Google released the February 2023 product reviews update on February 21, 2023 at about 5 p.m. ET and marked it complete on the Search Status Dashboard on March 7, 2023, after 14 days. It was the sixth release of the product reviews system, following updates in April 2021, December 2021, March 2022, July 2022 and September 2022, as Search Engine Land documented.
The headline change was language coverage. Every previous product reviews update applied to English only; this one applied globally in 11 languages: English, Spanish, German, French, Italian, Vietnamese, Indonesian, Russian, Dutch, Portuguese and Polish. Google Search Central's announcement said the update "applies to these languages globally", listing all 11.
It also opens the Search Status Dashboard era of this log: from this update onward, rollout start and end times come from Google's public dashboard history rather than scattered announcements. And it was the last update to carry the product reviews name, because the April 2023 reviews update renamed the system and broadened it to reviews of anything reviewable.
