Hello, fellow NUTs!

  This October proved to be a rather productive month, with several
developments wrapped up, as well as some issues with master codebase
behavior created, reported, fixed and tested :)
  While we were not part of some official Hacktoberfest this year, it
pretty much felt like one - great thanks to everyone involved!

  The month is also ending soon, so if we're to follow up with the hope to
release NUT v2.8.1 "during October" - there's only so few days to make it

  People are hereby welcome to give the current code a spin to try and
discover any blocker issues, "or forever hold their silence" (well, till
next release). I'm a bit concerned especially regarding real-life important
behaviors like shutdown handling - there were several layers changes to
`upsmon` regarding support of administrative-OFF, BYPASS and CALibration
states vs. OL/OB and/or loss of connection to data server. Hopefully we
tuned the state machine better with each iteration, but any glaring issues
would better be found and fixed before the release. Some changes also
arrived to the `nutshutdown` script that is typically part of
systemd-shutdown endgame, but could be used in other platforms as well.
Earlier changes since 2.8.0 also touched `upssched` and ability of driver
daemons to initiate shutdown (as an alternative to killing the daemon and
starting another copy for `drivername -K` action which would take time
again to detect and initialize the device), for example, although the
latter is primarily just an option for future integrations and is not
immediately beneficial out of the box today.

  Another important recent improvement is the addition of an `apc_modbus`
driver to support the APC ModBus protocol (currently for read-only
monitoring - I am not sure if development for commands and writable
variables would land before the end of month).

  Generally you can preview the live list of notable changes since 2.8.0
release at
and for things that are expected to impact packaging and upgrades (whether
by possibly breaking disruption, or by adding new ways to automate things
more efficiently that the audience could benefit from) - at
- with such release notes publication also being a recent addition.
