Breaking Changes

• Breaking Changes without explicit PR/issue numbers

• All functional API classes are moved into the ai.backend.client.func sub-package.
  (#82)
  • Kernel is changed to Session.
  • The session ID field name in the response of Session objects is now session_id instead of kernel_id.
