Dependencies
| Agent |
This release requires agent version 9.5.0.51. After upgrading from an earlier VSA version, you must update your Windows, macOS, and Linux agents using the automatic or manual update process from the agent module. Note: this version cannot be installed to some End-of-Life macOS versions. Please reference the "Updates to macOS and Linux agent supported versions" section below for further details. |
| Live Connect Application | When starting a Live Connect or Remote Control session for the first time after installing this release, you will be prompted with a link to download the latest Live Connect build. You must complete the installation before proceeding with the session. |
| Software Management |
This release includes updates to the Software Management client code. Each managed machine will download 120 MB of file updates during the first patch scan or deployment cycle after installing the VSA update. The files will be sourced from the VSA server or a peer endpoint machine on the local network that already has the files. Recommendations to mitigate the impact on network bandwidth:

Our policy is to provide support for the current GA release, one prior Feature Release, and any interim Maintenance Releases. After the 9.5.26 GA date stated in the release schedule, the minimum supported version will be the 9.5.25 Feature Release.
