+Hello Jekyllers!
+
+Jekyll 4.2.2 has been released. Unlike prior releases, this is a simple maintenance release and may be skipped.
+
+For those who are still curious about the current release, here is some technical context: The previous `jekyll-4.2.1` package was built and
+published using a Windows system. A side-effect of that action was that every file bundled into the gem ended up with Windows-style CRLF
+line-endings instead of Unix-style LF line-endings.
+
+For our end-users, this difference holds no significance. However, a third-party entity vendoring the release faced a roadblock. The executable
+program `jekyll` apparently misplaced the executable bit because of the change in line-endings.
+
+To that end, the Jekyll team decided to use the GitHub Actions service to build and publish releases. In-house plugins have already published
+releases via this route serving as trials. Henceforth, and unless explicitly reported, all Jekyll releases will be built on GitHub Actions'
+Ubuntu platform and published to Rubygems by @jekyllbot irrespective of the maintainer overseeing the release.
+
+That is all for now.
+Happy Jekyllin'!!
+
+*P.S.: Jekyll 4.3.0 will be bringing you some new features very soon.. Also, our sass-converter plugin has been [enhanced][sass-220] to support
+modern improvements to Sass.*
