chore(deps): Bump NATS.Net from 2.6.11 to 2.8.0

[dependabot]

Updated NATS.Net from 2.6.11 to 2.8.0.

Release notes

Sourced from NATS.Net's releases.

2.8.0

Happy to announce the NATS .NET 2.8.0 stable release of the 2.8 line. It picks up the NATS Server v2.14 client surface (consumer reset, $JS.FC.* flow-control replies, Consumer field on stream source/mirror, AllowBatchPublish on stream config), ships two breaking changes that landed in the preview cycle, and fixes in-flight message loss on consumer/connection dispose behind an opt-in drain.

A big thank you to all NATS contributors and community members who helped make this release possible. <3

NATS Server v2.14 Features

• ResetConsumerAsync on INatsJSContext and INatsJSConsumer (ADR-60), to reset a pinned consumer's state (#​1126).
• $JS.FC.* flow-control replies are parsed by the JS metadata layer, for streams that publish with the js_ack_fc_v2 flag (#​1127).
• Consumer field on StreamSource and stream mirror config, for pre-created mirror/source consumers (#​1128).
• AllowBatchPublish on StreamConfig (JSON allow_batched), required by streams that opt into fast-ingest batch publishing per ADR-50 (#​1120). The fast-ingest publisher itself lives in orbit.net alongside the existing atomic batch publisher.

Breaking Changes

Subject Validation On By Default (#​1093)

Subjects containing whitespace (space, tab, CR, LF) now throw NatsException. This closes a class of CRLF injection issues from malformed subjects.

Opt out if you rely on legacy subjects that contain whitespace:

var opts = NatsOpts.Default with { SkipSubjectValidation = true };

NKeyPair Removed From NATS.Client.Core (#​1101)

NATS.Client.Core.NKeys and NKeyPair are removed. Signing now goes through the NATS.NKeys package, which lets the nkey/Ed25519 code be versioned independently of the client.

For typical users this is transparent: keep using NatsAuthOpts.NKeyFile, CredsFile, Jwt + Seed, or AuthCredCallback and the client wires up the new signer automatically.

Only direct callers of NATS.Client.Core.NKeyPair need to switch:

// Before
using NATS.Client.Core;
var kp = NKeyPair.FromSeed(seed);
var sig = kp.Sign(nonce);

// After
using NATS.NKeys;
var kp = KeyPair.FromSeed(seed);
var sig = kp.Sign(nonce);

Other Notable Changes

• Server error event (#​745): a new event on NatsConnection surfaces server-side errors to client code.
• Message loss on consumer dispose (#​1085): opt-in drain keeps in-flight messages from being dropped when a consumer or connection is disposed. Enable with:

... (truncated)

2.8.0-preview.3

Third preview of NATS .NET 2.8 completes the nats-server v2.14 feature set for the client. See PRs below for specifics.

This release also includes a fix for in-flight message loss on consumer/connection dispose. The new drain path is opt-in, so defaults preserve current behavior. The dispose ordering refactor touches a hot path though, so please give your workloads a once-over and report anything that looks off.

Opt in:

var opts = NatsOpts.Default with
{
    DrainSubscriptionsOnDispose = true,
    ConsumerDrainOnDisposeTimeout = TimeSpan.FromSeconds(10),
};

Changes:

• Add consumer reset API (#​1126)
• Add $JS.FC support to JS metadata parser (#​1127)
• Add consumer field on stream source/mirror (#​1128)
• Fix message loss on consumer dispose (#​1085)

Full Changelog: nats-io/nats.net@v2.8.0-preview.2...v2.8.0-preview.3

2.8.0-preview.2

Second preview of NATS .NET 2.8 ships nats-server v2.14 support: streams that opt into fast-ingest batch publishing per ADR-50 can now set the new AllowBatchPublish field on StreamConfig (the fast-ingest publisher itself will live in orbit.net alongside the existing atomic batch publisher). Also picks up a Pin ID handling fix for duplicate status headers, the new flat README intro, and assorted CI and test flake fixes.

Changes:

• Add AllowBatchPublish stream config field (#​1120)
• Bump OpenTelemetry and OpenTelemetry.Exporter.OpenTelemetryProtocol (#​1121)
• Fix setting wrong pin id from status header (#​1116) (thanks @​colprog)
• Fix slow-consumer test first-ping RTT flap (#​1115)
• Fix net481 TLS test flakes (#​1111)
• Rewrite README intro (#​1114)

Full Changelog: nats-io/nats.net@v2.8.0-preview.1...v2.8.0-preview.2

2.8.0-preview.1

Happy to ship the first preview of NATS .NET 2.8. The theme of this release is tightening the protocol layer and shrinking the core API surface, so this preview carries two breaking changes. Please try it and report anything odd before we cut the stable.

