# Atlas Changelog

## 2026 Releases

### October 2026

- Adds user settings to the Atlas UI Data Explorer. You can now configure the time zone for date display, read-only mode, the default `maxTimeMS` for queries, and the display format for legacy UUID values. Your settings persist across all of your Data Explorer sessions. To learn more, see [Atlas UI User Settings.](https://www.mongodb.com/docs/atlas/atlas-ui.md#std-label-data-explorer-settings)

- Adds invited federated users directly to your organization as active members when you use SAML federation and their email domain matches a verified domain in your identity provider configuration, so they no longer need to accept an invitation. To learn more, see [Inviting Federated Users.](https://www.mongodb.com/docs/atlas/invitations.md#std-label-inviting-federated-users)

### September 2026

- Public Preview: Releases Atlas Infinite, an Atlas database edition that separates compute from storage into independent layers. To learn more, see [MongoDB Atlas Infinite: Overview.](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-landing.md#std-label-atlas-infinite-edition)

- General Availability: Adds [Intelligent Workload Management](https://www.mongodb.com/docs/atlas/intelligent-workload-management.md#std-label-intelligent-workload-management), which protects cluster availability during overload by queuing operations, prioritizing critical work, and shedding excess operations as a last resort. To adjust the protections that apply to your cluster, see [Configure Load Shedding.](https://www.mongodb.com/docs/atlas/intelligent-workload-management.md#std-label-configure-iwm)

- General Availability: Adds support for connecting [Atlas SQL](https://www.mongodb.com/docs/sql-interface/) directly to a Dedicated cluster, so you can use the SQL interface without configuring Atlas Data Federation.

- Adds support for streaming [Activity Feed events](https://www.mongodb.com/docs/atlas/export-events.md#std-label-export-events) to external tools. You can export events from the Project Activity Feed to AWS (Amazon Web Services) S3 (Simple Storage Service), Azure Blob Storage, Datadog, Google Cloud Storage, Splunk, or any OpenTelemetry-compatible destination, and events from the Organization Activity Feed to OpenTelemetry-compatible destinations.

- Adds support for write operations in [Query Shape Insights](https://www.mongodb.com/docs/atlas/query-shape-insights.md#std-label-query-shape-insights), which previously covered only `find` and `aggregate` commands. You can now diagnose the performance of `update`, `insert`, and `delete` commands.

- Improves throughput for operations that require an optimized initial sync on AWS (Amazon Web Services), such as adding or replacing nodes, adding regions, and creating or rebuilding shards. To learn more, see [Enable or Disable Fast Disk Pre-Warming.](https://www.mongodb.com/docs/atlas/cluster-additional-settings.md#std-label-disk-pre-warming)

- General Availability: Adds Gen2 support for `M30+` Dedicated clusters on Google Cloud, allowing you to scale disk storage capacity and storage performance (IOPS (Input/Output Operations per Second) and throughput) independently for improved cost optimization. To learn more, see [Gen2 Dedicated clusters.](https://www.mongodb.com/docs/atlas/manage-clusters.md#std-label-gen2-clusters)

- Allows you to sign in to Atlas from MongoDB Compass and approve delegated access, so the [intelligent assistant](https://www.mongodb.com/docs/compass/current/query-with-natural-language/compass-ai-assistant.md#std-label-compass-ai-assistant) can use your existing Atlas permissions to inspect Atlas metadata and provide targeted troubleshooting when a MongoDB Compass connection fails.

- Adds a [Shell Syntax Mode](https://www.mongodb.com/docs/atlas/atlas-ui/documents.md#std-label-atlas-ui-insert-documents) for inserting and editing documents in the Atlas UI and MongoDB Compass, so you can use consistent MongoDB shell syntax with unquoted field names and type constructors such as `ObjectId()` and `ISODate()` instead of switching between shell and EJSON syntax.

- Removes the option to enable the BI Connector for new and existing clusters ahead of its end of life. To query your data with SQL, use [Atlas SQL](https://www.mongodb.com/docs/sql-interface/) instead.

