• api/v1/lib/allocator/allocator.proto
• api/v1/lib/executor/executor.proto
• api/v1/lib/maintenance/maintenance.proto
• api/v1/lib/master/master.proto
• api/v1/lib/mesos.proto
• api/v1/lib/quota/quota.proto
• api/v1/lib/scheduler/scheduler.proto

non-proto changes:

• operations: new helpers for additional offer operations
• operations: need test cases for new offer operations
• scheduler/calls: new helpers for ack offer op update AND reconcile offer op
• extras/scheduler: rule that acks offer op updates
• master: helpers for teardown and mark-agent-gone
• [ ] master: check for needed changes related to subscription heartbeats
• double-check diskinfo related checks in resources.go
• double-check reservation related checks in resources.go
• additional test cases for new disk validation
• additional test cases for new reservation validation
• additional test cases for new shared resource validation
• operations: support reservation refinements
• example frameworks: use allocation-info, it seems no longer optional
  • this should be fixed in latest Mesos, check that it's working as expected
• review latest upstream conversion code: apache/mesos@e55309a

deferred:

• scheduler: ReconcileOfferOperations is a synchronous call but the Response scheduler protos haven't landed yet: https://docs.google.com/a/mesosphere.io/document/d/1GGh14SbPTItjiweSZfann4GZ6PCteNrn-1y4pxOjgcI/edit?disco=AAAABAZjNtg
