"Based on your feedback, today we're announcing some new changes for servicing Windows 7 SP1 and Windows 8.1… From October 2016 onwards, Windows will release a single Monthly Rollup that addresses both security issues and reliability issues in a single update. The Monthly Rollup will be published to Windows Update (WU), WSUS, SCCM, and the Microsoft Update Catalog. Each month's rollup will supersede the previous month's rollup, so there will always be only one update required for your Windows PCs to get current. i.e. a Monthly Rollup in October 2016 will include all updates for October, while November 2016 will include October and November updates, and so on. Devices that have this rollup installed from Windows Update or WSUS will utilize express packages, keeping the monthly download size small.
Over time, Windows will also proactively add patches to the Monthly Rollup that have been released in the past. Our goal is eventually to include all of the patches we have shipped in the past since the last baseline, so that the Monthly Rollup becomes fully cumulative and you need only to install the latest single rollup to be up to date. We encourage you to move to the Monthly Rollup model to improve reliability and quality of updating all versions of Windows."
Beginning in October 2016 onwards, don't expect to see individual KB's but instead expect to see the following in the monthly patch release cycle:
Security-Only Update - Collects all of the security patches for that month into a single update
Monthly Rollup - Security updates from previous bullet point; All updates, rollups, patches, and security updates for that month; Proactive addition of previously shipped patches (within 6-8 months the monthly rollup will include all patches back to the last baseline and will be fully cumulative)
.Net Framework Security-Only Update - Contains only security updates
.Net Framework Rollup - .Net Framework Security Updates from Previous Bullet Point; Reliability updates
