Alpine Linux 3.15 Release Highlights, Significant Changes, and Deprecation Notes

Alpine Linux is a security‑focused lightweight Linux distribution designed for x86 routers, firewalls, VPNs, IP‑phone boxes, and servers, using musl libc and busybox to reduce size and runtime resource consumption, and providing its own apk package manager.

Alpine Linux 3.15 update includes the following highlights:

HIGHLIGHTS

Support for disk encryption in the installer

Out‑of‑tree kernel module support via AKMS

Preliminary UEFI Secure Boot support on x86_64

Linux Kernel 5.15 (LTS)

LLVM 12

Node.js 16.13 (LTS) / nodejs‑current 17.0

PostgreSQL 14

OpenLDAP 2.6

Ruby 3.0

Rust 1.56

OpenJDK 17

Kea 2.0

Xorg‑server 21.1

GNOME 41

KDE Plasma 5.23 / KDE Applications 21.08 / Plasma Mobile Gear 21.10

SIGNIFICANT CHANGES

Kernel modules are now compressed with gzip

The framebuffer driver in the kernel has been disabled and replaced by simpledrm

qt5‑qtwebkit and related packages have been removed due to upstream support loss

MIPS64 port has been discontinued and will receive no further releases

DEPRECATION NOTES

sudo will be moved to the community repository in Alpine Linux 3.16; it is recommended to replace it with doas , which remains in main.

php7 is being phased out; version 7.4 will receive only one more year of security support.
