That may be a typo – I think we use the #: part.
Alternatively you could write [arguments]: Add #:configure-flags.

Typo: missing "s" in New variables.

Also, I don't think we differentiate much between variables and
procedures (procedures *are* variables).

I see multiple variants in use.  That's hard for newcomer and bad
consistency, but until someone distills 'The One True Changelog Format'
style to use, I think they are all acceptable.  For example:

'(plib) [phases]: Add some phase.' is common for example.

'(plib) [configure-flags]: New argument.' is similar style.

A more verbose alternative, which is also used could be:

'(plib) [arguments] <configure-flags>: New argument.'

Thanks for taking a look.

In Guix I've mostly seen we differentiate between procedure and
variables in changelog commit messages or documentation, but not between
functions and procedures (these are bunched together).  I think being
more specific as opposed to general helps the reading a bit.

Thanks for the reading.  Did you attempt to build/run it?  It has some
bugs I've reported upstream:

1. (temperature sometimes get set to 'inf' and the driving experience
becomes like ice skating)

2. Occasional crash (segfault) (not reported yet -- couldn't catch a
nice backtrace with GDB).

It's still very much playable though, and upstream is still developing
the game, so hopefully these will get resolved in time.

I'm fine with dropping the [arguments] part, but IMHO the #: marker
should be there, as it marks the thing as a keyword argument (thus also
making arguments superfluous – it's implied).  That is, I'd also write
the phases example as #:phases.

But I haven't done a survey, so if you want to keep the ChangeLog as-
is, by all means do so.

Cheers
