SDK Release Notes

NCBC-3863: Performance problems and timeouts fixes during rebalance when the cluster contains non-KV nodes.

NCBC-3832: Query timeout set to exceed 100 seconds is now respected.

NCBC-3818: QueryErrorContext Statement parameter is now set properly.

NCBC-3842: Newtonsoft deserializing UTF8 surrogate pairs fixed for exceptions and buffer overflow.

NCBC-3849: Orphaned responses now sent to metrics for untraced operations.

NCBC-3850: Timeouts now recorded to metrics in ClusterNode.ExecuteOp.

NCBC-3852: TryReadMutationToken header length check.

NCBC-3854: Improvements made for LightweightStopwatch unit test.

NCBC-3876: CancellationTokenSource is not disposed when returned to pool on legacy frameworks.

NCBC-3839: Updated packages based on BlackDuck scan.

NCBC-3710: Included operation outcome tag in operation metrics.

NCBC-3837: Provide easy configuration to exclude duplicative metrics from OpenTelemetry.

NCBC-3817: Vulnerability in System.Text.Json 8.0.0 is fixed.

NCBC-3821: Updated CouchbaseNetClientReleasedVerison to 3.6.2.

NCBC-3726: Applied some miscellaneous performance optimizations to transcoders.

NCBC-3795: Reduced duplicate operation handling code in ClusterNode.

NCBC-3791: BucketConfig version used to be compared against the latest applied config, not the latest one received.

NCBC-3698: Manually setting ScopeName and/or CollectionName in the CollectionQueryIndexManager API’s options will now throw an InvalidArgumentException. Previously, the SDK was ignoring the ScopeName and CollectionName in options, instead of throwing InvalidArgumentException as per RFC.

NCBC-3780: Transactions: QueryContext is now copied when retrying SingleQueryTransactions.

NCBC-3798: VectorSearch: Passing in empty vectors now throws InvalidArgumentException

There is an edge case that can cause high CPU usage against Couchbase Server 7.6 and later. Users are advised to upgrade to 3.6.1.

NCBC-3572: For management services, CancellationTokens are now more accurate to the operation’s lifetime.

NCBC-3702: Stellar client: Use DefaultSerializer as default at Cluster level

NCBC-3760: Fixed an issue regarding passing an X509CertificateFactory in ClusterOptions.

NCBC-3768: Aligned Boolean search API to RFC.

NCBC-3775: IndexAlreadyExists is now properly thrown.

NCBC-3785: Transactions: DocumentMetadata deserialization fixed.

NCBC-3789: Updated Release version tag in SDK Directory.Build.Props.

NCBC-3794: Removed infinite loop in ConfigPushHandler, which was causing high CPU usage.

NCBC-3788: Support added for base64 encoded vector types.

NCBC-3771: Refactored RetryOrcestrator for Data Service operations to be clearer.

NCBC-3792: Optimize for larger InFlightOperationSet for high latency connections.

NCBC-3796: Updated local build version to 3.6.0.

NCBC-3797: Updated `VectorSearch’s InterfaceStability to Committed.

Microsoft CVE on GitHub

NCBC-3817: Upgrade System.Text.Json to patched version.

NCBC-3811: Backports ConfigPushHandler fixes to 3.5 branch (See also NCBC-3791, NCBC-3794).

NCBC-3745: MultiplexingConnection will throw a SocketNotAvailableException if disposed.

NCBC-3756: Handle empty VBucketMap in server config.

NCBC-3758: Fixed regression where PersistentQueue was not dequeueing items in original FIFO order.

NCBC-3764: Fixed issue where GetAnyReplica / TaskHelpers.WhenAnySuccessful could potentially cause deadlocks using the .NET Framework.

NCBC-3769: SDK will now adapt to new cluster topology if only a port has changed (as in some Alternate Address configurations).

NCBC-3772: Fixed a regression where configs were being applied to buckets they did not belong to, including cluster-level config.

NCBC-1622: Snappy Compression — using the Snappier library — is now merged into the main SDK.

NCBC-3738: Support added for scoped eventing functions.

NCBC-3746: Performance optimizations added to ArrayExtensions.

