On top of that, I have not had internet access till just the other day. My sincerest apologies for the delay in response. The last couple of updates have been a mix of both a bug fix affecting a few users(v1.4.8), and (v1.4.9) was a few general bug fixes. This version (v1.5.0) is a huge codebase organization and backend improvement for me this shouldn't really affect any end-users. Huge thanks to the people and users that use this! I will continue to add updates and improvements when needed. - Added: Website News & Release Feed: Added an interactive Updates & News section to the project website with JSON/RSS feeds and automated release synchronization. - Fixed: Live Client Logger & Diagnostics: Fixed live log line rendering, replaced silent error catches with structured diagnostics, and removed startup timer workarounds across window initialization and deep-link handling. - Changed: Launcher Architecture & Modularity: Refactored UI controllers (Auto Updater, RS3/OSRS Doctor diagnostics, and Tools hub) into focused modules and consolidated Linux /proc process monitoring, icon deployment, and streaming downloads. - Changed: Community: Added Code of Conduct, refreshed issue/PR templates, and synced public community files. https://launchpad.net/~danielcook2016/+archive/ubuntu/linux-jagex-launcher announcement-2026-11-14-ubuntu-ppa-snap-live Sat, 14 Nov 2026 12:00:00 +0000 Announcement Linux Jagex Launcher v1.5.0 is live on ppa:danielcook2016/linux-jagex-launcher for Ubuntu 26.04, 24.04, and 22.04 alongside Canonical Snap Store latest/stable (Rev 10), keeping native installs updated automatically. - Highlights: Ubuntu PPA: Published cleanly for Ubuntu 26.04 Resolute, 24.04 Noble, and 22.04 Jammy on ppa:danielcook2016/linux-jagex-launcher. - Highlights: Snap Store: Canonical Snap latest/stable updated to v1.5.0 (Rev 10) with Wayland/X11 desktop integration. - Highlights: Community Standards: Repository ships issue forms, PR checklist, contributing guide, security policy, and Code of Conduct. https://github.com/cook0001/Linux-Jagex-Launcher/releases/latest announcement-2026-11-13-arch-fedora-github-packages Fri, 13 Nov 2026 12:00:00 +0000 Announcement Due to upstream AUR downtime, native Arch Linux (.x64.pacman) and Fedora/RHEL (.x86_64.rpm) packages alongside AppImage, .deb, and source tarballs are hosted directly on every GitHub Release. - Highlights: Arch Linux: Install the .x64.pacman package from GitHub Releases using sudo pacman -U or build from packaging/aur/PKGBUILD. - Highlights: Fedora & RHEL: Install the .x86_64.rpm package directly with dnf or use the cook0001/linux-jagex-launcher Copr repository. - Highlights: Verified Checksums: Every release publishes SHA256SUMS.txt verified automatically by the built-in launcher updater. https://github.com/cook0001/Linux-Jagex-Launcher/releases/tag/v1.4.9 release-v1.4.9 Fri, 13 Nov 2026 12:00:00 +0000 Release Resolve root-cause bugs across auth, launcher, updater, diagnostics, and renderer;

When running from inside an AppImage, RuneLite's launcher checked System.getenv("APPIMAGE"), mistakenly assumed the Jagex Launcher AppImage was RuneLite's own AppImage, and attempted to re-exec the Jagex Launcher binary in fork mode, causing RuneLite to immediately exit after hash verification. - Fixed: RuneLite & OSRS Process Lifecycle Tracking: Prioritized the actual game client (net.runelite.client.RuneLite) over the bootstrap jar (RuneLite.jar) in findOsrsPid(). Added successor process migration in startMonitoring() so when the bootstrap jar cleanly terminates after spawning the client, process monitoring smoothly shifts to the client PID instead of resetting game state. Extended JVM fork detection grace period to 15 seconds. - Fixed: OpenJDK 24+ ZGC Compatibility: Automatically detect and filter out -XX:+ZGenerational on OpenJDK 24+ where Generational ZGC is enabled by default and the JVM argument was removed. - Fixed: AppImage FUSE2-Free Static Runtime: