# Helix 0.107.0: KV store TTL option refined

> The `ttl` option on `ctx.kv().setItem` now supports three distinct states, giving you finer control over expiration behavior.

## Headline changes

### Changed: `ctx.kv().setItem`'s `ttl` option is now three-state

The `ttl` option on `ctx.kv().setItem` now accepts three states instead of two. You can set a positive duration to expire the key after that time, pass `null` to explicitly remove any previously set TTL (making the key persistent), or omit the option entirely to leave the existing TTL unchanged. This lets you update a value without accidentally clearing or overwriting its expiration.
