Changelog

The reference version is 0.5.2. Older entries describe behavior at their release dates. See the README and documentation index for current usage and validation.

0.5.2

• Translate maintained documentation, configuration descriptions, diagnostics, scripts and test output into English. Rename the text installation guide to INSTALL.txt and update package paths and links.
• Keep English as the default UI and preserve automatic Korean translation with a usable LCKR/LCKRL font. Store optional translations separately from English UI text.
• Preserve actual device names, endpoint IDs, microphone selections and existing configuration. Use device aliases only when the selected font lacks the required glyphs.
• Regenerate the English banner and settings previews, and validate both distribution archives for English text, links and matching DLLs.
• Update project, plugin and mod manager versions to 0.5.2 and align installation instructions and archive filenames.

0.5.1

• Reuse voice queues across silence, speech and mute transitions within one output session. Synchronize queue resets with in-progress writes and rendering to prevent stale voice playback.
• Reapply saved Windows application output policies at startup. Apply original-output and explicit-device policies even when saved and initial values match; preserve the initial backup and retry failures.
• Use atomic state changes to discard silent input queues without waiting for the output render lock. Normal mute transitions remain synchronized with output submission.
• Calculate player-to-playback-source associations once per frame instead of searching all players for each source.
• Pan mono callback voice toward its speaker. Preserve stereo callbacks because Unity may already have applied spatial processing.
• On 2026-10-25, the startup-fix source passed 47 basic tests, 16 package checks, 29 Unity synthetic checks and three loopback LAN configurations with all 1,498 synthetic voice frames decoded.
• Verified 44.1/48kHz silent playback and reconnection on four output endpoints, plus preview samples and nonzero levels on two inputs. Actual listening quality and internet multiplayer require separate checks.
• Passed 30 output policy, shutdown and recovery conditions across ten game processes. Restarts with original output, saved explicit devices and Windows default aligned active sessions after initialization without another selection.
• Updated the README, installation guide, configuration example and distribution materials to match features and validation scope.

0.5.0

• Added an MIT license for the original mod source and included it in distribution ZIPs.
• Added transmit microphone selection and an input-level meter to the F8 Microphone Input tab. Preview uses temporary capture before voice connection; the default follows the game's microphone setting.
• Disable separate voice device selection when separation is off and play voice through the selected game output.
• Show the current Windows default device in output lists and clarify status/refresh controls. Removed unused device ID copying.
• Refined F8 accents, panel borders, toggle states and Clear Voice details. Updated both documented settings captures to the same current Unity UI, resolution and language.
• Preserve game mute and hearing restrictions in separated voice. Improved Clear Voice lifetime management and F8 Esc input isolation.
• Use concise English BepInEx status messages and reduce repeated logging.
• Updated the README, installation instructions, mod manager materials and settings images for the current workflow.

0.4.0

• Fixed Esc closing F8 settings while also opening the game's pause menu. Restore original input action states when closing settings.
• Fixed Windows PowerShell 5.1 encoding of Korean filenames and manager manifest descriptions.
• Generate a separate -modmanager.zip for Gale, r2modman and Thunderstore Mod Manager local imports, including name, version, BepInExPack dependency and icon without existing profile settings.
• Removed a fixed Gale profile path from the build; accept the build API DLL through -LethalConfigPath.
• Automatically validate archive paths, contents, metadata, icon, DLL versions and matching DLLs across both distributions.
• Shortened the README around features and installation and separated development instructions. Updated the manager description, icon and banner to reflect actual mod behavior.
• Added optional mono Clear Voice, disabled by default. Activation changes require restarting the game.
• Bypass noise suppression, RNNoise, AGC and AEC/AECM on transmit samples; run voice detection on a separate copy.
• Allow Opus targets from 6 to 300kbps, defaulting to the game's mono maximum of 300kbps, and display observed encoder values.
• Added send/receive FEC, enabled by default and adjustable live with bitrate while active. PLC remains enabled when FEC is off.
• Extend the unoccluded normal receive filter from 10 to 20kHz while preserving radio, occlusion, underwater, distance and direction settings.
• Preserve mono, 48kHz, 20ms frames and the existing protocol; enforce 900-byte payload and 1,024-byte relay packet limits.
• Added Output and Clear Voice tabs in F8 and updated LethalConfig, configuration examples and instructions. Restore original voice if patching fails.
• Passed 34 basic tests, 22 synthetic checks in an isolated Unity copy and three two-process LAN configurations. All 1,514 received synthetic frames decoded; actual microphone and listening checks remain separate.
• Documented standalone Clear Voice, setting application timing, host/client differences and troubleshooting, distinguishing current checks from earlier device records.

