DisCatSharp Release Notes

   - Fixed `RingBuffer<T>.CopyTo` to respect the `index` parameter and validate that enough free slots exist before copying, preventing silent data corruption.
   - Hardened gateway dispatch: all `GuildsInternal` indexer accesses now use `TryGetValue` guards to prevent `KeyNotFoundException` on late-arriving or missing guild payloads.
   - Synchronized session state during reconnect under `_sessionStateLock` to close a TOCTOU race where `OnHelloAsync` could read a partially-cleared session ID and produce a malformed RESUME payload.
   - Fixed heartbeat skipped-beat counter reset from a no-op `Interlocked.CompareExchange` to `Volatile.Write`, and cancels the old heartbeat loop before starting a new one to prevent task leaks across reconnects.
   - Null-guarded `GetSocketLock` to return `null` instead of throwing before the WebSocket is fully initialized.
   - Made `ReadyGuildIds` thread-safe via a dedicated lock and an atomic `SetReadyGuildIds()` mutator; dispatch now calls the mutator instead of writing directly to the backing set.
   - Narrowed broad `catch (Exception)` blocks to specific exception types (`JsonReaderException`, `ArgumentOutOfRangeException`) in all seven Discord exception wrapper types and `Utilities`.
   - Replaced `Stream.Read` with `Stream.ReadExactly` in `MediaTool` to prevent silent partial reads.
   - Eliminated a redundant `DateTimeOffset` → `DateTime` → `DateTimeOffset` round-trip in `Formatter`, preserving UTC offset fidelity.
   - Added a defensive copy on `AttachmentsInternal` in `DiscordMessage.Attachments` to prevent external callers from mutating cached message state.
   - Capped REST `retry_after` to 3 600 s to guard against adversarially large values from misbehaving proxies or rogue buckets.
   - Linearized concurrent bucket enumeration in `RestClient` with a `.ToList()` snapshot before iteration to prevent `InvalidOperationException` under concurrent request pressure.
   - Fixed `SocketLock.ContinueWith` calls to use `CancellationToken.None` and `TaskScheduler.Default`, preventing ambient sync-context capture and potential deadlocks in UI/ASP.NET contexts.
   - Added `DiscordConfiguration.Validate()`, called from `ConnectAsync` before any network I/O, which throws `InvalidOperationException` when `ShardId ≥ ShardCount`.
   - Clamped `LargeThreshold` to the Discord-specified bot range (50–250) in `DiscordConfiguration`; values outside the range are silently clamped on assignment.
   - Added non-negative validation for `ShardId` and positive validation for `ShardCount` in `DiscordConfiguration` property setters.
   - Audited `NullValueHandling` across 51 serialized properties in 19 entity files: corrected 25 from `Include` to `Ignore` on fields Discord never reads as explicit `null`; preserved `Include` on 26 fields where `null` carries a distinct semantic (ungrouping channels, disconnecting from voice, clearing timeout/gradient/incident restrictions, null-as-boolean role tags, and unicode-vs-custom emoji disambiguation).
   - Fixed `DiscordMember.BanAsync` and `UnbanAsync` to route through `ApiClient` directly, consistent with all other member REST operations.
   - Renamed `deleteMessageDays` to `deleteMessageSeconds` on `DiscordMember.BanAsync` and all `DiscordGuild.BanMemberAsync` overloads; removed the legacy days-to-seconds compatibility shim — the API has always accepted seconds. **Note:** positional callers passing day values must be updated manually; named-argument callers are handled by `DCS1102`.
   - Padded log-level labels to eight characters in `DefaultLogger` for consistent column alignment across log lines.
   - Fixed `DiscordEventArgs` scoped service scope to be properly disposed after event dispatch, preventing scoped service leaks on high-volume bots.

   - Overhauled presence caching and added follow-up regression coverage around gateway cache behavior.
   - Added Discord parity updates for store, entitlement, SKU, guild powerup / applied boost, application, audit-log, automod, message-type, and OAuth scope surfaces.
   - Fixed interaction response posting, soundboard cache refresh/list behavior, duplicate application-command execution logging, and several gateway/store dispatch follow-ups.
   - Removed .NET 8 support and aligned the core package with the current target framework matrix.
   - Reworked built-in Sentry telemetry around a per-client diagnostics sink with breadcrumbs, structured tags, better grouping, scrubbed file payload attachments, release/PDB upload support, and package-root stack frame rewriting for code mappings.
   - Added package-level diagnostics participation for built-in extensions and hosting paths, including origin tagging for upstream Lavalink failures.
   - Added gateway telemetry for unknown opcodes, disconnect/session lifecycle, and suppressed dispatch exceptions, plus follow-up fixes for wrapped exception filtering, preserved route-specific grouping, and shard-specific sink metadata.
   - Adjusted Sentry environment tagging so local stable source builds report as `dev` while CI stable builds continue reporting as `production`.
   - Removed the separate `ReportMissingFields` telemetry switch so schema-drift diagnostics now follow `EnableSentry` directly.
   - Prevented the temporary sharded gateway-info client from reusing the parent telemetry sink and emitting spurious session-ended events.
   - Made `DiscordApplicationCommandLocalization.ValidLocales` a static `FrozenSet<string>` for O(1) lookup and zero per-instance allocation.

