Ygg v0.6.1

Released 2026-08-27.

Highlights

Added the zero-token Pi migration inventory and the trusted local Pi
compatibility bridge.
Removed dead API and TUI surfaces, flattened the internal tool trait stack,
and moved duplicated protocol helpers into ygg-ai.
Fixed persistence and delegation journal contention, improved streaming
failure diagnostics, and removed accumulated workspace junk.
Replaced the experimental native-scrollback commit ledger with Pi's complete
retained-frame rendering algorithm, including full replay on resize or
offscreen mutation and complete terminal-owned resume hydration.
The first-party executable-extension catalog now contains ygg-browse,
ygg-mcp, ygg-subagents, and ygg-web-search.

Core crates and first-party packages target Ygg 0.6.1.
Executable extension bundles require API 0.2 and an exact Ygg version.
The first v0.6.1 startup automatically migrates managed v0.6.0 first-party
bundles and Ygg Serve; the retired ygg-hermes-memory bundle is removed while
its external data is preserved. Failed downloads remain retryable with
ygg extension update <name> and do not block core startup.
Prompt templates remain Pi-compatible; skills follow the Agent Skills spec.
