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

I've built it now, but not yet run it.  Anyhow, I take your word that
it's playable and pushed it – 2/3 was already pushed anyways.

Thanks.  I'll have a future update that uses the sources directly as it
fixes an annoying problem with the tire model of the latest release (the
tires get crazy hot and the car becomes uncontrollable); but there's
another serious problem in the unreleased sources where the game appears
to hang on the qualification screen there [0], so it's been on hold
until this gets resolved.

Anyway, thanks for the review/merge.