DisCatSharp.Attributes Release Notes

   - No major API additions.
   - Package metadata and target framework alignment were updated alongside the wider .NET 8 removal work.

DisCatSharp.ApplicationCommands Release Notes

   - Added dedicated `SlashCommandChecksFailed` and `ContextMenuChecksFailed` events with new event args for modern checks-failed handling.
   - Updated command error flow to use dedicated checks-failed events instead of the older errored-event-only pattern.
   - Included follow-up fixes and regression coverage around application-command checks-failed behavior and execution logging.
   - Added diagnostics-sink reporting for application-command execution, registration, and autocomplete failure paths.
   - Fixed command equality change detection: defensive copies for both source and target, type-based matching for entry points and context menus, and explicit `Optional` clearing for unchanged option fields.
   - Fixed entry point (launch) command registration so it flows through normal create/overwrite/unchanged detection instead of being unconditionally re-created on every startup.
   - Strip built-in localizations from the entry point command when `EnableLocalization` is disabled.
   - Added `RegisterEntryPointCommand()` on `ApplicationCommandsExtension` so consumers can configure entry point properties (description, handler type, contexts, integration types) without hardcoding them.
   - Replaced three wasteful `new ServiceCollection().BuildServiceProvider()` allocations with a shared `EmptyServiceProvider.Instance` singleton.
   - Hardened `ChoiceProvider.Services` with a backing field and `InvalidOperationException` guard when accessed before initialization.
   - Fixed bare `catch` blocks to use filtered `catch (Exception ex)` for proper debugger break behavior.
   - Fixed unsafe `int`/`ulong` casts to use `Convert.ToInt32`/`Convert.ToUInt64` for safe numeric conversion.
   - Normalized `ToLower()` calls to `ToLowerInvariant()` for culture-independent command name handling (including `SlashCommandGroupAttribute`).
   - Improved choice value comparison with numeric normalization (`AreChoiceValuesEqual`) to avoid false change detection between `int`/`long`/`double` representations from JSON.
   - Rewrote `DeepEqualOptions` to collect all option mismatches with per-field diagnostic messages instead of returning on the first difference.
   - Added thread-safe snapshots for public collection properties (`GlobalCommands`, `GuildCommands`).
   - Isolated `resultCommands` from the input `updateList` to prevent mutation of caller-provided data.

DisCatSharp.CommandsNext Release Notes

   - No notable feature changes.
   - Package alignment was updated as part of the .NET 8 removal and current framework support refresh.
   - Added diagnostics-sink reporting for command execution failures.

