-# Percona Monitoring and Management 3.5.0
-
-**Release date**: 20 November 2025
-
-Percona Monitoring and Management (PMM) is an open source database monitoring, management, and observability solution for MySQL, PostgreSQL, MongoDB, Valkey and Redis. PMM empowers you to:
-
-- monitor the health and performance of your database systems
-- identify patterns and trends in database behavior
-- diagnose and resolve issues faster with actionable insights
-- manage databases across on-premises, cloud, and hybrid environments
-
-## Release summary
-
-This release introduces full Redis and Valkey monitoring, PostgreSQL 18 support, new built-in advisors and alert templates, and major MongoDB dashboard improvements.
-
-It also delivers enhanced TLS flexibility, improved Nomad GC configuration, and multiple performance fixes.
-
-## Release highlights
-
-### Free built-in advisors and alert templates replace Percona Platform
-
-We're making Percona Monitoring and Management (PMM) more powerful and self-sufficient.
-
-As we prepare for the discontinuation of Percona Platform services in March 2026, we've migrated all database advisors, checks, and alert templates directly into PMM. They are now included by default, work completely offline, and require no subscription.
-
-This transition delivers a simpler PMM that runs all checks and alerts locally, without relying on internet access or external dependencies. Here’s what to expect from this change:
-
-- **PMM 3.5.0+:** [Advisors](https://docs.percona.com/percona-monitoring-and-management/3/advisors/advisors.html) and [alert templates](https://docs.percona.com/percona-monitoring-and-management/3/alert/templates_list.html) are now built-in with every installation—completely free, with no subscription required. All advisors (previously across Basic, Standard, and Premium tiers) work seamlessly with no service interruption or changes to your workflow.
-
-- **PMM 3.0.0 - 3.4.x:** Internet-connected PMM instances will continue receiving free advisors and templates from the Platform until its discontinuation in PMM 3.7.0. Once the Platform shuts down, you'll be prompted to upgrade to 3.5.0+ for continued access to advisors and templates.
-
-- **PMM 2.x:** PMM 2 is discontinued and Platform connectivity for advisors and templates will cease after its official End Of Life. To continue using advisors and alert templates, [upgrade using the recommended path](https://docs.percona.com/percona-monitoring-and-management/3/pmm-upgrade/migrating_from_pmm_2.html).
-
-- **Percona Account authentication:** With the Platform's discontinuation, the ability to sign into PMM using Percona Account credentials will no longer be available. [Migrate to a supported authentication method](https://docs.percona.com/percona-monitoring-and-management/3/admin/manage-users/edit_users.md#migrate-from-percona-account-authentication-deprecated) before then to maintain access. PMM supports all authentication methods available in Grafana, including basic auth, LDAP, OAuth and SAML.
-
-### Valkey and Redis monitoring support
-
-PMM now provides native support for monitoring Valkey and Redis databases. Valkey is a high-performance open-source alternative to Redis that maintains full protocol compatibility, enabling PMM to monitor both databases using the same proven infrastructure.
-
-For this, PMM includes ten dedicated Valkey/Redis dashboards that help you monitor performance, detect latency spikes, identify replication issues, and troubleshoot bottlenecks across your deployments:
-
-- [**Overview**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-overview.html): summarizes deployment health and performance.
-- [**Clients**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-clients.html): shows client connections, blocked clients, and buffer usage.
-- [**Cluster Details**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-cluster-details.html): displays cluster topology, node roles, and replication offsets.
-- [**Command Details**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-command-details.html): analyzes command throughput, execution time, and latency patterns so you can optimize queries.
-- [**Load**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-load.html): tracks workload distribution, read/write patterns, and CPU/I/O usage.
-- [**Memory**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-memory.html): monitors memory use, eviction policies, and keyspace metrics.
-- [**Network**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-network.html): shows network bandwidth and traffic patterns.
-- [**Persistence**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-persistence.html): reviews RDB and AOF operations and rewrite performance.
-- [**Replication**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-replication.html): tracks replication lag, synchronization status, and backlog.
-- [**Slowlog**](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-valkey-redis-slowlog.html): identifies slow commands and pinpoints performance bottlenecks. Full Query Analytics (QAN) support for Valkey/Redis is planned for a future release. Use Valkey's built-in SLOWLOG command for detailed query analysis in the meantime.
