The unresolved release note still advertises MigrationReport, which is absent from the exported models.

This update adds migration APIs and models, project environment/session/policy operations, new runtime and billing fields, and Appwrite 2.6.2 request metadata. It also adds path-segment encoding and changes redirect handling, alongside updated examples and tests.

81 of 115 changed files were too large to include in full.
