Java 17 has made it to general availability status today with a number of improvements.

Sent out last year was a "request for comments" on "Maple Tree" as a new data structure for the Linux kernel. The latest version of the Maple Tree patches were sent out today with mixed results but for where gains are being made they can be quite significant.

For more than one year now Oracle engineers have been working on Trenchboot support for securely booting the Linux kernel. Sent out today is the third revision of this work for establishing a dynamic root of trust for measurement.

Oracle has published a new version of GraalVM, its open-source Java JVM/JDK implemented in Java that also supports other programming languages and execution modes. GraalVM continues to be quite an interesting effort given its various languages supported and interesting technical experiments/features in the name of greater Java performance and other innovative features.

Trenchboot continues to be worked on for providing boot integrity technologies that allow for multiple roots of trust around boot security and integrity. Oracle engineers on Friday sent out their latest Linux kernel patches so it can enjoy a "Secure Launch" by the project's x86 dynamic launch measurements code.

Oracle on Tuesday released Solaris 11.4 SRU33 as the latest monthly stable release update for this largely idling operating system. With the thirty-third stable release update to Solaris 11.4 are delivering some arguably long overdue features.

Oracle engineers have continued working on the "Maple Tree" data structure for the Linux kernel as an RCU-safe, range-based B-tree designed to make efficient use of modern processor caches.

Succeeding January's release of GraalVM 21.0 is now GraalVM 21.1 with many performance improvements and other new features.

Oracle continues advancing their "Unbreakable Enterprise Kernel" as the company's modified Linux kernel build offered to Oracle Linux users as an alternative to its Red Hat Compatible Kernel for their RHEL-based OS. Unbreakable Enterprise Kernel 6 Update 2 is out to end Q1'2021 with various new features.

Patches back in 2013 were proposed for "PRAM" as persistent over-kexec memory storage to allow saving of memory pages across kernel reboots via kexec or when hitting a new kernel via kexec. Nearly one year ago Oracle retook up the effort and sent out PKRAM as their "preserved-over-Kexec" RAM and now finally a second iteration of PKRAM has been published.

Oracle continues maintaining Solaris 11.4 with monthly stable release updates but there still is no public sign of anything past 11.4 for this operating system that was once exciting during the Sun Microsystems days. But with this week's 11.4 SRU30 release, at least there are many package updates.

Oracle today released their Unbreakable Enterprise Kernel Release 5 Update 5 intended for use on their RHEL-based Oracle Linux. Oracle's "Unbreakable Enterprise Kernel" tends to be a newer Linux LTS kernel with extra features compared to what is found in the current RHEL / Red Hat Compatible Kernel builds.

Oracle on Tuesday released GraalVM 21.0 as the latest version of their Java VM/JDK that also supports other languages and modes of execution.

GraalVM continues its quest as the virtual machine not only supporting Java but also additional languages and execution modes with a focus on stellar performance and speedy startups. GraalVM CE 20.3 was released on Tuesday as the latest for this open-source package supporting Java, Node.js, an LLVM runtime, and more.

Oracle has released Oracle Linux 8 Update 3 as the newest version of their RHEL8-based operating system.

After announcing Unbreakable Enterprise Kernel 6 back in March as their modified kernel based currently on the Linux 5.4 source tree while adding and back-porting extra features, UEK R6U1 was released today as their first major update to this kernel that can be found on the likes of Oracle Linux and powering the Oracle Cloud.

More than a decade ago Linux users tended to be envious of Sun Microsystems' Solaris for ZFS and DTrace as the two most interesting technical selling points of the platform. In that time OpenZFS is now extremely vibrant for offering ZFS on BSD and Linux systems while DTrace is barely brought up these days. This tracing framework originally developed for Solaris was fantastic back in the day but over the years Linux has stepped up its game with various efforts. Now as we hit the end of 2020, Oracle engineers continue working on bringing better DTrace support to Linux.

With no new indications of Solaris 12 or Solaris 11.next and given the past layoffs and previous announcements from Oracle, today's statement that Solaris 11.4 will remain as their continuous delivery model with monthly SRU releases come as little surprise.

OpenJDK 15 is out today as the latest general availability release for this open-source Java implementation.

Oracle has put out another VirtualBox 6.1 point release though making it notable this time around is support for the upstream Linux 5.8 kernel.

While Unbreakable Enterprise Kernel 6 is the latest and greatest series for Oracle's kernel spin derived from upstream Linux 5.4 as an alternative on Oracle Linux to their "Red Hat Compatible Kernel", for those still making use of the Unbreakable Enterprise Kernel Release 5, a new update was issued today.

Along with Solaris 11.4 SRU24, another operating system update out this week from Oracle is the beta of their forthcoming RHEL7-based Oracle Linux 7 Update 9.

Solaris 11.4 continues chugging along per the Oracle/Solaris maintenance terms but still with no signs of life beyond the 11.4 series with any radical changes. The twenty-fourth stable release update was issued on Tuesday for Oracle Solaris 11.4.

While still on the Solaris 11.4 series and no signs of major advancements beyond it, SRU21 was released this week by Oracle with quite a number of package updates.

While Red Hat Enterprise Linux deprecated Btrfs and no longer supports it on RHEL8, Oracle does continue supporting this Linux file-system on their RHEL-based Oracle Linux when using the company's "Unbreakable Enterprise Kernel" alternative to their Red Hat Compatible Kernel. An Oracle engineer put out a lengthy post outlining the highlights of Btrfs in their new Unbreakable Enterprise Kernel 6.

Oracle today released GraalVM 20.1 as their latest big feature update to this virtual machine implemented in Java that also supports not only JIT compilation but ahead-of-time compilation for Java software as well as supporting an LLVM runtime and other languages.

Oracle's Anthony Yznaga has sent out a proposal for "PKRAM" as a new means of being able to preserve memory pages of the currently running kernel so that they can be restored after launching a new kernel via kexec.

Following the recent release of Red Hat Enterprise Linux 8.2, Oracle has now released Oracle Linux 8 Update 2 as their RHEL8-based distribution with various extra features on top and even an alternative kernel option.

It turns out our recent OpenJDK 8 through OpenJDK 14 benchmarks caught some on Oracle's Java team by surprise. But they were able to replicate the outcome and as a result OpenJDK 15 will be seeing better out-of-the-box performance.

With no sign of Solaris.Next either as Solaris 11.5 or Solaris 12, nor is it really expected to happen following Oracle's actions in recent years from layoffs to dismissing Solaris 12 when it was on their road-map at one point for 2017, Solaris 11.4 continues just being SRU'ed.
