## Roadmap

Tempel has a **fixed scope**, and is **fully complete**. I'm happy with its design and implementation, and believe it meets all its objectives in its current form. I'm not anticipating significant changes.

Still, given the sensitivity of the problem domain, I plan to approach Tempel's official stable release as a phased rollout to allow time for feedback before locking things down:

| Phase | Date | Release | Appropriate for
| :-: | :-- | :-- | :--
| ➤ | 2024-02 | `v1.0-RC1` | Staging, with ephemeral or low-value data
| | 2024-05 | `v1.0` final | Production, with real data
| Phase | Date | Release | Appropriate for |

| | 2024-02 | `v1.0-RC1` | Staging, with ephemeral or low-value data |
| | 2024-05 | `v1.0` final | Production, with real data |

`v1.0` final will be considered "**done**"- the library is expected to need+see only minimal maintance from that point.

- Deref a `KeyChain` to see its contents.
- The default `keychain` options will return a `KeyChain` that includes all the keys necessary to fully support Tempel's entire API.
