# Changelog

## Unreleased

## v0.1.0-beta.2 - 2026-06-14

- Added generic `instance` DSL for lifecycle-managed compute boundaries with backend selection, nested host endpoints, nested services/resources, and target-scoped content planning.
- Added Incus instance backend support for launch/start/delete, proxy port exposure, readiness checks, and demo SSH bootstrap.
- Added backend-neutral `mix host_kit.instance status|ensure|destroy INSTANCE [config.exs]` for declared instance lifecycle.
- Added declarative backend options on `backend`, including block form with `option`, without leaking backend-specific flags into generic `plan`/`apply`.
- Added instance lifecycle apply events for launch, port exposure, readiness, and SSH bootstrap progress.
- Reworked Livebook demo VM helper to use HostKit instance lifecycle and expose both Caddy and Phoenix demo ports.
- Polished Phoenix Livebook to match the explicit Target / Declare / Plan / Deploy / Verify flow with Kino summaries and no hidden apply/verify checkboxes.
- Added SSH connection retry policy via `ssh retry: ...` with apply progress events for retry start/success/exhaustion.
- Added negative-path coverage for failed initial SSH connection and mid-apply transport failure handling.
- Improved plan/read-error formatting and compact Inspect output for plans, changes, and common resources.

## v0.1.0-beta.1

- Included Livebook demos and internal architecture guide in Hex package docs.
