💅 guestfs-tools-release-notes — the tea on guestfs tools 1.48

okay bestie, so this is guestfs-tools-release-notes(1), the guestfs tools release notes, and we're doing a full catch-up on everything that went down between 1.46 and 1.48. grab a snack 🍓

✨ RELEASE NOTES FOR GUESTFS TOOLS 1.48 ✨

These are the release notes for guestfs tools stable release 1.48, and they describe the major changes since 1.46. no cap, this is the whole glow-up list 💖

Guestfs tools 1.48.0 was released on 14 March 2022. mark your calendars, she's got a birthday 🎂

🛠️ virt-builder

New templates, and there are a lot of them: "alma-8.5", "centosstream-8", "debian-11", "fedora-34", "fedora-34" (armv7l), "fedora-35" "fedora-35" (aarch64) — shoutout to Lars Kaiser and Stef Walter for these 👑

Also, the new fedora-34 (armv7l) template is built to use UEFI. fancy ✨

🔐 virt-customize

The yescrypt password hashing method is now supported — ty Björn Esser, we love a secure queen 🫶

🕵️ virt-inspector

She now recognises "kalilinux", "kylin" and "msdos" operating systems / Linux distros (Laszlo Ersek). detection game: strong 💪

Inspection of LUKS encrypted filesystems placed directly on logical volumes is now supported, but heads up — you will need libguestfs ≥ 1.48 for that one (Laszlo Ersek). not negotiable, bestie 🙈

🧹 virt-sysprep

There's a brand new default operation called "net-nmconn" which removes NetworkManager connection profiles (Laszlo Ersek). out with the old profiles, periodt 💅

🪟 virt-win-reg

"virt-win-reg --version" now prints both the version of guestfs tools and the libguestfs library that it is linked with. two versions, one command, iconic 🌈

🌍 Common changes

All OCaml tools now suppress line wrapping when output is redirected to a file — and honestly? it's giving "make it easier to parse logs with external programs" 😌 (Laszlo Ersek).

There's a new --wrap option which can be used to re-enable line wrapping to files if you actually need it. so the vibes are optional, but the flags are real 💫

🏗️ Build changes

Multiple fixes to make it easier to build against either the system installed libguestfs or a locally built libguestfs (Laszlo Ersek). flexible build energy, we stan 🧚

Fix multiple OCaml warnings. Remove some deprecated OCaml features. And we now require OCaml ≥ 4.04. yes, that's a hard requirement, no skipping 🚨

Multiple fixes to valgrind support for glibc 2.35, OCaml 4.13 and libvirt 7.7. "make check-valgrind" should now work — go off 🔥

🧬 Internals

New OCaml "On_exit" module (from libguestfs-common) is used instead of custom on-exit and signal handling. cleaner, tidier, main character energy ✨

🐛 Bugs fixed

slayed, all of them 💀✨