Package on NuGet: https://www.nuget.org/packages/NATS.Net

Breaking changes:

• Subject validation is on by default. Subjects containing whitespace (space, tab, CR, LF) now throw. This closes a class of CRLF injection issues from malformed subjects. Opt out with SkipSubjectValidation = true on NatsOpts.
• NATS.Client.Core.NKeys and NKeyPair are removed. Signing now goes through the NATS.NKeys package (https://www.nuget.org/packages/NATS.NKeys), which lets the nkey/Ed25519 code be versioned independently of the client.

Also includes protocol size checks (64MB incoming payload cap, in line with nats.js), KV watcher cancellation fix, credential loading state reset on failure, and Pin ID handling improvements.

Thanks to the NATS community who contributed PRs, reviews, and bug reports on this one ❤️

Full Changelog: nats-io/nats.net@v2.7.3...v2.8.0-preview.1

2.7.3

Announcing a new version of NATS .NET client library covering various fixes and a security update on one dependency for NETStandard targets (#​1089) even though the vulnerable API is not used by our library.

A big thank you to all NATS contributors and community members who helped make this release possible ❤️

Breaking Changes

NakAsync Signature Change (#​1081)

The TimeSpan delay parameter has been removed from INatsJSMsg<T>.NakAsync(). The delay must now be passed via AckOpts.NakDelay.

Before (v2.7.2):

await msg.NakAsync(delay: TimeSpan.FromSeconds(5));
await msg.NakAsync(opts, TimeSpan.FromSeconds(5));

After (v2.7.3):

// Option 1: Use the new extension method
await msg.NakAsync(TimeSpan.FromSeconds(5));

// Option 2: Use AckOpts with NakDelay
await msg.NakAsync(new AckOpts { NakDelay = TimeSpan.FromSeconds(5) });

Note: because we also have an extension method, recompiling your project is enough.

AckTerminateAsync TermWithReason (#​1048, #​1081)

AckTerminateAsync now supports an optional termination reason. A new overload and a new TerminateReason property on AckOpts have been added to INatsJSMsg<T>. Implementors of this interface must add the new method.

// New overload
await msg.AckTerminateAsync("processing failed permanently");

// Or via AckOpts
await msg.AckTerminateAsync(new AckOpts { TerminateReason = "processing failed permanently" });

// Extension method shorthand
await msg.AckTerminateAsync("reason", cancellationToken);

Requires NATS Server 2.10.4+.

PinnedClient Validation (#​1063)

Calling NextAsync(), FetchAsync(), or FetchNoWaitAsync() on a consumer with PriorityPolicy.PinnedClient now throws NatsJSException. Use ConsumeAsync() instead.

// This now throws NatsJSException:

* resolves: 1035 - Use ConnectTimeout when awaiting INFO signal by @​ptsteward in https://github.com/nats-io/nats.net/pull/1039

## Slow Consumer Fix
Although we are happy that we believe slow consumer fix will solve a lot of the performance issues under load, please test this release as much as you can since there maybe behavioral changes that might affect your application. Please see #​1041 for more information.

Here are suggested changes after upgrading to 2.7.2-preview.1 or above:

