GOCBC-1680: Improved retry handling for http operations.

GOCBC-1632: Added support for zone-aware replica reads, at API stability level uncommitted.

GOCBC-1657: Updated tracing when using the couchbase2 scheme, to send traces to the server over gRPC.

GOCBC-1655: Fixed the error messages for some connection string parameter parsing errors, where the message was not referring to the correct parameter.

GOCBC-1660: Fixed a possible data race that occurred because the value of a lock was being logged at debug-level.

GOCBC-1640: Adjusted logging levels when logging about receiving cluster configs older than the SDK already has.

GOCBC-1625: Fixed issue where a data race could occur when requests were retried concurrently with being cancelled.

GOCBC-1643: Fixed issue where couchbase2 mode did not wait for operations to complete on close.

GOCBC-1626: Addressed an issue where performing operations after calling cluster.Close (or calling close twice) would lead to a panic. On close the SDK will now cancel all in flight operations and block waiting for them to complete/be cancelled. All operations will now fast fail if called after close.

GOCBC-1631: Added handling to treat memcached scope not found errors the same as collection not found errors.

GOCBC-1608: Return ErrFeatureNotAvailable if requested search capabilities aren’t available.

GOCBC-1614: Updated SDK API volatility levels:

GOCBC-1582: Fixed issue where math.MaxUint32 was causing an error when used with fmt.Errorf.

GOCBC-1482: Fixed issue where there was inconsistency in whether Couchbase error types were returned as pointers across services, now all Couchbase errors are returned as pointers. Improved the string output for TimeoutError. We expect this to have a minimal impact but may impact some users who are using errors.As or directly type asserting errors.

GOCBC-1575: Improved the interface for BucketSetting HistoryRetentionCollectionDefault field to use a constant value rather than a bool pointer.

GOCBC-1470: Added a V2 Collection management API, accessed via Bucket.CollectionsV2(), which has improved method signatures for CreateCollection, UpdateCollection, and DropCollection.

GOCBC-1454: Added support for JSON marshalling/unmarshalling of search indexes.

GOCBC-1457: Reduced the default timeout for idle HTTP connections 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

GOCBC-1459: Added support for history retention settings to bucket and collections managers, at API stability uncommitted.

GOCBC-1461: Updated ExistsSpec response to handle ContentAt better:

GOCBC-1540: Added support for ErrDocumentTooDeep which is only used in couchbase2 mode, equivalent to ErrPathTooDeep.

GOCBC-1393: Updated behaviour for when queries are retried when enhanced prepared statements are used (i.e. prepared statements against server version >= 6.5.0). When an error is translated to a QueryPreparedStatementFailureRetryReason it will invalidate the prepared statement cache entry and attempt to reprepare the statement.

GOCBC-1395: Improved timeout error handling for http based services - if we know that an operation has already timed out then we will now immediately return a timeout error. Retry reason context is now carried throughout the lifetime of an entire prepared statement request.

GOCBC-1322: Added volatile support for kv range scan.

GOCBC-913: Ensure that only available services are used for Ping if no services specified.

GOCBC-923: Updated const declarations to add types to improve API reference.

GOCBC-879, GOCBC-890: Fixed issue causing Cluster level operations to return errors when performed before underlying cluster or bucket connections are ready. These operations (query, search, analytics, views, management APIs) will now behave like key value operations - waiting for connections to be ready before they are sent. The WaitUntilReady call can still be used for verifying that connections are ready.

GOCBC-891: Fixed issue where the Name property of a Role was being sent as the incorrect json field name.

GOCBC-897: Fixed issue where operations with incredible short timeouts (timing out before operation sent) could cause a data race.

GOCBC-882: Fixed issue where an invalid cluster config would trigger a shutdown of the underlying core SDK causing operations to fail.

GOCBC-884: Fixed issue where UpsertUser sent an invalid request if a role was specified with no bucket.

GOCBC-879, GOCBC-890: Performing Cluster level operations (query, search, management APIs) before underlying cluster or bucket connections are ready causes errors to be returned. To mitigate this the err := WaitUntilReady(time.Duration, WaitUntilReadyOptions) operation can be used on either Cluster or Bucket which will either:

GOCBC-843: Updated to the new version of gocbcore. This change includes a key behavioral change of no longer reporting non-configuration related connect time errors.

GOCBC-845: Add support for the WaitForReady operation, support waiting for the KeyValue service to be ready.

GOCBC-831: Fixed issue where search consistency options were not being set in the request payload.

GOCBC-662: The server requires that any subdoc xattr ops are at the beginning of the ops list. If the user provides an ops list containing subdoc xattr ops out of order, the SDK will now reorder it for them and then reorder it back again when it gets the result. This ensures that ContentAt works as expected.

GOCBC-700: Made improvements to errors returned from management operations. They now provide more contextual information.

GOCBC-716: SDK now returns a FlushNotEnabled error if bucket flush not enabled.

GOCBC-728: Added cluster level Ping operation.

GOCBC-807: Updated best effort retry strategy to use an exponential backoff calculator.

GOCBC-820: Removed context.Context from search index manager operations. Note that whilst this is a breaking change it was deemed best to break it and make sure any users who are using it know that they are using unused functionality.

GOCBC-814: Fixed issue where search was looking for incorrect field in the JSON response.

GOCBC-817: Fixed issue where opening a bucket with the same name twice led to incorrect behaviour on both buckets.

GOCBC-805: Updated timeout behavior across the SDK to be consistent. If an operation level timeout is provided then it is used, otherwise the respective global timeout is used.

GOCBC-804: Fixed issue with timeouts not being respected for HTTP requests, leading to them never timing out.

GOCBC-775: Improve error message for when performing cluster level operations with no connections available.

GOCBC-776: Added support for KVDurableTimeout.