- Publishes the [end-of-life plan](https://www.mongodb.com/docs/atlas/push-logs.md#std-label-pble-eol) for [Push-Based Log Export](https://www.mongodb.com/docs/atlas/push-logs.md#std-label-mongodb-logs-push), which reaches end of life on February 4, 2027 and stops accepting new configurations on October 30, 2026. To migrate to external log sinks, see [Export Logs to AWS (Amazon Web Services) S3 (Simple Storage Service) Buckets.](https://www.mongodb.com/docs/atlas/export-logs-external-sinks.md#std-label-export-logs-external-sinks)

- Improves the metrics experience in the Atlas UI with a uniform interface and consistent controls for metrics charts across all dedicated cluster architectures, so you can correlate metrics with events and alerts when you monitor your deployment. To learn more, see [cluster metrics.](https://www.mongodb.com/docs/atlas/review-all-cluster-metrics.md#std-label-review-all-cluster-metrics)

- General Availability: Adds support for Voyage AI embedding and reranking inference in the Europe Geography, so you can keep inference traffic within the EU for data residency. To learn more, see [Voyage AI Geographies.](https://www.mongodb.com/docs/voyageai/geographies/)

- Enables you to use [LDAP authorization](https://www.mongodb.com/docs/atlas/security-ldaps.md#std-label-security-ldaps) alongside other external authentication mechanisms, including AWS (Amazon Web Services) IAM, X.509, and OIDC, so you can combine authentication mechanisms in a single deployment.

### August 2026

- General Availability: Adds a [FOCUS Cost and Usage Report](https://www.mongodb.com/docs/atlas/billing/focus-report.md#std-label-focus-report-overview) that presents your billing cost and usage data in the industry-standard FinOps Open Cost and Usage Specification (FOCUS) 1.3 format, so you can reconcile and integrate your billing data with FinOps and cross-vendor cost-management tools.

- Allows you to manage indexes in [Data Explorer](https://www.mongodb.com/docs/atlas/atlas-ui/indexes.md#std-label-atlas-ui-indexes) when you have the [Project Index Manager role](https://www.mongodb.com/docs/atlas/reference/user-roles.md#std-label-project-roles) combined with the Project Data Access Read Only or Project Data Access Read/Write role, so you can grant granular access to index controls without granting access to data.

- Updates the default number of [cross-region network permissions](https://www.mongodb.com/docs/atlas/reference/faq/networking.md#std-label-faq-cross-region) for new projects from 40 to 100. Existing projects are unchanged.

- Adds alerts that notify you when your cluster is impacted by [connection rate limits](https://www.mongodb.com/docs/atlas/reference/atlas-limits.md#std-label-connection-rate-limits), so you can identify when your clients are offering more new connections than your cluster can process and act before connections are dropped.

### July 2026

- Reverts the Atlas UI read preference back to reading from the primary unless the primary is unavailable. This restores the behavior that was in place before March 2026.

- Improves Atlas resiliency during cloud provider regional outages. When you start a scaling or region-change operation that requires tearing down resources in an unhealthy region, Atlas now bypasses that teardown safely instead of stalling, so your operation completes without manual intervention. To learn more, see [Reconfigure a Replica Set During a Regional Outage.](https://www.mongodb.com/docs/atlas/reconfigure-replica-set-during-regional-outage.md#std-label-reconfigure-rs-during-regional-outage)

- Extends [data validation](https://www.mongodb.com/docs/atlas/data-validation.md#std-label-data-validation) coverage to clusters that use CMK (customer-managed key). Atlas runs data validation automatically as a background job to detect silent data corruption, so this requires no action from you.

- General Availability: Adds support for additional payment methods in [Atlas billing](https://www.mongodb.com/docs/atlas/billing.md#std-label-atlas-billing), including Link, ACH, SEPA Direct Debit, Google Pay, and Revolut, in addition to existing credit card and PayPal options.

- General Availability: Adds support for Collection- and Database-Level Restore, allowing you to restore an individual database or collection directly into a live cluster through the Atlas UI or the [Atlas Administration API](https://www.mongodb.com/docs/atlas/backup/cloud-backup/restore-from-db-coll.md#std-label-restore-from-db-coll). This gives you fine-grained control over recovery workflows, so you can fix isolated data issues without affecting the rest of your application.

