Greetings Jekyllers! Jekyll v4.2.0 is out!

This release gives you a new hook named `:post_convert` that allows modifying rendered HTML contents before they are
placed into the designated layout(s).

Detecting files that get written into the same destination path has been a part of the diagnostics from `jekyll doctor`
for quite some time now. However, v4.2 has integrated that feature into the build process itself.

On the topic of log output, the `--verbose` output got a bit more verbose. Instead of just showing *documents* that are
being read, the output will now also show *pages* and *layouts* that are being read into the site.

Additionally, we have stopped overriding the `site.url` to `http://localhost:4000` in absolute URLs while developing
via `jekyll serve`.

As always, you can go through [the full list of changes](/docs/history/#v4-2-0) if you are interested in the various
memory-allocation optimizations made to Jekyll.