NCBC-3759: ExceptionDispatchInfo was being used to capture and rethrow the Exception stack trace at the time the exception was originally caught. ClusterContext bootstrap is now used to track per-node bootstrap errors, using ExceptionDispatchInfo instead of Exception. This may result in more accurate stack traces now or in future runtimes.

NCBC-3770: Reduced the amount of DEBUG logging around Config Push — the additional information is now logged at TRACE level.

NCBC-3690: FIT Management: Implement Scoped Search Index Management.

NCBC-3699: FIT Query: QueryOptionTest failures fixed.

NCBC-3700: FIT KV: New Subdoc errors fixed.

NCBC-3703: FIT Stellar: InvalidArgument and DocumentTooDeep now handled.

NCBC-3716: Fixed a regression in KV throughput against Trinity during rebalances.

NCBC-3720: ClusterChangeMapNotification was reported in logs and errors in place of KV ops — this has been fixed, and SET/Upsert is now correctly reported.

NCBC-3721: Fixed a regression in 3.5.0 which would not allow building a Cluster with LoggingMeter disabled.

NCBC-3724: Fixed a known issue with Snappier implementation in the SDK preventing bootstrap .NET with SDK v3.4.10 onwards against server v7.6.0.

NCBC-3725: Fixed a bug where ConfigPushHandler wasn’t performing well under massive config push spam.

NCBC-3727: When Faster Failover with ClustermapChangeNotification is enabled, config polling was short circuited, causing the SDK to rebootstrap because it thinks that it cannot connect to the cluster with the current nodes list. This behavior has been fixed.

NCBC-3732: Fixed logic bug that was causing the ConfigPushHandler to skip all new clustermap config revision.

NCBC-3734: The NRE was causing config revisions to be skipped which meant retries for NotMyVBucket were happening multiple times using the same config revision.

NCBC-3737: KvNotMyBucket retried with old config.

NCBC-3742: Reduced push config spam in ConfigPushHandler.

NCBC-3747: When CB Server 7.2 sends a cluster map changed notification, it is sent with a JSON body containing the new map. After deserializing, we were not replacing $HOST with the correct values, causing the in-memory map to become corrupt and subsequent operations to timeout. This has been fixed, and now after deserializing a pushed notification with a cluster map the SDK replaces $HOST with the endpoint, and applies any overridden network resolution settings. This matches the behavior when we receive a BucketConfig back from an explicit request.

NCBC-3752: Fixed a race condition affecting KeyMapper being updated out of sync with CurrentConfig.

NCBC-3753: The SDK will now only publish a config if it’s a higher revision than the current one.

NCBC-3749: Log the ConfigVersion used by an operation throughout the SDK.

NCBC-3723: Fixed a NullReferenceException in ConfigPushHandler, which meant the code could jump to the error handling and log/exit instead of processing the config.

NCBC-3740: When Faster Failover is available, a GetClusterMap request is no longer the only response to NotMyVBucket.

NCBC-3722: Fixed an IndexOutOfBounds error processing cluster map during ConfigUpdateAsync.

NCBC-3719: There is a bug in the server, and an Unlock operation with an invalid Cas returns Locked instead of CasMismatch status. The SDK now handles this as a CasMismatch.

NCBC-3739: A GetConfigMap begin sent is generally a high priority because it indicates server configuration is outdated due to failover or rebalance. Added a method (which currently only applies to the default ChannelConnectionPool) which allows an operation to be jumped to the front of the line to be sent. It randomly selects the connection from the pool to provide distribution rather than relying on the queue to distribute.

NCBC-3744: Moved ConfigPushHandler from ClusterNode to CouchbaseBucket.

NCBC-3748: Tracking basic metrics for ClusterMapChangeNotification.

NCBC-3751: Every Scope and Collection fetch was being logged in DEBUG mode, adding spam to the logs and roughly doubling the log size. We have now hanged logging there, and also for when waiting for polling, to TRACE. for a config.

NCBC-2901: Fixed the percentiles printed by LoggingMeter to comply with the RFC.

NCBC-3058: Eliminated the App.Metrics dependency and implemented a better approach for tracking logging meter histograms.

NCBC-3314: Renamed SubdocExceptionException to SubdocException.

NCBC-3336: Made it possible to get a collection_id from a QueryIndex object. Fixed the creation of named primary indexes. Added a conditional field to QueryIndex.

NCBC-3564: No error is thrown if the cluster or the bucket authorization fails.