- Improves performance of the [Projects page](https://www.mongodb.com/docs/atlas/tutorial/manage-projects.md#std-label-manage-projects) by adding pagination, helping you load and navigate large lists of projects more quickly.

- Adds support for setting an operations contact for your Atlas organization, similar to existing security and billing contacts. This contact, which does not need to be an Atlas user, receives operational notifications from MongoDB.

- Adds support for downloading cloud backup snapshots through a private endpoint for Google Cloud, matching existing AWS (Amazon Web Services) and Azure (Microsoft Azure) support. This enhances security by keeping backup download traffic off the public internet.

- Adds automatic scaling of the maximum oplog size on dedicated clusters that use EBS (non-NVMe) storage. When you change the storage size, Atlas now resizes the oplog to match the new disk size, even if you never set a custom oplog size. To learn more, see [Oplog Size Behavior.](https://www.mongodb.com/docs/atlas/customize-storage.md#std-label-oplog-size-behavior)

### June 2026

- Adds cross-region support for AWS PrivateLink when you [export backup snapshots to Amazon S3](https://www.mongodb.com/docs/atlas/backup/cloud-backup/export.md#std-label-cloud-provider-snapshot-export), so you can distribute snapshots to S3 (Simple Storage Service) buckets in other AWS (Amazon Web Services) regions while keeping all export traffic on private endpoints and private IP (Internet Protocol)s.

- Adds cost-effective [Extended Standard IOPS](https://www.mongodb.com/docs/atlas/customize-storage.md#std-label-extended-iops-gen2) for AWS (Amazon Web Services) Gen2 Dedicated clusters. You can provision IOPS (Input/Output Operations per Second) above the baseline your disk storage already includes, without moving to a higher-cost IOPS (Input/Output Operations per Second) option.

- Updates the storage capacity display for Gen2 Dedicated clusters with local [NVMe SSDs](https://www.mongodb.com/docs/atlas/nvme-storage.md#std-label-nvme-storage) to use GiB instead of GB, matching the unit that other cluster tiers already use. Existing AWS Gen1 clusters continue to display storage in GB.

### May 2026

- Adds support for AWS PrivateLink cross-region connectivity. You can now [configure which regions can connect to your private endpoint service](https://www.mongodb.com/docs/atlas/security-private-endpoint.md#std-label-manage-accepted-endpoint-regions). Applications in different AWS (Amazon Web Services) regions can now connect to your Atlas clusters through private endpoints.

- Improves the performance of Data Explorer connection experience.

- Adds support for retrieving expired and rejected organization and project invitations through the API (Application Programming Interface).

- General Availability: Stores source fields in the [Atlas Vector Search](https://www.mongodb.com/docs/search/query/operators-collectors/vectorSearch.md#std-label-fts-vectorSearch-ref) index to reduce query latency, which eliminates unnecessary document fetches during query execution.

- Public Preview: Adds `$similarityCosine`, `$similarityDotProduct`, and `$similarityEuclidean` aggregation expressions that compute exact vector similarity between two vectors within an aggregation pipeline, without requiring a vector search index.

- Public Preview: Extends the `$similarityCosine`, `$similarityDotProduct`, and `$similarityEuclidean` aggregation expressions to accept BinData vectors directly, improving performance by eliminating array conversion.

- Adds a [`$meta`](https://www.mongodb.com/docs/manual/reference/operator/aggregation/meta.md#mongodb-expression-exp.-meta) keyword `searchRootDocumentId` field when you use the [Atlas Search](https://www.mongodb.com/docs/search.md#std-label-atlas-search) `returnScope` operator for searching nested data.

- Public Preview: Enables automated text embedding in [Atlas Vector Search](https://www.mongodb.com/docs/search/query/operators-collectors/vectorSearch.md#std-label-fts-vectorSearch-ref) using Voyage AI models, which eliminates the need for a separate embedding pipeline when performing semantic search on text data.

- General Availability: Improves [Hierarchical Navigable Small Worlds](https://arxiv.org/abs/1603.09320) index correctness in [Atlas Vector Search](https://www.mongodb.com/docs/search/query/operators-collectors/vectorSearch.md#std-label-fts-vectorSearch-ref) by adding new `hnswOptions` index configurations (`maxEdges`, `numEdgeCandidates`) that let advanced users tune graph construction for higher recall.

