## Nomad 0.11.2
### Scheduler Scoring Changes
Prior to Nomad 0.11.2 the scheduler algorithm used a [node's reserved
resources][reserved]
incorrectly during scoring. The result of this bug was that scoring biased in
favor of nodes with reserved resources vs nodes without reserved resources.
Placements will be more correct but slightly different in v0.11.2 vs earlier
versions of Nomad. Operators do *not* need to take any actions as the impact of
the bug and fix only minimally affect scoring.
Feasability (whether a node is capable of running a job at all) is *not*
affected.
