Simplified client operations for cloud users: Network settings are no longer mandatory for stateless client mounts or when creating WEKA containers. By default, the system attempts to allocate and use a network device when possible.
For UDP mounts, the explicit -o net=udp option is now required.
Network device specification remains mandatory for SCMC deployments.
Maximum processes increased: The maximum number of backend processes, drive processes, management processes, and total processes have all been increased.
Enhanced security: Strengthened cipher support has been implemented for the WEKA HTTP server.
High Availability (HA): Improved link recovery for large HA clusters.
Client driver enhancements: Updates include:
Reduced load average per frontend.
Increased resilience to network fluctuations and container state changes.
Reduced operational wait times.
Improved backward compatibility.
Enhanced NFS statistics: NFS statistics, previously available on a per-client basis, are now accessible per client per export using the CLI.
Expanded metrics: New metrics for monitoring include:
Response codes.
Read/write counters.
Response times (e.g., average time to first and last byte).
Filesystem operations, including resultant read/write bytes and operation counts with associated response codes.
Improved configuration handling: The "Share [+ Create]" button is now disabled during SMB cluster directory service joining and configuration completion. This ensures functionality before additional actions can be performed.
Extended client support: WEKA client support now includes:
Proxmox 8.1.4 and 8.2.

4.4.2.113
This release introduces security and usability enhancements and new features for SMB-W parity with legacy SMB. Key updates include support for tagged VLANs for customers using network segregation in tenancy models, enhanced role-based access controls for the Kubernetes CSI driver, and automatic client removal timeouts for short-lifecycle clients. Additionally, users can choose their preferred numeric display format (Base-2 or Base-10) in the GUI.
New CSI operator role: A new csi operator role has been introduced, allowing essential tasks with elevated privileges, such as creating filesystems, monitoring cluster status, and managing snapshots. This role provides necessary functionality without granting full ClusterAdmin or OrgAdmin access.
Tagged VLAN IDs: Tagged VLANs enable per-NIC VLAN assignments for containers, allowing advanced network configurations and integration with diverse setups when mounting filesystems.
Updated status values: WEKA S3 clusters now use updated status labels:
Down is now Offline.
Not Ready is now Faulty.
Ready is now Online.
A new status, Saturated, indicates temporary service disruption caused by an overload of S3 requests. The Faulty status reflects more severe issues than Saturated.
Improved Active Directory integration: The SMB-W service now supports the --server and --create-computer options for joining SMB-W clusters to Active Directory. These updates also facilitate the migration of legacy SMB configurations, ensuring improved compatibility.
Dynamic client lifecycle support: The weka local setup container command now supports --auto-remove-timeout and --client options, streamlining management for short-lifecycle clients.
Customizable numeric display format: A new GUI option allows users to switch between Base-2 (binary) and Base-10 (decimal) numeric display formats. This provides flexibility in viewing capacities and metrics based on user preferences.
New security APIs: Added REST APIs corresponding to the CIDR-based security policy CLI commands introduced in a previous release.
AWS solutions: Introduced a new AWS solutions section, starting with the Integrate SageMaker HyperPod with WEKA using Slurm guide, which covers architecture and deployment workflow for the integration.
Synchronous Snap: Updated the note to specify that only snapshots uploaded from version 4.3 or later can be downloaded using Synchronous Snap. Previously, the note indicated version 4.0 or later.
4.4.1
This release includes a variety of optimizations to benefit customers operating the WEKA Data Platform at scale.
Improvements
Added weka driver commands: Introduced a set of tools for managing drivers, including capabilities for building and signing drivers, import/export functionality for easier administration, and readiness checks to enhance reliability.
Added snapshot size estimations: Snapshot listings now include size estimations, helping customers understand the capacity occupied by chains of snapshots.
Expanded CIDR-based security policies: In the previous release, CIDR-based security policies were introduced to manage access to WEKA clusters by client IP address ranges, enhancing security and simplifying administration for Organizations users. This release extends the security policy functionality to include filesystems.