- Adds Atlas Stream Processing support in four new cloud regions: Microsoft Azure Brazil South (`brazilsouth`), Microsoft Azure Australia East (`australiaeast`), AWS (Amazon Web Services) EU West 3 (`eu-west-3`), and Google Cloud US East 4 (`us-east4`).

- General Availability: Routes identical queries to the same search node using consistent hashing, which produces deterministic results, to improve the consistency of MongoDB Vector Search query results on search nodes.

- Adds support for customer-managed key encryption on dedicated MongoDB Search nodes in Microsoft Azure, which enables you to use your own encryption keys to protect search node data at rest. To learn more, see [Encryption at Rest using Customer Key Management.](https://www.mongodb.com/docs/atlas/security-kms-encryption.md#std-label-security-kms-encryption)

### April 2026

- Adds support for Google Cloud Pub/Sub as a sink in [Atlas Stream Processing](https://www.mongodb.com/docs/atlas/atlas-sp/overview/), allowing you to stream data with GCP Private Service Connect for private network connectivity.

- Public Preview: Adds support for the `$rerank` operator in [Atlas Search](https://www.mongodb.com/docs/search.md#std-label-atlas-search), enabling semantic re-ranking of search results to improve relevance.

- Adds additional metrics to the [third-party DataDog integration](https://www.mongodb.com/docs/atlas/tutorial/datadog-integration.md#std-label-datadog-integration), including database and namespace-level metrics for enhanced observability.

- Public Preview: Adds support for [vector field type](https://www.mongodb.com/docs/search/indexes/field-types/vector-type.md#std-label-bson-data-types-vector) on arrays of embeddings, enabling semantic search across nested subdocuments containing multiple embedding vectors.

- Adds support for automated Voyage AI embeddings in the LangChainJS framework, enabling you to use MongoDB [auto-embedded vector search indexes](https://www.mongodb.com/docs/search/indexes/field-types/embedded-documents-type.md#std-label-bson-data-types-embedded-documents) with JavaScript applications.

- Enables [cloud backup](https://www.mongodb.com/docs/atlas/backup/cloud-backup/overview.md#std-label-backup-cloud-provider) support for clusters deployed in the Microsoft Azure government environment.

- Enables configurable sampling for data model inference in [Compass](https://www.mongodb.com/try/download/compass) and Data Explorer. Specify the number of documents Atlas samples when inferring a collection's schema. To learn more, see [Data Modeling in Atlas.](https://www.mongodb.com/docs/atlas/atlas-ui/data-modeling.md#std-label-atlas-ui-data-modeling)

- Adds the uncompressed data size alongside compressed storage size for each collection in Data Explorer. Compare these sizes to identify collections with the most potential for space reclamation after compression. To learn more, see [View Collections.](https://www.mongodb.com/docs/atlas/atlas-ui/collections.md#std-label-atlas-ui-view-collections)

- Adds CPU time to [Query Shape Insights](https://www.mongodb.com/docs/atlas/query-shape-insights.md#std-label-query-shape-insights), allowing you to identify and optimize resource-intensive operations and prioritize queries for cluster resource optimization.

- Improves [independent shard scaling](https://www.mongodb.com/docs/atlas/cluster-sharding.md#std-label-atlas-cluster-sharding) by removing the two-tier zone gap limitation at the cluster level and adding support for asymmetric auto-scaling range configurations.

### March 2026

- Introduces MongoDB Agent Skills, a package that injects MongoDB-specific engineering standards into AI agent development environments. The package provides six specialized capabilities covering schema design, query optimization, indexing, aggregation pipelines, data modeling, and Atlas configuration. To learn more, see [Build AI Agents with MongoDB.](https://www.mongodb.com/docs/vector-search/about/ai-agents.md#std-label-ai-agents)

- Adds support for high CPU (Central Processing Unit), low CPU (Central Processing Unit), and storage-optimized instance types for [Search nodes](https://www.mongodb.com/docs/search/deployment/deployment-options.md#std-label-what-is-search-node) in additional AWS (Amazon Web Services) regions, including `AP_SOUTHEAST_5`, `AP_SOUTHEAST_1`, `EU_WEST_3`, `EU_SOUTH_2`, `AF_SOUTH_1`, `AP_EAST_1`, `AP_SOUTH_2`, `AP_SOUTHEAST_3`, `AP_SOUTHEAST_7`, `EU_SOUTH_1`, `EU_CENTRAL_2`, `IL_CENTRAL_1`, `MX_CENTRAL_1`, `ME_CENTRAL_1`, and `AP_SOUTHEAST_2`.

