Amazon Linux 2022 release notes update 2022-07-28
Amazon Linux 2022 was updated in preview July 28, 2022.
Major updates
This release represents the initial Release Candidate (RC0) for Amazon Linux 2022 (AL2022). A release candidate is a GA-like distribution (the feature set is frozen, and no major changes are expected between the Release Candidate and the Generally Available version) that will only receive patches and bug fixes leading to the AL2022 Generally Available release, with very few other changes. The Release Candidate is not recommended for production workloads and is intended only for testing purposes and to help you prepare for migration to Amazon Linux 2022.
Amazon Linux 2022 includes the following update.
-
This release represents the initial Release Candidate (RC0) for Amazon Linux 2022. You can use the Release Candidate to test compatibility with your applications or prepare for migration to Amazon Linux 2022.
-
There have been some changes to the build flags that will propagate throughout the packages over the next few months.
-
In this release, SELinux was switched from an enforcing to a permissive mode by default. You can change SELinux settings to enforced mode via command line by executing the
setenforce
command or by running this command on launch fromcloud-init
userdata.
Java Ecosystem
-
The
maven
,xmvn
, andjavapackages-tools
should function as expected, but the versions present in this release have not yet been rebuilt after a bootstrap phase. These packages will be re-built without the use ofjavapackages-bootstrap
before General Availability.
Known Issues
-
When launching the 2022.0.20220728 AMIs on certain instance types (using Xen hypervisors), the instance may see a delay during the instance launch and reboot before SSH is available. We are researching the cause of the issue, and it will be fixed in a future release.
Security Updates
-
For information on the CVEs addressed in this release, please refer to the Amazon Linux Security Center
.
Major changes from the first Tech Preview release to Release Candidate 0
-
Kernel updated from 5.10 to 5.15
-
OpenSSL updated from 1.1 to 3.0
-
AWS CLI updated to AWS CLI v2
-
AWS Tools found in AL2 have been added to the repositories like
ecs-agent
,aws-cfn-bootstrap
,aws-kinesis-agent
,ec2-instance-connect
, and other tools. -
Curation of packages - As part of the development cycle, we have curated the list of packages available in the repositories. This involved removing a number of packages that were no longer needed due to dependencies. Some package may be re-added to the repository as we work through customer requests.
-
Language run-times were updated and some runtimes like Ruby were name-spaced allowing newer versions to be added in the future without removing the current ones from the repositories.
