The `initial` and `next` subdirectories of this directory are for release notes.

## For developers

Release notes should be added to `next` by editing existing files or creating
new files. **Do not add RELNOTE=yes comments in CLs.** Instead, add a file to
the CL (or ask the author to do so).

At the end of the development cycle, the files will be merged by being
concatenated in sorted order by pathname. Files in the directory matching the

Do not translate the content of code snippets, keep the original in English. For example, `list`, `dict`, keep them as is.

### Content of code blocks

Do not translate the content of code blocks, except for comments in the language which the code block uses.

Examples:

Source (English) - The code block is a bash code example with one comment:

```bash
# Print greeting
echo "Hello, World!"
```

Result (German):

- Comprehensive Javadoc on public APIs

## Test Conventions

- Test class names end with `Test`
- Test methods start with `test_` prefix
- Tests use `## Arrange ##`, `## Act ##`, `## Assert ##` comments
- Some integration tests require network access

## Important Notes for AI Assistants

1. **Resource Management**: Always use try-with-resources with `CurlResponse`.
