Aether v1.0.0-beta.8

Aether v1.0.0-beta.8

The security & stability release. This build ships major hardening across the extension sandbox, frontend rendering, and Linux packaging — plus the first AppImage built entirely by our CI pipeline.

🔒 Security

• Modrinth Browser XSS fixed — mod titles, authors, descriptions and icons from Modrinth are no longer rendered as raw HTML. All card content is now built with safe DOM APIs, icons are restricted to cdn.modrinth.com over HTTPS, and a strict Content-Security-Policy is enforced inside the extension UI.
• Extension IPC hardened — messages between extension UIs and the launcher are now validated (origin + marker check) instead of accepting wildcard postMessage('*').
• Sandbox network hardening — HTTP redirects to non-allowlisted hosts are now blocked; response size limits enforced on all sandbox downloads.
• Atomic config writes — settings and account files are written atomically (.tmp → rename), so a crash mid-save can no longer corrupt them.
• Safer auth storage — accounts.json is mutex-protected against concurrent writes and auto-recovers (with backup) if found corrupted.
• Removed {@html} usage from toast notifications as defense-in-depth.

🐧 Linux

• AppImage rebuilt properly — correct AppDir layout (.DirIcon, desktop entries, hicolor icon) packaged via appimagetool, produced automatically on every build. If you previously had "the AppImage doesn't start", this build should fix it — please report back!

✨ Improvements

• Report bugs from Settings — new Help & Support section with one-click "Report a Bug on Discord".
• Offline resilience — Mojang's version manifest is cached locally (with request timeouts), and mod loader metadata is cached for 24h. Once cached, creating instances and launching loaders keeps working through outages and flaky DNS.
• Smoother Microsoft sign-in — transient DNS failures during login are retried automatically, with a clear offline hint instead of a cryptic error.
• Discord Rich Presence 1.0.1 — grass-block & per-loader icons, correct display for vanilla instances, fixed presence for single-character instance names, and no more dropped presence ("context canceled").
• Modrinth Browser 1.2.2 — cleaner version labels (no more duplicated names), tooltips, and graceful truncation of long entries.
• Mod Manager 1.0.1 — proper puzzle-piece icons instead of the generic ZIP icon.
• Instance creation hardened — names and paths are validated up front.

🛠️ Frontend Stability

• Fixed event-listener leaks that accumulated every time you visited Home or Settings.
• Extension pages now cleanly mount/unmount when switching sidebar tabs — no more zombie webviews.
• Instance details reliably reload when jumping between instances.
• Numerous Svelte reactivity fixes across navigation and forms.

📚 Docs

• SECURITY.md, API.md, and ARCHITECTURE.md updated to match the new sandbox behavior, IPC validation, and async extension loading pipeline.

v1.0.0-beta.7

🛡️ Stability – Whole Launcher Survives One Bad Extension

• Async reload refactored: pkg/extensions/manager.go – LoadAll is now metadata-only (<50ms), reloadSandboxes runs in background go with reloadMu serialization, per-extension 10s vm.Interrupt timeout (no global hang where one while(true) blocked all loaders). Server is reused (idempotent Start() + Stop()), no port leak.

• Context poisoning fixed (65f2ba9): NewSandbox now uses m.ctx for Aether.http.get/fs.download at launch-time. Previously the 10s timeout ctx was cancelled at loop end → all future launches failed Get "https://meta.quiltmc.org/...": context canceled (your 26.2 logs). Now 26.2 correctly shows Quilt is not available for Minecraft 26.2 with retry, not context canceled. Stale Reloading:true leak on manifest re-read also cleared.

• Instances never corrupted: pkg/instance/launcher.go only mutates in-memory classpath; instance.json is never deleted on ModLoaderHook failure. UI now should show Error with Retry / Reinstall loader / Launch as Vanilla instead of requiring deletion.

🎨 README

• All repos (Aether, Aether-Extensions, Aether-Cli, Aether-SDK) now have a branded Join our Discord badge (https://img.shields.io/badge/discord-Join%20our%20Discord-5865F2 – static, avoids WIDGET DISABLED). Main README.md adds matching Latest Release + GPL-3.0 badges.

📦 Extensions Gallery

• Aether-Extensions/index.json bumps: modrinth 1.2.1 (timeout + bundled ui/ fix), quilt 1.0.2, forge 1.0.1, neoforge 1.0.1, aether.discord-presence 1.0.0 (official). If gallery shows Gallery Unavailable, hit Try Again – raw.githubusercontent.com CDN is eventually consistent.

What's New

Import instances from other launchers

You can now import Minecraft instances straight from Prism Launcher, MultiMC, or the CurseForge app — no need to rebuild them from scratch.

• Auto-detects the launcher when you pick the instance folder.
• Brings over your mods, configs, resource packs, and world saves.
• Prism/MultiMC minecraft/ layout and CurseForge overrides/ are mapped to Aether's structure automatically.
• Import runs with a live progress bar and skips launcher-managed files (binaries, libraries) so Aether re-downloads them cleanly on Install.
• Version and mod loader (Fabric, Forge, NeoForge, Quilt) are detected from each launcher's metadata.
• Naming collisions are resolved automatically, and the import no longer chokes on symlinks.

Reliable self-updates on Linux

• AppImage users now download the correct AppImage artifact (previously the updater swapped in the wrong archive and broke the app).
• Updates verify the payload before swapping and apply atomically on Unix — no more ".old" gap.

Clearer errors + retries for flaky networks

• Transient network failures during mod-loader installs (e.g. "Temporary failure in name resolution") now retry automatically.
• Error messages for mod-loader issues no longer show raw GoError noise and point you to checking your connection.

Minecraft service connectivity status

• The launcher now pings Mojang + registry services and shows a status indicator in the sidebar.
• Home and the Create Instance screen warn you when you're offline before you try to install, so you don't hit confusing install errors.
