Not announced
How we reached this date
The last 8 gaps between Jetpack releases ran 26 to 36 days, typically 30 days. The latest line, 16.3, came out on 6 October 2026.
Counting on from there, and ignoring past gaps that are already shorter than the time that has passed, the most likely day is 6 November 2026, inside a window from 2 November 2026 to 10 November 2026.
The 67% is the share of comparable past releases that landed in a window like this, reduced a little because the sample is small. It is not a promise.

From the plugin's own description
Your WordPress site, now in the conversation Jetpack connects your WordPress site to ChatGPT, Claude, and the other AI agents you already use. Ask in plain language to draft a post, see which pages got the most views, check your backups, or run a security scan, and your agent takes care of it on your site. There’s no MCP server to set up or host. That works because Jetpack plugs your site into WordPress.com’s cloud, the same infrastructure that runs millions of sites. The heavy lifting happens there instead of on your host: backups stored off-site with one-click restores and full site migration, malware scanning, brute force protection, downtime monitoring, site analytics with Jetpack Stats,…

How well has this method worked?
