antigravity-booster follows semantic versioning from 1.0.0 on (C29).

What semver coversCopy Anchor Link

Breaking changes ship only in a new major version. Within a major (^1.0.0), these stay compatible:

• the agb CLI surface: commands, flags and exit behavior (CLI reference)
• the plan.json schema (Plan schema)
• the .booster/ artifact layout (File layout)

Each breaking change is listed in the changelog.

Supported versionsCopy Anchor Link

Only the latest published version gets fixes, security fixes included. There are no long-term support branches. To report a vulnerability, see SECURITY.md.

Deprecation and removalCopy Anchor Link

A retired feature goes through two steps:

1. Deprecated. The command still works, but its help text marks it deprecated and names the replacement. Example: agb import-brain (bin/agb.mjs), replaced by agb plan.
2. Removed. The command or flag stays recognized but only prints an error that names the replacement. Example: agb tui (bin/agb.mjs), replaced by agb sidecar. The old TUI flag on the status command was retired the same way (bin/agb.mjs).

Removed commands lists every current entry. No fixed support window is promised for a deprecated feature. Removing one from the public surface is a breaking change, so it waits for a major version.