NCBC-3604: Removed Term field from TermRangeQuery.

NCBC-3612: Added an exception handling when calling ContentAs on an Exist spec.

NCBC-3624: When the vector search query options have a value of k < 1, .NET throws a CouchbaseException instead of the expected InvalidArgumentException.

NCBC-3633: SubdocMutation Replace/Remove uses OpCode.Set and OpCode.Delete when an empty path is passed.

NCBC-3635: Added a ReadOnlyCollection<Exception> public backing field to contain the inner exceptions of the AggregateException field.

NCBC-3637: Updated AsyncStreamState to handle all responses enumerated in the RFC for RangeScan.

NCBC-3645: Fixed error thrown against maximum allowed path length.

NCBC-3646: LookupInAnyReplica and LookupInAllReplicas now throw a FeatureNotAvailable error on servers that do not support subdoc.ReplicaRead.

NCBC-3649: Index now updates directly into the response body to prevent unnecessary heap application or memory copy.

NCBC-3657: LookupInSpec.Get() now returns GetFull when the given path is empty.

NCBC-3661: Ensures that a node with the management service is selected so that NullReferenceException is not thrown.

NCBC-3664: Set the expiry of GetResult to DateTime.MaxValue when the secondsUntilExpiry returned spec is 0.

NCBC-3666: Added a backing field for Key in OperationBase. Added a byte[] EncodedKey field to automatically encode and check the size of the Key when creating an operation.

NCBC-3676: Enumeration now uses the RetryHandler to read ahead. It then caches the results and enumerates them first if they are successful.

NCBC-3679: Fixed a bug in QueryErrorContext where the DebuggerDisplay message had an invalid value of :ns instead of ,ns.

NCBC-3686: Throws an exception before sending the request if no vectors are provided.

NCBC-3696: Fixed a bug in SearchIndexManager for scoped indexes.

NCBC-3701: Added missing API overloads to comply with the RFC.

NCBC-3705: Fixed spelling error in ClusterOptions code comments.

NCBC-3709: Updated KV operation metrics to post a single duration for each operation, instead of one duration for each individual retry. The operation count no longer includes retries.

NCBC-3673: If the server does not support vector search or ScopedSearchIndexes, a FeatureNotAvailable error is thrown.

NCBC-3620: Removed unused imports and unnecessary full qualified namespaces. Moved local functions under the return keyword. Made constants private. Updated local functions from camel case to pascal case.

NCBC-3617: Added protostellar support for a new scheme for connecting to the gateway.

NCBC-3667: If the SDK receives a retry-now response, it retries the operation.

NCBC-3671: If the server cannot find the given index, it throws an IndexNotFoundException error.

NCBC-3648: Improved the memory handling of large operation responses.

NCBC-3554: Added retry handling to protostellar.

NCBC-3597: Removed Couchbase.Stellar and Couchbase.NetClient from Couchbase.csproj.

NCBC-3601: Added toggling between a StellarCluster creation and a regular Cluster creation based on the schema detected when Cluster.ConnectAsync is called.

NCBC-3602: Fixed a bug where an error is thrown if a CAS of zero is sent to CNG or protostellar.

NCBC-3655: Added StellarQueryClient so that failed queries can be retried.

NCBC-3670: Removed InvalidArgument fail-fast for LookupinAnyReplica.

NCBC-3672: Fixed failing vector search tests.

NCBC-3716: If you are using Capella or Server versions 7.6.0+, we strongly encourage you to upgrade to SDK v3.5.1+. While this version will continue be compatible and supported with server 7.6 (and newer instances of Capella, using 7.6), you may encounter timeout exceptions during rebalances under KV high workload.

NCBC-3599: The initial parameter of Increment and Decrement operations is now unset by default. This means the SDK will throw a DocumentNotFoundException upon calling Increment or Decrement with a non-existing key without providing an initial value.

await collection.Binary.IncrementAsync("thisKeyDoesNotExist").ConfigureAwait(false); → Now throws DocumentNotFoundException

await collection.Binary.IncrementAsync("thisKeyDoesNotExist", options ⇒ options.Initial(0)).ConfigureAwait(false); → Creates the document with counter at 0

NCBC-3599: Fixed SDK bugs related to Nullability of Increment, Decrement, and related options.