- Improves [disk auto-scaling](https://www.mongodb.com/docs/atlas/cluster-autoscaling.md#std-label-cluster-autoscaling) to trigger during long-running operations such as shard drain operations, preventing clusters from running out of disk space without requiring manual intervention.

- Adds support for sending all [Atlas logs](https://www.mongodb.com/docs/atlas/export-logs-external-sinks.md#std-label-export-logs-external-sinks), including MongoDB Search and Atlas Stream Processing logs, directly to Datadog, Splunk, Google Cloud Cloud Storage, Microsoft Azure Blob Storage, and any OpenTelemetry-compatible vendor, making it easier to analyze MongoDB logs alongside other telemetry in your existing observability platform.

- Introduces a new alert that fires when a potentially dangerous [database profiler](https://www.mongodb.com/docs/manual/reference/database-profiler.md#std-label-profiler) configuration is detected on your cluster, such as profiling all operations or profiling with a zero-millisecond threshold. This alert helps prevent unintended performance degradation on production workloads.

- Adds an automatic copy region option for [snapshot distribution](https://www.mongodb.com/docs/atlas/backup/cloud-backup/snapshot-distribution.md#std-label-snapshot-distribution), allowing Atlas to automatically copy backups to all regions in your cluster and keep copy destinations in sync as your cluster topology changes, reducing the risk of gaps in regional backup coverage.

- Removes the Search Query Analytics feature from Atlas. Related developer content and documentation have been retired.

- Improves Intelligent Workload Management [write blocking](https://www.mongodb.com/docs/atlas/intelligent-workload-management.md#std-label-iwm-always-on-protections) to use dynamic range-based thresholds instead of static values, reducing unnecessary write blocking during disk scaling operations.

- Enables backup support for Dedicated clusters deployed in Microsoft Azure that have data exfiltration prevention policies enabled, allowing you to take backups while enforcing preventative controls against data exfiltration.

- Updates the Atlas UI read preference to default to [`secondaryPreferred`](https://www.mongodb.com/docs/manual/core/read-preference.md#mongodb-readmode-secondaryPreferred). This change was reverted in July 2026.

### February 2026

- Improves performance of Microsoft Azure clusters larger than 512 GB.

- Adds support for [lexical prefilters](https://www.mongodb.com/docs/vector-search/query/aggregation-stages/vector-search-stage.md#std-label-vectorSearch-agg-pipeline-filter) in MongoDB Vector Search, enabling accelerated queries by reducing unnecessary computational load during query time.

- Standardizes Atlas Administration API [rate limiting](https://www.mongodb.com/docs/atlas/api/api-rate-limit.md#std-label-api-rate-limiting) to use the Token Bucket Algorithm. Rate limits vary by endpoint set and scope (organization, project, user, or IP address). This approach provides predictable performance with burst capability and adds response headers that offer visibility into rate limit quotas, current usage, and reset times.

- Adds port mapping support for [Google Private Service Connect (PSC)](https://www.mongodb.com/docs/atlas/security-private-endpoint.md#std-label-private-endpoint-concepts), enabling more flexible network configurations for clusters using GCP private endpoints.

- Introduces new granular [built-in roles](https://www.mongodb.com/docs/atlas/reference/user-roles.md#std-label-user-roles) for improved security posture, allowing finer control over user permissions.

- Adds `twoPhaseCommitCoordinator` metrics to the [Datadog integration](https://www.mongodb.com/docs/atlas/tutorial/third-party-service-integrations.md#std-label-third-party-integrations), providing visibility into two-phase commit operations.