Added support for HashiCorp Vault AppRole: WEKA now supports HashiCorp Vault's security best practice, AppRole. Unlike the traditional token system with long-lived tokens requiring manual refresh, AppRole uses a RoleID and SecretID to retrieve short-lived tokens for accessing secrets. This enhances the security posture of the KMS configuration in WEKA.
Added support for unique KMS Configuration per filesystem: WEKA now supports a separate KMS configuration for each filesystem, replacing the previous cluster-wide configuration. This feature enables customers to use distinct key hierarchies for individual filesystems.
NFS-W enhancements
Added Support for NFSv4 ACLs in NFS-W: NFS-W now supports NFSv4 access control lists (ACLs) up to the extended attribute limit of inodes on WEKA clusters. The mode of NFS-related ACLs can be viewed with weka nfs global-config show and enabled through weka nfs global-config set --acl on.
S3 enhancements
Enhanced WEKA S3 response statistics: WEKA S3 response statistics now include byte counts, response code distribution per minute, and the average time to first byte, providing deeper insights into S3 performance.
Added WEKA S3 events for problem and recovery scenarios: New events for WEKA S3 now cover problem and recovery scenarios. The S3ContainerStatusSaturatedEvent indicates that capacity thresholds have been met, while the S3ContainerStatusOnlineEvent signals that the container is online and available.
Updated weka s3 cluster -v command output: The weka s3 cluster -v command now includes SLB request output, highlighting the limits used in the new saturation event for improved visibility.
SMB-W enhancements
Enhanced UI for ACLs: Access control models that were previously available only via CLI are now visible and selectable in the UI during the Add SMB Share process.
Added direct object store sync option in add SMB share: The new obs-direct option in the add smb share command allows customers to bypass time-based file retention policies. When files are created or written to a share with this option enabled, they are prioritized for immediate release.
Additional enhancements
Graceful behavior by default for weka local commands: The weka local stop, restart, and apply resources commands now execute gracefully by default, eliminating the need to use the --graceful argument.
GCP update: Added gVNIC support in DPDK mode, in addition to UDP.
Added support for GCP regions asia-southeast2 and europe-central2 in Terraform configuration.
CDM Local version 1.2 updates: Supports automated Terraform deployment, removes the Windows installation package, updates the launch process, and enhances information gathering options.
WEKA CSI Plugin version 2.5.0 updates: Provides NFS transport support designed for non-performance-critical scenarios or environments where installing the WEKA client is not feasible.
Certified object stores: Added Dell PowerScale S3 (version 9.8.0.0 and higher) to the certified object stores.
4.4.0
This release includes a variety of optimizations to benefit customers operating the WEKA Data Platform at scale.
Improvements
weka stats performance enhancements reduce the latency of metric reporting, especially on large clusters.
To limit access to POSIX filesystems in Organizations, define access lists by network and role by weka security policy hierarchy. Attach, detach, and test policies by weka org security policy.
Customers using clients with multiple clusters can now store profile tokens and reference them by name for convenience. The profile token location is $HOME/.weka/auth-token-<profile>.json, and invocation by the new profile parameter, such as weka user login [—-profile <profile-name>].
SMB-W enhancements
WEKA now supports configuring shares with user permissions in advance of validating the user with directory services
Commands share add and share update now support allow-guest-access.
Added the ACLs feature to enable or disable Windows Access-Control Lists for the share, offering options for POSIX, Windows, or Hybrid (default: POSIX) and allowing interoperability by prioritizing the most recent permission based on timestamps.
S3 enhancement
Introduced an updated health-check URL, /wekas3api/health/ready, for load balancers to use in assessing the health of S3 servers, improving monitoring and load balancing capabilities.
Additional enhancements
WEKA client support is extended to: Debian 10, Rocky 8.6, Rocky 8.7, Rocky 8.8, Oracle Linux 9, and SLES 15 SP5.
Added a verification step for LLQ and WC in the upgrade workflow. To ensure proper LLQ functionality after upgrades, verify that Write Combining (WC) is enabled in the igb_uio driver.
Added a CLI reference guide, which is generated from the output of running the weka command with the help option. It provides detailed descriptions of available commands, arguments, and options.
