Piston movement is now prevented if it encroaches across into territories which have the relevant DenyBuild option set (whether faction territory, safe zone, or war zone). This covers piston extension if it pushes across unacceptable borders or even if the piston head itself would cross over, and also prevents sticky pistons from pulling blocks back across such borders.
There is also a new conf.json option "pistonProtectionThroughDenyBuild" (default true) which can be disabled to turn off piston protection. This option is available due to the (untested) potential that a world with many pistons constantly repeatedly firing could result in additional lag from these piston protection events
