Release 1.5.4

This minor release fixes a small bug I noticed while looking back over the blog post from version 1.5.0.

Did you notice it? Go back and look. In the unlumped graph, the two bar counts are 7 and 8. In the lumped graph, the combined count is 17. It should be 15. I can’t believe I didn’t notice that before.

When a person clicks on an answer, creating a dictionary entry, and then clicks the checkbox off again, the dictionary entry is not removed; it’s just set to false. In my new lumping code I accidentally tested whether the dictionary entry existed for the answer, not whether the value both existed and was true. The result was some slightly-off lumped counts, like in the 15-17 example. Sorry. It’s fixed now.

As always, if you find any bugs, please report them on the GitHub issues page.