-
-To get stated, see [Connect Valkey databases to PMM](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/connect-database/valkey.html).
-
-
-
-### PostgreSQL 18 Community support
-
-PMM now supports PostgreSQL 18 Community Edition, with full compatibility for dashboards and Query Analytics. Full support for all PostgreSQL 18 variants and enhanced metrics collection are planned for PMM 3.6.0.
-
-To connect your PostgreSQL 18 database to PMM, see [Connect PostgreSQL databases to PMM](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/connect-database/postgresql.html).
-
-### MongoDB dashboard improvements
-
-We've made several enhancements to improve MongoDB monitoring:
-
-- Renamed **Query Execution Times** panel to **Operation Latencies** in **Router Summary**, **Sharded Cluster Summary**, and **Replica Set Summary** dashboards for clarity
-- Fixed duplicate service counts in MongoDB dashboards and node filtering issues in **Replica Set Summary**, **Cluster Summary**, and **Router Summary** dashboards
-- Added idle connections metric to the **Connections** panel in **Cluster Summary** and **Replica Set Summary** dashboards to help identify performance issues:
-
- 
-
-### Query Analytics shows only your monitored databases
-
-Query Analytics (QAN) now provides a cleaner view by excluding PMM Server's internal PostgreSQL queries from the default display.
-
-This helps you focus on your database performance without the distraction of PMM's operational activity. If you need to monitor PMM Server queries for troubleshooting or High Availability scenarios, re-enable the option in **PMM Configuration > Settings > Advanced Settings**.
-
-For details, see [QAN for PMM Server](https://docs.percona.com/percona-monitoring-and-management/3/use/qan/index.md#qan-for-pmm-servers-internal-postgresql).
-
-
-
-### Support for partial certificates for remote MySQL monitoring
-
-PMM now supports adding remote MySQL instances using partial TLS configurations. You can configure TLS connections using only the CA certificate, without requiring client certificate and key files.
-
-This enables you to:
-
-- monitor Azure MySQL Flexible Server and Google Cloud SQL (MySQL) using only the downloaded CA certificate file.
-
-- simplify TLS setup by connecting with just the CA certificate, no client certificate or key required.
-
-For instructions, see [Connect MySQL databases to PMM](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/connect-database/mysql/mysql.html).
-
-Similar support for PostgreSQL will be available in a future release.
-
-### Improved data privacy: Disable query examples in the UI
-
-You can now enhance data privacy in PMM by disabling the collection and display of sensitive SQL queries when adding MySQL or PostgreSQL services.
-
-The new **Disable query examples** option prevents PMM from showing full SQL queries containing real data in QAN.
-
-When this option is enabled, the **Examples** tab in QAN will not display any query examples, helping protect sensitive information while still providing valuable performance insights.
-
-To enable, go to **PMM Configuration > PMM Inventory > MySQL/PostgreSQL > Add Service > Additional Options** and select **Disable query examples**:
-
-
-
-### Configurable Nomad Garbage Collection
-
-PMM now supports configuring Nomad client-side garbage collection (GC) through environment variables.
-
-You can tune cleanup intervals, disk and inode thresholds, and allocation limits to reduce resource buildup and keep Nomad running efficiently over time.
-
-For setup instructions, see [Configure Nomad GC settings](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-server/deployment-options/docker/env_var.md#nomad-garbage-collection-gc-settings).
-
-### New “Stale PBM Backup” alert template
-
-Added a new alert template **Stale PBM Backup**, which triggers when no successful backup has occurred within your configured time window.
-
-This helps you ensure MongoDB backups run on schedule.
-
-For details, see [Percona Backup for MongoDB templates](https://docs.percona.com/percona-monitoring-and-management/3/alert/templates_list.md#pbm-percona-backup-for-mongodb-templates).
-
-## Components upgrade
-
-### ClickHouse 25.3.6.56
-
-Upgraded from 23.8.2.7 to fix **CVE-2024-24790**. The new build uses Go 1.24.9, removes the vulnerable `clickhouse-diagnostics` tool, and includes performance, storage, and security improvements.
