## AI overview

AWS has released Amazon Linux 2027 in public preview with SELinux enforcing by default. The change may require application and migration work because policies that only logged violations on AL2023 can block applications on AL2027. The release has no announced AL2023 end-of-support date, general-availability date, or in-place migration path.

## Source excerpt

AWS has released Amazon Linux 2027 in public preview, built on the AL2023 baseline with kernel 7.1 and SELinux in enforcing mode by default. Applications that pass on AL2023's permissive mode may fail under enforcing. The announcement gives no AL2023 end-of-support date, no GA date, and no in-place migration path. By Steef-Jan Wiggers
