SysML FAQ: What is new in the OMG SysML v. 1.5 minor revision?

OMG SysML v. 1.5 Minor Revision Change Summary:
As should be expected in a long (10+ years) series of minor OMG SysML 1.x minor revisions, the OMG SysML v. 1.5 minor revision includes only trivial tweaks to the language.

• Allows Requirement properties and taxonomies to be defined by specializing the SysML Requirement stereotype. Also adds Requirement compartment notation to show Requirement relationships.
• Adds Block compartment notation to show Signal Receptions.

Unsubstantiated Claims:
N/A

Critical Commentary:
It's not clear why the OMG bothered with such trivial revisions to OMG SysML 1.4. The time and effort squandered would be better spent accelerating the long overdue OMG SysML 2.0 revision process.