-
-### Go runtime 1.24.9
-
-All PMM components now use Go 1.24.9, resolving the following vulnerabilities in Go 1.24.7 (CVE-2025-47912, CVE-2025-58183, CVE-2025-58186, CVE-2025-58187, CVE-2025-58188, CVE-2025-61724). This update also provides general performance improvements.
-
-### Watchtower
-
-Upgraded to support Docker API 1.44+, resolving compatibility issues with modern Docker installations for reliable automatic PMM Server container updates.Retry
-
-## Improvements
-
-- [PMM-14348](https://perconadev.atlassian.net/browse/PMM-14348): Added **Enable QAN for PMM Server** toggle in **PMM Configuration > Settings > Advanced Settings** to easily enable or disable Query Analytics for PMM Server's internal PostgreSQL database. Previously, this required API calls. The setting can also be controlled via the `PMM_ENABLE_INTERNAL_PG_QAN` environment variable.
-
-- [PMM-14118](https://perconadev.atlassian.net/browse/PMM-14118) PMM now automatically generates SSL certificates for ClickHouse database connections to improve security and eliminate certificate error messages in ClickHouse logs.
-
-- [PMM-10461](https://perconadev.atlassian.net/browse/PMM-10461): Improved compatibility with proxy servers. All Nginx redirects now use relative paths instead of a mix of absolute and relative redirects. This prevents issues with external proxies and aligns behavior with Grafana.
-
-- [PMM-6659](https://perconadev.atlassian.net/browse/PMM-6659): Query Analytics now hides PMM Server's internal PostgreSQL queries by default, keeping the view focused on your monitored databases. You can re-enable this in **PMM Configuration > Settings > Advanced Settings** for troubleshooting or HA scenarios.
-
-- [PMM-13782](https://perconadev.atlassian.net/browse/PMM-13782): We've removed **MySQL Query Response Time Details** from the main navigation menu. You can still access this dashboard in **Dashboards > MySQL** if you're a MariaDB user with the Query Response Time plugin enabled. This change streamlines your navigation experience, as the dashboard only supports outdated Percona Server for MySQL 5.7. If you're using MySQL 8.0 or later, use Query Analytics (QAN) with Performance Schema.
-
-- [PMM-14108](https://perconadev.atlassian.net/browse/PMM-14108): Added idle connections metric to the **Connections** panel available in **MongoDB Cluster Summary** and **Replica Set Summary** dashboards. Idle connections are now displayed alongside Available and Current connections to help identify potential performance issues.
-
-- [PMM-14107](https://perconadev.atlassian.net/browse/PMM-14107): Renamed the **Query Execution Times** panel to **Operation Latencies** in **MongoDB Router Summary**, **Sharded Cluster Summary**, and **Replica Set Summary** dashboards to better reflect the actual metrics being displayed.
-
-- [PMM-14271](https://perconadev.atlassian.net/browse/PMM-14271): Fixed misleading status indicators for disabled agents in PMM Inventory. Disabled agents now display Disabled status with grey background instead of **Unknown**, clearly indicating they are intentionally disabled rather than failing. The **Services** tab **Monitoring** status has been improved: services show OK (green) when only non-critical agents are disabled, Warning (orange) when multiple agents are disabled, and Failed (red) when agents are actually failing.
-
-- [PMM-14006](https://perconadev.atlassian.net/browse/PMM-14006): Added **Disable query examples** checkbox when adding MySQL and PostgreSQL services. Enable this to prevent PMM from collecting full SQL queries with literal data values in Query Analytics, showing only query fingerprints instead. Available under **PMM Configuration > PMM Inventory > Add Service > Advanced Settings**.
-
-- [PMM-14231](https://perconadev.atlassian.net/browse/PMM-14231): PMM now automatically includes a type label (`logical` or `physical`) in PBM backup metrics, so you can easily identify backup types and troubleshoot MongoDB backups more efficiently.
-
-- [PMM-14006](https://perconadev.atlassian.net/browse/PMM-14157): Added the ***Stale PBM Backup** alert template to monitor missed or delayed MongoDB backups.
-
-- [PMM-14355](https://perconadev.atlassian.net/browse/PMM-14355): Updated the **Home Dashboard** to show Valkey/Redis service counts in the **Monitored DB Services** and **Monitored DB Instances** panels. The layout was adjusted to prevent text overlap and hide services with a “0” count for a cleaner, more accurate overview.