Added AppImage toolset 1.0.3 static runtime configuration in electron-builder.json to run seamlessly on Ubuntu 24.04 and 26.04 without requiring legacy libfuse.so.2. - Fixed: Application Menu Launching & Stale Desktop Override Resolution: Fixed desktop integration in src/main/desktop.ts to properly resolve the application root directory rather than relying on current working directory. Cleaned up stale or broken user desktop overrides that previously shadowed system-installed launcher binaries. - Fixed: Single-Instance Lock & Window Focus: Enforced Chromium single-instance lock in src/main/index.ts with app.requestSingleInstanceLock(). Clicking the launcher from the application menu or dock now smoothly restores and focuses existing launcher windows instead of spawning duplicate competing processes. - Fixed: Wayland Window Presentation Fallbacks: Added secondary presentation fallbacks (did-finish-load and timeout) to ensure the main window displays reliably under Wayland and X11 compositors even if hardware acceleration frames are delayed. - Fixed: Linux Wayland / Vulkan Compatibility: Added --disable-features=Vulkan command line switch on Linux to prevent Chromium Ozone Wayland surface initialization conflicts. - Fixed: Application Menu Category Conformance: Corrected desktop entry categories in electron-builder.json to standard Game; ensuring consistent placement across GNOME, KDE Plasma, and XFCE application menus. - Added: Canonical Snap Release Pipeline: Added full Snap package build and distribution support (packaging/snap/snapcraft.yaml, snap/snapcraft.yaml, and npm run dist:snap) targeting core24 with strict confinement. Includes full interface plugs (removable-media, joystick, process-control, network-bind, opengl, audio-playback) and data persistence in SNAP_USER_COMMON across snap auto-refreshes. - Added: In-App Snap Format Detection: Added 'snap' package recognition to AutoUpdater and runtime paths in folders.ts, installer.ts, store.ts, osrs.ts, and desktop.ts. https://github.com/cook0001/Linux-Jagex-Launcher/releases/tag/v1.4.1 release-v1.4.1 Wed, 30 Sep 2026 12:00:00 +0000 Release Ubuntu 24.04 (noble) and 26.04 (resolute) t64 Dependency Resolution: Updated package dependencies in electron-builder.json and packaging/ppa/debian/control with transitional alternatives (libatspi2.0-0t64 |... - Fixed: Ubuntu 24.04 (noble) and 26.04 (resolute) t64 Dependency Resolution: Updated package dependencies in electron-builder.json and packaging/ppa/debian/control with transitional alternatives (libatspi2.0-0t64 | libatspi2.0-0 | libatspi-0, libgtk-3-0 | libgtk-3-0t64, libasound2 | libasound2t64, and added xz-utils, xdg-utils, libxtst6, libgbm1, libdrm2) ensuring seamless apt installation without broken package errors. - Fixed: Debian Rules Shared Library Scanning: Configured override_dh_shlibdeps in packaging/ppa/debian/rules to bypass scanning pre-compiled Electron binaries, resolving Launchpad builder failures. - Fixed: Asynchronous OSRS Network Diagnostics: Wrapped background socket and ping diagnostic probes in src/main/osrs-diagnostics.ts to prevent unhandled timeout rejections during network drops. - Changed: PPA Source Package Build Resiliency: Added automatic 4-attempt retry loop (RETRY_DELAY=30) and a 30-second cooldown (sleep 30) between series uploads in packaging/ppa/build-source-package.sh and .github/workflows/ppa.yml to prevent Launchpad rate-limiting. - Changed: Website Organization & Visual Polish: Re-architected docs/index.html and docs/style.css with centered block containers, comfortable side padding, left-aligned typography, official game crests, and anonymous screenshots. https://github.com/cook0001/Linux-Jagex-Launcher/releases/tag/v1.4.0 release-v1.4.0 Wed, 30 Sep 2026 12:00:00 +0000 Release Native Linux System Tray Support: Added system tray integration with right-click context menu, fast character launch shortcuts, background minimize toggle, and persistent tray status;
