Changelog

This file tracks the public Polaris release line.

Older historical tags remain in the repository for continuity, but the current public product line starts at v1.0.0.

v1.3.7 - 2026-08-07

A use-after-free in VAAPI DMA-BUF capture that AMD hosts on DRM/KMS have been running, and CI that finally builds the nix packaging it patches.

• Fixes a use-after-free at the VAAPI DMA-BUF import boundary: the VRAM converter destroyed its imported surface before importing the replacement, while an in-flight conversion could still be using it. Reachable on DRM/KMS capture and the non-cage wlroots VRAM path, which is what AMD hosts have been running
• Fails closed on an invalid surface or texture selection rather than converting it, and closes duplicated DMA-BUF descriptors once ownership transfers
• Keeps the gamescope-polaris patch stack and the packaged compositor in step, so the +polhdr2 stamp a session negotiates against is one a build proved
• Checks the vendored patch stacks on every push and builds the nix packages in CI, so a patch that cannot apply fails there rather than on a host
• Keeps npm audit --audit-level=high mandatory
• Retains exactly Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, Polaris-steamos3.8-x86_64.pkg.tar.zst, and Polaris-ubuntu24.04-x86_64.deb as the official release assets

v1.3.6 - 2026-08-07

Client-facing fixes for Nova, host setup advice that works on ostree systems, and gamescope session and HDR capture hardening.

• Prints the input-group command that works on ostree hosts, where the group lives in /usr/lib/group and usermod -aG input cannot find it; Bazzite gets ujust add-user-to-input-group
• Reports what the artwork resolve endpoint actually did, which Nova requires and no shipped build had ever sent, so library artwork update reported the host as unsupported
• Serves platform and runtime on library entries from the Lutris runner recorded at import, and only where the runner determines them
• Lets a manual artwork match decide which game a completion estimate is for, without falling back to the Steam app id that made the wrong estimate confident
• Records the fields Polaris serves to Nova in docs/nova-contract.json, derived from the source that serves them, and serves vaapi_vendor so a crash report names the driver generation
• Recovers gamescope session teardown from a dead nested marker, a non-leader attach, and an incomplete attach generation that refused later launches until restart
• Negotiates PipeWire capture formats against what the stream encodes, so 10-bit PQ cannot feed an SDR encode
• Claims the stream sink as the session default while streaming, and releases that claim only from the session that took it
• Keeps npm audit --audit-level=high mandatory
• Retains exactly Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, Polaris-steamos3.8-x86_64.pkg.tar.zst, and Polaris-ubuntu24.04-x86_64.deb as the official release assets

v1.3.5 - 2026-08-06

Package-update safety, Linux host integration owned by the package, and library playtime and completion estimates.

• Writes each mutable-distro download to the exact package filename with wget --output-document, preventing a pre-existing file from redirecting the new payload to .1 or .2 while a stale unsuffixed package is installed
• Makes Fedora, Arch, and Ubuntu update commands short-circuit after download, package-install, sudo -H polaris --setup-host, or restart failures
• Adds executable regression coverage for failed download, install, setup-host, and successful command paths across all three mutable package families
• Documents the v1.3.4 bootstrap caveat and provides exact-output commands for the first upgrade to v1.3.5
• Installs the udev rules and modules-load configuration as package files under /usr/lib, so the package manager owns them and removes them on uninstall
• Retires an unmodified /etc copy from an older install that would otherwise shadow the packaged rules, and keeps an edited copy with a warning naming the file in effect
• Lets --setup-host exit without root when the package already provides everything and the virtual input nodes are usable
• Adds a polaris-debug package to the Arch and SteamOS builds so coredumpctl info polaris yields a real backtrace
• Closes a systemd-inhibit process leaked on every session, and keeps a private session’s virtual keyboard and mouse out of the desktop session logged in at the machine
• Warns at startup when seat isolation is enabled and the account Polaris runs as is not in the input group, which otherwise leaves the isolated devices unopenable by Polaris and by the streamed game
• Warns when back_button_timeout is shorter than the 100ms Home press it emulates, since the setting is milliseconds and a value like 2 turns nearly every Back/Select press into Home
• Reports the playtime Steam and Lutris already record on disk, and serves completion estimates from a local dataset first, with beat_times_lookup controlling the How Long To Beat fallback; both are announced through /polaris/v1/capabilities so clients can adopt them explicitly
• Adds a transactional custom artwork workflow with an authenticated resolver, bounded downloads, and atomic caching
• Surfaces per-app environment variables in the web UI
• Releases the host loopback when a session turns host audio off, instead of leaving an earlier session’s loopback loaded for the life of the process
• Applies the session’s requested resolution and refresh when preparing the streaming display
• Keeps npm audit --audit-level=high mandatory and clears the advisories that were failing every web build
• Retains exactly Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, Polaris-steamos3.8-x86_64.pkg.tar.zst, and Polaris-ubuntu24.04-x86_64.deb as the official release assets