-
-- [PMM-14309](https://perconadev.atlassian.net/browse/PMM-14309): We’ve removed the **Connect to Percona Platform** banner to simplify the Advisors interface and reflect PMM’s new built-in, offline advisors.
-
-- [PMM-13943](https://perconadev.atlassian.net/browse/PMM-13943): Added unique identifiers (UIDs) for datasources Each datasource now has a fixed UID defined in datasources.yml. This prevents Grafana from generating random UIDs during provisioning and ensures consistent references across dashboards, upgrades, and alerts.
-
-- [PMM-13781](https://perconadev.atlassian.net/browse/PMM-13781): Updated the navigation menu to remove the outdated **TokuDB** entry and restore **MyRocks**. PMM now correctly reflects support for MyRocks, an actively used storage engine, and no longer lists the deprecated TokuDB.
-
-- [PMM-13103](https://perconadev.atlassian.net/browse/PMM-13103): PMM now allows adding remote MySQL instances using only a CA certificate, without requiring client certificate and key files. This simplifies TLS setup and enables monitoring for services like Azure MySQL Flexible Server and Google Cloud SQL (MySQL) using a single certificate.
-
-## Fixed issues
-
-- [PMM-14305](https://perconadev.atlassian.net/browse/PMM-14305): Fixed QAN service failures during PMM Server upgrades caused by interrupted database schema migrations. When the ClickHouse schema migration was interrupted, QAN would fail to start with "Dirty database version x" errors. PMM now automatically detects and completes the interrupted migration, allowing QAN dashboards to load normally.
-
-- [PMM-14022](https://perconadev.atlassian.net/browse/PMM-14022): Fixed duplicate service counts in MongoDB dashboards and the MongoDB down alert rule on the **Alert rules** page caused by high-resolution and low-resolution exporter jobs being counted separately.
-
-- [PMM-14106](https://perconadev.atlassian.net/browse/PMM-14106): Fixed **MongoDB Command Operations** and **Collection Details** panels in **Replica Set Summary**, **Cluster Summary**, and **Router Summary** dashboards to correctly apply the node filter selection. The panels now display data only for the selected node instead of always showing all nodes.
-
-- [PMM-14504](https://perconadev.atlassian.net/browse/PMM-14504): Fixed an issue where QAN stopped working after adding or removing columns. QAN now handles column additions and removals correctly without triggering *"No queries available for this combination of filters"* errors.
-
-- [PMM-14498](https://perconadev.atlassian.net/browse/PMM-14498): Fixed an issue where adding external services using `pmm-admin add external` would fail with an internal server error. You can now add external services successfully through both the command line and the user interface.
-
-- [PMM-14435](https://perconadev.atlassian.net/browse/PMM-14435): Fixed Nginx routing issue that showed *"Unauthorized"* error instead of redirecting you to the login page when accessing PMM Server for the first time or after session expiration.
-
-- [PMM-14430](https://perconadev.atlassian.net/browse/PMM-14430): Fixed the **Execution Time** panel in the **PostgreSQL Instances Overview** dashboard that was not displaying any data. The panel now correctly shows execution time metrics for all PostgreSQL services.
-
-- [PMM-14265](https://perconadev.atlassian.net/browse/PMM-14265): Fixed an issue where the **MongoDB Router Summary** dashboard showed the Kubernetes node uptime instead of the actual mongos pod uptime. PMM now correctly reports the real uptime, CPU, and memory usage for each mongos pod.
-
-- [PMM-14260](https://perconadev.atlassian.net/browse/PMM-14260): Fixed an issue where PostgreSQL metrics from `queries-hr.yml` were duplicated after upgrading to PMM 3.3.1. PMM now correctly labels metrics from different databases to prevent duplication errors and ensure accurate dashboard data.
-
-- [PMM-14260](https://perconadev.atlassian.net/browse/PMM-14260): Fixed an issue preventing PMM Server from starting in OpenShift when using the `namespaceOverride` Helm option.
