Redis 8.6 Support

Added support for Redis 8.6, including new commands and features for streams idempotent production and HOTKEYS.

Smart Client Handoff (Maintenance Notifications) for Cluster

note: Pending RS version release

This release introduces comprehensive support for Redis Enterprise Cluster maintenance notifications via SMIGRATING/SMIGRATED push notifications. The client now automatically handles slot migrations by:

• Relaxing timeouts during migration (SMIGRATING) to prevent false failures
• Triggering lazy cluster state reloads upon completion (SMIGRATED)
• Enabling seamless operations during Redis Enterprise maintenance windows

(#​3643) by @​ndyakov

OpenTelemetry Native Metrics Support

Added comprehensive OpenTelemetry metrics support following the OpenTelemetry Database Client Semantic Conventions. The implementation uses a Bridge Pattern to keep the core library dependency-free while providing optional metrics instrumentation through the new extra/redisotel-native package.

Metric groups include:

• Command metrics: Operation duration with retry tracking
• Connection basic: Connection count and creation time
• Resiliency: Errors, handoffs, timeout relaxation
• Connection advanced: Wait time and use time
• Pubsub metrics: Published and received messages
• Stream metrics: Processing duration and maintenance notifications

v2.5.0: MongoDB Go Driver 2.5.0

Compare Source

The MongoDB Go Driver Team is pleased to release version 2.5.0 of the official MongoDB Go Driver.

Release Highlights

This release adds a preview of CRUD support for prefix/suffix/substring indexes. Prefix, suffix and substring search are in preview and should be used for experimental workloads only. These features are unstable and their security is not guaranteed until released as Generally Available (GA). The GA version of these features may not be backwards compatible with the preview version.

Also, this release adds AsFloat64(), AsFloat64OK() to bson.RawValue, and DefaultDocumentMap() to bson.Decoder in the BSON package.

Additionally, this release adds ErrorCodes() to parse server error codes from an arbitrary Go error, and exposes atClusterTime in snapshot sessions.

Moreover, this release fixes several bugs, including potential heap out-of-bounds read in GSSAPI error handling.
