated by [Fern](https://buildwithfern.com) from the API definition. Direct modifications to generated files will be overwritten the next time the SDK is generated.
+
+### Generated Files
+
+The following directories contain generated code:
+- `src/` - API client classes and types
+- Most Java files in the project
+
+### How to Customize
+
+If you need to customize the SDK, you have two options:
+
+#### Option 1: Use `.fernignore`
+
+For custom code that should persist across SDK regenerations:
+
+1. Create a `.fernignore` file in the project root
+2. Add file patterns for files you want to preserve (similar to `.gitignore` syntax)
+3. Add your custom code to those files
+
+Files listed in `.fernignore` will not be overwritten when the SDK is regenerated.
+
+For more information, see the [Fern documentation on custom code](https://buildwithfern.com/learn/sdks/overview/custom-code).
+
+#### Option 2: Contribute to the Generator
+
+If you want to change how code is generated for all users of this SDK:
+
+1. The Java SDK generator lives in the [Fern repository](https://github.com/fern-api/fern)
+2. Generator code is located at `generators/java-v2/`
+3. Follow the [Fern contributing guidelines](https://github.com/fern-api/fern/blob/main/CONTRIBUTING.md)
+4. Submit a pull request with your changes to the generator
+
+This approach is best for:
+- Bug fixes in generated code
+- New features that would benefit all users
+- Improvements to code generation patterns
+
+## Making Changes
+
+### Workflow
+
+1. Create a new branch for your changes
+2. Make your modifications
+3. Run tests to ensure nothing breaks: `./gradlew test`
+4. Run formatting: `./gradlew spotlessApply`
+5. Build the project: `./gradlew build`
+6. Commit your changes with a clear commit message
+7. Push your branch and create a pull request
+
+### Commit Messages
+
+Write clear, descriptive commit messages that explain what changed and why.
+
+### Code Style
+
+This project uses automated code formatting. Run `./gradlew spotlessApply` before committing to ensure your code meets the project's style guidelines.
+
+## Questions or Issues?
+
+If you have questions or run into issues:
+
+1. Check the [Fern documentation](https://buildwithfern.com)
+2. Search existing [GitHub issues](https://github.com/fern-api/fern/issues)
+3. Open a new issue if your question hasn't been addressed
+
+## License
+
+By contributing to this project, you agree that your contributions will be licensed under the same license as the project.

+## 1.0.1 - 2026-05-07
+* fix: fix request field serialization across all request types
+* Previously, required fields like `start_date`, `zip_code`, `lab_id`,
+* `user_id`, `collection_date`, and `lab` were annotated with `@JsonIgnore`,
+* causing them to be omitted from serialized request bodies. Optional fields
+* (`end_date`, `provider`, `cursor`, `next_cursor`, etc.) also lacked proper
+* `@JsonProperty` bindings and `NullableNonemptyFilter` handling.
+* This fix ensures all request fields are correctly serialized when making
+* API calls, resolving silent data-loss bugs where required parameters were
+* never sent to the server.
+* Key changes:
+* Replace `@JsonIgnore` with `@JsonProperty` on required fields across all request classes (activity, body, sleep, vitals, lab tests, link, meal, menstrual cycle, etc.)
+* Add private `@JsonProperty`-annotated accessors with `NullableNonemptyFilter` for all optional (`Optional<T>`) fields to ensure correct conditional serialization
+* Import `NullableNonemptyFilter` and `JsonProperty` in all affected request classes
+* 🌿 Generated with Fern
+
 ## 1.0.0 - 2026-05-06
 * Initial SDK generation
 * 🌿 Generated with Fern