- Adds support for secretless authentication when using Microsoft Azure Key Vault with [Encryption at Rest](https://www.mongodb.com/docs/atlas/security-kms-encryption.md#std-label-security-kms-encryption). Instead of providing static credentials, you authorize an Atlas-managed Microsoft Azure Service Principal that authenticates using short-lived OAuth 2.0 tokens. This eliminates the need to create, store, and rotate client secrets.

  This update also introduces support for unversioned Key Vault key URIs (`/keys/<key-name>`), which automatically resolve to the latest enabled key version.

  To learn more, see [Manage Customer Keys with Azure Key Vault (Secretless).](https://www.mongodb.com/docs/atlas/security/azure-kms-secretless.md#std-label-security-azure-kms-secretless)

- Improves cluster scaling operations by allowing disk upscaling to proceed even when unrelated capacity constraints exist, reducing unnecessary delays during cluster updates.

- Adds quality and usability improvements to the [Data Model Visualization](https://www.mongodb.com/docs/atlas/atlas-ui/data-modeling.md#std-label-atlas-ui-data-modeling) feature, making it easier to understand your data structures.

- Adds support for SSE-KMS encryption when [exporting Atlas logs to Amazon S3](https://www.mongodb.com/docs/atlas/export-logs-external-sinks.md#std-label-export-logs-external-sinks), allowing you to use your own AWS KMS keys for log encryption.

- Enables sending database and audit logs directly to Amazon S3 for long-term storage and compliance requirements.

- Adds reCAPTCHA Breached Password Detection to help prevent use of compromised passwords during account creation and password changes.

### January 2026

- Adds visibility into alert severity levels with the ability to override default severity settings for individual alert types.

- Reduces network transfer costs for [MongoDB Search](https://www.mongodb.com/docs/search.md#std-label-atlas-search) nodes by optimizing data replication between search node instances.

- Adds new alerting for clusters using [Encryption at Rest](https://www.mongodb.com/docs/atlas/security-kms-encryption.md#std-label-security-kms-encryption) when nodes cannot start due to KMS network access issues. This helps identify misconfigured KMS IP access lists that prevent cluster nodes from starting successfully.

- Improves automatic recovery for clusters using [Encryption at Rest](https://www.mongodb.com/docs/atlas/security-kms-encryption.md#std-label-security-kms-encryption). Clusters can now automatically recover after a KMS key becomes available again, even when cluster processes are disabled.

- Updates index build completion notifications to clearly identify MongoDB Vector Search indexes and provide relevant documentation links for running your first vector search query.

- Adds the ability to view plan details, including trigger information, when reviewing cluster configurations.

- Introduces experimental solution modals in [Query Profiler](https://www.mongodb.com/docs/atlas/tutorial/query-profiler.md#std-label-query-profiler) that suggest indexing solutions for unindexed queries.

- Allows you to retain existing [cloud backups](https://www.mongodb.com/docs/atlas/backup-restore-cluster.md#std-label-cloud-backup-overview) when disabling cloud backup on a cluster.

- General Availability: [MongoDB Assistant for Cluster Builder](https://www.mongodb.com/docs/atlas/ai-cluster-assistant.md#std-label-atlas-ai-cluster-assistant) helps you configure optimal cluster settings using natural language.

- Adds [cloud backup](https://www.mongodb.com/docs/atlas/backup-restore-cluster.md#std-label-cloud-backup-overview) support for GCP clusters with data exfiltration prevention policies enabled.

## 2025 Releases

### 10 December 2025 Release

- Updates Cloud Backup to automatically take an on-demand snapshot when you change the Highest Priority provider or region in a cluster with Cloud Backup enabled. Atlas stores this snapshot in the new primary region. To learn more, see [Change the Highest Priority Provider or Region.](https://www.mongodb.com/docs/atlas/cluster-config/multi-cloud-distribution.md#std-label-change-highest-priority-provider-region)

- Adds support for changing your cluster's [highest priority region](https://www.mongodb.com/docs/manual/reference/glossary.md#std-term-highest-priority-region) to a region configured for [copy snapshot distribution](https://www.mongodb.com/docs/atlas/backup/cloud-backup/snapshot-distribution.md#std-label-snapshot-distribution). Atlas automatically updates your Cloud Backup snapshot copy policy to distribute snapshot copies to the original primary region (now a secondary region).