NCBC-3565: Added error handling for "index does not exist" query error.

NCBC-3579: Support DocumentNotLocked exception when collection.Unlock() is called on a document that is not locked.

NCBC-3606: Added SDK Support for Scoped Search Indexes.

NCBC-3596: Support added for maxTTL value of -1, for collection "no expiry".

NCBC-3716: If you are using Capella or Server versions 7.6.0+, we strongly encourage you to upgrade to SDK v3.5.1+. While this version will continue be compatible and supported with server 7.6 (and newer instances of Capella, using 7.6), you may encounter timeout exceptions during rebalances under KV high workload.

NCBC-3434: A regression introduced in a recent release prevented WaitUntilReady from pinging nodes — this has been fixed, and WaitUntilReady now correctly detects state.

NCBC-3503: There was a possibility of ClusterVersionProvider.GetVersionAsync failing, if nodes have no ManagementUri, owing to randomized node order. This has been fixed, and GetRandomManagementUri() should never now throw NullReferenceException.

NCBC-3530: Made the ConnectionString class now accept couchbase2 schema.

NCBC-3532: Added AsReadOnly record to Index APIs options.

NCBC-3538: Improved recovery time in Config Push to 300ms.

NCBC-3541: Added AsReadOnly record to Bucket Management APIs options.

NCBC-3551: Added AsReadOnly record to Collection Management APIs options.

NCBC-3568: Added AsReadOnly Record to GetAllScopesOptions.

NCBC-3516: Made fallback usage of DefaultSerializer trimmable.

NCBC-3518: Removed internal transcoder dependencies on DefaultSerializer.

NCBC-3716: If you are using Capella or Server versions 7.6.0+, we strongly encourage you to upgrade to SDK v3.5.1+. While this version will continue be compatible and supported with server 7.6 (and newer instances of Capella, using 7.6), you may encounter timeout exceptions during rebalances under KV high workload.

NCBC-3397: IOperation.Elapsed was not correctly counting duration between retries — the stopwatch field of IOperation/OperationBase is stopped in HandleOperationCompleted() and never re-started. This has now been fixed, and the Elapsed field of OperationBase now correctly increments with the stopwatch time after each retry cycle.

NCBC-3498: Added code documentation to PersistentList as the internals use reference comparisons, but there is no guarantee that internally the document might be reloaded by the database. The documention instructs users to override the Object.Equals method on their POCOs so that that values of the objects will be compared and not the objects' reference.

NCBC-3510: Fixed a regression in Config Push Notification / Faster Failover performance. Config Push notifications are now handled by a single thread per node in a LIFO manner, and skip out of date push notifications, as well as providing more logging around config updates to help troubleshoot in the future. Additionally, GetClusterConfig asks for the old version, not the pushed version.

NCBC-3526: The Search Service’s NumericRangeQuery’s `MaxInclusive property was defaulting to false. It now defaults to true, in line with the rfc.

NCBC-3543: DefaultSerializer will now correctly handle Unicode surrogate pairs on buffer boundaries.

NCBC-3472: Support added to bucket settings for change history feature.

NCBC-3502, NCBC-3506: Merging couchbase-net-stellar into couchbase-net-client, for upcoming Cloud Native Gateway support.

NCBC-3481: The legacy Enum.GetValues(Type) overload is not AOT-compatible. Added conditional compilation to use the Enum.GetValues<TEnum>() overload on .NET 6 and later.

NCBC-3487: Reduced reliance on SerializeWithFallback, which is incompatible with trimming and NativeAOT.

NCBC-3488: Delaying creation of CollectionQueryIndexManager, which will allow it to be left off the DI container, and trimmed out of the output executable if unused.

NCBC-3489: Implemented an in-flight operation limit to provide backpressure. The previous design allowed a single connection from the connection pool to collect a large number of in-flight operations, rather than ensuring a more even spread of operations across connections in the pool. This potentially allowed small operation may be blocked waiting for large operation to pass over the network socket. A more even spread of operations doesn’t guarantee this will be the case, but does make it more likely.

NCBC-3508: Support HTTP response streaming in legacy .NET runtimes

NCBC-3539: System.Text.Json is now used to deserialize document expiry — for improved performance and compatiblity with trimming and NativeAOT.

