v1.21.0

What's Changed

This release slightly changes the behavior of consumers under the new consumer API for fetch() and next(). These operations are now succeptible to consumer deleted type errors. Since these operations are expected to finish at some point (when the number of requested messages is retrieved or when the operation expires) it seems appropriate to telegraph these errors. If your service expects to recover, it can re-issue the next() or fetch request again. For consume(), a new option was added abort_on_missing_resource which instructs the client to cancel if it detects that the stream or the consumer are gone. By default the client will attempt to consumer again.. These options are rejected for order consumer. For more information see #667

Also notable is the addition of a bind option for consume(), fetch(), and next(). This option will NOT check the status of the consumer or if there's an error during a request for messages. Note that in most cases if the consumer is deleted these will surface as heartbeats missed on the consumer status. For fetch() and next() these will result on no messages. Note that when this option is issued the client cannot provide a more precise status. Note that this option is not applicable to ordered consumers. For more information see #668

v1.18.0

What's Changed

The most notable features in this release are:

• More reliable JetStream simplified consumers
• A new connect option noAsyncTraces which greatly improves the performance of request reply and JetStream publishers. This option is opt-in, so please read about it below.

Core NATS

• [FEAT] sync iterator utility syncIterator() by @aricart in #602
• [FEAT] [PERF] added connect option noAsyncTraces to disable async trace extra information on requests - this significantly improves performance but makes request failures harder to trace. This option is false by default - to increate performance, you must set it to true. Note this also improves JetStream publisher performance as those are implemented as requests by @aricart in #622 and #627
• [FEAT] [EXPERIMENTAL] exposed a mechanism to force a reconnect by @aricart in #632
• [FIX] added last() to MsgHeaders to retrieve the last value in the case that the header may be repeated multiple times. Made JetStream direct apis read last header value. Fix #586 by @aricart in #619

JetStream

• [FEAT] [JETSTREAM] [OS] ObjectStore compatibility and tests by @Jarema in #604 and #605
• [FEAT] [JETSTREAM] added creation option to nc.jetstreamManager() to prevent checking if the JetStream API is available. by @aricart in #607
• [FIX] [JETSTREAM] Made simplfied consumers significantly more resilent - ordered consumers can now report status() changes by @aricart in #615
• [FEAT] [JETSTREAM] [KV] [OS] kv and os compression by @aricart in #625 and #631
• [FEAT] [JETSTREAM] added reason to JsMsg#term - this feature requires 2.11.0 by @aricart in #630
