20260831.01_p0 Release
Installed latest packages from upstream dependencies.
Installed latest packages from upstream dependencies.
The terminal and file browser are now more responsive when working in a Cloud Storage bucket that is mounted through the file browser. Frequent background checks for non-existent files are now cached instead of repeatedly querying Cloud Storage, which previously could make actions such as listing files or running terminal commands take several seconds.
Cloud Storage buckets that you mount through the file browser are now automatically re-mounted after the instance is restarted or is stopped and started. Previously the mounted folder could be left behind as an empty, unusable directory that had to be manually removed and re-mounted.
The obsolete google-cloud-sdk transitional package is no longer installed. The Google Cloud CLI itself is unchanged; it was already provided by the google-cloud-cli package.

20260830-2154-rc1 Release
Installed latest packages from upstream dependencies.
Fixed an issue where a notebook's cells and their outputs could be unexpectedly erased. The automatic reload of an open notebook (which keeps it in sync with changes made to its file on disk) is now restricted to run only while the Gemini CLI is in use, so notebooks are no longer overwritten at other times.

Agent Platform Workbench instances internal agents now honor custom CA certificates installed on the host OS (e.g. via a custom VM image), fixing TLS certificate verification failures when Google API traffic is routed through a customer-managed proxy.
