Amazon Linux 2022 release notes update 2022-08-31

Major updates

This is an updated Release Candidate (RC) for Amazon Linux 2022 (AL2022), RC1.

An RC is a version that is nearly ready for release, but is still being tested. An RC receives only patches and bug fixes leading to the Amazon Linux 2022 Generally Available (GA) release. A GA distribution feature set is stable with no major changes expected between the final RC and the GA versions.

An RC version is not intended for production workloads. It's intended for testing purposes and to help you prepare for migration to Amazon Linux 2022.

Amazon Linux 2022 includes the following major updates.

  • This release represents the updated Release Candidate (RC1) 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.

  • Starting with Release Candidate 0 (RC0), 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.

Upcoming Changes in future Release Candidate AMIs and repos.

  • The legacy pcre package will be removed post RC1 and will be completely replaced by the more modern pcre2 package.

  • The kernel package will see changes to improve aspects of security and performance, and, while core functionality will be maintained, some unused or deprecated features may be removed in future Release Candidates.

Java Ecosystem
  • The maven, xmvn, and javapackages-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 of javapackages-bootstrap before General Availability.

Known Issues
  • There is a known issue by which enabling FIPS mode with update-crypto-policies --set FIPS will result in a non functional system. This will be addressed in a future release.

Major changes from the first Tech Preview release to RC0

  • Kernel updated from 5.10 to 5.15

  • OpenSSL updated from 1.1 to 3.0

  • Amazon CLI updated to Amazon CLI v2

  • Amazon 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.

  • rsyslog is no longer installed by default, and thus the system-journald is the way syslog works, with journalctl as the client that can look at logs.

  • The default curl is part of the curl-minimal package, which supports the most popular protocols. You can switch to the full-featured curl if needed by running dnf install --allowerasing curl-full libcurl-full

  • The default gnupg is a minimal one, which is limited in functionality, but has the minimal code needed to GPG verify RPMs, and brings a minimal number of packages into AMIs and container images. If you need full gnupg functionality, you can get the full gnupg by running dnf install --allowerasing gnupg2-full

  • 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.
