# Release Notes Replica's release notes contain a high-level overview of features and improvements in each version of Replica. These notes are provided to help users stay informed about the latest platform changes. The features in the latest version automatically become available to users as soon as the release is made available. {% updates format="full" %} {% update date="2026-01-29" %} ## Replica 4.4.0 #### Highlights * New Enclave Storage Type: choose Isolated or Synchronous storage for each Enclave to support strict separation or shared, reusable workflows. * Expanded security monitoring coverage * Faster, steadier provisioning at scale with standardized images, improved image transfer paths, added capacity, safer upgrades, and runtime hardening. * Improved networking for Windows-based VEs, including the ability to “hot swap” an egress. #### What shipped **Enclaves & storage** * Added Enclave “Storage Type” setting with two options: * Isolated — self-contained storage for strict separation. Content is only accessible by assignee(s) and must be manually shared with other users or enclaves. * Synchronous — persistent sharable storage. Content is accessible in real time by any user or environment with access. * Enclaves are now “assignable”. * Note: customers asked for more granular access controls (e.g., read-only vs read/write and group-based access). Those controls are not part of this release; v4.4 establishes the storage behavior selection. **Identity & access controls** * Enforced re-authentication before sensitive actions (“Force Reauth”). * Tighter isolate-route permission structure (least privilege). * 2FA styling/flow consistency improvements. **Secrets & certificates** * Security enhancements to internal vault **Observability & logging** * Improved security monitoring coverage * Logging menu item fixed for Monitor user role. **Provisioning, scale & reliability** * Standardized Windows and Linux images (4.4.x). * Improved Malware environment image transfer and backups. * Added capacity and tuned scaling for key services. * Safer upgrade behavior. * Runtime hardening improvements. * FlareVM available for Malware environments (analysis image). **Analyst/admin experience + networking** * Updated Guest Portal experience. * New Troubleshooter portal for pre-flight checks and faster diagnosis. * Router messaging improvements; clearer zones/time lifecycle states during setup and management. * Egress tunneling enforcement moved from per-VM clients to cluster routers; VM environment egress routing aligns with container environments for a more consistent experience. * VE Toolbox is now “relocate-able”. {% endupdate %} {% update date="2025-10-13" %} ## Replica 4.3.0 The 4.3 release of Replica was focused on completing all of the necessary work to enable Replica to enter the SOC2 – Type 2 audit period. We are pleased to announce that this audit began earlier this month as we finished wrapping up the features of this release that were not associated with Security and Compliance efforts. The balance of the development work this cycle pivoted to elements of the User Interface and User Experience, Administrative workflows as well as the usual improvements and bug fixes. Here are the highlights of the Replica 4.3 release: #### Security and Compliance * Replica has entered the mandatory 90-day audit period before officially becoming SOC2 – Type 2 certified. This was a wide-ranging effort and touched every part of the product. We will update all customers as soon as the audit period is complete and the certification is official. #### User Interface/User Experience * New User centric UI that consolidates all of the critical components of Replica into a single pane of glass – Virtual Environments, Enclaves, Egress and the newly introduced “Quick Create”. * Enhanced Notifications that are easier to read * Updated Animations #### Platform * Improved Troubleshooter utility – more robust testing to ensure that your host system is best configured to deliver maximum performance of Replica. * VE Linux images have been upgraded to Ubuntu 25.10 #### Administration * List views are now exportable to CSV. This includes both the list view of Virtual Environment and the list view of Users * Last Login information is now included in Users * Actions tab is pinned to the right side of the list views #### Improvements * Enhanced fine grain auditing for API events * Added log monitor for Elastic Search – will improve health, hygiene and resiliency #### Bug Fixes * There was a known bug in the Isolate route (end point) that was remediated with this fix * Pulse audio issue was resolved in DCV for this release {% endupdate %} {% update date="2025-07-21" %} ## Replica 4.2.0 Replica 4.2.1 is the latest release of the Replica platform. The flagship feature of this release is the debut of File Request Enclaves – a seamless way to invite third parties to collaborate with you safely and securely within Replica. As is customary for us, this is the first in a series of new capabilities designed to empower our users to extend the perimeter of what is traditionally understood as the boundary of trusted work. We are excited to bring this release to you and welcome feedback on this release. Please read below for highlights from this release: #### Butler * **File Request Enclaves:** This feature allows users to convert an existing Enclave into a File Request Enclave. File requests can be sent to any third party email, and files can be transferred safely and securely into this Enclave (subject to Butler file transfer limits). Once the Enclave is converted, it can no longer be mounted to a traditional VE, but instead a unique, “locked down” VE can be created to view and manipulate the files from within the safety and security of Replica. You can learn more about this feature on our website – [www.replicacyber.com](http://www.replicacyber.com) * **Permissions:** Fine-grained Butler permissions for both files and Enclaves can now be scoped at the user or group level. #### Platform * **Image Catalog:** Improvements to the Image Catalog include installed applications and descriptions. This applies to both images presented when creating a VE and the Administrator view of the catalog. * **Egress:** Customers now have the ability to configure egresses that cannot be changed. Geared toward supporting the creation and maintenance of online personas, these egresses are fixed at creation time, which prevents accidental slippage in tradecraft. * **User Management:** Self Service password reset functionality has been improved for both ease of use and delivery of the password reset email to users’ inboxes. Note: Emails will now come from . * **Group Management:** Group hierarchy is now clearly displayed in the Group Management section of Replica. This is part of a larger focus on making User and Group Management more streamlined and effective for our customers. #### Malware * **Management:** We are implementing VE caps on deployed Zones within Replica to avoid overprovisioning Malware resources. We will continue to improve and iterate on Zone management and encourage customers who have Malware Zones deployed to continue to raise feature requests in this space. #### Software-defined telephony * **Call Forwarding:** Users can clear the call forwarding field to restore the number to SMS-only. #### Virtual environments * **Bulk Create:** Users with the appropriate role can now create multiple VEs and Temporary User accounts with the click of a button. Use cases include: delivering online training, collaborating with teammates or workshops. * **Greyscale:** Based on user feedback, we have implemented the ability to view sensitive content in a VE in either Greyscale or Black/White. * **UI Improvements:** Several improvements and optimizations were implemented on the “Environments” page in Replica. These include (but are not limited to): additional information provided on the VE card, rendering of certain UI elements, and overall performance of the page. #### Mobile telephony * **Fix:** More resilient and reliable deployment method for the Mobile Phone to a VE. #### Updates * Normal security fixes and updates to the platform to keep you and your work safe while leveraging the latest technologies available to further your mission. Updates include (but are not limited to): upgrading Kubernetes, moving some database elements from Postgres to RDS, Updating and Back-up workflow improvements and token management improvements. {% endupdate %} {% update date="2025-05-28" %} ## Replica 4.1.0 We are pleased to announce our latest update to Replica – Replica 4.1 Building on the work done in the 4.0 release, Replica 4.1 advances the platform’s redesigned user experience and advanced architecture.