v1.3.4 - 2026-07-31

Patch release adding a dedicated SteamOS 3.8 package lane and tightening Linux package, path, setup, and import safety.

• Added fail-closed packaged binary path validation with explicit source-prefix remapping and retained validation receipts
• Added secure Bazzite support for the /home to var/home layout without broad canonicalization
• Dispatched setup-host early and standardized public host-integration commands on sudo -H polaris --setup-host
• Made ImageMagick discovery locale-safe during Steam cover import
• Added a dedicated SteamOS 3.8 x86_64 package built against Valve’s versioned repositories, with failure-safe installation and Desktop Mode package and startup validation only
• Kept physical Steam Deck gameplay, Game Mode, OLED 90 Hz, suspend and resume, and update persistence outside the certified support claim pending hardware evidence
• Kept npm audit --audit-level=high mandatory and the forbidden webtransport-go v0.10.0 dependency absent
• Standardized the official release on exactly Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, Polaris-steamos3.8-x86_64.pkg.tar.zst, and Polaris-ubuntu24.04-x86_64.deb

v1.3.3 - 2026-07-30

Patch release focused on configuration-save hygiene, controller boundaries, Linux recovery guidance, and Nix session reliability.

• Stripped response-only runtime, stream-path, credential-presence, and virtual-display metadata before configuration saves so valid v1.3.2 settings edits no longer fail backend validation
• Kept display-planner presets idempotent across repeated selection and stale dongle-discovery responses
• Made tray URL launching locale-safe on Linux desktops
• Rebound preallocated gamepad controller feedback after device reuse so rumble and related output follow the active client
• Added default-disabled client-gamepad seat isolation with distinct virtual-controller identities and explicit Linux seat-policy limits
• Documented how Bazzite users can restore Sunshine after testing or uninstalling Polaris
• Kept Nix-composed idle/session scripts ShellCheck-clean and removed temporary authority files after failed atomic runtime publication
• Retained the exact release assets Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, and Polaris-ubuntu24.04-x86_64.deb; Fedora 44 remains the sole Fedora package lane and npm audit --audit-level=high remains mandatory

v1.3.2 - 2026-07-30

Reliability patch focused on stream lifecycle, Linux private-session isolation, reconnect recovery, and truthful host diagnostics.

• Hardened RTSP follow-up control admission, live-session command ownership, session teardown, and serialized PulseAudio operations
• Prevented private-stream controller input from also navigating host Steam Big Picture while preserving normal game input
• Hardened private Steam teardown ownership and bounded interrupted process waits without broadly terminating desktop Steam
• Prevented private-session relaunch races by waiting for the prior Steam singleton to be fully released
• Preserved authenticated web sessions across host restarts and improved recovery from transient host outages
• Tolerated near-target stream FPS so healthy sessions are not mislabeled as degraded
• Exposed clearer Linux GPU probe topology diagnostics for capture-path troubleshooting
• Hardened Dashboard smoke navigation so release checks do not issue duplicate route requests

Security and release packaging

• Updated Browser Stream to webtransport-go v0.11.1 and quic-go v0.60.0, fixing remote memory exhaustion from unknown capsule buffering (CVE-2026-57497 / GHSA-g35j-m5xg-vh3q)
• Removed vulnerable, unnecessary web fixture-server dependencies and added npm audit --audit-level=high as a permanent CI gate
• Standardized the official release on exactly Polaris-arch-x86_64.pkg.tar.zst, Polaris-fedora44-x86_64.rpm, and Polaris-ubuntu24.04-x86_64.deb; Fedora 42/43 remain historical rather than current package lanes
• Added explicit Arch vulkan-headers / vulkan-icd-loader and Fedora vulkan-loader-devel package requirements
• Cleared GCC 15 warning-as-error blockers in Browser Stream setup, dormant preview diagnostics, and Linux display-topology helpers so exact-tag package validation builds cleanly

