Happy new year everyone!
A few months ago I added a heatmap to illustrate quarterly Rubygem release activity in a straight-forward manner:
Since the data still needed to catch up the feature was not really ready for the official announcement treatment upon release, and afterwards I never quite got around to actually write the post - so here it finally is!
On a side note it's great how CSS grid allows to whip up this kind of layout in a responsive manner in the matter of a few minutes :)
I hope this new feature will help you in getting a quicker understanding of recent and historical activity on Rubygems without having to sift through the more detailed data displayed on gems.
