v0.2.3

TL;DR

• Press Enter to update - agentjail update no longer requires typing 'y', just hit Enter.
• Release highlights on install/update - see what changed right in the terminal after installing or updating.
• CHANGELOG.md backfill - v0.2.0–v0.2.2 entries added so every release has history.

Added

• Install-time changelog - the installer displays a compact "What's new" section with unicode bullet points extracted from the GitHub release notes; markdown artifacts are stripped for clean terminal output
• Update-time changelog - agentjail update shows the same "What's new" section after a successful self-update

Changed

• Update confirmation - agentjail update now accepts Enter to proceed (previously required typing 'y'); the stricter confirmation remains for policy disable and mcp allow/block
• Releases Worker changelog field - /v1/latest API response now includes a changelog field from release.body
• CHANGELOG.md backfill - added entries for v0.2.0, v0.2.1, and v0.2.2 that were previously missing
