+ - v10.5 introduces Property System Architecture schema migration. See the [Important Upgrade Notes](https://docs.mattermost.com/upgrade/important-upgrade-notes.html) for details.

Plugins are deployed manually when an administrator or some deployment automation copies the contents of a plugin bundle into the server's working directory. If a manual or automated deployment workflow is still required, administrators can instead prepackage the plugin bundles. See more details in `this forum post <https://forum.mattermost.com/t/deprecation-notice-manual-plugin-deployment/21192>`__.
+ - Mattermost has stopped official Mattermost server builds for the Microsoft Windows operating system. Administrators should migrate existing Mattermost server installations to use the official Linux builds.
