The X-Wing also opens another XY-Wing 4-89, pivot r3c8, making r2c4<>4, which also STTE.

Neat! I found the X-Wing of 7's in c49 which opened up the 59-4 XY-Wing with pivot at r2c3 (so r1c7<>4) but then I still had to use the 489 XYZ-Wing with pivot at r3c8 to solve it (r3c7<>4 so r7c7=4). Not as nice as Clement's or lock man's solution though. Good one!
