Moq is a mocking library for .NET Unit Testing (cue the TDD folks reminding us mocks are unnecessary), and it is by far the most widely used mocking library in .NET (475 million downloads vs 87 million for the next largest, NSubstitute). Yesterday, its author released version 4.20.1; which added nagware and a backdoor to Moq, in a bid to drive up paid usages of Moq through ‘Sponsorships’. 

New Features

Comes with Git v2.19.0.
There are now fast, built-in versions of git stash and git rebase, available as experimental options.
The included OpenSSH client now enables modern ciphers.
The gitweb component was removed because it is highly unlikely to be used on Windows.
The git archimport tool (which was probably used by exactly 0 users) is no longer included in Git for Windows.