-
-- [PMM-14205](https://perconadev.atlassian.net/browse/PMM-14205): Fixed Helm upgrade issues from PMM 2 where the PMM Server pod failed to start due to a missing `pmm-service-account`. The Helm chart now correctly handles service account creation during upgrades. If you’re upgrading from PMM 2, make sure you use the latest `values.yaml` or explicitly set `serviceAccount.create=true`.
-
-- [PMM-14134](https://perconadev.atlassian.net/browse/PMM-14134): Fixed a bug in the **MySQL Replication Summary dashboard** where the **SQL Delay** metric in the **Replication Lag** panel could show incorrect values. It now accurately reflects the selected time range.
-
-- [PMM-14081](https://perconadev.atlassian.net/browse/PMM-14081): Corrected a typo in the `azure_database_exporter` that prevented monitoring of Azure Database for MySQL Flexible Server instances. These servers are now properly discovered and monitored.
-
-- [PMM-14071](https://perconadev.atlassian.net/browse/PMM-14071): Fixed broken **Service Summary** chart in the **MongoDB Instance Summary** dashboard that showed an error instead of data. It now displays metrics correctly.
-
-- [PMM-14014](https://perconadev.atlassian.net/browse/PMM-14014): The **Open Source** link in the **Help** menu now correctly opens the Grafana OSS page in a new tab.
-
-- [PMM-11406](https://perconadev.atlassian.net/browse/PMM-11406): The **Service Summary** panel in the **MongoDB Instance Summary** dashboard now loads correctly for MongoDB 6.x and newer versions.
-
-## Known issues
-
-### Docker v29.0.0 compatibility
-
-PMM 3.5.0 has limited Watchtower support for Docker v29.0.0 due to API version incompatibility. If you're using Docker v29.0.0, work around this issue by setting the following environment variable when running PMM:
-
-```sh
-docker run -e DOCKER_API_VERSION=1.45 ...
-```
-
-A full Docker v29.0.0 update to Watchtower is planned for PMM 3.6.0.
-
-### PMM Server restart issues on macOS Sequoia with Docker Desktop 4.49.0
-
-[PMM-14438](https://perconadev.atlassian.net/browse/PMM-14438): PostgreSQL and Grafana may fail to start on macOS Sequoia 15.7.1 (M2) with Docker Desktop 4.49.0. See [Troubleshooting](https://docs.percona.com/percona-monitoring-and-management/3/troubleshoot/config_issues.md#pmm-server-inaccessible-after-docker-restart-on-macos-sequoia) for diagnostic steps.

+## Release summary
+
+## Release highlights
+
+### New native PMM navigation and revamped user interface
+
+The first thing you'll notice with this update is the new look-and-feel of the PMM interface. We've moved away from Grafana's built-in menus to PMM's own navigation, organized around PMM's workflows to make it easier for you to move through PMM and find what you need faster. This brings:
+
+- A new, always-visible sidebar that provides consistent access to all PMM features without relying on Grafana’s native menus:
+
+ 
+
+- Sticky time range and variables: Selected time ranges and dashboard variables now persist when switching between dashboards, so you no longer need to reapply filters.
+
+- A new theme switcher in the sidebar applies Light or Dark mode to both the PMM interface and embedded dashboards.
+
+- Query Analytics now fully supports the light theme
+
+- Centralized Help & Resources: Quick access to documentation, the community forum, support contact, and feedback tools. Admin users also see **Dump** and **Logs** options.
+
+- New interactive onboarding tour to help first-time users explore PMM’s key features. You can start it from the Help Center’s Welcome Card or from **Useful tips > Start PMM tour**.
+
+- Clearer update reminders: small badges and pop-up messages so you can easily see when updates are available.
+
+#### You should know that:
+
+- The new navigation is enabled by default, and you will not be able to revert to the previous Grafana-based menus.
+- If you use a custom `grafana.ini` file, add [`allow_embedding = true`](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#allow_embedding) to the `[security]` section so that the new interface can display dashboards correctly.
+
+For details on navigating the new interface, see [Interface overview](https://docs.percona.com/percona-monitoring-and-management/3/reference/ui/ui_components.html) and Help Center.
+
+### Clustered High Availability with zero-downtime monitoring (Technical Preview)
+
+### Technical Preview Status
+
+```
+This feature is not production-ready. Use for testing and feedback only.
+```
+
+PMM 3.5.0 introduces PMM HA Clustered, a zero-downtime HA option for continuous monitoring visibility.