Linux stream modes / private runtime foundation

• Add first-class linux_stream_mode and linux_private_runtime config (Private Stream, Host Virtual Display, Mirror Desktop, GPU-native preference, Gamescope Stream, Headless Dongle).
• Keep legacy headless_mode / linux_use_cage_compositor / linux_prefer_gpu_native_capture as a compatibility mapping; UI and client-settings write both.
• Centralize mode resolve/apply/labels in stream_display_policy; path availability probes gamescope on PATH (and dongle outputs at apply).
• Introduce stream_runtime interface with labwc and gamescope adapters so process session start does not hard-code cage forever.
• Add stream_path registry (runtime × capture × topology) with reserved slots for community EVDI/Family Mode paths; honest runtime_backend for portal/host/gamescope/labwc.
• Document the path plugin contract in docs/stream-paths.md.
• Enable Headless Dongle path (headless_dongle): privacy/extended swap via kscreen-doctor (display_topology, headless_swap_mode); DRM sysfs connector discovery + /api/linux/display-outputs auto-suggest.
• Enable Gamescope Stream ownership: attach idle gamescope-0 (start polaris-gamescope-idle if needed) or spawn owned headless; wrap app launches into that runtime; never use gamescope-1 for portal.
• Harden portal/PipeWire capture: disconnect under loop lock; keep restore_token with invalidate+retry on SelectSources failure; wait for AvailableCursorModes ≠ 0; shared ownership so release cannot UAF negotiate/capture waiters.
• Solid-base stop path: Moonlight /cancel responds before nested teardown; owner cancel ignores stale sessiontoken (case-insensitive UUID); Browser Stream signals shutdown, releases portal/PipeWire, then joins capture (bounded) before pidfd-killing gamescope/labwc; terminate_impl and WebUI disconnect share the same prepare path.
• Harden Gamescope orphan recovery and nested teardown with generation-pinned socket reclamation, shared shell/C++ ownership locking, atomic session credentials, exact private-SID/pidfd cleanup, and fail-closed portal/idle rebinding.
• Dashboard preview tries labwc, gamescope-0/1, host Wayland (grim), then spectacle — works across stream paths.
• Web UI: selectable path cards write full config (including dongle outputs and gamescope/portal capture).
• SB-5 mode-neutral Steam apps (issue #5): migration v9 + load-time normalize unwrap polaris-gamescope-session hardwires to steam-appid + detached rungameid; gamescope path applies attach X11 env (no host Wayland) via stream_runtime::wrap_cmd / process. Optional Steam Big Picture may keep nested WSI shell.

v1.3.1 - 2026-07-12

Security and pairing-state patch focused on current cryptography dependencies, durable client authorization, and clearer paired-device history.

• Updated the Browser Stream helper’s Go cryptography and supporting modules, clearing the associated Dependabot alerts
• Added localized Added and Last seen values for paired clients while keeping unknown timestamps truthful for legacy records
• Hardened canonical X.509 client identity, revocation, duplicate-state validation, and authenticated request-time authorization snapshots
• Hardened paired-client persistence with private, cross-process atomic state replacement
• Improved paired-client controls so failed mutations remain visible instead of reporting false success in the web console

v1.3.0 - 2026-07-11

Feature release focused on self-service stream diagnostics, safer release visibility, display planning, and more resilient Linux capture startup.

• Added a manual Update Center with release metadata, package guidance, and a visible update call to action in the web console
• Added deterministic Polaris Doctor diagnostics and privacy-safe support reports for host readiness, active streams, and post-session troubleshooting
• Added optional AI Doctor explanations that translate deterministic findings without replacing the local-first diagnostic source of truth
• Added native network-path probes for route, latency, packet-loss, and reachability evidence in support workflows
• Added native controller, isolation, and haptics diagnostics so input-path failures can be separated from client or game behavior
• Added a display resolution planner that explains requested, host, capture, and output-mode compatibility before launch
• Expanded Mission Control and Troubleshooting self-tests, support bundles, and issue-draft generation with clearer remediation steps
• Improved Linux desktop capture startup by self-healing stale Wayland, display, and session-bus environment values
• Hardened headless DMA-BUF capture so conversion failures fall back cleanly instead of leaving private streams stranded
• Clarified NVIDIA, AMD/VAAPI, GPU-native, and fallback guidance across the public setup and troubleshooting docs

v1.2.1 - 2026-07-10

Patch release focused on CachyOS/Arch Settings reliability, Linux audio/capture diagnostics, and safer Moonlight-compatible host troubleshooting.

