For the complete summary of changes and release binaries check out the [release notes](https://github.com/fleetdm/fleet/releases/tag/3.11.0) on GitHub.
## Improved performance
Fleet is utilized by organizations with up to hundreds of thousands of endpoints. As a result, we’re constantly looking for areas to improve performance. Changes introduced in Fleet 3.11.0 reduce the MySQL CPU usage by ~ 33%.
These performance improvements are the result of batching the updates of the last time a host has connected to the server. For more details on these changes, check out the [pull request](https://github.com/fleetdm/fleet/pull/633) from our Cofounder, [Zach Wasserman](https://medium.com/u/b0291119b263?source=post_page-----25d5a1efe19c--------------------------------).
## Software inventory
Keeping tabs on what software is installed on your hosts can be the first step in managing vulnerable software. We’ve exposed a list of installed software on each host’s respective Host details page.
This feature is flagged off by default for now. Enable software inventory for your Fleet by setting the environment variable `FLEET_BETA_SOFTWARE_INVENTORY=1`. For additional information on feature flags in Fleet, see the [Feature flag section](https://fleetdm.com/docs/deploying/configuration#feature-flags) of the documentation.
To see the osquery queries that power software inventory, check out Fleet’s [Standard query library](https://fleetdm.com/queries). The “Get installed macOS software,” “Get installed Linux software,” “Get installed Windows software,” and “Get installed FreeBSD software” queries are utilized depending on a host’s operating system.
## Running common queries
When investigating a specific host, it’s important to be able to quickly gather the data you want. To support this, running common queries against a specific host just got more convenient. Fleet 3.11.0 introduces the ability to select a saved query direct from a host’s respective Host details page.
Select the “Query” button to filter through a complete list of your saved queries.
