우분투 19.10 릴리즈


오늘 우분투 19.10이 릴리즈되었다. 이전 버전인 우분투 19.04를 사용하고 있다면 자동으로 업데이트 알림이 뜨며 업그레이할 수 있다. 아래는 릴리즈 노트.





New features in 19.10





Updated Packages





Linux kernel 🐧





Ubuntu 19.10 is based on the Linux release series 5.3. It adds a variety of new hardware support since the 5.0 kernel from 19.04, including support for AMD Navi GPUs, new ARM SoCs,
ARM Komeda display, and Intel Speed Select on Xeon servers. Significant
developer-facing features include pidfd support for avoiding races
cause by pid reuse, a new mount api, and the io_uring interface for
asynchronous I/O. To help improve boot speed the default kernel
compression algorithm was changed to lz4 on most architectures, and the
default initramfs compression algorithm was changed to lz4 on all
architectures.





Toolchain Upgrades 🛠️





Ubuntu
19.10 comes with refreshed state-of-the-art toolchain including new
upstream releases of glibc 2.30, ☕ OpenJDK 11, rustc 1.37, GCC 9.2,
updated 🐍 Python 3.7.5, Python 3.8.0 (interpreter only), 💎 ruby 2.5.5,
php 7.3.8, 🐪 perl 5.28.1, golang 1.12.10. There are new improvements
on the cross-compilers front as well with POWER and AArch64 toolchain
enabled to cross-compile for ARM, PPC64 LE, S390X and RISCV64 targets.





Security Improvements 🔒





Ubuntu 19.10
comes with additional default hardening options enabled in GCC,
including support for both stack clash protection and control-flow
integrity protection. All packages in main have been rebuilt to take
advantage of this, with a few exceptions.