• Fixed Settings saves being blocked by an internal SteamGridDB clear-key flag, allowing unrelated Network and trusted-subnet changes to save normally
• Improved Settings pending-change handling so cancelled SteamGridDB key clears no longer reappear as phantom unsaved edits
• Added clearer backend error details for failed Settings saves so support can identify rejected config keys instead of treating every failure like a filesystem permission issue
• Improved PipeWire audio overrun diagnostics so stream support bundles and logs better explain audio-path failures during launch/connect attempts
• Clarified GPU-native Stream relaunch/fallback reporting for Linux hosts, including AMD/VAAPI SHM fallback messaging and vendor-neutral capture diagnostics
• Hardened Linux private/windowed compositor capture policy so cage/labwc runtime probes happen against the intended streaming runtime instead of a missing display context
• Refreshed public docs, screenshots, and install guidance for Moonlight-compatible users arriving through Fedora, Arch/CachyOS, Ubuntu, and Bazzite paths

v1.2.0 - 2026-07-03

Feature release focused on Nova-ready private/headless streaming, Portable Chrome cockpit polish, safer launch contracts, Linux input/capture hardening, and broader package coverage.

• Added the Portable Chrome web theme with a dimmer Moonlight-grey early-2000s retro-futurist skin, stronger chrome panel depth, restrained green status accents, and generic theme-toggle cycling across every registered skin
• Improved npm run smoke:web so release smoke gates can target live Polaris or built static web assets, check hashed JS/CSS assets plus the unauthenticated login page, and report a clear preflight when the live HTTPS server is not running
• Added a guided AI Auto Quality optimizer setup checklist with clearer provider/auth/runtime cards and actionable draft test feedback
• Polished release accessibility/mobile readiness with named icon controls, live status regions, trapped confirmation-dialog focus, and non-sticky handheld review bars
• Polished Mission Control live-session hierarchy with a stronger top summary for stream quality, latency, FPS, loss, bitrate, capture path, and runtime mode plus collapsible secondary live panels
• Added a sticky Library import staging summary and review drawer with source counts, per-game removal, clear-all staging, and already-imported confirmation
• Reduced idle web console polling pressure by deduplicating overlapping system/stream stats fetches and backing off transient fallback failures
• Added a Settings pending-changes review drawer with safe before/after values, save/apply impact labels, jump links, and per-setting reset controls
• Added confirmation dialogs and async toast feedback for host-affecting web actions such as disconnecting clients, recovery controls, stale display cleanup, and restart-sensitive quick toggles
• Hardened Linux lock-screen dismissal so a failed loginctl unlock-session attempt continues through other graphical user sessions before falling back to loginctl unlock-sessions
• Added Polaris v1 client/session surfaces for Nova: client settings advertisement, session status/stop integration, stream event queueing, and paired-client launch/input permission hardening
• Hardened private/headless launch policy around desktop Steam, mirror-desktop intent, strict gamepad isolation, host virtual-gamepad metadata, and headless bwrap setup
• Improved NVIDIA/Linux capture contracts with CUDA/GPU-native capability checks, DMA-BUF fallback diagnostics, virtual display output preservation, and headless VAAPI capture reinitialization
• Added openSUSE Tumbleweed build coverage and refreshed package/release workflows for the current Fedora, Ubuntu, and Arch asset line

v1.1.0

Feature release focused on the Polaris web console, Library workflows, safer pairing defaults, and NVENC split-frame hardening.

