What Changed
Google updates Extended Stable with 72 listed security fixes, including four rated Critical. Its patch set and version differ from the regular Stable release.
What To Validate Now
- Inventory. Record browser channel, operating system, installed version, update policy, extensions and responsible device owner.
- Establish applicability. Confirm Extended Stable selection and Windows or macOS. This advisory does not provide an Extended Stable target for Linux, Android or ChromeOS.
- Remediate. Apply the official 156.0.8078.100 package through the supported enterprise update channel and enforce the approved relaunch schedule.
- Validate. Confirm both channel and running version; test enterprise login, important applications, policy enforcement and required extensions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Retain rollout and exception evidence while Google stages availability. Do not switch release channels or treat a regular Stable package as the same maintenance action without reviewing support policy.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
