Sapling yield from oak and birch (others not tested) has decreased significantly. Whereas a 9x9 plot of oak or birch would yield close to or greater than 81 saplings in previous versions, the same size plot now consistently produces around 50% of the planted trees. Although it is purely conjecture, this may be related to decreased mob spawn rates in 1.7.4, which is already a reported bug.
Edit: This issue is much worse in 1.7.2, where yields are closer to 25% of the planted trees

Since the 1.7 update. Leaves yield barely any in 1.7.2 and around 50% of the planted trees in 1.7.4.
Are you breaking the leaves or letting them despawn naturally? You will receive a higher yield if you are patient and let them despawn instead of breaking them.
Increase your sample size. http://youtu.be/p7Zm0xAzjDQ?t=4m

Wait, what? That's news to me, and contradicts the information in the wiki.
Ah, here's Xisuma's video on that myth. To confirm: Sapling drop rates are the same, regardless of whether you break the leaves by hand, or let them decay on their own.
"has decreased significantly" - Since when? What version?
