MachPanel v8.3.25
A Major Release for MSPs, Enterprises, Hosting, and Cloud Service Providers
MachSol has released MachPanel v8.3.25, the latest build of its automation platform for teams running Hyper-V, Exchange, and Microsoft 365 environments across multiple tenants. This release adds Hyper-V cluster snapshot support, over 30 new REST API endpoints, a set of Exchange management improvements, and fixes for several critical security vulnerabilities
If you’re evaluating alternatives to VMware for VPS hosting, this is a build worth looking at.
Here’s what’s actually worth knowing, and how to get the most out of it.
Security fixes you shouldn’t wait on
Starting here because it matters most. This build patches SQL injection, stored cross-site scripting, insecure direct object reference, and an SSO bypass via an alternative login page. It also hardens authentication and authorization controls and updates several third-party components with known CVEs, including Bootstrap, Bootstrap-select, Chart.js, and Vue.js.
Hosting platforms are a real target, and every unpatched vulnerability is exposure you’re carrying. Updating to v8.3.25 applies all of these fixes in one pass, no separate configuration required.

Hyper-V cluster snapshot support: real disaster recovery for clustered VMs
MachPanel now supports snapshots for Hyper-V cluster deployments, not just standalone VMs. Paired with the new cluster-aware VPS import and automatic owner node updates, this closes a real gap for providers running clustered Hyper-V environments. Protecting a VM that can move between nodes used to mean manual console work outside MachPanel. Now it’s handled inside the platform.
For providers building or scaling a Hyper-V based VPS business, an automation and orchestration platform, not manual console work, is what makes multi-tenant hosting sustainable at volume.
Exchange management, tightened across the board
This release doesn’t add one standout Exchange feature so much as it cleans up a long list of things administrators deal with regularly:
- Distribution list membership management rebuilt to handle very large lists, in the 10,000+ member range, without the slow loading that used to come with big DLs
- Broader deadlock prevention across Exchange and AD management
- Full access permissions now update automatically on resource and room mailboxes when the manager changes
- A dedicated custom quota setting for personal archiving
- Mailbox exports now include LegacyExchangeDN
- Primary email addresses update automatically when an AD user’s UPN changes
- New REST API coverage specific to mailboxes, including PATCH support for general and advanced settingsAlongside these, a set of fixes addresses issues admins have likely run into directly: shared mailbox permission handling, public folder mailboxes not being removed after a subscription cancellation, custom quota values not displaying correctly in the mailbox advanced tab, and an export error on the customer side.30+ new REST API endpoints for deeper automation
For teams automating provisioning or integrating MachPanel with billing, CRM, or internal tooling, this build adds REST API coverage for mailbox type changes, calendar permissions, AD authentication, advanced settings, and mailbox add-on reports. More endpoint coverage means fewer workflows that still require manual clicks in the UI, which is the whole point of running an orchestration platform instead of managing Hyper-V, Exchange, and AD by hand across every tenant.
Also in this release
A long list of smaller improvements across VPS and Active Directory management, including:
- VM reinstall, without full re-provisioning
- OS installation via ISO during VM creation, and OS type changes for existing VMs
- Dynamic IP allocation for Linux VMs
- A separate VLANs report for network auditing
- Per-interface firewall reset
- More granular staff, customer, and reseller permissions across AD, Hyper-V, and Exchange
- Enhanced audit logging across Exchange, Hyper-V, and Skype for Business modules
