I did some more testing:
$ git checkout 2.1.8
Branch 2.1.8 set up to track remote branch 2.1.8 from origin.
Switched to a new branch ‘2.1.8’
$ sudo ./build.sh ospi
Building OpenSprinkler…
gpio.cpp: In function ‘void attachInterrupt(int, const char*, void (*)())’:
gpio.cpp:411:14: error: ‘delay’ was not declared in this scope
Done!
The binary was not updated.
$ git checkout 2.1.7
Branch 2.1.7 set up to track remote branch 2.1.7 from origin.
Switched to a new branch ‘2.1.7’
$ sudo ./build.sh ospi
Building OpenSprinkler…

$ sudo /etc/init.d/OpenSprinkler.sh restart
Checked the UI and it works.
$ git checkout master
Switched to branch ‘master’
$ sudo ./build.sh ospi
Building OpenSprinkler…

$ sudo /etc/init.d/OpenSprinkler.sh restart
