macOS 10.15.6 available via software update or download links below.
(Also below are Downloads of Security Update 2020-004 for 10.14.6/10.13.6.)
Here's details from the macOS Catalina 10.15.6 release notes.
"macOS Catalina 10.15.6 introduces local news in your Today feed in Apple News and improves the security and reliability of your Mac.

    Apple News
  • Local news in your Today feed provides extensive coverage of San Francisco, the Bay Area, Los Angeles, Houston, and New York City.
  • More stories available from local news providers with a subscription to Apple News+.
  • Your daily newsletter from Apple News can now be personalized with stories that reflect your interests.

This update also includes bug fixes and other improvements.

  • Adds a new option to optimize video streaming on HDR-compatible Mac notebooks for improved battery life.
  • Fixes an issue where the computer name may change after installing a software update.
  • Resolves an issue where certain USB mouse and trackpads may lose connection.

Enterprise content:

  • When using the built-in keyboard with a non-U.S. keyboard layout on some Mac models, passwords with certain characters are no longer rejected at the Mac login window.
  • Allows command-line tools that don't use CFNetwork, such as curl(1), to continue connecting to TLS servers that use certificates issued by the recently expired AddTrust External CA Root.
  • Major new releases of macOS can be hidden when using the softwareupdate(8) command with the --ignore flag, if the Mac is enrolled in Apple School Manager, Apple Business Manager, or a user-approved MDM.
    (This change also affects macOS Mojave & High Sierra after installing Security Update 2020-004.)

    Some features may not be available for all regions, or on all Apple devices. For detailed information about the security content of this update, please visit:"

  • Also released are Security Update 2020-004 Mojave, & Security Update 2020-004 High Sierra (downloads below). Here's the article on security fixes in macOS 10.15.6 and Security Updates 2020-004 for 10.14.6/10.13.6. (macOS 10.15.6 includes Safari 13.1.2, also available for macOS 10.14.6 & 10.13.6.)

    FYI: If you use Nvidia's web graphics drivers for 10.13.6, the Security Update's new build number requires a driver update. (See below for July 16th, 2020 driver update download.)
