nats-io/nats.net v3.3.0

NATS .NET v3.3.0

on GitHub

Breaking for implementers: INatsJSContext, INatsJSStream and INatsSvcServer gained members (push consumer creation and RemoveEndpointAsync). Anything implementing these interfaces directly, such as a test double, needs updating. Callers are unaffected. Default implementations are not possible while the client targets netstandard2.0.

New:

• Public push consumer API: INatsJSPushConsumer, NatsJSPushConsumerOpts and CreatePushConsumerAsync, CreateOrUpdatePushConsumerAsync, GetPushConsumerAsync and CreateOrderedPushConsumerAsync on the JetStream context and stream. Pull operations on a push consumer throw NatsJSProtocolException (#1231)
• Opt-in case-sensitive header handling via NatsOpts.CaseSensitiveHeaders. Headers stay case-insensitive by default (#1258)
• Service endpoints can be stopped individually with INatsSvcServer.RemoveEndpointAsync (#1255)
• NatsJsonSerializer accepts JsonWriterOptions alongside JsonSerializerOptions (#1253)
• NatsKVPurgeOpts.RetainRecentlyDeletedKeyHistory keeps the history of recently deleted keys when purging delete markers (#1252)

Fixed:

• KV reads on buckets with AllowDirect disabled: GetEntryAsync with a revision threw "Unexpected subject", and deleted or purged keys came back as live Put entries (#1240)

Thanks to @Ivandemidov00 for the push consumer API, @adamjones2 for the service endpoint, serializer and KV purge changes, @jeacott1 for the header handling, and @fresh55 for reporting and fixing the KV read bug.
