Filter version v4 is available and set as the default for the Latest alias.

Filter version v4 is available and set as the default for the Latest alias. Filter version v3 is promoted to the Stable alias in all supported regions except the following:

• In asia-northeast3, v1 remains the Stable version.
• In australia-southeast2, v3 becomes the Stable version on September 25, 2026.

If your templates use the Stable alias, they automatically upgrade to v3 when v3 becomes Stable in that region.

Filter versions v1 (except in asia-northeast3, and starting September 25, 2026 in australia-southeast2) and v2 transition to Legacy status and retire on December 17, 2026. If your templates are explicitly configured with v1 or v2 in regions where those versions are in Legacy status, you must migrate them to v3 or the Stable alias before December 17, 2026.
