   * The Log Analytics agent and Azure Monitor Agent are allowed to use up to 60% of the CPU during their install/upgrade/uninstall operations on Red Hat Linux, CentOS, and other enterprise Linux variants. The limit is higher for this combination of extensions and operating systems to accommodate the performance impact of [SELinux](https://www.redhat.com/en/topics/linux/what-is-selinux) on these systems.

+### New features
+
+- `azcmagent connect` usability improvements:
+  - The `--subscription-id (-s)` parameter now accepts friendly names in addition to subscription IDs
+  - Automatic registration of any missing resource providers for first-time users (additional user permissions required to register resource providers)
+  - A progress bar now appears while the resource is being created and connected
+  - The onboarding script now supports both the yum and dnf package managers on RPM-based Linux systems
+- You can now restrict which URLs can be used to download machine configuration (formerly Azure Policy guest configuration) packages by setting the `allowedGuestConfigPkgUrls` tag on the server resource and providing a comma-separated list of URL patterns to allow.
+
+### Fixed
+
+- Extension installation failures are now reported to Azure more reliably to prevent extensions from being stuck in the "creating" state
+- Metadata for Google Cloud Platform virtual machines can now be retrieved when the agent is configured to use a proxy server
+- Improved network connection retry logic and error handling
+- Linux only: resolves local escalation of privilege vulnerability [CVE-2022-38007](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-38007)
