Microsoft released cumulative update KB 4541335 with non-security improvements and fixes for Windows 10 Versions 1909 and 1903 today. From the KB Article:

Quote
"Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files. As a result, the new features in Windows 10, version 1909 were included in the recent monthly quality update for Windows 10, version 1903 (released October 8, 2019), but are currently in a dormant state. These new features will remain dormant until they are turned on using an enablement package, which is a small, quick-to-install “master switch” that simply activates the Windows 10, version 1909 features.

To reflect this change, the release notes for Windows 10, version 1903 and Windows 10, version 1909 will share an update history page. Each release page will contain a list of addressed issues for both 1903 and 1909 versions. Note that the 1909 version will always contain the fixes for 1903; however, 1903 will not contain the fixes for 1909. This page will provide you with the build numbers for both 1909 and 1903 versions so that it will be easier for support to assist you if you encounter issues.

For more details about the enablement package and how to get the feature update, see the Windows 10, version 1909 delivery options blog."

In addition, Microsoft made the change below and documented in the Windows message center:

"Timing for upcoming Windows optional C and D releases

We have been evaluating the public health situation, and we understand this is impacting our customers. In response to these challenges we are prioritizing our focus on security updates. Starting in May 2020, we are pausing all optional non-security releases (C and D updates) for all supported versions of Windows client and server products (Windows 10, version 1909 down through Windows Server 2008 SP2).

There is no change to the monthly security updates (B release – Update Tuesday); these will continue as planned to ensure business continuity and to keep our customers protected and productive."

See the KB article for the improvements. To download and install the update, go to Settings -> Update and Security -> Windows Update and select Check for updates. The standalone package for this update is available in the Microsoft Update Catalog. In addition, with Windows Update, the latest SSU KB4541338) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.

From CVE-2020-0796 | Windows SMBv3 Client/Server Remote Code Execution Vulnerability:

Quote
A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server or client.

To exploit the vulnerability against a server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 server. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it.

The security update addresses the vulnerability by correcting how the SMBv3 protocol handles these specially crafted requests.

KB 4551762:  This update is for Windows 10 Versions 1903 and 1909.

As described in Protecting users from potentially unwanted applications in Microsoft Edge - Microsoft Edge Blog, beginning with Microsoft Edge build 80.0.338.0, a new feature has been added to prevent downloads that may contain potentially unwanted apps (PUA) by blocking those apps from downloading. Although the feature is off by default, it can be enabled by doing the following:

1.  Open Settings.
2.  Select "Privacy and services".
3.  Scroll down to Services, and turn on "Block potentially unwanted apps".

In the event an app is mislabeled as PUA, it can be kept by tapping "…" at the bottom of the notice shown when an app is blocked and selecting "Keep" > "Keep anyway".

To report the app as safe, go to edge://downloads/, and select "Report this app as reputable", which will result in a redirect to the Edge feedback site.

uBlock Origin Updater has become obsolete · Issue #112 · JustOff/ublock0-updater · GitHub
Quote
I'm pleased to announce that starting from version 1.16.4.17, uBlock Origin for Firefox legacy-based browsers can auto-update itself without any additional tricks. This also means that uBlock Origin Updater is becoming obsolete, and I'm going to make it so that it uninstalls itself on the next update.

I checked Add-ons and, sure enough, uBlock Origin Updater is no longer installed.
