Alpaquita Linux 23: Release Notes

1. Introduction

The release notes give you late-breaking information about BellSoft Alpaquita Linux 23 release. Please read this document carefully, as it contains information that is not included in other BellSoft Alpaquita documents.

Kernel version

Alpaquita Linux ships 6.1 kernel version that is the LTS version with the longest period of support. This kernel version will continue to be updated to include all required security and major functional fixes. Note that our release supports smooth kernel updates when the previous kernel version is not deleted right away and can be used for boot or in the roll back.


This release supports x86_64-based processors for all deliverables - iso, minirootfs, package repositories, and docker images.

  • Intel (x86-64-v2)

  • AMD 64-bit (x86-64-v2)

Modern CPUs can provide optimal extensions for better performance in the core system libraries. x86-64-v2 provides proper support for new CPU features (CMPXCHG16B, LAHF-SAHF, POPCNT, SSE3, SSE4_1, SSE4_2, SSSE3), vector instructions up to Streaming SIMD Extensions 4.2 (SSE4.2), Supplemental Streaming SIMD Extensions 3 (SSSE3), the POPCNT instruction (useful for data analysis and bit-fiddling in some data structures), and CMPXCHG16B (a two-word compare-and-swap instruction useful for concurrent algorithms).

Aarh64 architecture is planned to be supported in later releases.
