De eerste stabiele uitgave van Rocky Linux is uitgekomen. De Linux distributie is ontstaan als afsplitsing van CentOS, de community edition van Red Hat Enterprise Linux, nadat Red Hat had aangegeven er niet meer verder mee te willen. Rocky Linux is nog steeds gebaseerd op RHEL en heeft ook een migratietool die overstappen makkelijk maakt. De release notes voor deze uitgave kunnen hieronder worden gevonden.
Rocky Linux 8.4We are pleased to announce the General Availability of Rocky Linux 8.4 (Green Obsidian).
Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux 8.4. Since this is the first Release of Rocky Linux, the release notes below reflect only changes in upstream functionality between point releases.
Supported UpgradesWarning: Migration to Rocky Linux 8.4 is not supported from Rocky Linux 8.3 RC1, Rocky Linux 8.4 RC1, or any other release candidates.
Conversion Tool AvailableThe community has created the migrate2rocky tool to aid in the conversion to Rocky Linux 8.4 from other Enterprise Linux systems. This tool has been tested and is generally known to work, however use of it is at your own risk. Community members have successfully migrated test systems to Rocky Linux from:
- Alma Linux (8.4)
- CentOS Linux (8.4)
- Red Hat Enterprise Linux (8.4)
- Oracle Linux (8.4)
While migrations may work from other point releases, only migrations from the current minor version release of Enterprise Linux are supported as candidates to upgrade from.
New ModulesBrand new in Rocky Linux 8.4 are the following new module streams:
Major Changes Security
- Python 3.9
- SWIG 4.0
- Subversion 1.14
- Redis 6
- PostgreSQL 13
- MariaDB 10.5
Networking
- IPsec VPN provided by Libreswan now supports TCP encapsulation and security labels for IKEv2.
- The scap-security-guide packages have been rebased to version 0.1.54, and OpenSCAP has been rebased to version 1.3.4. These updates provide substantial improvements, including: Improved memory management,
- The
fapolicyd
framework now provides integrity checking, and the RPM plugin now registers any system update that is handled by either the YUM package manager or the RPM Package Manager.Kernel
- Nmstate is a network API for hosts and fully supported in Rocky Linux 8.4. The
nmstate
packages provide a library and thenmstatectl
command-line utility to manage host network settings in a declarative manner.- The Multi-protocol Label Switching (MPLS) is an in-kernel data-forwarding mechanism to route traffic flow across enterprise networks. For example, you can add
tc filters
for managing packets received from specific ports or carrying specific types of traffic, in a consistent way.- The
iproute2
utility introduces three new traffic control (tc) actions;mac_push
,push_eth
, andpop_eth
to add MPLS labels, build an Ethernet header at the beginning of the packet, and drop the outer Ethernet header respectively.High Availability and Clusters
- Proactive compaction regularly initiates memory compaction work before a request for allocation is made. Therefore, latency for specific memory allocation requests is lowered.
- A new implementation of slab memory controller for the control groups technology is now available in Rocky Linux 8.4. The slab memory controller brings improvement in slab utilization, and enables to shift the memory accounting from the page level to the object level. As a result, you can observe a significant drop in the total kernel memory footprint and positive effects on memory fragmentation.
- The time namespace feature is available in Rocky Linux 8.4. This feature is suited for changing the date and time inside Linux containers. The in-container clock adjustments after restoration from a checkpoint are also now possible.
- Rocky Linux 8.4 supports the Error Detection and Correction (EDAC) kernel module set in 8th and 9th generation Intel Core Processors.
Compilers and Development Tools
- A persistent Pacemaker resource agent that maintains state data can detect failures asynchronously and inject a failure into Pacemaker immediately without waiting for the next monitor interval. A persistent resource agent can also speed up cluster response time for services with a high state overhead, since maintaining state data can reduce the state overhead for cluster actions such as start, stop, and monitor by not invoking the state separately for each action.
- The following compiler toolsets have been updated:
Identity Management
- GCC Toolset 10
- LLVM Toolset 11.0.0
- Rust Toolset 1.49.0
- Go Toolset 1.15.7
- Rocky Linux 8.4 provides Ansible modules for automated management of role-based access control (RBAC) in Identity Management (IdM), an Ansible role for backing up and restoring IdM servers, and an Ansible module for location management.
