Barn 1.1.0

Released on 2026-11-09. Barn 1.1.0 adds image and guest-architecture overrides,
live progress tables, and more reliable CPU/memory resizing. It embeds signed
image catalog revision 2026110502, with 9 distribution releases and 17
architecture-specific artifacts. The default remains Ubuntu 24.04 on the
host's native architecture.

Image and architecture selection

Use --image/-I and --arch/-A with plan, up, reload, recreate, and
resize to override the inventory for one command. Image overrides apply to
selected nodes, and suggested follow-up commands retain the selections,
overrides, and repository. Existing VMs require recreate to change their
image or architecture.

barn plan -I u24 -A amd64
barn up -I u24 -A amd64

init and generated setup templates save the choices into the new inventory;
validate accepts the same overrides without changing the file. Image info,
pull, and named imports accept -A. Architecture names include amd64
(x86_64, x64), arm64 (aarch64, a64), and native; image info and
image pull retain the earlier -a spelling.

Matching guests use HVF or KVM. Foreign guests use QEMU TCG for compatibility
testing, with a stable ARM CPU model for UEFI boot. On Linux, install the
target QEMU system emulator and matching firmware separately; barn setup
prepares native host dependencies. All nodes in a deployment share one guest
architecture.

Progress and results

Linux and macOS lifecycle commands, setup, network operations, image
transfers, and repository maintenance now share live progress tables and
consistent completion summaries. Terminal redraws stop before a prompt or
error, and redirected output uses ordinary lines. Validation lists the checks
it performed. Status tables and labels use plain ASCII, including [DONE],
[FAILED], and [CANCELLED]. Use --json or --yaml for structured results.

Recovery fixes

• Offline resize holds the deployment lock across inspection, shutdown, and
  commit, preserving QEMU process identity when another command tries to start
  the same node.
• Interrupted online resize retains a recovery marker before hotplugging.
  status reports that live CPU or memory may differ from the applied
  configuration; retry resize or restart the node to recover.
• Plans for deployment-wide changes include new nodes in the recreation scope
  and avoid suggesting an up command before recreation is complete.
• Lifecycle retry commands preserve an explicit official --repo, even when
  BARN_REPO points elsewhere. Missing native QEMU programs trigger host
  preparation; missing foreign Linux emulators name the required dependencies.

YAML parsing uses go.yaml.in/yaml/v4 4.0.0, and flag parsing uses pflag
1.1.0. Existing YAML input/output settings are retained, and unfinished YAML
documents report the parser's EOF line. Packaged licenses and SPDX documents
cover the updated dependencies.

Upgrade and downloads

Stop running macOS guests before replacing Barn.app, then upgrade:

brew update
brew upgrade pgsty/infra/barn

Or download and run this release's installer:

curl -fLO https://github.com/pgsty/barn/releases/download/v1.1.0/install.sh
BARN_VERSION=1.1.0 bash install.sh
barn version

The installer verifies the selected archive against checksums.txt. The
Darwin arm64 archive includes the signed, notarized CLI, hosts helper, and
Barn.app; the other archives and Linux DEB/RPM packages provide the CLI and
matching helper. VM disks, keys, and state remain under BARN_HOME.
