PowerShell 技能连载 - 查找最新的 PowerShell 6 发布

PowerShell 6 是开源的，所以经常发布新的更新。您随时可以访问 https://github.com/PowerShell/PowerShell/releases 来查看这些更新。

对于 PowerShell 来说，可以使这步操作自动化。以下是一小段读取 GitHub 发布的 RSS 供稿的代码，它能够正确地转换数据，然后取出这些更新以及下载信息，并按降序排列：

$AllProtocols = [Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'[Net.ServicePointManager]::SecurityProtocol = $AllProtocols $Updated = @{
    Name = 'Updated'    Expression = { $_.Updated -as [DateTime] }
}$Link = @{
    Name = 'URL'    Expression = { $_.Link.href }
}Invoke-RestMethod -Uri https://github.com/PowerShell/PowerShell/releases.atom -UseBasicParsing |  Sort-Object -Property Updated -Descending |  Select-Object -Property Title, $Updated, $Link

结果类似这样：

title                                       Updated             URL
-----                                       -------             ---
