Amazon Linux 2023 version 2022.0.20220831 release notes
Note
These release notes are for a version of the Tech Preview of Amazon Linux 2023. This is an old Tech Preview and should no longer be used.
The Generally Available Amazon Linux 2023 is the successor to the Amazon Linux 2022 Tech Preview releases. For information about AL2023 and keeping up to date with Amazon Linux releases, see the Amazon Linux 2023 User Guide.
Major updates
Amazon Linux 2022 includes the following major updates.
-
There have been some changes to the build flags that will propagate throughout the packages over the next few months.
-
Starting with AL2023 version 2022.0.20220728, SELinux was switched from an enforcing to a permissive mode by default. You can change SELinux settings to enforced mode via command line by running the
setenforce
command.
Upcoming Changes in future Release Candidate AMIs and repos.
-
The legacy
pcre
package is deprecated and will be removed in a future Amazon Linux release. Thepcre2
package is the successor, and the few remaining packages in Amazon Linux 2022 that depend on the deprecatedpcre
library will be migrated topcre2
in future updates. -
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
, 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
-
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.

-
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 thesystem-journald
is the waysyslog
works, withjournalctl
as the client that can look at logs. -
The default
curl

package, which supports the most popular protocols. You can switch to the full-featuredcurl

-
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 fullgnupg
functionality, you can get the fullgnupg
by runningdnf 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.
