Will there ever be a Solaris 12?
There is a Solaris roadmap in page 33 of this slideware from https://blogs.oracle.com/openomics/entry/solaris_day_27nov2013_slides
Have a look to page 2 disclaimer first.
Update: Solaris delivery model has changed and instead of the major disruptive versions that used to be the norm, is moving to a continuous delivery model where new features and changes are introduced by updates, not upgrades.
The "major" version will then indefinitely stay at 11 and there will be Oracle Solaris 11.next updates.
This is described in this blog page: https://blogs.oracle.com/solaris/entry/new_solaris_sparc_roadmap
Note also that along with that announcement, Solaris 11 long term premier support was extended by 10 years, moving from 2021 to 2031 (and even 2034 for extended support).
Update2: Oracle Solaris 11.4 Beta has just been released.
Update3: Oracle Solaris 11.4 was released yesterday (2018/08/28) and was certified as conforming to the Single UNIX Specification Version 7 Standard.
Yes. There will be a Solaris 12. It will be released in the timeframe shown on the public SPARC/Solaris roadmap here: http://www.oracle.com/us/products/servers-storage/servers/sparc/oracle-sparc/sparc-roadmap-slide-2076743.pdf.
Unfortunately, I can't say more about Solaris 12 at this time.
To answer about development of Solaris, we (Oracle) have expanded the number of engineers working on Solaris by more than 2x since the acquisition.
We are are actively working on improving Solaris every day, and each successive version of Solaris adds new, unique innovations building on the last version. We just launched Solaris 11.2 on July 31, which we almost called 12 because of the number of large features we included in it.
Solaris 11.2 includes over 500 new features including:
- A new type of Zone (container) called "Kernel Zones" that behaves like a Solaris optimized hypervisor; allowing independent patch levels and updates in each Zone separate from the global zone and the other zones, and yet has nearly 0 performance impact.
- Unified Archives allow quick, simple and flexible golden image creation and deployment.
- Simple PCI-DSS compliance reporting and remediation.
- Enhanced SDN capabilities
- A distribution of OpenStack
