IMPORTANT

Beginning with HPE Morpheus Enterprise Software 8.1.0, the embedded search service changes from Elasticsearch to OpenSearch. This change only affects HPE Morpheus Enterprise Software as HPE Morpheus VM Essentials already uses OpenSearch. HPE continues to support both ElasticSearch and OpenSearch for external clusters. Consult [this section](https://support.hpe.com/hpesc/docDisplay?docId=sd00007510en_us&page=GUID-ECFD4939-8F53-44BB-B8D7-094E28DFAB7C.html) of the user manual for upgrade, migration, and configuration details.

IMPORTANT

HPE Morpheus Enterprise Software version v8.1.0 does not support rolling upgrades. Consult [non-rolling upgrade documentation](https://support.hpe.com/hpesc/docDisplay?docId=sd00007510en_us&page=GUID-5205CDAA-81D9-412F-9DF2-6A2A6CA9D1EC.html) for upgrade process steps.

IMPORTANT

After upgrading to v8.1.0, it is required to also upgrade HVM Host agents as well. To upgrade HVM Host agents, navigate to the detail page for each HVM Host, expand the ACTIONS menu, and click "Upgrade Agent." This process must be undertaken on all HVM Hosts. Alternatively, you may select "Download Agent Script" to download a shell script to handle the upgrade. Connect to the HVM Host over a terminal session and run the downloaded script. The scripts are unique to each HVM Host so you must download all required scripts and run the correct script against the correct HVM Host.

# New Features

Alletra MP Plugin
:   - For complete update details, see the [Alletra MP plugin release notes](https://support.hpe.com/hpesc/public/docDisplay?docId=sd00007519en_us)

Appliance
:   - There is now a single binary installer for both HPE Morpheus Enterprise Software and HPE Morpheus VM Essentials Software. Feature access is controlled solely by licensing. Previously, HPE Morpheus Enterprise and HPE Morpheus VM Essentials had separate binary packages
    - For newly-installed environments without a paid license configured, the evaluation period has been extended from 30 to 60 days

Aruba CX Plugin
:   - Version 1.9.0 of the plugin has been released
    - The serial numbers and health status for each switch are now shown within the network tab of the integration detail
    - Other internal improvements

Aruba CX DSS Plugin
:   - Version 1.5.0 of the plugin has been released
    - Users may now specify a Policy Distribution Target (PDT) when creating a DSS port group

HVM
:   - Added vCPU placement (NUMA and L3 boundaries) control for HVM clusters

Library
:   - HPE Morpheus VM Essentials now includes a default library of example images that can be provisioned to HVM Clusters or integrated VMware Clouds right out of the box

Security
:   - Updates to internal dependency libraries to close potential security vulnerabilities

Tenants
:   - Storage volume detail pages now show the volume UUID

# Fixes

API & CLI
:   - Datastores created via API now have the Tenant permissions given in the request payload
    - Improved the efficiency of making calls to list instances (/api/instances) which, in some environments, could be slow to respond

Bare Metal
:   - Added various fixes and hardening improvements for the HPE Bare Metal Plugin (BMaaS). See the updated integration guide for complete information on plugin use and capabilities

Google Cloud
:   - When adding Security Groups, the dropdown menu now shows only Security Groups belonging to GCP rather than all Security Groups

HVM
:   - Fixed an issue that caused GFS2 to change to a read-only state when rebooting the HVM Host

NSX
:   - Adding NSX Firewall Rules from the Network section of an Instance detail now properly shows the special modal for creating NSX Firewall Rules rather than the generic modal for other Firewall Rule types. This is the same expected modal shown when creating NSX Firewall Rules from the integration detail

Terraform
:   - When applying Terraform state or taking other actions involving Terraform (ex. creating Catalog Items from Terraform Blueprints), decimal values ending in ".0" are no longer truncated (ex. 1.0 -> 1)