0.3.0

• Added side-by-side game and voice output lists in F8 with independent saved selections.
• Route game audio through Windows per-application policies, preserving music, effects and the game's mixing, volume and spatial processing without changing system defaults.
• Default game output to the original application output. Restore previous policies on original-output selection or normal shutdown, and attempt crash recovery at the next launch.
• Restore previous settings on device errors or partial role failures. Discover devices and change application outputs in the background.
• Added game output selection in LethalConfig and separate game/voice device ID copying in F8.
• Preserve existing voice configuration keys and defaults. Output buffer and voice volume affect separated voice only.
• Passed 29 basic tests including output selection/restoration, rollback and recovery record preservation. Actual game output switching and listening still required an environment with active devices.

0.2.2

• Removed Windows default communications output from device selection. Default to Windows default output and preserve old communications selections by resolving their endpoint IDs.
• Fall back to Windows default output if the old communications endpoint is unavailable; retain disconnected explicit IDs for reconnection.
• Added 10ms slider ticks and reference labels at 20, 50, 100, 150 and 200 in F8.
• Added a matching 20-200ms slider with 10ms steps in LethalConfig.
• Normalize saved output buffers to the nearest 10ms and apply changes without restarting.
• Added a banner, environment badges, settings previews, FAQ and collapsible development guidance to the README; organized text installation instructions with numbered sections.
• Added Output.DeviceName to the example and corrected descriptions of output buffers, maximum queues, reconnection and spatial-effect validation to match code.
• Added a document index and validation reference; include documents and presentation images in distribution ZIPs.
• Reworked the ZIP README and contents for installers, fixed ZIP-relative links and expanded update, removal, reset and troubleshooting guidance.

0.2.1

• Added short Korean installation instructions to the distribution ZIP.
• Renamed the mod to Lethal Voice Router, including the F8 title and LethalConfig display name.
• Aligned DLL, project, installation-folder and ZIP names with LethalVoiceRouter.
• Preserved the plugin GUID and io.lethalloopback.cfg filename so existing configuration continues to work.

0.2.0

• Replaced F8 with Unity UI/TextMeshPro matching the game.
• Use the game's 3270 font, checkbox and border sprites, white sliders and orange selection accents.
• Reference font3270_Regular_SDF from installed LCKR/LCKRL without copying or distributing font files.
• Use the game's default font and English UI without LCKR/LCKRL.
• Arrange devices and controls in two areas and adapt the window to the screen aspect ratio.
• Use a separate input system so F8 interactions do not click game menus behind it.

0.1.1

• Moved settings and input handling to an independent runtime object outside the BepInEx loader, starting after scene load.
• Read F8 immediately after Input System updates and prevent repeat toggling while the key is held.
• Added device-name dropdowns, volume, buffer, shortcut and an open-settings button to LethalConfig 1.4.6.
• Apply LethalConfig changes without restarting the game.
• Distinguish devices with duplicate names and preserve disconnected endpoint IDs.

0.1.0

• Route other players' voices to a separate Windows output device.
• Configure output devices, volume, buffer length and failure behavior in F8.
• Track default output and communications devices and reconnect after errors.
• Discard stale buffers on departure, playback-source reuse or output-device changes.
• Use installed playback devices without external executables or virtual audio drivers.
