# What's New in This Release

## MSL Release 12.1

- MSL Release 12.1 provides support for CloudLink in the MSL standard installation.

- Remote Management can Configure IPv6 address from server manager.

## MSL Release 12.0

- MSL Release 12.0 now supports TLS 1.3 along with TLS 1.2.
  Note: TLS 1.1 and TLS 1.0 are no longer regarded as secure and not supported by MSL 12.0.

## MSL Release 11.0

MSL Release 11.0 provides the following new features:

- The server manager "Shutdown or Reconfigure" panel has been renamed to "Shutdown or reboot". The Reconfigure option in that panel has been removed.
- The server manager "Web Server" panel has a field for entering Subject Alternate Names (SANs) for the server, when generating a Certificate Signing Request.
- The server manager "Hostnames and addresses" panel does not comprise invalid host names section, and the "Review configuration" panel does not comprise server names section such as mail.domain, ftp.domain, www.domain, and so on.
- When running MSL on EX platform, the option to restore from removable media or another running server are not available.
- MiCollab and MBG supports licensing through the Licenses & Services Application (SLS License Server). The Mitel Licenses & Services Application manages the software licensing and entitlement of the Software Assurance Program. After you obtain a ServiceLink ID or Serial ID from the SLS License Server, the SLS uses your ServiceLink ID to provide you with access to licenses, software releases, and upgrades.
- To activate an SLS Serial ID the following connections must be allowed through any firewalls.
  - FQDN: sync.sls.mitel.com, Current IP: 18.200.183.29 Port: 22 Protocol: SSH
  - Customer must verify current IP before creating firewall rules as the IP address may be subject to occasional change.
- Supported Upgrade Methods: MSL 11.0 is available only as a 64-bit distribution. Migration from a 32-bit to a 64-bit system requires a fresh software installation, either manually or using the new Remote Fresh Install blade.
  - The application blade software is no longer downloaded from the AMC but the AMC still provides software licensing. MSL 11.0 uses the Mitel Software Download Center, supported by a global content distribution network to increase speed and reliability of downloads.

    The following outbound connections must be allowed through your firewall:

    License entitlement:

    - register.mitel-amc.com 216.191.234.91 port 22
    - sync.mitel-amc.com 216.191.234.91 port 22

    Access token for content delivery network:

    - swdlgw.mitel.com 99.81.17.20 port 443 (occurs during available blade software list update)

    Content delivery network for blade software download:

    - swdl.mitel.com port 443 (IP address based on location)
      Note: For the Akamai FQDN swdl.mitel.com, the static IP address ranges cannot be guaranteed by the Content Delivery Network. Thus, any firewall rules should allow the FQDN.
    - The following able outlines the supported upgrade methods:

  Upgrading from... | Upgrading To | Supported Upgrade Methods
  --- | --- | ---
  10.x releases (32-bit or 64-bit) | 11.0 (64-bit) | Fresh Install from CD/DVD/USB Remote Fresh Install
  9.x releases (32-bit) | 11.0 (64-bit) | Fresh Install from CD/DVD/USB

- Cloud Platform Support:

  The following features are supported on the Azure platform:

  - Hostname: The default hostname will be the lower case VM name. Any invalid hostname characters, such as periods or underscores, will be translated to hyphens
  - Networking: MSL supports auto-provisioning of network elements, such as NICs, public/private IP addresses, gateways, routing and DNS
  - On every reboot, which includes following a restore operation, the VM networking is analyzed and auto-provisioned if any changes are detected

  - Supports auto-registration of the VM hostname in a private DNS zone linked to the virtual network of the primary (first) NIC. Only the primary (first) private IP linked to the NIC is registered. So, if the configuration console changes the hostname, the private DNS entry will be updated accordingly when the reboot occurs.

  - Supports custom data when creating a VM.
    Note: Refer to Cloud Platform Support in the Mitel Standard Linux Installation and Maintenance Guide for more information.
- Backup and Restore using AWS S3 buckets:
  Now, backups to the network file server and restoration of the backed up files stored in the network File Server can be processed using HTTPS through Amazon Web Services Simple Storage Service (that is, AWS S3).
  Note:

  Refer to Backup and Restore topics for more details.
