v0.3.0

Highlights

API: HTB v4 → v5

• HTB removed several v4 endpoints; machine list --todo/--unreleased/--sp-tier now use the unified v5 /machines, and machine submit uses v5 /machine/own.
• The API client is version-aware (per-call version=); default stays v4.

TUI

• Semantic colors (difficulty/OS/status), framed section headers and panels, a branded --help banner, and a TTY progress spinner.

CLI ergonomics

• Global flags (--json, --color, --wide, --token-file, --base-url, --timeout) now work before or after the subcommand.

Seasonal spawn

• machine start --wait now paces both the spawn retry and the IP poll with --interval; calmer retry messaging.

Fixes & docs

• Report VIP+ correctly in user info.
• Refreshed all screenshots (now showing the command run) via a new headless generator.
