Breaking changes

edit

Breaking changes can prevent your application from optimal operation and performance. Before you upgrade, review the breaking changes, then mitigate the impact to your application.

Fleet Server and Elastic Agent now reject certificates signed with SHA-1

Details
With the upgrade to Go 1.18, Fleet Server now rejects certificates signed with SHA-1. For more information, refer to the Go 1.18 release notes.

Impact
Do not sign certificates with SHA-1. If you are using old certificates signed with SHA-1, update them now.

Known issues

edit
Installation of Elastic Agent on MacOS Ventura may fail if Full Disk Access has not been granted to the installer

Details
This issue occurs on MacOS Ventura when Full Disk Access is not granted to the application that runs the installation command. This could be either a Terminal or any custom package that a user has built to distribute Elastic Agent.

Impact
Elastic Agent will fail to install and produce "Error: failed to fix permissions: chown elastic-agent.app: operation not permitted" message. Ensure that the application used to install Elastic Agent (for example, the Terminal or custom package) has Full Disk Access before running sudo ./elastic-agent install.
