.NET Framework 4.8.1 will be available for the following versions of Windows and distribution channels:
We’re proud to announce the release of PowerShell 7.1, the latest major update to PowerShell 7. This release includes a number of improvements and fixes that build on top of the PowerShell 7.0 release in March and the recent GA release of .NET 5.
.NET applications however rely on the ciphers provided by the OS, and the only way to get new ciphers into the OS is through a patch from Microsoft. Unsupported versions of Windows typically do not receive these patches, so over time you can expect an increasing number of websites to stop working with .NET applications.

} A 2016 study found that the economic impact of Daylight Saving , due to increased heart attacks, workplace accidents and cyberloafing (slacking off at work!) cost the US economy $434 million each year, there are a great many others that present similar evidence.
In 2019 the European Union voted to abolish daylight saving in 2021, similarly the “Sunshine Protection Act of 2021” is gaining traction in the US. Over the next decade I feel quite sure that most of the globe will reject daylight saving entirely.