- Adds support for enforcing cluster topology (replica set, sharded cluster, or Global cluster), disk size, and number of shards with [Atlas Resource Policies.](https://www.mongodb.com/docs/atlas/atlas-resource-policies.md#std-label-atlas-resource-policies-overview)

### 05 December 2025 Release

- Deprecates `$search.tracking` and Query Analytics UI. The official end-of-life and complete removal of support will occur in February 2026. Therefore, Atlas will no longer collect query data for display in the Atlas UI for all `$search.tracking` requests. If you have any questions or need further assistance, reach out to our support team from the MongoDB Support Portal or contact your Account Executive.

### 19 November 2025 Release

- Adds support for deploying Atlas clusters on AWS (Amazon Web Services) regions `ap-east-2` and `ap-southeast-6`, and Microsoft Azure regions `chilecentral`, `indonesiacentral`, and `malaysiawest`.

- Reduces the inactivity policy for pausing inactive Atlas Free clusters from 60 to 30 days. You'll receive an email notification 7 days before Atlas pauses your cluster. To resume a paused cluster, see [Resume One Cluster](https://www.mongodb.com/docs/atlas/pause-terminate-cluster.md#std-label-resume-cluster). If you don't plan on using your cluster in the next few weeks, we recommend [exporting](https://www.mongodb.com/docs/database-tools/mongodump.md#std-label-mongodump) the data and [terminating](https://www.mongodb.com/docs/atlas/pause-terminate-cluster.md#std-label-terminate-cluster) the cluster.

- Adds a configurable expiration duration for regional outage simulations to solve stuck simulations. You can select a duration of 1 day, 3 days (default), or 7 days, after which the simulation automatically ends.

  Atlas checks for expired simulations in 24-hour intervals so it may take up to an additional day after the expiration date for the simulation to fully resolve.

- Adds a `Maintenance window completed` event to the [Project Activity Feed](https://www.mongodb.com/docs/atlas/tutorial/activity-feed.md#std-label-activity-feed) to confirm when maintenance operations finish.

- Adds support for cross-region [cloud-based initial sync](https://www.mongodb.com/docs/atlas/scale-cluster.md#std-label-cloud-based-initial-sync) between AWS (Amazon Web Services) nodes. This allows Atlas to provision new data nodes from existing nodes in a different AWS (Amazon Web Services) region by leveraging AWS (Amazon Web Services) snapshot capabilities. To further speed up data copy across regions, you can [Enable Faster Cross-Region Initial Sync for AWS Clusters.](https://www.mongodb.com/docs/atlas/cluster-additional-settings.md#std-label-enable_time_based_initial_sync_aws)

- Changes [connection rate limits](https://www.mongodb.com/docs/atlas/reference/atlas-limits.md#std-label-connection-rate-limits) for `M10` and `M20` cluster tiers from 20 to 15 connections per second.

### 22 October 2025 Release

- Adds AWS PrivateLink support for the Prometheus integration.

- Removes the ability to create new Serverless instances in Atlas. To learn more, see [Migrate Programmatic Tools to Flex Clusters.](https://www.mongodb.com/docs/atlas/flex-migration.md#std-label-flex-migration)

### 27 August 2025 Release

- Introduces Intelligent Workload Management (IWM), a dynamic resource manager in Atlas. IWM (Intelligent Workload Management) enables real-time workload monitoring and automated safeguards to maintain high availability under load. Write-blocking, now active for eligible clusters, blocks user writes when disk space is nearly full to prevent node crashes and maintain read availability. To learn more, see [Write-Blocking](https://www.mongodb.com/docs/atlas/intelligent-workload-management.md#std-label-iwm-always-on-protections). If you enable auto-scaling, your cluster has the opportunity to scale up before write-blocking behavior activates.

- Applies [connection rate limits](https://www.mongodb.com/docs/atlas/reference/atlas-limits.md#std-label-connection-limits) to `M10` and `M20` cluster tiers to protect cluster availability. These limits restrict the number of new connections each node processes to 20 connections per second. Connections exceeding these limits are queued, and if the period of overload is sustained, some connections are dropped.

