Job #982 is now in scope, role is REV

[0crat]

This pull request #982 is assigned to @Serranya/z, here is why; the budget is 15 minutes, see §4; please, read §27 and when you decide to accept the changes, inform @paulodamaso/z (the architect) right in this ticket; if you decide that this PR should not be accepted ever, also inform the architect; this blog post will help you understand what is expected from a code reviewer; there will be no monetary reward for this job

[Serranya]

@zCRUSADERz Why did you bump the version? This was not part of the task.

[zCRUSADERz]

@Serranya I needed a successful build in Travis CI. Probably I should wait until #981 PR is accepted?

[Serranya]

@zCRUSADERz exactly. Please remove this part of the commit and wait for #981

[zCRUSADERz]

@Serranya deleted.

[Serranya]

@zCRUSADERz There are test failures. Please take a look

[zCRUSADERz]

@Serranya on my machine, all tests passed, and AppVeyor build succeeded. Travis CI failed, because pdd gem requires ruby >= 2.3.0. See #980, #981

[zCRUSADERz]

@Serranya all checks have passed.

[Serranya]
