+Hey there! We have a quick updated of Jekyll for you to enjoy this January.
+Packed full of bug fixes as usual, thanks to the tireless efforts of our
+exceptional Jekyll community. Three changes to call out:
+
+1. If you're a big fan of [`where_by_exp`](/docs/filters/), you'll be an
+even bigger fan of [`group_by_exp`](/docs/filters/).
+2. Using a custom timezone in Jekyll on Windows? Yeah, sorry that hasn't ever worked
+   properly. We made the internals possible