• Polished Mission Control degraded-state handling and Library management flows so active sessions, imports, and app editing are easier to scan and manage
• Renamed Auto Quality UI surfaces toward clearer stream-profile language
• Added a server-authoritative Game Control pairing access preset for QR/OTP and manual PIN pairing, granting list/view/launch plus input permissions without clipboard, file transfer, or server-command access
• Labeled paired clients with the exact Game Control permission mask as Game Control instead of Custom Access
• Hardened NVENC split-frame defaults by explicitly passing FFmpeg’s disabled split-frame value when split-frame encoding is disabled
• Improved Linux lock-screen dismissal so Polaris falls back from a systemd manager session to the graphical login session before running loginctl unlock-session
• Added web, pairing, and video regression coverage for the new access preset and split-frame default behavior

v1.0.18

Hotfix release focused on keeping cached AI launch profiles from forcing capable clients back to 720p.

• Bounded cached AI display-mode optimization by the explicit client request so Shield, Retroid, and Android TV launches that request 1080p keep a 1080p headless compositor
• Preserved history-safe recovery behavior so confirmed recovery profiles can still lower resolution or FPS when a recent session needs it
• Smoke-tested a Shield direct Steam launch with Nova v1.0.10, confirming the client request, Polaris-selected mode, labwc headless runtime, and Android decoder all used 1920x1080x60

v1.0.17

Hotfix release focused on session lifecycle cleanup after client End and terminate flows.

• Cleared stale paused/resumable session state when an app is explicitly terminated after the last stream client disconnects
• Emitted a terminal stream_ended lifecycle event from the terminate cleanup path so Nova can remove stale Active Session/Resume UI
• Made the session shutdown-request flag thread-safe between HTTPS controls and stream cleanup
• Added regression coverage for paused app termination, connected-client guards, duplicate idle suppression, and streaming cleanup handoff

v1.0.16

Stability hotfix release focused on client certificate verification during reconnect and disconnect flows.

• Fixed a crash in HTTPS client certificate verification by giving each verification request its own OpenSSL X509_STORE_CTX
• Protected paired-client certificate state while concurrent HTTPS threads verify Nova/Moonlight clients
• Added regression coverage for concurrent certificate verification against the pairing certificate chain
• Rebuilt local master with CUDA enabled and smoke-tested a Retroid Pocket 6 direct Steam launch through headless labwc, DMA-BUF GPU capture, CUDA conversion, and NVENC
• Confirmed the direct Retroid launch path stayed clear of inherited MangoHud and cleaned up the isolated session without a new coredump

v1.0.15

Hotfix release focused on keeping MangoHud out of Linux headless stream runtimes unless a game explicitly opts in.

• Suppressed inherited and session-pacing MangoHud injection for direct Steam game launches inside the headless cage compositor
• Kept explicit per-game MangoHud support available for direct game launches while continuing to block MangoHud for Steam Big Picture sessions
• Cleared MANGOHUD_CONFIG from the isolated labwc and XWayland runtime so compositor/helper processes do not inherit stale FPS-cap configuration
• Added policy coverage for direct headless cage launches and Steam Big Picture suppression
• Smoke-tested a direct Retroid Pocket 6 launch under a forced parent MANGOHUD=1 environment and verified stream child processes did not retain MANGOHUD*

v1.0.14

Patch release focused on Steam launch reliability, encoder/runtime polish, and safer Linux capture setup.

• Improved Steam library launch behavior, including direct Steam launch mode and non-default Steam library discovery
• Added NVIDIA NVENC split-frame encoding support, prepared FFmpeg wiring, configuration validation, and user-facing docs
• Improved Auto Quality and Adaptive Bitrate behavior so paired-client bitrate, recovery profiles, and clamp edge cases are handled more safely
• Added AMD GPU telemetry support and clearer dashboard handling for optional vendor-specific metrics
• Improved Linux unlock fallback, session cleanup, AMD headless DMA-BUF handling, and runtime diagnostics
• Added safe local development cleanup tooling with script coverage and building-guide documentation
• Hardened display selection so capture setup handles empty display lists without clamping against an invalid range

v1.0.13

Patch release focused on AI Auto Quality, Nova coordination, and Linux stream pacing diagnostics.

