* Add .NET 10 Target * Release 3.0.0-preview.1 (#1071) - Initial release with .NET 10 target - Also dropped .NET 6 target * Clean up NET6 and optimize NETSTANDARD (#1072) * Clean up NET6 and optimize NETSTANDARD - Remove .NET 5/6/7 from `#if` directives and build - Delete commented-out file - Optimize NETSTANDARD encoding polyfills used in hot paths to eliminate intermediate array allocations - Fix `PeriodicTimer` CancellationTokenRegistration leak - Add encoding polyfill benchmark * Fix `PeriodicTimer` cancellation to prevent leak - Ensure static lambda used to avoid allocation. * Update DI package dependencies and documentation (#1075) Switch project dependency from `NATS.Net` to `NATS.Client.Simplified` for better modularity. Add `NATS.Extensions.Microsoft.DependencyInjection` to `NATS.Net` dependencies. Update documentation to include comparisons between `NATS.Extensions.Microsoft.DependencyInjection` and `NATS.Client.Hosting`, clarifying usage scenarios. Add new DI guide to advanced docs. * Release 3.0.0-preview.2 (#1091) Merged main * Add message context to serialization interfaces (#1082) * Add support for optional NATS headers in serialization/deserialization * Make `Serialize` method header-aware and add unit tests for header serialization logic * Add recursion guard to prevent infinite loops in default interface methods for `Serialize`/`Deserialize`, update tests and examples accordingly * Fix `Content-Type` header deserialization by updating to use `StringValues` * Fix NuidTests flap * Improve NuidTests stability * Remove old default methods * Remove `IDictionary` implementation from `NatsHeaders` * Add INatsSerializeWithHeaders * serializer: remove unnecessary obsolete warning pragmas The CS0618 suppressions were leftover from the DIM approach where interface members were marked obsolete. No longer needed with the separate interface design. * tests: add serialization extension and ABI checks Add unit tests for NatsSerializationExtensions covering both the header-aware path and the fallback path for serialize and deserialize. Make the ABI check program assert correctness instead of just printing, including the new WithHeaders interfaces. * serializer: replace WithHeaders with WithContext interfaces Replace INatsSerializeWithHeaders<T>/INatsDeserializeWithHeaders<T> with INatsSerializeWithContext<T>/INatsDeserializeWithContext<T>, passing a NatsMsgContext struct that carries Subject, ReplyTo, and Headers. This gives serializers access to the full message envelope, enabling subject-based dispatch and reply-to inspection without requiring further interface changes in the future. Also fixes the null-headers asymmetry in the extension methods: both Serialize and Deserialize now always dispatch to the context overload when the interface is implemented, regardless of whether Headers is null. * Revert "Improve NuidTests stability" This reverts commit 42b8cbd. * Revert "Fix NuidTests flap" This reverts commit dcc3588. * docs: fix stale DIM references and update serialization docs Remove incorrect DIM claims from serialization docs, rewrite the headers section to describe the WithContext interface design. Clean up NativeAot example that had leftover INatsHeaders parameter overloads from the old DIM approach. Restore dropped <returns> doc comment on INatsDeserialize<T>.Deserialize. * headers: drop read-only state The read-only flag was set on NatsHeaders before passing to publish to catch accidental mutation after publish. It was a weak guarantee since headers are copied to a byte buffer synchronously inside CommandWriter, so post-publish mutation cannot affect wire data anyway. Removing it lets serializers implementing INatsSerializeWithContext<T> mutate headers (e.g. set Content-Type) during serialization, which was otherwise blocked by ThrowIfReadOnly. Telemetry's SetOverrideReadOnly escape hatch is no longer needed and uses the normal indexer instead. * tests: add net10.0 TFM and improve ABI checks Add net10.0 target to CoreUnit, Core, and Core2 test projects. Add CheckAbiOld control project that runs against the old NuGet version to prove type forwarding works by contrasting assembly versions. Centralize the old NuGet version in Directory.Build.props and make the run script assert loaded assembly versions. * tests: fix NU1510 package pruning errors on net10.0 Condition System.Net.Http and System.Text.RegularExpressions package references to net481 only, where they are actually needed. On net10.0 these are built-in and NuGet's package pruning treats the unnecessary references as errors. * serializers: address context review feedback - NatsMsgContext: require Subject via constructor; drop init setters so netstandard shim for IsExternalInit is no longer needed. - Add INatsSerializerWithContext<T> as a combined interface mirroring INatsSerializer<T>, simplifying class declarations for context-aware serializer+deserializer pairs. - Built-in NatsUtf8PrimitivesSerializer, NatsRawSerializer and NatsJsonContextSerializer now implement INatsSerializerWithContext<T> and propagate the context through _next when delegating. Without this, chaining a built-in with a context-aware leaf silently dropped context at the leaf. - Document NatsHeaders thread-safety: not safe to share across concurrent publishes, since readonly-locking was removed. - Document that header-mutating serializers must get non-null headers from the caller; the library does not allocate on their behalf. - Add chain-propagation tests for serialize and deserialize paths. * sln: remove x64/x86 platform noise * Release 3.0.0-preview.3 (#1113) * Use System.Threading.Lock on NET9_0_OR_GREATER (#1118) * core: use System.Threading.Lock on NET9_0_OR_GREATER * core: fix reentrant lock in PublishToClientHandlersAsync * bench: add lock and publish runtime comparison benchmarks * Release 3.0.0-preview.4 (#1123) * Release 3.0.0-preview.5 (#1130) * Release 3.0.0-preview.6 (#1141) * di: clarify package descriptions for NuGet [no ci]

Preview release on the 3.0 line bumping version to 3.0.0-preview.6. Brings in everything merged to main since preview.5 via the latest release/3.0 sync: a new server error event on
NatsConnection, slnx solution-format migration, README and example docs additions, and a CI matrix bump to nats-server v2.12. No 3.0-only changes.From main:
Note for reviewer: Windows non-net8.0 CI is flapping on
TlsPreferTest,Utf8SubjectMockServerTest, andPingCancellationTest. Linux and Windows net8.0 are green. The pattern correlates with #745 (now in this release), but the failures look like a test-side sync/timing issue rather than a runtime regression: static read of #745 says no-op for the TLS path, and the test relies on a tight race between the server reading the client's first byte and the client tearing down on a TLS-upgrade failure. Tracked in #1142.
