This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this:

* -- * -- B -- O -- O -- O (a110685b8357276cb4a63ebc6ff421f42f461d94) \ N -- N -- N (92c8ebd0b9ec85a71e3993c4864d48bcbb30a012)

When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B.

Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below.

validation: scheduler use schedule_config instead of capabilities

Since ODP test suite will use default configuration for scheduler, all comparisons should be done against it rather than maximum possible values returned by capabilities.
