Jenkins informs me about security updates for workflow-{cps,job,multibranch,support} but I get a warning in the Update Center for each of them:

Warning: This plugin requires dependent plugins be upgraded and at least one of these dependent plugins claims to use a different settings format than the installed version. Jobs using that plugin may need to be reconfigured, and/or you may not be able to cleanly revert to the prior version without manually restoring old settings. Consult the plugin release notes for details.

I checked the dependencies and as it seems, those four plugins require workflow-step-api in version 2.13, but 2.14 was released 3 months ago, according to its plugin site.