+
+PMM's two production-ready HA options ([Docker](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/HA-docker.html) and [Kubernetes single-instance](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/HA-kubernetes-single-instance.html)) work well but leave 1-5 minute monitoring gaps during failover.
+
+For enterprises needing continuous visibility, we announced development of a fully clustered architecture. That architecture is now available for testing ans delivers the core high availability features announced previously:
+
+- three PMM server replicas with Raft consensus leader election
+- HAProxy load balancing with automatic traffic routing
+- distributed databases (ClickHouse, VictoriaMetrics, PostgreSQL) via Kubernetes operators
+- Helm-based installation via Kubernetes operators
+- sub-30-second failover maintaining continuous monitoring
+
+### HA status monitoring
+
+Alongside the new clustered architecture, PMM 3.6.0 also improves visibility into HA deployments with new monitoring capabilities. Whether you're using the existing Docker or Kubernetes single-instance HA options or testing the new HA Clustered architecture, you can now track cluster health and status through:
+
+- **HA badge** on Home dashboard: shows the current leader node and overall cluster health at a glance 
+- **Inventory integration**: displays HA roles and health status for each node in your cluster: 
+- **[PMM HA Health Overview dashboard](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-ha-health-overview.html)**: provides detailed monitoring of component health, resource usage, and pod status specifically for HA Clustered deployments
+
+ 
+
+### What's still in development
+
+This Technical Preview release focuses on core clustering functionality and zero-downtime failover. Several enterprise features are still under active development and will be added in future releases as we move toward production readiness.
+
+- **Multi-region geographic distribution**: Deploy PMM HA nodes across different geographic regions for disaster recovery
+- **Production-ready stability**: Additional testing, performance optimization, and hardening for production workloads
+- **Migration paths**: Tools and procedures to migrate from existing PMM deployments to HA Clustered
+- **Horizontal scalability**: Dynamic scaling based on monitoring load and advanced disaster recovery features
+
+See [limitations and known issues](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/HA-clustered.md#known-issues) for current restrictions.
+
+### Platform Support
+
+We've tested PMM HA Clustered on Amazon EKS with Kubernetes 1.24 and later versions. While the architecture should work on other Kubernetes platforms (GKE, AKS, on-premise Kubernetes, OpenShift), we haven't validated these yet. VMware Tanzu is not supported.
+
+### Documentation and resources
+
+For installation instructions, see [Install PMM with Kubernetes HA (Clustered)](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/HA-clustered.html).
+
+For programmatic monitoring, see the new [REST API endpoints](https://percona-pmm.readme.io/reference/release-notes-3-6-0).
+
+### Provide feedback
+
+Try out this feature and share your experience on the [PMM forum] and [JIRA Tracker], regardless of your platform. Your feedback during this Technical Preview phase helps us prioritize improvements, expand our support matrix, and ensure the final release meets enterprise monitoring needs.
+
+### MongoDB dashboard improvements
+
+Based on community feedback, we've simplified several MongoDB dashboards so you can check cluster health faster and focus on the metrics that matter:
+
+- **[Instances Overview](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-mongodb-instances-overview.html)**: the **Overview** section now focuses on topology and health metrics instead of detailed resource metrics. Detailed metrics like **Cursors**, **Latency**, and **Query Efficiency** are now only available in **Instance Summary**, **Replica Set Summary**, and **Sharded Cluster Summary**.
+- **[Instance Summary](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-mongodb-instances-overview.html)**: clearer **Uptime**, **QPS**, and **Latency** panels with one-decimal precision. The **Command Operations** panel now includes additional metrics.
+- **[Router Summary](https://docs.percona.com/percona-monitoring-and-management/3/reference/dashboards/dashboard-mongodb-router-summary.html)**: improved decimal precision across metrics. A new **Routers** panel at the top shows router status at a glance for quick cluster visibility:
+
+ 
+
+### Redesigned MongoDB Backup Details dashboard
+
+We've redesigned the **MongoDB PBM Details** dashboard with new and enhanced panels that make it easier to monitor your backup agents and track operations across your environment. You'll find it under its new name, **MongoDB Backup Details**, which better reflects what the dashboard now offers.
