TiDB

TiDB v7.5.8 — released on September 17, 2026

TiDB v7.5.8 adds a store label to the pd_cluster_status metric, making it easier to identify affected TiKV stores and aggregate cluster-wide PD status. The maintenance release also fixes several operational issues, including excessive CPU consumption during query planning, a potential asynchronous statistics-loading panic for newly added indexes, and a race that could crash TiDB while cleaning up a UNION query.

TiProxy v1.3.3 — released on September 16, 2026

TiProxy v1.3.3 adds more flexible load-balancing controls, including configurable balance factors, routing policies, migration speed, and CPU-based balancing. It also improves failover and memory management, with new protections and metrics for better reliability and observability.

TiUP v1.17.1 — released on September 8, 2026

TiUP v1.17.1 corrects Grafana datasource replacement when VictoriaMetrics is used, collects node_exporter metrics from dedicated TiDB Dashboard hosts, and preserves shared exporter directories and systemd units when a cluster is destroyed with ignore_exporter: true. It also prevents concurrent TLS certificate distribution from copying an empty CA certificate and blocking component startup.

TiDB Cloud

Automate Starter and persistent agent workspaces with ti

Available on: TiDB Cloud Starter

Status: Public preview for TiDB Cloud CLI (ti)

TiDB Cloud CLI (ti) is a new automation-oriented command-line interface for managing TiDB Cloud Starter instances and file systems in TiDB Cloud Filesystem. Scripts, CI jobs, and AI agents can create and manage Starter instances, run SQL statements, and create or access persistent file-system workspaces through file commands and supported mounts.

The CLI returns JSON by default and supports JMESPath queries, while applicable operations offer --wait and --dry-run. TiDB Cloud Filesystem provides a persistent, shareable namespace that remains available independently of the local machine, sandbox, or CI runner accessing it.

Manage Premium changefeeds programmatically

Available on: TiDB Cloud Premium

New changefeed API endpoints let applications create, list, inspect, delete, pause, resume, and scale TiDB Cloud Premium changefeeds. The API supports real-time replication to downstream systems including Apache Kafka, MySQL, Amazon S3, and Alibaba Cloud OSS, making CDC workflows easier to integrate with deployment and operations automation.

Release notes

Connect through IPv6 and cross-region AWS PrivateLink

Available on: TiDB Cloud Dedicated (on AWS)

Availability: Upon request

TiDB Cloud Dedicated now supports inbound IPv6 connectivity over AWS PrivateLink. After TiDB Cloud Support enables the feature, you can switch a TiDB node group to dual-stack and create a dual-stack AWS interface endpoint, while IPv4 connectivity remains available.

You can also create an AWS interface endpoint in one region and privately connect it to a TiDB Cloud Dedicated cluster in another region using the same connection string. A cross-region PrivateLink service fee applies for each added region. Removing a region does not affect existing connections.

Detect bursts of slow SQL statements

Available on: TiDB Cloud Premium

TiDB Cloud Premium adds three built-in alert rules that notify you when more than 20 SQL statements exceed a latency threshold of 256 ms, 512 ms, or 4096 ms within one minute. The rules help identify periods when unusually large numbers of SQL statements are running slowly, rather than focusing only on a single slow statement.

Filter Premium audit logs and review operational events

Available on: TiDB Cloud Premium

TiDB Cloud Premium now supports audit filter rules based on SQL user, event class, table, and execution status, helping organizations capture the database activities relevant to their security and compliance requirements. If no filter rules are configured, no audit events are written.

The Events page is also available for Premium instances. It records event type, status, message, trigger time, and trigger user, with event data retained for seven days.

Quick updates

TiDB Cloud

• Essential and Premium — You can temporarily authorize TiDB Cloud Support to access Plan Replayer files for SQL performance troubleshooting, choose the access duration, extend it, or revoke access. The files can contain SQL text, schemas, optimizer statistics, and other potentially sensitive metadata, but not table-row data. Learn more · Release notes
• Essential — Billing for backup usage and network egress began taking effect gradually on September 1. Network egress is billed separately instead of being included in RCU charges. Billing overview · Release notes
• Essential — Instances that include the enhancements announced on June 30 now display CLOUD.202603.x as their TiDB version on the instance overview page. Release notes
