# Release availability {#api-availability}

The `main` manual includes unreleased changes. Use the documentation for
your installed version and check the package constraint of your extension.
The first release containing a symbol establishes its availability; later
releases can refine permissions, privacy and failure behavior.

| Method | First release |
| --- | --- |
| `ConversationServiceInterface::startSession()` | 0.23.0 |
| `AbstractOptions::withCallerSource()` | 0.30.0 |
| `AgentRuntimeInterface::endProcess()` | 0.41.0 |
| `AgentRuntimeInterface::defer()` | 0.42.0 |
| `AbstractOptions::withSite()` | 0.43.4 |
| `ChatOptions::withoutAnswerCache()` | 0.43.11 |

The public stability contract is [API stability](https://docs.typo3.org/permalink/netresearch/nr-llm:api-stability@main). For complete changes,
consult [Changelog](https://docs.typo3.org/permalink/netresearch/nr-llm:changelog@main); a method's presence does not establish that an older
release implements every behavior described by this development manual.