• Added richer Nova/Polaris settings sync so launch optimization, applied stream settings, presentation state, adaptive bitrate status, and optimizer health are visible across both sides
• Merged adaptive bitrate behavior into the AI Auto Quality path so recovery decisions can consider network pressure, host frame pacing, encode pressure, and session history together
• Improved AI optimizer feedback handling so short low-confidence sessions do not incorrectly relax safe FPS caps or poison game profiles
• Added safer history-based recovery profiles, including FPS fallback behavior and clearer host-render-limited session grading
• Improved Linux headless stream reporting for DMA-BUF capture, CUDA conversion, encoder target, frame residency, and SHM/CPU fallback reasons
• Added resumable disconnect handling and cleanup improvements for Steam and isolated cage sessions
• Expanded optimizer, adaptive bitrate, stream stats, process migration, and web UI coverage for the new Auto Quality flow

v1.0.12

Patch release focused on corrected Fedora/Bazzite NVIDIA release assets.

• Rebuilt Fedora 42, Fedora 43, and Fedora 44 release RPMs with CUDA enabled so NVIDIA/NVENC hosts can use the validated GPU-native upload path
• Added release validation that fails Fedora RPM packaging if a tagged release reports Build features: cuda=disabled
• Normalized the Fedora CUDA toolkit header patching flow for CUDA 13.2 headers and Fedora 42/43/44 release builds
• Fixed release dispatch packaging dependencies and Arch release validation so patch-release asset rebuilds are repeatable
• Kept the v1.0.11 Browser Stream and Linux runtime diagnostics behavior otherwise unchanged

v1.0.11

Patch release focused on Browser Stream validation and Linux stream-runtime polish.

• Added experimental Browser Stream using WebTransport and WebCodecs, with /browser-stream routing and /webrtc compatibility aliases
• Added the Polaris-launched WebTransport helper, browser session API, WebCodecs playback, and browser keyboard, pointer, wheel, and touch input routing
• Added Browser Stream UI modes for Game Mode, in-game expansion, pop-out streaming, stream profiles, latency statistics, and unsupported-browser messaging
• Improved Linux stream runtime diagnostics, stream display policy reporting, and GPU-native/headless capture path explanations
• Improved Linux launcher integration, labwc refresh-rate handling, headless preview diagnostics, and stream cleanup behavior
• Fixed Browser Stream close handling so the helper, transport, cage runtime, and launched Steam game are cleaned up together
• Fixed Steam handoff after Browser Stream cleanup so Nova/Moonlight launches are not blocked by stale Steam child processes
• Fixed isolated Linux audio routing so game audio streams that move back to the host sink are returned to the Polaris virtual stream sink
• Added isolated Linux process cleanup for Steam-launched children that escape the direct app process group
• Fixed SHM capture color handling for reported wlgrab pixel formats and expanded unit coverage for the copy path
• Tightened HDR metadata gating, web config save behavior, and Browser Stream route/config/status test coverage

v1.0.10

Patch release focused on Linux streaming diagnostics and host-session isolation.

• Gate true HDR streaming on display HDR metadata instead of client dynamic-range requests alone
• Add Linux true HDR diagnostics to logs, session status, and support data
• Document the KMS/DRM HDR validation path and current headless labwc SDR behavior
• Fixed Linux shader runtime path packaging so packaged builds can find shader assets correctly
• Isolated Linux headless audio routing so Polaris can capture its virtual stream sink without leaving the host desktop default sink redirected
• Added troubleshooting notes for Linux headless audio routing and HDR metadata validation

v1.0.9

Patch release focused on Linux headless color correctness and support clarity.

• Fixed AMD/Mesa true-headless SHM color channel handling for reported 3bpp and 4bpp formats
• Prevented the first-run welcome wizard from staying on Saving... when browser-side credential saving fails
• Clarified Headless Stream vs Desktop Display behavior on Linux
• Clarified current Linux HDR/Main10 limits and the recommended SDR VAAPI validation path
• Documented that Polaris can be installed alongside Sunshine, but both hosts should not run on the same default GameStream ports at the same time
• Clarified that Moonlight is not inherently capped to 60 FPS; Polaris respects the FPS explicitly requested by the client

v1.0.8

Patch release focused on Bazzite headless stream validation and host-session isolation.

• Fixed Linux EVDI virtual display output detection when Polaris opens a pre-created EVDI DRM card
• Documented the Bazzite EVDI initial_device_count=1 setup path for virtual display validation
• Replaced the Bazzite service override heredoc with a systemctl --user edit --stdin command and documented the validated headless labwc success markers
• Clarified the recommended Bazzite Headless Stream optimization, expected SHM/RAM capture warnings, and host-input isolation success markers
• Routed headless labwc virtual input through the labwc socket and blocked host uinput fallback when the headless runtime is active
• Cleared host DISPLAY from cage-launched app and Steam follow-up commands so launched processes stay inside the stream runtime

v1.0.7

Patch release focused on the first-run credential wizard.

