We recently completed the first technical corrigendum to the 2008 standard and are working on maintenance towards the second technical corrigendum. To actively work on the Austin Group documents you need to join the austin-group mailing list. See the mailing list page for more information.
The specification is joint copyright IEEE and The Open Group. By submitting any information or material to the Austin Group (for example on the mailing list or the bug tracker), you grant each of the joint copyright holders an unrestricted, irrevocable license to use, reproduce, display, perform, modify, transmit and distribute those materials or information, and you also agree that copyright holders are free to use any ideas, concepts, know-how or techniques that you send us for any purpose.

Group materials are kept in the document register.The group also maintains a set of links to other related standards materials.
We're currently working on a major revision with expected output in 2023. We meet regularly at least bi-weekly by teleconference. There is a freephone number to join the teleconference. You need to join the mailing list to get a login id.
The Austin Common Standards Revision Group (CSRG) is a joint technical
working group established to develop and maintain the core
open systems interfaces that are the POSIX™ 1003.1 (and former 1003.2)
standards, ISO/IEC 9945, and the
core of the Single UNIX Specification.
The approach to specification development is "write once, adopt everywhere", with the deliverables being a set of specifications that carry the IEEE POSIX designation, The Open Group's Technical Standard designation, and the ISO/IEC designation. The current set of specifications is simultaneously ISO/IEC 9945, IEEE Std 1003.1 and forms the core of the Single UNIX Specification.
This unique development combines industry led efforts and the formal standardization activities into a single initiative, and includes a wide spectrum of participants. The group is free and open to participate in and features a balanced set of interest groups including commercial companies, influential figures from the open source community, liaisons from other standards groups, educational and government users, and user groups.
Working with the Open Source community
The group includes developers from the Open Source community. As part of acknowledging their valuable input the copyright holders have made several grants relating to use of the documentation in those projects. Some of these are listed: the Linux Man Pages project, the FreeBSD project, the NetBSD operating system, the Cygwin Project, Gunnar Ritter's Heirloom Toolkit and other tools, Joerg Schilling's pax and find, Jens Schweikardt book, and the ISPRAS Linux testing project.