DisCatSharp.Interactivity Release Notes

   - Fixed `ComponentCollectRequest.Collected` never being initialized, which caused `NullReferenceException` on any component collect operation.
   - Replaced non-thread-safe `Dictionary` in `ComponentPaginator` with `ConcurrentDictionary` to prevent race condition corruption during concurrent pagination.
   - Added try-catch blocks around all fire-and-forget `Task.Run` calls in `Paginator` and `Poller` to prevent silent exception swallowing.
   - Fixed `CancellationTokenSource` leak in `GetCancellationToken` by registering a self-disposal callback on the token.
   - Fixed `InteractionPaginationRequest.GetPageAsync` so navigation buttons are properly disabled for single-page pagination and boundary conditions.
   - Removed broken followup-without-ACK path in `ComponentEventWaiter.Handle` that caused Discord API 400 errors on non-matching interactions.
   - Eliminated shared mutable `_builder` field in `ComponentPaginator`; each pagination response now uses a local builder to prevent concurrent corruption.
   - Aligned `PaginationButtons` default custom IDs with their declared constants so custom ID matching works correctly.
   - Removed spam followup messages in `ModalEventWaiter.Handle` for every non-matching interaction event.
   - Fixed dispose-race in `Paginator` and `Poller` where `_client` was set to null before pending `Task.Run` could complete, causing `NullReferenceException`.
   - Replaced reflection-based event lookup in `EventWaiter<T>` with explicit subscribe/unsubscribe delegates for the three known event types; reflection kept only as fallback for the dynamic `WaitForEventArgsAsync<T>` / `CollectEventArgsAsync<T>` public API.
   - Replaced reflection-based event lookup in `ReactionCollector` with direct `+=` / `-=` event subscription matching the pattern `Paginator` and `Poller` already use.
   - Added `lock()` guards around non-atomic read-modify-write operations on `ConcurrentHashSet` in `ReactionCollector` and `PollRequest` to prevent race conditions losing reactions or votes.
   - Fixed multiple enumeration of `IEnumerable<Page>` in `SendPaginatedMessageAsync` / `SendPaginatedResponseAsync` by coercing to `IList<Page>` upfront.
   - Added empty-pages guard (`ArgumentException`) in pagination methods instead of letting `pages.First()` throw an unhelpful exception.
   - Removed dead code `HandleInvalidInteraction` method and unused `_componentInteractionWaiter` / `_modalInteractionWaiter` fields along with their suppressions.
   - `IPaginator` now extends `IDisposable` so paginators held via the interface can be properly disposed.
   - `InteractivityExtension` now implements `IDisposable` with a `_disposed` guard that disposes all nine internal components (waiters, paginators, poller, collector).
   - Added double-dispose guards with `_disposed` flags to `ComponentPaginator`, `PaginationRequest`, `PollRequest`, `ReactionCollectRequest`, `Paginator`, and `Poller`.
   - Replaced unnecessary `await Task.Yield()` calls in `PaginationRequest` with `Task.FromResult` / `Task.CompletedTask`.
   - Renamed confusing `_behaviorBehavior` field to `_buttonBehavior`.
   - `InteractivityHelpers.Recalculate` now throws if all pages lack embeds and preserves content-only pages in the output.
   - Stored `CancellationTokenRegistration` in `ComponentMatchRequest` and `ModalMatchRequest` for proper lifecycle tracking.
   - Added diagnostics-sink reporting for waiter, paginator, poller, and collector exception paths.

DisCatSharp.Common Release Notes

   - No dedicated end-user feature changes.
   - Shared framework/package alignment was updated with the rest of the solution.

DisCatSharp.Lavalink Release Notes

   - Fixed a regression affecting player updates when switching the bot's voice channel while using Lavalink.
   - Included follow-up Lavalink session/internal cleanup and removed obsolete archived Lavalink v1 sources from the maintained tree.
   - Added diagnostics-sink reporting for Lavalink REST, websocket, and connection failures with upstream-origin tagging to distinguish Lavalink server issues from library faults.

DisCatSharp.Voice Release Notes

   - Fixed voice/lavalink integration regressions around channel switching.
   - Voice native packaging/build settings were refreshed with the wider framework alignment changes.
   - Added diagnostics-sink reporting across voice sender, receiver, keepalive, disconnect, and native-loading failure paths.

DisCatSharp.Experimental Release Notes

   - Stabilized autocomplete interaction value handling.
   - Added documentation/supporting work around newer experimental search-related behavior.

DisCatSharp.Configuration Release Notes

   - No standalone package-specific API additions.
   - Configuration-related framework alignment was refreshed with the rest of the solution.

DisCatSharp.Hosting Release Notes

   - Added diagnostics-sink reporting for hosted-service startup and extension-initialization failures.
   - Hosting package alignment was updated as part of the current framework support refresh.

DisCatSharp.Hosting.DependencyInjection Release Notes

   - No notable feature changes.
   - Dependency injection/hosting package alignment was updated as part of the current framework support refresh.

DisCatSharp.Analyzer Release Notes

   - Reworked the analyzer/tooling stack into a NuGet-first workflow with real xUnit/Roslyn regression coverage.
   - Added `DCS2101` as a application-command migration analyzer/code fix with rewrite, split, and manual migration modes..
   - Added `DCS2101` to an error because leaving legacy checks-failed logic on errored events can break consumers.
   - Added `DCS1101`, a presence migration analyzer/code fix for moving supported manual `DiscordClient.Presences` filtering and direct lookup shapes to `DiscordClient.GetPresences(userId)`.
   - Improved `DCS0201` so the override fixer can update `DiscordConfiguration` across project documents.
   - Updated analyzer packaging so `DisCatSharp.Attributes.dll` is bundled with the analyzer package for Roslyn runtime loading.
   - Added analyzer authoring documentation, diagnostic family guidance, release tracking files, and release workflow support for publishing `DisCatSharp.Analyzer`.
   - Added `DCS1102`, a ban-parameter migration analyzer/code fix: detects `deleteMessageDays:` named arguments on `BanAsync`/`BanMemberAsync` and renames them to `deleteMessageSeconds:`, multiplying integer literals by 86400 automatically.