NCBC-3545: Fixes a regression introduced in 3.4.12 where a ClusterNode might be disposed and then reused, which causes an exception to be raised. This issue is raised if the cluster is configured to use Alternate Addressing, but not DNS-SRV.

NCBC-3716: If you are using Capella or Server versions 7.6.0+, we strongly encourage you to upgrade to SDK v3.5.1+. While this version will continue be compatible and supported with server 7.6 (and newer instances of Capella, using 7.6), you may encounter timeout exceptions during rebalances under KV high workload.

NCBC-3490: When a request includes a CAS, MutateIn should now throw a CasMismatch exception if the status is KeyExists. Otherwise, for KeyExists, it will continue to throw DocumentExistsException.

NCBC-3493: When a Private Link is enabled, the SDK was not properly using the provided config and all of the VBuckets were mapped to the same node. This could cause a recurring KvNotMyVBucket, which would eventually become an AmbiguousTimeoutException thrown to the user. This behavior has now been fixed — changes have been made so that NetworkResolution is propagated to BucketConfig, duplicate nodes not added to nodes list, and entries in LookupDictionary are only made for nodes with actual ports.

NCBC-3496: WaitUntilReady should now use the cluster map and not the ServiceType enum by default — removing spurious error messages about services which are not being used.

NCBC-3455: During a MultiLookup, the SDK should now correctly throw DocumentUnretrievableException in LookupInAnyReplica, for key not found.

NCBC-3465: Exist specs in LookupInResults was not returning ContentAs — it now returns bool Exist value serialized as T when calling LookupinResult.ContentAs<T>(), as per RFC.

NCBC-3473: GetInAnyReplica could fail when it should have been successful, throwing DocumentUnretrievable — it should now return the first successful operation (unless all fail).

NCBC-3484, NCBC-3485, NCBC-3486: Several bugs in LookupInAny and LookupInAllReplicas have been fixed.

NCBC-3494: Added a client-side check for TooManySpecs in LookupIn.

NCBC-3387: Removed internal keword from ICollectionQueryIndexManager, facilitatiing better testing.

NCBC-3479: Added trimming and AOT annotations to Analytics and Search clients.

NCBC-3492: When an EConfigOnly (0xd) response is received, the SDK assumes that this may mean a stale config, and so fetches a new config and publishes it for processing.

NCBC-3495: Moved LookupInAllReplicasAsync and LookupInAnyReplicaAsync into ICouchbaseCollection.

NCBC-3497: Added additional DEBUG logging ConnectionFactory.CreateAndConnectAsync, to aid TLS troubleshooting.

NCBC-3716: If you are using Capella or Server versions 7.6.0+, we strongly encourage you to upgrade to SDK v3.5.1+. While this version will continue be compatible and supported with server 7.6 (and newer instances of Capella, using 7.6), you may encounter timeout exceptions during rebalances under KV high workload.

NCBC-3446: When passed as readonly(true), Readonly Query was accepting UPDATE query and was updating the document in collection, when it should have failed. This should no longer occur.

NCBC-3448: IndexNotFoundException was not raised when QueryIndexManager.watchIndex was called with a non-existent index — this has been fixed, and the correct exception should now be thrown.

NCBC-3460: Fixed a bug where a null reference exception was sometimes occurring when bootstrapping a Memcached bucket.

NCBC-3467: Fixed a regression in lambda-based sub doc API, due to LookupInResult changes.

NCBC-3449: The SDK was throwing a NullReferenceException for the ITypeSerializer when setting a Transcoder in the Options due to erroneous logic in CouchbaseCollection. Transcoders are now used for deserialization, and RawBinary/RawString Transcoders now initialise the DefaultSerializer when instantiated (like for JsonTranscoder) which, along with changed logic in CouchbaseCollection when returning LookupInResults, means that this no longer occurs.

NCBC-3466: Improvements for internal testing.

NCBC-3482: Faster Failover/Push config is now ensabled by default.

NCBC-3130: For improved performance and trimmability, OrphanReporter has been rewritten to serialize POCOs using a JsonSerializerContext rather than using LINQ objects from Newtonsoft.

NCBC-3402: Improved trimming support for internal DI.

