qrencode support is detected automatically; override with
  QRENC=no ./Gridcoin-Research.SlackBuild

Miniupnpc (available on SBo) is optional for UPnP support. Run script as
  UPNP=yes ./Gridcoin-Research.SlackBuild

You will need to edit the configuration file gridcoinresearch.conf
in /etc/Gridcoin-Research/ and place it in your home directory
~/.GridcoinResearch/ to provide the location of your boinc data
and any other configurations that you require. For details, see
https://wiki.gridcoin.us/Gridcoinresearch_config_file and in
/usr/share/Gridcoin-Research-$VERSION/doc/

To enable doxygen to build the HTML documentation, you will need to
install graphviz (via SBo) and run script as

Notes: 
1. New gridcoinsettings.json file
This file contains settings changed by the node while running, and
settings stored in this file override the read-only settings in the
gridcoinresearch.conf file (see changelog and documentation).

2. This is a MANDATORY update.
All mainnet nodes must upgrade before the v13 activation height
(3,989,800, approximately 8 weeks after release). Nodes that do not
upgrade will be unable to follow the chain past the fork height.
