mirai 2.5.1 released.

mirai.r-lib.org

This is a patch release, but brings a new synchronous mode: `daemons(sync = TRUE)` runs your code in the same process. This means you can now drop into a browser session *within* your mirai #rstats code!

p.s. amazing hex stickers made by someone @posit.co!!

My Alma mater has not historically shown much moral fortitude in the face of a big pile of money so I don’t have high hopes about this. Hopefully they find a little spine.