NCBC-3404: Replaced Newtonsoft.Json with System.Text.Json, using source generated JsonSerializerContext, for Eventing management. This is now compatible with trimming and AOT compilation, and should also provide performance benefits. Use System.Text.Json for Eventing Management

NCBC-3405: Added trimming annotations to LoggingMeter.

NCBC-3420: The DefaultSerializer was used to deserialize query plans — for consistency, this now uses System.Text.Json.

NCBC-3453: Reduced the default value for the IdleHttpConnectionTimeout client setting to 1 second. The previous default (4.5 seconds) was too close to the 5-second server-side timeout, and could lead to spurious request failures.

NCBC-3471: Microsoft DI Extensions (Couchbase.Extensions.DependencyInjection) are now more compatible with trimming and AOT compilation. The changes also help application start up speed in non-AOT cases.

NCBC-3424: Future server versions will add an extra item to the features list returned, which effects the parsing of the body. This change prepares for the effects of those flexible framing extras.

NCBC-3445: At some point, SubDocMultiPathFailureDeleted was added as a special case of SubDocMultiPathFailure, but from an SDK point of view they should be handled them similarly. This change ensures that when doing a LookupIn against a Tombstone with AccessDeleted flag set, SubDocMultiPathFailureDeleted response status should not throw, and should be treated the same as SubDocMultiPathFailure.

NCBC-3423: Added GetClusterConfigWithKnownVersion support to Hello.

NCBC-3425: Added a HELLO flag called DedupeNotMyVbucketClustermap.

NCBC-3427: Added SnappyEverywhere flag support, in preparation for the .NET SDK supporting Compression.

NCBC-3428: Added ClustermapChangeNotificationBrief flag support to subscribe to configuration notifications, where available.

NCBC-3429: Added support for Duplex mode flag to Hello, for Unordered Execution.

NCBC-3430: Added ClustermapChangeNotification flag support.

NCBC-3421: Deserializing K/V operations with the DefaultSerializer was allocating an excessive number of buffers for each operation. This change introduces a reusable pool of text readers which reads directly from the memory buffer without stream-related overhead or intermediate buffers. This results in a performance gain and a significant reduction in heap allocations when deserializing from a memory buffer.

NCBC-3432: Added additional logging at the IO level to capture more details of exceptions thrown when sockets are opened.

NCBC-3438: Several of the listed dependencies for the .NET 6 target were unnecessary, as those packages are now included in the .NET framework and we’re not targeting a higher version. We have removed these NuGet dependencies for the .NET 6 Target, which will reduce restore time and size for consumers.

NCBC-3367: The SDK was returning QueryIndexes with null values for Bucket/Scope/Collection names (BucketName should return the Keyspace value when null). Added BucketName field with backing field for conditionally returning either BucketNameField or Keyspace.

NCBC-3417: MutateIn was modifying global Transcoder setting; nothing registered as a Singleton should be mutable and changes have been made to ensure that this can no longer happen.

NCBC-3433: Fixed regression in 3.4.8 which could cause IOException if Query has no content.

NCBC-3412: Support Query with Read from Replica

NCBC-3418: Experimental support for HTTP2 when using the Query service

NCBC-3351: SDKs must encode URIs

NCBC-3437: Add .NET 4.8 back to .NET SDK unit and integration tests

NCBC-3384: Resolve all compiler warnings

NCBC-3386: Add conditional support for TLS 1.3 for .NET 6.0 and higher

NCBC-3401: Scan: Implement latest RFC revision (#9)

NCBC-3403: Improve memory usage of SearchClient

NCBC-3392: Scan: RangeScanCreate operation did not receive the MutationTokens from the ScanOptions, as ConsistentWit was not sent in RangeScanCreate packets. This has been remedied, and MutationState tokens are now sent in RangeScanCreate packets.

NCBC-3395: Scan: Sampling Scan Limit parameter must be < 0. An InvalidArgumentException is now thrown when creating a SamplingScan with Limit < 0.

NCBC-3399: Fixed edge case in bootstrapping around NRE in PruneNodes.

NCBC-3391: Scan: Implemented PrefixScan helper method.

NCBC-3350: NotMyVBucket will no longer result in TaskCancellationException.

NCBC-3376: Correct timeout response will now be returned during a rebalance.

