Download the package matching your system from Assets below. All package builds
and their automated checks passed before publication. Full live-provider,
hardware and cross-desktop testing is still incomplete; see docs/VERIFICATION.md.

Target	Download
Ubuntu 24.04 (amd64)	penguin-studio_0.6.4-1+ubuntu24.04_amd64.deb
Ubuntu 26.04 / 26.04.1 (amd64)	penguin-studio_0.6.4-1+ubuntu26.04_amd64.deb
Fedora 44 (x86_64)	penguin-studio-0.6.4-1.x86_64.rpm
AppImage (x86_64, glibc 2.39+)	penguin-studio-0.6.4-x86_64.AppImage
Arch Linux / AUR recipe (x86_64)	penguin-studio-0.6.4-aur.tar.gz
Flatpak (x86_64)	penguin-studio-0.6.4-x86_64.flatpak
Snap core24 (amd64)	penguin-studio_0.6.4_amd64.snap
Optional RX 9070 camera GPU runtime (Ubuntu 26.04)	penguin-studio-camera-amd-gfx1201_0.6.4-1+ubuntu26.04_amd64.deb

Ubuntu DEBs are release-specific; do not install the 24.04 package on 26.04.
The RPM targets Fedora 44. Flatpak requires the Freedesktop 25.08 runtime
from Flathub. Snap requires snapd and local installation with --dangerous;
it is a development build, not a Snap Store publication.
AppImage targets x86_64 hosts with glibc 2.39 or newer. Make it executable and
launch it; --appimage-extract-and-run avoids a FUSE dependency. The AUR archive
contains a checksum-pinned penguin-studio-bin recipe, not a claim of publication
on aur.archlinux.org. Extract it, review PKGBUILD, then run makepkg -si on Arch.
AppImage and Arch installations currently use manual/package-manager updates;
the in-app updater offers release links instead of replacing those installations.

Penguin Studio window title

The main window title and startup banner now show Penguin Studio and its own version, without the inherited OBS version suffix. Profile and scene-collection names remain visible. Author credits, license notices and the About dialog attribution are preserved.

Camera processing, saved streaming accounts, encoders and the updater are unchanged from 0.6.3. The known sporadic Qt Wayland focus warning when opening the updater remains documented; this title-only update does not claim to resolve it.

Linux downloads

Ubuntu 24.04/26.04 DEBs, Fedora RPM, Flatpak, Snap, AppImage, the downloadable Arch recipe and the optional Ubuntu 26.04 RX 9070 camera runtime are built together. Verify downloads with SHA256SUMS. Penguin Studio remains a development preview.

Validation

All eight candidate package builds passed in GitHub Actions. The Ubuntu 26.04 package was opened with isolated English profiles on native Wayland and XWayland. Both reported Penguin Studio 0.6.4 - Profile: Untitled - Scenes: Untitled, exited normally without warning/error log entries and reported zero memory leaks. GPU background processing was active in the final preview capture. All three current previews are verified captures of this package using synthetic media.

The broader recording, account-restoration and GPU validation remains documented against 0.6.3; this release changes the title and startup banner only. An initial preview fixture had a read-only relocated GPU cache and fell back to CPU. Making that test cache writable restored GPU operation without a product code change.

Current English interface

Penguin Studio 0.6.4, captured from the real application with local demo media.

Final release checks

All eight final Linux package jobs and publication passed in Actions run 40211359245. Published asset sizes and SHA-256 digests match the source manifest. Both Ubuntu 26.04 files were downloaded and independently hash-verified. The local package-manager simulation upgrades Penguin Studio and the existing AMD camera runtime only, with no added or removed packages.

Installed Ubuntu 26.04 validation

Penguin Studio and the optional AMD camera runtime are installed as 0.6.4-1+ubuntu26.04; package-file verification passed. An isolated English-profile test of the installed application on native Wayland reported Penguin Studio 0.6.4 - Profile: Untitled - Scenes: Untitled, activated GPU background processing and exited normally with no warning/error log entries and zero reported memory leaks. This was a synthetic-media startup/title/effects/shutdown check, not a new live-camera or streaming-account test. The previously documented sporadic updater-opening focus warning remains outside this test.