• Documented the Bazzite composefs workaround for KMS capture: copy Polaris to /usr/local/bin/polaris-kms, apply setcap there, and run the user service from that writable copy
• Prevented the first-run credential wizard from staying on Saving... forever when the browser-side password request fails

v1.0.6

Patch release focused on first-run Bazzite setup clarity and web credential routing.

• Redirect first-run /login and /recover visits to the welcome wizard when no web credentials exist
• Clarified first-run setup URLs in the README and Bazzite guide
• Updated the Bazzite guide to run sudo polaris --setup-host --enable-kms for the DRM/KMS capture path

v1.0.5

Patch release focused on cleaner Bazzite/Fedora 44 packaging and headless runtime dependency coverage.

• Added the Linux headless runtime helpers to package dependencies: labwc, wlr-randr, Xwayland, and xdpyinfo/x11-utils
• Avoided GPU DMA-BUF capture when the build lacks a matching GPU upload path, preventing invalid CPU frame conversion in headless labwc sessions
• Added Fedora 44 RPM release assets for Bazzite 44 and Fedora 44 users
• Simplified the Bazzite install guide around one matching Fedora RPM layered through rpm-ostree

v1.0.4

Patch release focused on Bazzite tester feedback and credential recovery.

Highlights:

• Fixed BGR0 CPU-frame conversion fallback by inferring packed row stride when capture reports row_pitch = 0
• Prevented headless labwc fallback paths from failing encode conversion with src_stride=0
• Updated the Bazzite guide with labwc/wlr-randr layering, Desktop Mode-first validation, and known log-message guidance
• Marked Bazzite and Ubuntu package paths as extremely experimental tester paths until broader real-hardware validation is complete
• Clarified web credential recovery: run polaris --creds as the same user, restart Polaris afterwards, and avoid shell-confusing placeholder commands

v1.0.3

Highlights:

• Added an experimental Bazzite install path using the Fedora RPM through rpm-ostree
• Added a Bazzite validation checklist for desktop mode, gamemode, GPU, pairing, and headless behavior
• Added Ubuntu 24.04 DEB packaging: Polaris-ubuntu24.04-x86_64.deb
• Added an Ubuntu install guide with package, source-build fallback, and validation notes
• Polaris config saves now stay isolated from legacy Sunshine config paths

v1.0.2

Patch release focused on validated Linux release packages.

Highlights:

• Fedora 42 and Fedora 43 RPMs now build with package-style install paths under /usr
• Fedora RPM smoke tests install the generated RPM, verify the packaged binary, and check shared-library resolution
• Fedora 43 is now part of the official release asset validation matrix
• Arch package validation now checks the package against the current distro Boost runtime before release upload
• Public install docs were refreshed for Fedora 43 and current Arch package dependency behavior

v1.0.1

Patch release focused on dual-distro packaging, Linux runtime hardening, and public web-console polish.

Highlights:

• Arch joins Fedora as a first-class GitHub release package target, with refreshed v1.0.1 assets for both distro paths
• Headless labwc startup, preview routing, and Mission Control preview-source labeling are improved
• Mission Control charting is split out and the web shell is hardened against local self-signed HTTPS chunk-load failures
• The web console now pauses polling and live telemetry while hidden, reducing idle browser and host load
• Browser smoke coverage now checks the key public routes against a live Polaris instance
• Trusted Pair diagnostics and trusted-subnet matching are clearer, including IPv6 support
• Client-requested display modes now cap AI/session optimization upshifts instead of being silently exceeded
• Control-shell AI cache handling is less noisy for Steam UI and desktop-style sessions

v1.0.0

First public Polaris release.

Highlights:

• Linux-first host with a dedicated streaming compositor path
• Web UI for Mission Control, library management, pairing, settings, security, and troubleshooting
• Trusted Pair, QR pairing, and manual PIN pairing flows
• Live session preview, runtime telemetry, diagnostics, and quick controls
• Steam, Lutris, and Heroic library import flows
• Nova-aware launch modes, watch mode, and richer session-state integration
• Adaptive bitrate, AI optimizer support, and per-title tuning
