• Smart-client-handoffs is now enabled by default on Redis Enterprise and AMR; see #​3248
• Some logging events incorrectly used duplicated ids - resolved; see #​3266

All Changes

What's Changed

• Distinguish explicit and inferred TLS host names useful when cluster shards exposed using TLS/SNI by @​sandeepkunusoth in #​3250

New Contributors

• @​sandeepkunusoth made their first contribution in #​3250

• When SslHost is specified, it is always used for SNI
• Otherwise, for endpoints discovered at runtime:
  • If they are advertised with a host name, that host name is used for SNI
  • Otherwise the declared host name in the configuration is used

(previously, the declared host name in configuration would take precedence over an advertised host name if SslHost was not specified)

v3.3.0

Features

The primary feature in 3.3.0 is "smart-client-handoffs" (aka "hitless"), whereby the client responds to server maintenance notifications on suitable environments. This feature is currently opt-in, and is planned to be automatic (opt-out) in most supported cases in an upcoming release.

Documentation

Opt in through configuration;

my-redis.internal.example.com:6379,maintNotifications=Auto

or in code:

options.MaintenanceNotifications = MaintenanceNotificationMode.Auto;

Changes

• Server-native maintenance notifications: opt in, react, hand off, and recover when nothing is announced by @​mgravell in #​3191

Maintenance

• Sort the public API tracking files, with a script that keeps them that way by @​mgravell in #​3245
• Promote geo-redundant failover and the Redis 8.10 bindings out of preview by @​mgravell in #​3247
• Retire SER001: vector sets are not experimental any more by @​mgravell in #​3246

v3.1.0

Compare Source

What's Changed

• 3.1 - Client-side geographic failover by @​mgravell in #​3025

This is a major feature, with extensive documentation.

Note that it currently has an [Experimental] marker, linking here, but: this is purely for an abundance of caution; it is considered released and fully supported.

(engineering)

• CI: stop dpkg starting redis-server (Windows/WSL install hang on 8.10) by @​mgravell in #​3145
• Make the previous "we will remove this in 3.0" features errors rather than warnings, and reframe as "...in 3.2"

available on NuGet

Risk Analysis 🛡️ · Low Risk

✅ Approved — Low-Risk Change

Details

Renovate minor version bump of StackExchange.Redis (3.0.25 → 3.1.0), a single-line edit in Directory.Packages.props. No source, test, config, infra, or opted-out files are touched, so there is no runtime code-path change to review. The 3.1.0 release adds an opt-in, experimental geo-failover feature and defers (does not remove) previously-deprecated APIs to 3.2, so no breaking change is in effect here.