+
+**New panels:**
+
+- **Backup Agents**: See how many PBM agents are currently being monitored across your environment.
+- **Backup Agent Summary**: Quickly assess the overall health of your backup infrastructure with a donut chart showing agent status distribution.
+- **Backup Agent Status**: Identify problematic agents at a glance using a hexagon grid that highlights which specific hosts need attention.
+
+**Enhanced panels:**
+
+- **Backup agent status over time**: Spot patterns and troubleshoot issues by viewing how agent status has changed over your selected time range.
+- **Backup history**: Get a complete picture of backups across your MongoDB infrastructure with new columns for Environment, Cluster/Replica Set, Size, and Duration.
+
+
+
+To explore this dashboard, go to **MongoDB > MongoDB Backup Details** in the sidebar.
+
+### Added support and deprecations
+
+#### PostgreSQL 18 support on RHEL 10
+
+Extending the RHEL 10 support introduced in PMM 3.4.0, you can now also monitor PostgreSQL 18 databases on Red Hat Enterprise Linux 10. To get started, [install PMM Client](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/package_manager.html) on your AMD64 or ARM64 system.
+
+#### Debian 13 support for PMM Client
+
+PMM Client now supports Debian 13 (Trixie) so you can monitor databases on the latest Debian release (AMD64 and ARM64). For installation instructions, see [Install PMM Client with Package Manager](https://docs.percona.com/percona-monitoring-and-management/3/install-pmm/install-pmm-client/package_manager.html).
+
+## Security updates
+
+## Components upgrade
+
+### Nomad v1.11.0
+
+Upgraded from v1.10.5 with security enhancements and new features including improved client identity management for RPC authentication, token-based client introduction, and system job deployment support. See the [Nomad v1.11.0 release notes](https://developer.hashicorp.com/nomad/docs/release-notes/nomad/v1-11-x) for details.
+
+## Improvements
+- [PMM-14375](https://perconadev.atlassian.net/browse/PMM-14375): Added `--agent-env-vars` flag to `pmm-admin` add commands. Use this to pass environment variables from `pmm-agent` to exporters when your monitoring setup requires environment-level credentials or configuration.
+
+- [PMM-14528](https://perconadev.atlassian.net/browse/PMM-14528): Updated Watchtower and Docker API libraries with full Docker v29.0.0 support. The `DOCKER_API_VERSION` workaround is no longer required. If you're using an older watchtower version and see `client version is too old` errors, see [Troubleshoot upgrade issues](https://docs.percona.com/percona-monitoring-and-management/3/troubleshoot/upgrade_issues.md#watchtower-fails-with-client-version-is-too-old-error).
+
+## Fixed issues
+
+- [PMM-14378](https://perconadev.atlassian.net/browse/PMM-14378): Fixed `waitid: no child processes` error that could occasionally occur when registering PMM Client (Docker distribution) with PMM Server.
+
+- [PMM-14321](https://perconadev.atlassian.net/browse/PMM-14321): Fixed a PMM Agent crash triggered when parsing slow query log entries containing queries that use `Value` as a column alias.
+
+- [PMM-14440](https://perconadev.atlassian.net/browse/PMM-14440): Fixed `excessive was collected before with the same name and label values` errors in `mysqld_exporter` logs that caused rapid log file growth.
+
+- [PMM-14568](https://perconadev.atlassian.net/browse/PMM-14568): Fixed `container is not a PMM server` error when upgrading PMM Server via the UI. This occurred when the image name was different from `pmm-server`.
+
+- [PMM-10308](https://perconadev.atlassian.net/browse/PMM-10308): Fixed missing metric queries in the **MySQL Instance Summary** dashboard that caused several panels to show `N/A` instead of actual values.
+
+- [PMM-14573](https://perconadev.atlassian.net/browse/PMM-14573): Fixed a connection leak in MongoDB exporter that could exhaust connections and crash MongoDB nodes when replica set members were unreachable.
+
+- [PMM-145343](https://perconadev.atlassian.net/browse/PMM-145343): Fixed duplicate and misleading panel names on the **MySQL Instances Overview** dashboard by renaming one of the panels from **MySQL Temporary Objects** to **Top 5 MySQL Temporary Objects**, so each panel now clearly reflects the metrics it displays.
