# Versions

> Every config key, command, keybinding action and protocol verb, listed by the tuios version that added it.

This page lists what each tuios version added. The docs mark the same things with a badge:

- (Unreleased) means the feature is on tuios main and in no release yet. Build tuios from main to use it.
- (Added in v0.9.2) means the feature is in that release and every later one.

A badge for a version older than v0.8.0 is not shown, because most keys came before it. The list below has every version.

## How the list is made

A script reads the tuios repository. For each config key, command, keybinding action and protocol verb on main, it finds the first release tag whose source has it:

- **Config keys:** the paths of the config structs in `internal/config`.
- **Commands:** the `tuios` command tree, and the `Use:` lines in `cmd/tuios`.
- **Keybinding actions:** the action names in `internal/config`.
- **Protocol verbs:** the verb names in `internal/session`.

A few features have no key of their own, such as the seen state of mail. Each one has a probe string in `lib/since/features.json`. A version is the first tag that has the key, so a key that tuios renamed shows the version of the new name.