### 6 August 2025 Release

- Adds a total namespaces count to the Catalog cluster metric that displays the total number of collections and indexes across all non-system databases, and adds a new [default alert](https://www.mongodb.com/docs/atlas/configure-alerts.md#std-label-default-alert-settings) that warns users when [`Total Namespaces is`](https://www.mongodb.com/docs/atlas/reference/alert-conditions.md#mongodb-alert-Total-Namespaces-is) over 10,000.

- Makes the ability to [send resource tags to Prometheus](https://www.mongodb.com/docs/atlas/tutorial/prometheus-integration.md#std-label-prometheus-integration) an opt-in feature.

### 16 July 2025 Release

- Makes the ability to [send resource tags to Datadog](https://www.mongodb.com/docs/atlas/tutorial/datadog-integration.md#std-label-datadog-tags) an opt-in feature.

### 4 June 2025 Release

- Adds line items detailing [support subscription charges](https://www.mongodb.com/docs/atlas/billing/subscriptions.md#std-label-view-subscription-charges), per project simplifying cost visualization for customers with multiple projects and reducing manual effort.

### 7 May 2025 Release

- Adds shareable URL support for the [Query Profiler](https://www.mongodb.com/docs/atlas/tutorial/query-profiler.md#std-label-query-profiler), enabling copying and pasting Query Profiler URLs for an easier workflow when working with slow logs.

- Implements General UX fixes and improvements to Query Profiler, including:

  - Increased log retention from five to seven days.

  - Improved available filter selections.

### 23 April 2025 Release

- Adds a preview of a redesigned navigation experience in Atlas. The redesigned navigation provides a composable and scalable Atlas UI structure, improves the self-discovery of Atlas services, and offers clear navigation across services and resources.

- Improves [cluster auto-scaling](https://www.mongodb.com/docs/atlas/cluster-autoscaling.md#std-label-cluster-autoscaling) and elasticity for `M10` and `M20` clusters, responding to resource demands up to five times faster. Optimizes workload performance and availability, potentially lowering costs.

- Allows you to set protected hours for your project, during which Atlas avoids performing standard updates to the clusters. To learn more, see [Configure Your Maintenance Management Settings.](https://www.mongodb.com/docs/atlas/tutorial/configure-maintenance-window-settings.md#std-label-maintenance-window-protected-hours)

- Introduces [Atlas resource policies](https://www.mongodb.com/docs/atlas/atlas-resource-policies.md#std-label-atlas-resource-policies-overview) in public preview. Atlas resource policies define configuration standards for MongoDB clusters across your organization, with options to limit cloud providers, regions, and wildcard IPs.

### 8 January 2025 Release

- Adds the [`Project Database Access Admin`](https://www.mongodb.com/docs/atlas/reference/user-roles.md#mongodb-authrole-Project-Database-Access-Admin), [`Project Backup Manager`](https://www.mongodb.com/docs/atlas/reference/user-roles.md#mongodb-authrole-Project-Backup-Manager), and [`Project Observability Viewer`](https://www.mongodb.com/docs/atlas/reference/user-roles.md#mongodb-authrole-Project-Observability-Viewer) roles that allow for more granular access within Atlas projects.

**Important:**

Atlas began replacing the public IPv4 addresses of dedicated clusters deployed in AWS starting January 21, 2025. If you use standard connection strings (`mongodb://`) and have hardcoded IPs, you must update your firewall or security group configurations to allow the new addresses.

This change affects only public IP access. [VPC peering](https://www.mongodb.com/docs/atlas/atlas-stream-processing/manage-vpc-peering-connections.md#std-label-atlas-sp-manage-vpc-peering) and [Private Endpoints](https://www.mongodb.com/docs/atlas/data-federation/admin/manage-private-endpoint.md#std-label-manage-private-endpoint) are not impacted, as they rely on private networking and not public IPs. The change will be applied in a rolling manner with no downtime, and Atlas will provide guidance before updates take effect.

If you are using SRV-based connection strings (`mongodb+srv://`), no changes are required as DNS will resolve the new IPs automatically.