### Observing Slow Consumer Events
In NATS .NET you can watch for slow consumer events by subscribing to `MessageDropped` event on the `INatsConnection` object and set the internal channel capacity using the `SubPendingChannelCapacity` option:

```csharp
await using var client = new NatsClient(
    opts : new NatsOpts
    {
        // Default is 1024, however, this may be too small for
        // high throughput scenarios. 16K is more reasonable for these cases.
        // Tradeoff is more memory usage especially because over 1024 messages
        // the backing array will be allocated on the LOH (large object heap).
        SubPendingChannelCapacity = 16384,
    },

    // This option may be deprecated in the future and set to DropNewest by default
    pending: BoundedChannelFullMode.DropNewest); 

client.Connection.MessageDropped += (sender, args) =>
{
    Console.WriteLine($"Message dropped. Subject:{args.Subject} Pending:{args.Pending}");
    return default;
};

Trade-offs of SubPendingChannelCapacity

Setting	Pros	Cons
Lower capacity (1024)	Avoids LOH allocations	Higher chance of message drops under load
Higher capacity (16384)	Handles burst traffic better	More memory usage, potential LOH allocations

You should watch LOH memory usage and slow consumer events using MessageDropped handler.

Also note that channel doesn't allocate this immediately. The backing array grows twice as much each time there is need for more space.

Differences between NatsClient and NatsConnection

NatsClient sets SubPendingChannelFullMode option to BoundedChannelFullMode.Wait by default which means you won't take advantage of this fix if you're using NatsClient to setup your connection.

If you are using NatsClient this fix won't affect your applications.
... (truncated)

2.7.1

This is a patch fix release for NATS .NET client fixing breaking changes introduced in the previous minor release. With this release errors with transient dependencies that are referencing older versions of the client are corrected by using type forwarding since we moved serialization interfaces to a new 'Abstractions' assembly. We are planning to more other interfaces into the Abstractions assembly and we will make sure the type forwards are in place for those. We also had a fix for an OTel extension due to moving return types to interfaces.

What's Changed

• Fix 2.6/2.7 ABI for serializer interfaces by @​caleblloyd in Fix 2.6/2.7 ABI for serializer interfaces nats-io/nats.net#1032
• Fix OTel INatsJSMsg extension by @​heikkilamarko in Fix OTel INatsJSMsg extension nats-io/nats.net#1031

Full Changelog: nats-io/nats.net@v2.7.0...v2.7.1

Big thanks to @​caleblloyd and @​heikkilamarko for their help finding and fixing these issues for everyone.

You can download this release from NuGet as usual: https://www.nuget.org/packages/NATS.Net/2.7.1

2.7.0

⚠️ This release might create issues with transient dependencies because serialization interfaces are moved to different assemblies. Please use 2.7.1 or later versions where this was fixed with type forwarding.

We are excited to announce a minor release of NATS .NET version 2.7.0 with a lot of fixes and improvements making NATS .NET client easier to use, testing friendly and more robust:

• Improved OpenTelemetry support: Added filtering and enrichment for activities (#​859)
• JetStream publish improvements: Better retry defaults and consistent error handling
• Dependency upgrades: All Microsoft.Extensions packages updated to .NET 8 (improves compatibility, security, and performance)
• Abstractions package: Moved serialization interface into abstractions (#​858) for better modularity/ We will move other interfaces to Abstractions gradually.

Important: Please note, there are also minor breaking changes which might affect dependent applications and sometimes transient dependencies. Application developers should recompile and test their application more rigorously in a non-production environment before deploying to production.

Breaking Changes

• Timeout exceptions: Replaced OperationCanceledException with NatsTimeoutException for timeouts (previously surfaced as cancellations). Update any code catching OperationCanceledException for timeouts.

• ReplyAsync on NatsJsMsg: Now marked [Obsolete]. Use the alternative method instead.

• Serialization interface moved into abstractions: Via PR #​858 ("Move Serialization Interface into Abstractions").

  • This is a structural refactor that relocates the serialization-related interface to a dedicated abstractions layer in the codebase.
  • Why it matters: It improves modularity, maintainability, and separation of concerns (e.g., making it easier to swap or extend serialization without touching core implementation).
  • Impact: This is not a breaking change for end-users (no API surface change is mentioned), but it could affect anyone building extensions or custom serializers that directly reference the old location.
  • Linked issue: #​851

• Fixed KV TTL interface handling (#​854): This brings KV API inline with the design documents. It removed TTL parameters from update calls, which are problematic with buckets with history enabled.

New Features

• OpenTelemetry activity filtering & enrichment
• Improved JetStream publish retry behavior

Bug Fixes

• Fixed KV TTL interface handling (#​854)
• Fixed connection state issues for consume, request, and reply (#​856–858)
• Improved timeout exception handling across client, JetStream, and consumer scenarios

2.6.14

This is a bugfix release with a small but important Subject Validation feature. Subject validation is turned of by default and can be enabled in NatsOpts. It will be enabled by default in a couple of releases down the line, so if you can, please enable it as soon as possible to make sure your applications are not affected. Subject validation makes sure subjects does not have whitespace characters as to not break the wire protocol. Placing spaces in subjects is not valid and well known. We do not expect the new subject validation feature to break any applications. Only being careful here. See #​1017 for more details.

• Add validation for subjects by @​mtmk in Add validation for subjects nats-io/nats.net#1017
• Add Timeout to Object Get Disposal by @​mtmk in Add Timeout to Object Get Disposal nats-io/nats.net#1014

2.6.12

Happy to announce we have a new release of NATS .NET client library version 2.6.12. With this version we are providing several minor bug fixes and improvements as well as a couple of new features we missed out in our previous release supporting NATS Server 2.12: Support for Nats-Expected-Last-Subject-Sequence-Subject header #​1007 and prioritized mode #​1011.
