Updated Microsoft.Extensions.TimeProvider.Testing from 10.6.0 to 10.7.0.

Release notes

Sourced from Microsoft.Extensions.TimeProvider.Testing's releases.

10.7.0

v10.7.0 graduates the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kubernetes package to stable. The package registers a Kubernetes-aware ResourceQuotaProvider that reads the pod's CPU and memory requests and limits and exposes them to Microsoft.Extensions.Diagnostics.ResourceMonitoring as baseline and maximum quotas, which then feed the request and limit dimensions of the published resource utilization metrics. The companion ResourceQuota and ResourceQuotaProvider types in Microsoft.Extensions.Diagnostics.ResourceMonitoring graduate to stable in the same change so that consumers can implement custom quota providers without taking an experimental dependency.

On the AI side, Microsoft.Extensions.AI.OpenAI moves to OpenAI 2.11.0 and fixes a deserialization bug in ToolJson.AdditionalProperties so that JSON Schema additionalProperties values shaped as sub-schema objects (for example {"type":"string"}) are preserved instead of throwing during deserialization. HostedFileContent.SizeInBytes and HostedFileContent.CreatedAt graduate to stable since both values are consistently available across hosted-file providers, while Purpose and Scope remain experimental as provider-shaped vocabulary. FunctionInvokingChatClient drops a backward-compat path that auto-marked ToolApprovalResponseContent entries with InformationalOnly: true; consumers that need to continue accepting sessions serialized before #​7468 can use the sample ApprovalHistoryNormalizingChatClient middleware added in the test project.

What's New

Adaptive Synchronization Tolerance

The MasterClock sync engine now automatically adjusts its drift correction thresholds based on real-time hardware performance — no configuration needed. On capable hardware the tightest possible tolerances are active; on slower systems the engine relaxes them to prevent constant red-zone corrections.

AdaptiveScale	Green Zone	Yellow Zone	Meaning
1.0	5 ms	25 ms	Optimal — strict defaults active
2.0	10 ms	50 ms	Moderate load — tolerances doubled
4.0	20 ms	100 ms	High load — fully relaxed

The scale increases by 0.5 steps when ≥ 5 red-zone hits occur within a 3-second window, and decreases by 0.5 steps after 8 consecutive seconds in the green zone.

Tighter Default Tolerances

Threshold	Previous	New
SyncTolerance (Green Zone)	20 ms	5 ms
SoftSyncTolerance (Yellow Zone)	100 ms	25 ms

SyncDiagnostics — Runtime Health Check

A new SyncDiagnostics property on FileSource exposes the current adaptive state as a zero-allocation readonly struct. Use it to detect whether the adaptive system has elevated its thresholds, which may indicate a performance issue in a custom effect or processing pipeline.

SyncDiagnosticsSnapshot diag = fileSource.SyncDiagnostics;

if (diag.IsRelaxed)
{
    Console.WriteLine($"Adaptive tolerance active — Scale: {diag.AdaptiveScale:F1}x");
    Console.WriteLine($"Green zone:  {diag.EffectiveSyncToleranceMs:F1} ms  (baseline: 5 ms)");
    Console.WriteLine($"Yellow zone: {diag.EffectiveSoftSyncToleranceMs:F1} ms (baseline: 25 ms)");
    Console.WriteLine($"Red zone hits in window: {diag.RedZoneHitsInWindow}");
}

SyncDiagnosticsSnapshot is a readonly struct — zero heap allocation, AOT-compatible, safe to call from any thread.

WaveDisplayControl — Zoomed-In Line Rendering

When samplesPerPixel < 1.0 (zoomed in past individual samples), the waveform renderer now switches to a connected line style for a cleaner visual. Added SampleToPixel / PixelToSample inline helpers for coordinate conversion.

OwnAudioSharp v3.1.0 Release Notes

Release Date: June 2026 | Requirement: .NET 10.0+

New Features

Optional FFmpeg Decoder Integration

OwnAudioSharp now supports FFmpeg 8+ as an optional, zero-dependency decoder backend. FFmpeg is not bundled — if the system libraries are present they are detected and loaded automatically; if not, the built-in decoders continue to work unchanged. There are no breaking API changes.

• FFmpegConfig class for specifying a custom library search path and querying availability at runtime
• Supports all formats FFmpeg can decode (AAC, OGG, OPUS, M4A, WMA, and more) in addition to the built-in MP3 / WAV / FLAC decoders
• AudioDecoderFactory selects FFmpeg automatically when available and the format is not handled natively
• Full P/Invoke interop layer (FFmpegInterop) with source-generated [LibraryImport] — AOT-safe

// Optional: point to a non-standard FFmpeg location
FFmpegConfig.LibraryPath = "/opt/ffmpeg/lib";

// Check availability before use
if (FFmpegConfig.IsAvailable)
    Console.WriteLine("FFmpeg decoder active");

// No other changes — AudioDecoderFactory picks the right decoder automatically
using var decoder = AudioDecoderFactory.Create("audio.opus", 48000, 2);

MIDI API — Major Extension

SysEx Receive
IMidiInputPort now exposes a dedicated SysExReceived event that delivers complete 0xF0 … 0xF7 frames as a ReadOnlySpan<byte>. The event uses the custom SysExReceivedHandler delegate because Action<ReadOnlySpan<byte>> cannot be used as an event type directly. All platform implementations are zero-allocation in the hot path:

• Windows (WinMM): four rotating 4 KB unmanaged MIDIHDR buffers managed by the driver callback
• macOS (CoreMIDI): 64 KB per-port accumulation buffer that reassembles SysEx frames split across CoreMIDI packets
• Linux (ALSA rawmidi): byte-level state machine with running-status and cross-read fragmentation support; [InlineArray(3)] struct for channel message assembly avoids heap allocation

Virtual MIDI Ports
MidiPortFactory.CreateVirtualInput(name) and CreateVirtualOutput(name) create software MIDI endpoints visible system-wide to other applications and DAWs. SysEx receive is fully supported on virtual ports.

• macOS: MIDIDestinationCreate / MIDISourceCreate + MIDIReceived via CoreMIDI
• Linux: ALSA Sequencer (snd_seq_t) — connectable via aconnect

Hot-Plug Device Monitoring
MidiPortFactory.PortsChanged fires when MIDI devices are connected or disconnected. Activate with StartMonitoring(), deactivate with StopMonitoring().

• macOS: CoreMIDI client notification callback — zero polling, fully event-driven
• Linux: FileSystemWatcher on /dev/snd via kernel inotify

Timestamped Send (macOS)
MacOsMidiOutputPort exposes a Send(in MidiMessage, long timestampNs) overload. CoreMIDI schedules the message at the exact Mach Absolute Time, eliminating OS scheduling jitter. Pass 0 for immediate delivery.
