# Changes and compatibility

> Follow MCP and platform changes, availability boundaries, and compatibility guidance.

v3 MCP changes ship through the same release process as the rest of Apostra.
Release notes identify feature-specific availability and limitations. A new
documentation page does not by itself enable a feature for an account.

The [v3 limitations](/v2/setup/v3/limitations) page is the current compatibility
reference. Check it and the live `tools/list` schema before adopting a newly
documented workflow.
