apcupsd 3.14.14 Released

The major changes for 3.14.14 are:
  • Mac OS X 10.11 “El Capitan” support
    Installer is now compliant with SIP (aka “rootless”) requirements. apcupsd executables are installed into /usr/local/sbin instead of /sbin. Config files and scripts remain in /etc.
    NB: There continues to be a known issue with USB UPSes under OS X where the OS power management service occasionally does not relinquish control of the UPS, leaving apcupsd unable to communicate with it. The workaround is to unplug and replug the USB cable after booting the Mac.
  • Improvements to MODBUS-USB to improve reliability in the presence of non-MODBUS HID reports and various USB comm faults.
  • Other bug fixes and improvements.

Special thanks to Dennis Wurster (@wildeep) for contributing a nicely-equipped Mac Pro to the Apcupsd project. It was instrumental in enabling support for Mac OS X 10.11 “El Capitan”.

Many thanks to all who contributed. Please see the ReleaseNotes for a summary of changes and the ChangeLog for a full list of commits.

apcupsd 3.14.13 Released

The major new feature in this release is MODBUS USB support. Previous versions of apcupsd supported MODBUS over serial (RS232). This version adds support for the MODBUS protocol operating over a USB interface. Thanks are due to APC for supporting this development work.

Other less visible changes include a digital signature on the Mac OS X install package for compatibility with systems using Gate Keeper as well as many bug fixes and cleanups to the code base.

Please see the ReleaseNotes for a summary of changes in this release. A ChangeLog is also available with a complete list of commits.

apcupsd-3.14.12 Released

apcupsd-3.14.12 is a maintenance release that addresses a number of small issues in the previous version. It also contains a workaround for an UPS firmware issue that causes killpower to execute repeatedly in a loop, resulting in the UPS continually cycling power. The precise list of affected models is unknown, but the Back-UPS BR models are known to be afflicted and likely many other Back-UPS USB models are as well. If you are utilizing apcupsd with a Back-UPS over a USB interface, it is highly recommended to upgrade to this release.

apcupsd-3.14.11 Released

Release 3.14.11 adds MODBUS RS232 protocol support for newer APC UPSes. This release also adds digital signatures on the Windows USB driver and the Windows installer package which should make installation on recent versions of Windows easier.

The MODBUS protocol gives access to advanced UPS features on newer UPSes that previously only supported Microlink. A firmware upgrade may be required to enable MODBUS support on some UPSes. Please see the ReleaseNotes for further details.
