## 2026-11-01: API v1 and MCP 0.5.0

The documented code version connects REST and MCP through one operation registry. Public reading is separate from personal learning data. OAuth uses learn:read, learn:write and separately selected credits:spend; tokens are bound to the REST or MCP resource. This is an interface changelog, not evidence of a production deployment.

Purchases and spending remain disabled (unconfigured) without approved prices, credit amounts and legal configuration. No test payment creates real credit. An OAuth scope alone is never permission to spend credits.

The public approved installation-package catalog is currently empty. A private library is not a public package source. Never assume a license. Without an explicitly approved package there is nothing to install.

## Migrate older calls

Use learning paths instead of the legacy-level view and current tool names instead of registered aliases. Existing grants gain no new permissions. Current MCP uses protocol 2025-11-25. No sunset date has been set for compatibility names; do not invent a deadline.
