v0.7.0

[arif-banai]

JMusicBot v0.7.0

The biggest release yet. This version rebuilds the bot around modern slash commands, introduces a dedicated service layer, adds interactive message components (buttons, pagination, selectable queues/playlists), ships a brand-new desktop GUI with live performance monitoring, adds proxy support, and lands a massive automated test suite.

Highlights

• Full slash command suite (/play, /queue, /np, /playlists, /settings, and many more) with a modern, componentized Discord UX.
• Interactive everything — clickable Now Playing controls, a selectable/movable queue, paginated lists, and interactive playlist & history management.
• New desktop GUI built on FlatLaf, with themes and live audio/system health dashboards.
• Playback history with previous/rewind support and a /history command.
• Playlist favorites and richer playlist browsing.
• Proxy support for Lavaplayer, JDA, and version checks.
• Dependency upgrades across JDA, Lavaplayer, and the YouTube source.
• Huge test-coverage expansion with reusable test fixtures and scenario builders.

Slash Commands (v2)

The bot now ships a complete slash command layer (commands.v2) alongside the classic prefix commands, sharing the same underlying logic.

• Music: /play, /search, /queue, /nowplaying (/np), /playlists, /history, /remove, /seek, /shuffle, /skip
• DJ: /forceskip, /forceremove, /movetrack, /playnext, /pause, /repeat, /skipto, /stop, /volume
• Admin: /settings, /prefix, /setdj, /settc, /setvc, /queuetype, /skipratio, /nplayout, /npbuttons, /clearchannel
• Smart registration: a new SlashCommandRegistry performs hash-based change detection so commands are only re-registered with Discord when they actually change.
• Unified output: an OutputAdapter abstraction (TextOutputAdapters / SlashOutputAdapters) lets the same command logic serve both prefix and slash contexts.

Interactive Message Components

Discord messages are now interactive rather than static.

• Now Playing controls — play/pause, skip, and more directly on the Now Playing message.
• Interactive queue — select, remove, move, play-next, and play-now buttons on the queue embed.
• Interactive playlists — browse, view details, favorite/unfavorite, select, move, and unselect entries, with an "Add all to queue" action.
• Interactive history — re-queue past tracks straight from the /history view.
• Shared pagination — a reusable PaginatedListEmbedUtil / PaginatedListComponents system powers consistent paging across queue, playlists, and history.
• Dedicated interaction listeners (PlaybackControlsListener, QueueInteractionListener, PlaylistsInteractionListener, HistoryInteractionListener, SettingsInteractionListener, NowPlayingCleanupListener, VoiceStateListener).

Now Playing Overhaul

• Configurable layout (full vs minimal) and buttons via /nplayout and /npbuttons.
• Optional progress bar (enables a 10s refresh thread when on).
• Optional YouTube thumbnails.
• Rebuilt MessageFormatter for cleaner metadata and status display.
• Robust message reconciliation and fallback text-channel resolution in NowPlayingHandler.

Playback History

• New PlaybackHistory structure backing previous / rewind functionality.
• /history command with interactive re-queueing.
• Configurable playback.maxHistorySize (default 40, 0 disables history).
• Queue operations that preserve history (stopAndClearQueuePreserveHistory, clearHistory).

Playlists

• Favorites — mark playlists as favorites and surface them first.
• Interactive details view with pagination and async preview loading.
• Select / unselect / move controls for managing playlist contents.

Desktop GUI

An optional, modern desktop interface (disable with gui.enabled = false).

• Built on FlatLaf 3.7 with light / dark / darcula / intellij themes and configurable font size.
• Panels for Status, Performance, System Health, Source Health, Config, Settings, and an Enhanced Timeline.
• Console output is buffered early and replayed into the GUI (TeeOutputStream), with EDT exception logging and safer auto-scroll.

Performance Monitoring

New instrumentation to diagnose stutters and resource pressure:

• PerformanceMetrics, GCMonitor, SystemHealthMonitor, VoiceConnectionMonitor, TrackLoadingMonitor.
• AudioMetricsListener / AudioLoadWrapper (no-op when running headless).
• New performance config for audio buffering: nasBufferMs (default 800) and frameBufferMs (default 2000) to absorb GC pauses.

Proxy Support

• New proxy config block (host, port) plus per-component routing toggles for Lavaplayer, JDA, and GitHub version checks.
• Also configurable via standard -Dhttp.proxyHost / -Dhttps.proxyHost JVM args.
• Backed by a new ProxyUtil. (Marked experimental.)

Channel Management

• New /clearchannel command (owner/admin) with a ChannelClearHelper.
• Configurable commands.clearChannel.deleteLimit (default 50) and ageDays (default 14).

Settings

• New /settings command with an interactive settings panel (SettingsPanelRenderer) for viewing and adjusting per-guild configuration.

Configuration

• Config schema bumped to version 2 with an automatic V1 → V2 migration.
• voice.aloneTimeUntilStopSeconds now defaults to 10 (previously disabled).
• New sections: gui, performance, proxy, commands.clearChannel, plus expanded nowPlaying and playback options.

Dependency Updates

Dependency	From	To
JDA	6.3.0	6.4.2
Lavaplayer / lava-common	2.2.6	2.2.7
YouTube Source	arif-banai fork	dev.lavalink.youtube:v2 1.18.1
JDave	0.1.5	0.1.7
FlatLaf (new)	—	3.7

• Migrated to the upstream dev.lavalink.youtube v2 module for lavaplayer 2.x thumbnail-capable clients (uses AndroidVrWithThumbnail for non-OAuth).

Testing & Quality

• Extensive new unit test coverage across services, commands (v1 & v2), listeners, audio, queue, playlists, config, and utilities.
• Reusable test infrastructure: TestBase, AudioTestFixture, ServiceTestFixture, SlashCommandTestFixture, ListenerTestFixture, and scenario/state builders.
• Improved mojibake (encoding) handling in track titles and autocomplete, with tests.
• Added docs/ARCHITECTURE.md describing the layered architecture.

---

Upgrade Notes

• Config auto-migrates to version 2 on first launch (a backup is created). Review the new gui, performance, and proxy sections in reference.conf if you want to customize them.
• The GUI is enabled by default — set gui.enabled = false for headless/server deployments.
• Slash commands register automatically; allow a short delay for Discord to propagate them.

Amazing work, my friends and I love this bot so we appreciate all the effort!!

[JJ-Coding]

Good stuff, YouTube music works reliably again! New control buttons are nice too.

[SuperOfSrb2]

After the update, the bot doesn't seem to respond to any commands other than stuff like !settings and !about in voice channels. In standard channels it works fine, but you wouldn't want to be switching channels all the time
Slash commands also don't seem to be registering but this isn't as big of a deal
Is anyone else having this issue? How would I fix it?
