No official change on gambling as far as I am aware.....
Shepherd The Flock 2010 said that it was a "Judicial Matter" and note what they say about employment relating to gambling:
"30. Greed-gambling, extortion: (I Cor. 5:10,
11; 6:10; 1 Tim. 3:8; it-1 pp. 789, 1005-1006; w891/15
p. 22) Christians should avoid gambling in all its
various forms, including lotteries. (Isa. 65:11; g02
7/22 pp. 4-8; w89 7/15 p. 30; g82 7/8 pp. 25-27; g81
11/22 p. 27) If a person makes a practice of gambling
and after repeated counsel unrepentantly pursues a
course of greediness, judicial action would be appropriate.-
w80 9/1 pp. 29-30; w67 p. 356.
31. An individual continuing in employment directly
involved with gambling or employment making
him a clear accomplice or promoter of gambling
would be subject to judicial action, usually after being
allowed time, perhaps up to six months, to make
the needed adjustments. (w95 5/15 p. 23 par. 11; km
9/76 pp. 3-6) In questionable cases it is best to consult
with the branch office."
