v3.1.0

What's Changed

This release introduces features to Core (tracing), JetStream (per-message ttls, pinned consumers, subject-based sequence constraints) and KV (per-message ttls, timeout support for put/update operations) and improve the reliability of the client.

Core

• feat(core): tracing - Introduced TraceOptions in PublishOptions, RequestOptions, and RequestManyOptions to enable message tracing with NATS. Trace messages are sent to a traceDestination subject and optionally flagged as traceOnly to avoid delivery and generate trace data only by @aricart in #265
• fix(core): use InstanceType for TE and TD type annotations by @Roseidon in #298
• fix(core): status iterator can now yield a close event signaling that the client closed by @aricart in #277
• refactor(core): remove redundant type assertions in Subscription by @aricart in #293

JetStream

• feat(kv,jetstream)Add support for per-message TTLs in KV and JetStream by @aricart in #281
• feat(jetstream): pinned consumers by @aricart in #263
• feat(jetstream): support for pedantic mode in consumer creation by @aricart in #264 and #275
• feat(js): add support for subject-based sequence constraints. These allow constraints for sequences to be applied to a different using a different subject, simplifying constraints for hierarchical subjects by @aricart in #287
• fix(js): improve handling of 409 status and max_bytes edge cases by @aricart in #286
• fix(js): update tests to reflect changes in 2.11.6 behavior for max_waiting where 409 for exceeded max_waiting errors are not sent to the client when requests have an expires. This means that consumers will rely on heartbeats to pull again by @aricart in #291
• fix(js): improved the typings for DirectBatchOptions types by @aricart in #289
• tests(js): Add test and logic to bypass JetStream checks for bind-only by @aricart in #272
• tests(js): Add timeout tests for JetStream clients and managers by @aricart in #274

KV

• feat(kv,jetstream)Add support for per-message TTLs in KV and JetStream by @aricart in #281
• feat(kv): timeout support for put and update operations by @aricart in #273

Obj

• Update types.ts: clarify timeout in ObjectStorePutOpts by @alexbozhenko in #261

Services

• fix(service): stop iterators when the subscription closes. by @aricart in #288

• Update README.md by @alexbozhenko in #262

Transport-Node

• Introduced NodeTlsOptions and NodeConnectionOptions types to handle Node.js-specific TLS configurations, like rejectUnauthorized. Updated connect, for transport-node, and related logic to support these new options by @aricart in #260

Docs

• doc: add extra link to runtimes to make it more discoverable by @alexbozhenko in #185
• Fix typo in a comment by @williamstein in #266
• Update URL paths for full JetStream examples by @maxdemaio in #267
• fix(doc): runtime was describing Svc (the original name of the type) instead of Svcm by @aricart in #276
• fix(doc): fixed the deno installation command by @LeUKi in #279
• docs: added new types exposed by the current api by @aricart in #278
• updated docs by @aricart in #280

CI

• chore: remove GitHub action workflows and update package versions by @aricart in #290
• chore: add utility for managing module versions by @aricart in #295
