  • December 2019: SysML v1. 6 release. The OMG Systems Modeling Language™ Version 1.6 (formal specification formal/2019-11-01) was adopted in December 2019. The specification is available at https://www.omg.org/spec/SysML/1.6/.  The update includes some relatively minor notational changes from SysML v1.5. A significant change for SysML v1.6 is that the stereotype constraints now have a formal OCL specification in addition to their textual description, except a few stereotypes that cannot be expressed in OCL. A more detailed description of the changes can be found on one of the SysML v1.6 co-chairs blog page at https://mbse4u.com/2019/12/05/whats-new-in-sysml-1-6/.
  • June 2018: SysML v2 API and Services RFP issued. A Request for Proposal (RFP) for SysML® v2 API and Services was issued at the June, 2018 OMG meeting in Boston, and is complementary to the SysML v2 RFP, which was issued in December, 2017. This RFP is intended to enable interoperability between SysML modeling tools and other model-based engineering tools.
  • January 2018: SysML v2 RFP issued. A Request for Proposal (RFP) for SysML® v2 was issued at the December, 2017 OMG meeting in Burlingame culminating a 1.5 year effort to develop the requirements for the next generation of SysML. SysML v2 is intended to improve the precision, expressiveness, and usability relative to SysML v1. A complementary RFP entitled the “SysML v2 API and Services RFP” is also being developed to enable interoperability between SysML modeling tools and other model-based engineering tools. A more detailed announcement can be found at https://www.omg.org/news/releases/pr2018/01-24-18.htm, and the SysML v2 wiki can be found here.
  • May 2017: SysML v1. 5 release. The OMG Systems Modeling Language™ Version 1.5 (formal specification formal/2017-05-01) was released in May 2017.  The specification is available at https://www.omg.org/spec/SysML/1.5/. A primary change from SysML v1.4 is the introduction of an Abstract Requirement that can be extended to support other kinds of requirements such as property-based requirements (refer to Annex E.8).
  • May 2017: SysML published as an ISO Standard. SysML has been published by the International Organization for Standardization (ISO) as a full International Standard (IS). The short title is “ISO/IEC 19514:2017” and the full title is "ISO/IEC 19514:2017, Information technology -- Object management group systems modeling language (OMG SysML®)". The direct catalogue reference is https://www.iso.org/standard/65231.html, and a preview of the IS is available at https://www.iso.org/obp/ui/#iso:std:iso-iec:19514:ed-1:v1:en
