**AL2027 Preview**
AL2027 is currently available for preview, for more information see the [ AL2027 User Guide](https://docs.aws.amazon.com/linux/al2027/ug/what-is.html). It is intended for evaluation and testing only and is not recommended for production workloads.
## Special Announcements
+ On-premises images are now available in the AL2027 public preview. You can download images in VMware OVA, KVM/QEMU qcow2, Hyper-V VHDx, and raw formats from [https://cdn-al2027.amazonlinux.com/os-images/latest/](https://cdn-al2027.amazonlinux.com/os-images/latest/) to run AL2027 on your own virtualization platforms.
As with all preview components, these images are pre-release, aren't covered by AWS Support, and should be used only for evaluation and validation, not production. For production workloads, continue to run AL2023 until AL2027 reaches general availability.
+ AL2027 now ships NVIDIA repositories, which include the NVIDIA Linux GPU driver and CUDA. AL2027 will add more NVIDIA packages to these repositories in future releases. For more information, see [NVIDIA drivers](https://docs.aws.amazon.com/linux/al2027/ug/nvidia-drivers.html).
## Release summary
This release is an update to the AL2027 preview.
**Notable updates**
+ By default, we reduce the scope of ptrace for processes to their own sub-processes only. `kernel.yama.ptrace_scope` now defaults to `1` by removing the hard requirement on `elfutils-default-yama-scope` in the `elfutils-libs` package. Developer and debugging tools that need unrestricted ptrace can install the opt-in enabler package `elfutils-yama-ptrace-enable`. This package also provides `default-yama-scope` for backward compatibility.
+ The `mariadb1011`, `mariadb114`, `mariadb118`, `mariadb123`, and `mariadb-connector-c` packages are now built against AWS-LC instead of OpenSSL.
+ Starting with kernel version `kernel7.2-7.2.4-4.107.amzn2027`, AL2027 ships kernel modules in zstd-compressed format with a `.ko.zst` file extension, instead of the previous uncompressed `.ko` format. The kernel decompresses modules at load time. We recommend that you test any workloads that use kernel modules on this kernel and switch to compression-agnostic tooling such as `modprobe`. This is included in the `kmod-34.2-2.amzn2027.0.1` release.
**Security updates**
+ For information on the CVEs addressed in this release, see the [Amazon Linux Security Center (ALAS)](https://alas.aws.amazon.com/alas2027.html).
+ For visibility into the status of CVEs that haven't been addressed yet, see the [Amazon Linux Security Center CVE Explorer](https://explore.alas.aws.amazon.com/).
**Known issues**
+ The NVIDIA repositories do not yet support repository metadata signing. Signing support will be added in an upcoming release. For more information, see [Repository metadata signing in AL2027](https://docs.aws.amazon.com/linux/al2027/ug/repo-metadata-signing.html).
+ The `systemtap` package does not function on kernel 7.2 because of a kernel function signature change. If you need to use `systemtap`, remain on kernel 7.1. This issue will be fixed in the next release, which updates `systemtap` to version 5.6.