NCBC-3379: OpenTelemetry tracing was losing track of the parent span in cases where the parent span was not sampled, resulting in orphaned spans and increased trace volume. By capturing the ExecutionContext, if any, when queuing operations on the ChannelConnectionPool, and sending the operations on the captured context, the spans are now correctly sampled.

NCBC-3380: When IOperation.ExtractBody is called it should always dispose of the returned IMemoryOwner, generally with a using statement; . Failure to do so will cause the buffer to be garbage collected rather than returned to the ArrayPool — which can lead to memory holes and decreased GC efficiency. This has no been fixed, and should no longer occur.

NCBC-3382: Streaming support now working correctly for Analytics, Query, and Views.

NCBC-3383: Couchbase.ServiceNotAvailableException: Service n1ql is either not configured or cannot be reached.

NCBC-3390: Get Cluster Map operations were linked to the bootstrap trace, cusing erroneous large traces. A check has been added which fixes this.

NCBC-3392: Scan: Use ConsistentWith MutationTokens for RangeScanCreate Operation.

NCBC-3393: Fixed regression where OperationCanceledException continues after rebalance completes.

NCBC-3391: Scan: Implemented PrefixScan helper method.

NCBC-2394: Query 4040 is now handled like 4050, et al — e.g. prepared statement cache for it is removed and transparent reprepare is performed.

NCBC-3354: Changed logging to use LoggerMessage in Channel classes. Added ChannelConnectionEvent in LoggingEvents.

NCBC-3378: Improve GET_CID use in CouchbaseBucket.

NCBC-3381: Removed ClusterNodesChanged and VBucketMapChanged (which are only used internally) from BucketConfig.

NCBC-3300: SamplingScan: Fixed bug in limiting option

NCBC-3301: SamplingScan: Fixed bug where requesting too few documents returned incorrect responses.

NCBC-3345: In the latest development server versions, 0xD is occasionally returned by the server.

NCBC-3273: Added SDK Support for Native KV Range Scans.

NCBC-3364: Improved hot-path performance in ClusterContext.GetOrCreateBucketAsync.

NCBC-3334: KvNotMyVBucket errors after add node + rebalance.

NCBC-3337: NullReferenceException when bootstrapping against a non-existent bucket.

NCBC-3347: IGetResult shouldn’t have an internal Status property.

NCBC-3360: Fix QueryContext bug in QueryIndexManager.

NCBC-3362: SDK writes to _default collection when intended collection is dropped.

NCBC-3363: SubDoc SuccessDeleted not treated as Success.

NCBC-3365: Change Search Metadata setters from internal to public.

NCBC-3369: Ensure ClusterNode list matches Cluster config after rebalance up/down.

NCBC-3372: Removed/rebalanced out node continues to be hit with http requests.

NCBC-3220: Properly map server query timeout while streaming (1080).

NCBC-3308: Scan: Refactor sorting/merging into non-blocking implementation.

NCBC-3332: Protostellar: Implement KV SubDoc.

NCBC-3355: Update FIT performer.

NCBC-3274: Add public API for KV Range Scan.

NCBC-3370: Lock on sync object instead of nodes list.

NCBC-3340: When an op timed out, the socket connection was closed and then recreated. With a large number of unexpected timeouts, many sockets could be left in TIME_WAIT. Making ChannelConnectionProcessor reuse connections after timeout should reduce the number of file descripters and local ports left open.

NCBC-3356: Cluster level query_context, which is not supported by Server versions earlier than 7.0, has been removed for these versions.

NCBC-3343: Fixed a bug where SelectBucket may not be called on the internal node used as the bootstrapping endpoint. This resulted in a BucketNotConnected error for certain ops — which will now no longer occur.

NCBC-3309: Handled query_context changes by adding to every index manager request.

NCBC-3348: When ConnectionString hosts are null, the SDK now throws an exception, with a more explicit error message.

NCBC-3353: Removed build targets for out-of-support versions of .NET Framework.

NCBC-3316: Scan: Refactored operation parsing, so RangeScanContinue.OnNext() doesn’t get called after the first batch of a partition has been consumed.

NCBC-3329: NamedBucketProxyGenerator and NamedCollectionProxyGenerator caches were not thread-safe during start up. This applies primarily to unit testing scenarios — most MVC applications were not affected, as it doesn’t affect anything once the DI container is configured, because startup DI registration is single-threaded.
